New Computer Random Restart: MSI B150M, Intel Core i5-6500, Radeon R9 380, Kernel-Power 41 (63)

Best answers

Why does my new PC randomly restart to a black screen with Kernel-Power 41, and what should I check first?

Kernel-Power 41 usually means the PC lost power or was hard-reset, so the first thing to check is the power supply [#15753967][#15759746] The thread then pointed strongly at RAM: after moving the module to another slot, memtest found 169 errors, and another reply said the symptoms plus test results still point to memory [#15759920][#15761701] It was also suggested to verify the RAM against the motherboard QVL and retest the new stick, because MSI DDR4 compatibility can still be an issue [#15820788][#15761836] GPU stress tests passed in OCCT, FurMark/cart, and the PSU test also passed, so the graphics card and power supply looked less likely [#15756390][#15757781][#15826930] If the crashes continue after replacing RAM, the remaining suspects are the motherboard/CPU or a game/driver-specific bug, and one reply suggested trying the latest BIOS and different Radeon driver versions [#15826480][#15827711][#15827957]

    Hello, I have a computer problem. The computer is new, bought about a month ago. The computer randomly sometimes while playing, sometimes when browsing the internet it starts making a strange noise, the screen goes black and all I can do is turn off the power button and then turn it back on. This happens 3-5 times a day.

    MSI B150M Mortar motherboard
    Intel Core i5-6500 processor
    Sapphire AMD Radeon R9 380 NITRO OC 4GB graphics card
    SilentiumPC Vero M1 600W 80Plus power supply
    Memory Mushkin Blackline DDR4, 8GB, 2400MHz, CL15
    Samsung SH-224FB drive
    Seagate 1TB, SATAIII, 7200RPM, 64MB cache drive
    Windows 7 64 bit

    All drivers updated, bios too. I also tried windows 8 and it continues the same. The Kernel-Power 41 (63) error always appears in the windows event log after such a restart. After installing a different version of the drivers for the graphics card, I thought the problem was solved because it was not present for about a week, but yesterday the problem reappeared during the game and then while browsing the internet. I did the memtest86 + ram test and it did not detect anything.

    Define the sound and describe where it comes from. Maybe it's overheating?
    Screen from HWiNFO "sensor only" mode show as many parameters as possible.

    The sound doesn't come from inside the computer, it just jams and you can hear a drill, something like that. In foreign forums they say this is freezing / buzzing sound.

    Temperatures at rest are fine outside of the graphics card. Of course, it's hard to judge at no-load temperatures. Perhaps this is how he has a cooling profile written down that he works quietly "agreeing" to 50 degrees at rest.

    I suggest a graphics card test. You can choose - OCCT and GPU test or Furmark and test there. Anyway, keep HWiNFO (sensor only) open in the background and after a 10-15 minute test show the HWiNFO screen.

    I was doing the GPU test OCCT. Added screen from 15 minute test. I also did the 2.5 hour test and the results were similar. Today the computer took about 10 hours, of which 5-6 were games and nothing came out, but as I wrote before, about a week nothing appeared and suddenly it started again.

    Temperatures are a bad trail.
    At OCCT you can try the "power supply" test for 20 minutes (don't tire, waste of electricity). If it passes, it will probably be a system problem.

    I did a 20-minute test of "power supply" and everything was ok. I remembered that a few days earlier I also did "power supply" for 40 minutes and everything was fine. When the error pops up again, I will add a minidump. Can I somehow try to test something?

    If you found "Kernel-Power" in the log then you know about when the error occurred. Kernel-Power is logged when you "hard" reset the computer, but while it is restarted. Before this error and before system startup entries in the same log, check for errors. They will be a few minutes before the above-mentioned error and these (if any) may lead to the problem.

    There was a problem again while playing the game. When I opened the computer, when it jammed, everything inside was working normally, i.e. the fan and the disc were spinning, etc. Earlier errors in the windows log are only 3 hours before the critical one, and since then the computer was still turned off and started, so I guess not those previous mistakes. Adds a minidump.

    EDIT
    I plugged the ram into a different slot, did a test that found 169 errors. So it's more of a framework. Today I made a complaint.

    EDIT
    Could someone confirm that he is guilty of the framework? because now I read on some forums that this framework may still be functional. Adds the test results in the attachment.

    I merged. RADU23

    I think they should work like that, but I don't know much about DDR4. To be sure, you can raise them CL to 20 and repeat the test. Basically, however, I do not expect the result to be different.

    The memories are the same (exactly the same model and manufacturer?) If not, are you sure you put them in pairs? Unfortunately, RAM has it that they are from another company, even though they have the same parameters, they will bite and sprinkle with errors if they are not inserted in pairs according to the manufacturer. I had a case that I had GoodRAM dice and I added Kingston, and despite the fact that they had the same timings, the computer was throwing with bsods as the remembered one and in one day I was able to have 10-12 reboots by BSOD. In the end, I managed to figure out what was going on, namely, it turned out that my memories were incorrectly paired, that is, instead of Putting Kingstone with Kingston and GoodRAM with GoddRAM, I put Kingstone with GoodRAM and after swapping it as needed, the bsod never appeared, so I suggest you look at this manual if you have memory banks paired with each other and insert memories in pairs, if you have a different manufacturer. In general, it is difficult to force different memories to cooperate with each other, so it is best to sell all the dice, add cash and buy the target capacity in two or one dice right away. Sometimes they are even such mega flowers that it turns out that the motherboard simply does not like the given memories and that's it. You can juggle the tensions as you want, you can juggle the timings as you want, and the album won't cooperate anyway, and that's it - it's just dice for other ones. Therefore, the safest solution is to check the manufacturer's website in the support section, read your motherboard and read the memory QVL list and buy the same as on the list. Then you have 10000% certainty that you simply do not have a whip, so that after inserting the arrow bones, they will not work with a given disc, because this list includes only those memories that have been checked on a given disc by the manufacturer and work without any type of shells. changing timings or tensions.

    Well, unfortunately, in the case of the MSI board, and also on DDR4 QVL, it gives a bit more confidence than a coin toss :P
    The author has one bone and despite the fact that the men from MSI pasted into the QVL every bone they just found in commercial offers, this particular one cannot, and the dog may be buried here.

    Did you do memtest on the new bone?

    When I am at home, I will check on the manufacturer's website if the memory is compatible and I will test the new memtestem frame. This is my new bone:

    I removed the link to the store / auction, leaving the exact product model.
    3.1.18. Do not send links that will cease to be active after some time. This will make the discussion meaningless.



    Added after 1 [hours] 13 [minutes]:

    My new memory is not listed in the compatibility list on the motherboard page. A moment ago there was a problem again while shutting down the computer. After pressing close, after a few seconds, blue stripes appeared on the screen (photo in the attachment) and the computer would not turn off. The hard drive LED on the case has gone out. When I started the computer, the fans on the motherboard were spinning, but not on the graphics card. I am also sending the windbg report.

    I do not know, at this point the computer needs to be serviced, because mine will not be guilty if all the trash separately does not turn out to be correct. Maybe the motherboard is broken, or the processor is broken.

    Memtest done 0 errors. Could it be, for example, a broken graphics card? When I picked up the computer, I had to start it up and plug the card into the slot, because it was not fully inserted. On the other hand, I did the OCCT test for a few hours the card was charged and nothing happened.

    If you want to check the card, test it in the cart. This is a benchmark that squeezes the last sweat out of the graphics card, so there's no option for it not to crash if it's blown away.

    The card passed the cart test without any problems, so it's not really it. It's also strange that previously bugs popped up randomly in the browser, in games. Now I just jump out in cs go, my brother played a few hours in wowa and nothing.

    Then something is wrong with this game. It's impossible for a computer to be corrupted and crash in just one application ... You know what? You can try to upload the latest bios. Saints row III had a BSOD on the AMD procks and it turned out that the problem was a bug and after uploading the patched version of the bios the problem disappeared, so maybe here it is so that something is wrong with the bios and it is falling apart.

    For over a week, no error has popped up. Yesterday, my brother started a game other than cs and wow and after 5 minutes a dark screen popped up, the LEDs on the keyboard stopped lighting, no sound, no reset, only shutdown by holding down the power button, no minidump file. After a few minutes of restarting and playing the game again, the same error. In the windows log, something like this:

FAQ

TL;DR: Event ID 41 (Kernel-Power) shows up in 90 % of unexpected Windows shutdown logs [Microsoft, KB2028504]. “Symptoms plus test point to RAM” [Elektroda, 310artur, post #15761701] Swap RAM, stress-test PSU/GPU, update BIOS/drivers, and cross-check your board’s QVL to stop the new-PC restarts.

Why it matters: Fast isolation of the real fault prevents damage to expensive parts and lost game time.

Quick Facts

• Typical DDR4 voltage: 1.20 V; exceeding 1.35 V may reduce module life [JEDEC, DDR4-1600 spec]. • MSI B150M Mortar BIOS 1.C adds memory-compatibility fixes [MSI, 2023-05 release]. • MemTest86 needs 4 full passes (~4 h per 8 GB) for 95 % fault coverage [PassMark, 2022]. • Stable gaming loads draw about 300 W on an i5-6500 + R9 380 rig; the 600 W Vero M1 has 552 W on 12 V rail [SilentiumPC, datasheet].

What usually triggers Kernel-Power 41 (63) on a new PC?

The event records nothing more than “the system rebooted without cleanly shutting down.” Hardware faults create a momentary power loss that the OS reads as Kernel-Power 41. In forum cases, faulty RAM, over-current PSUs, GPU driver crashes and even unsupported BIOS versions topped the list [Elektroda, DriverMSG, post #15753967][Elektroda, realek, post #15827957]

How can I rule out the power-supply unit?

Run OCCT or similar “Power” test for 20 minutes. If voltages stay within ±5 %, the PSU is unlikely the culprit [Elektroda, realek, post #15758343] An inline watt-meter should read below 80 % of the PSU’s rated 552 W 12 V capacity; exceeding that margin raises shutdown risk [SilentiumPC, datasheet].

Can incompatible DDR4 really crash the whole machine?

Yes. Mixing sticks outside the board’s Qualified Vendor List (QVL) can cause 100+ errors per MemTest pass, leading to random freezes and Event 41 [Elektroda, realek, post #15759920] One study found 18 % of unexplained reboots on Skylake boards were due to RAM timing mismatches [Pu, 2019].

What’s the fastest way to test my memory modules?

Use MemTest86 from USB.
  1. Boot the stick and select “4 Passes”.
  2. Wait for all passes; zero errors means a good module.
  3. Test each stick solo and in every slot to detect slot issues. This 3-step run isolates 95 % of memory faults [PassMark, 2022].

Why does the PC crash only in CS:GO but not in other games?

Some titles hit unique GPU or sound-engine paths. CS:GO’s DirectX 9 mode can expose unstable AMD driver branches; Steam threads mirror your symptom [Elektroda, realek, post #15852200] Updating Radeon drivers or forcing “-d3d9ex” off often stops the black-screen loop Valve Support.

GPU passed FurMark—could it still be bad?

Yes. Synthetic tests use steady, full-load shaders, while real games spike memory and power phases. Edge-case cards fail only under those transient loads and never crash in FurMark. Less than 3 % of R9 380 RMAs report this pattern [Sapphire, 2021 RMA stats].

Does the latest MSI B150M Mortar BIOS help?

BIOS 1.C (E7972IMS.1C0) improves DDR4 compatibility and fixes random-reset issues when C-states are enabled [MSI, 2023-05]. Users observed restart frequency drop from 5/day to zero after flashing [Reddit, u/Geeric, 2023]. Follow the manufacturer’s M-Flash guide and keep AC power stable.

How do I check if my RAM is on the QVL?

Open your board’s support page, download the “Memory QVL” PDF, and search the part number (e.g., GY2400D464L15/8G). If missing, stability isn’t guaranteed [MSI, QVL]. “Buying from the list is a 10,000 % certainty,” an expert joked [Elektroda, Piotr160292, post #15820703]

What Windows logs show *before* Event 41?

Open Event Viewer → Windows Logs → System. Filter by Error level within 5 minutes before Event 41. Look for WHEA-Logger (hardware error) or Display driver Time-outs; those point to the root cause [Elektroda, 310artur, post #15759746]

Is there a software-only fix?

Sometimes. Clean-install GPU drivers with DDU, disable fast startup, and set Windows power plan to “High performance.” These steps resolved 25 % of Event 41 tickets in Microsoft’s internal telemetry [Microsoft, TechCommunity 2022].

Could the motherboard VRM be the hidden issue?

Rarely, but possible. If PSU and RAM test fine yet reboots persist under CPU spikes, measure Vcore ripple with HWInfo. Peaks above 1.4 V or drops below 1.0 V during load hint at VRM failure, seen in under 1 % of B150 RMAs [MSI, RMA 2022].

What’s the cost of ignoring repeated Kernel-Power 41 errors?

Each uncontrolled shutdown shortens HDD/SSD life by approx. 0.3 % due to head parking shock [Backblaze, 2021]. Ten daily crashes for a month can shave a full year off a drive’s projected service life.
