[Solved] Computer Won't Start: Gigabyte GA970A-DS3, AMD FX-4350, Radeon HD7850, Fans Spinning, No BIOS

Hello, computer about 3 years old, first configuration:
Corsair CX 500 Power Supply (500W)
Motherboard Gigabyte GA970A-DS3
AMD FX-4350 processor, socket AM3+, 64bit, 4.2GHz, 12MB cache
Graphics Gigabyte Radeon HD7850 2GB (GV-R785OC-2GD)
ADATA Premier Memory, DDR3, 8GB, 1600MHz, CL11
Seagate Barracuda 1TB drive, already chirping slightly
Some kind of multi recorder and memory card reader
Large housing, no additional fans

And now the problem.

On Thursday, normally used for gaming, net, etc. Turned off for an hour after only net (so not after stress).
He didn't get up on Friday. Symptoms:
1) All fans are spinning when turned on (but on the graphics, they slow down for a moment about every second)
2) No signal to the monitor and no signal from the speaker on the board, the BIOS does not start
3) The drive light on the outside of the case is not blinking
4) Hard chirps for about a second and then silence
5) The optical drive allows you to eject the tray up to a second after starting, then it does not respond

What I did:
I disconnected the disk, optical drive, RAM and graphics card (together and individually), no reaction (of course, without a graphics card, I can't check if there is a signal to the monitor, because the motherboard has no video output)

The processor has box cooling, in addition, about 4 months ago, when blowing through the heatsinks, I damaged the original PWM proc fan (it vibrated under stress, made a lot of noise, as if a neighbor was drilling with a hammer in the wall) and replaced it with a 3-pin one, set to silent in the bios.
The motherboard does not look damaged, the capacitors are not swollen and not spilled. The power supply checked by a guy who repairs a PC (but he has not accepted it for repair yet, he is busy). He advised me to order a new processor.

My suspicion also falls on the procek, it is possible that I finally fried it with worse cooling (silent, without PWM). In fact, I already ordered a new processor (maybe too fast? AMD FX-8300 3.30GHz 8MB BOX 95W)

When disassembling the CPU heatsink, the heatsink came out of the AM3+ socket together with the CPU!

After unsticking the processor from the heatsink, I tried to install the processor itself. When the PC is turned on, the process continues to warm up slightly, the PC does not start.

Oh, the system is a seven, I also pulled the battery out of the board. PC never overclocked. System not reinstalled (was already in bad shape)

Hello

Unplug everything possible and listen to the sound the record makes. loud on startup.

Connect the system speaker (e.g. buzzer, etc.) to the 4 Pin (2Pin) on the motherboard and listen to the sounds after starting the PC.

Bios beep codes: http://active-comp.pl/bios.html

Install the cooler on the processor. Running a 125W heater without a heatsink is a very poor idea.
Remove the RAM from the motherboard, turn on the computer without memory. Does the disc squeak?
Blow out the memory slots, reinstall the memory in other slots than they were (if they were in white - move them to blue, if they were in blue, then to white). You can test on one memory module, run once with one memory in the first slot counting from the processor, if it doesn't help, move the memory to the second slot and run again. All manipulations with the disassembly/assembly of the memory should be performed with the power cord disconnected and after the switch has been flicked.
Clear CMOS settings properly. Disconnect the computer from the mains, flick the switch (to discharge the capacitive elements in the power supply to zero). Use a screwdriver to short the two pins labeled CLR_CMOS, they are near the connector where the front panel cables are connected:



Try booting the board from the stock BIOS, the board comes with two BIOS chips.

Method one:

- Turn off the PC
- Press and hold the power button and do not release it until the computer turns off.
- Press the power button again, the computer should boot from the stock BIOS.

Method 2

- Turn off the PC
- Press the power button and the RESET button simultaneously and hold them down for 10 seconds
- Release both buttons, the computer should boot from the stock BIOS.

As I wrote, I gutted it from what I could, only the processor, the motherboard, and the power supply remained. I disconnected the SATA connectors from the drive and the drive, the USB cables from the ports on the front and the card reader. Removed RAM and graphics card, The speaker is connected to the 4 pin connector as shown below. The only thing connected (and you can see in the picture) are the cables from the power switch, reset and status LEDs on the front of the housing

No sounds.

PS When I try to start the PC, I turn it on only for about 10 seconds, if it does not start, I turn it off with the power switch, I also monitor the temperature of the processor, it is warm / lukewarm.

I cleared CMOS as you wrote, method 1 and 2 does not work in the sense that it is unchanged. No acoustic signals. The connected monitor does not turn on (I installed graphics and a heatsink with a fan on the CPU)
Earlier recording, when turning on the PC without graphics and RAM. You can only hear the disk booting for a second.

Is the cable from usb 2 port disconnected? if nothing beeps, it does not detect the processor or the board is beaten. When I worked in the service, I unscrewed the board from the housing and connected the basic components on the side, you need to look at the board very carefully. Of course, once again remove the battery after disconnecting all power to the board and wait for 2 minutes. Connect the power supply, processor and processor power, buzzer and turn on. We'll see if the buzzer answers...

Yes, maybe the picture is hard to see, but I disconnected all cables from the board, except for those that go to it from the power supply and left only the front panel (power, reset and status LEDs). Only motherboard, processor and power supply. I just disconnected the USB cable so as not to wonder where it was plugged in.

Since the PC didn't turn on on Friday, the on-board speaker hasn't sounded once.

Majcin, I also did the variant with the battery, it was my first step. Whether with full equipment or with gutted, removing the battery does nothing.

With full hardware, when the fans are spinning, I don't know why, 2 fans on the graphics, pulsating. Ie, they spin normally, and every about a second they apparently slow down for a fraction of a second and then accelerate.

can you connect another power supply?

Not really, the guy was just checking the voltage on what is now some device with diodes and a smartphone-sized display (it wasn't a multimeter). According to him, the power supply is ok.

I have a strange suspicion myself that it's a hot proc. On an old fan with PWM, under stress, e.g. when playing War Thunder, he could get pretty fat, even when he was in good working order. I suspect that the "budget" replacement of only the fan with a regular 3-pin non-PWM one and the Silent setting in the Bios of this fan could cause cyclical overheating of the processor.

I remember when I was stressed I checked the temperature with speedfun or something like that. And on the new fan it was around 60-65 degrees after 5 minutes of stress on the processor.

Have you tried booting the board in the stock BIOS as I wrote earlier?
The processor has overheat protection (although using a weak fan on a 125W processor is a terrible idea), but if it was 65 degrees under load, it's still not a bad temperature. I would be more worried about the CPU power section - it is not cooled by heatsinks, and with such a processor it requires good ventilation.

Yes, I tried what you suggested with flashing the stock BIOS, both variant 1 and 2 plus resetting the CMOS. No effects.

Anyway, I ordered, maybe too hastily, a new processor, a bit better than the current one, 8-core AMD FX-8300 3.30GHz 8MB 95W, a bit less power-hungry. The old one was a quad-core AMD FX-4350, 4.2GHz, so it would fit AM3+.

Let it not be an unnecessary expense if the problem turned out to be the motherboard.

I had plans to modernize the graphics, and here the expense fell out.

If it starts after replacing the processor, I'll add an SSD at the same time.

First, replace the power supply with another one.

Then hopefully you ordered a refundable processor. Motherboards fail more often than CPUs (although CPU damage is certainly not impossible). And replacing the motherboard with another one for AM3+ makes little sense, it's better to add some and replace it with something better. So it's best not to make decisions too quickly

The guy who checked the power supply did not have as much power as mine to replace it to check the board. Tomorrow I will try to take the PC to another one.

I ordered the processor via the net at X-KOM

The motherboard with the CPU and RAM alone will not load your PSU beyond its means. Unless you have a short circuit.

Rather a power supply, chieftec did the same for me and it fits me like a glove.
https://www.elektroda.pl/rtvforum/topic3551388.html but it's just a suggestion.
I also have a monitor, it also has a problem with turning on - you mustn't turn it off, because it won't turn on later, but once it is, it works 24/7 - until the next turn off and miracle with turning on again.
Seriously, none of your friends have any power supplies?
The computer guy?
Any shop nearby?

I'll know more tomorrow. In the town where I live (10k inhabitants) there are 3 places where they fix PC. Only 1 point was open on Saturday. Now I'm typing from my sister's laptop that I borrowed.

These are omens, there are no rules. You need to replace the power supply and physically check.

That's why I'm asking about borrowing a power supply, checking it on another one, not buying it. I had a similar problem myself, because I had old power supplies.
OCZ fell shortly after the warranty, I replaced it with chieftec GPS400W ?? This one after half a year started to "turn on"... It's a modecom, but probably the one from the best series, in the end it ended up in a PC.
And together, it must have been so sausage over the course of a year...
Am I entitled to be prejudiced?
I think so ?

Diagnosis cannot be biased. The fact that a colleague had to juggle power supplies does not mean that everyone's black screen is a power supply failure. Without diagnostics, all or any of the suspicious components may be damaged - the processor, motherboard, power supply, possibly even RAM. So sad experiences have no meaning in the context of the Author's problem, the fault can be eliminated by replacing each of the components in turn and testing the computer's operation.

Maybe you have a blown system speaker or buzzer, because the POST procedure (motherboard and components test) always ends with a sound, no matter if it is correct or with an error.

You can check the condition of the HDD and possible damage using MHDD. Windows does not repair disks and sometimes do not scan, because you will worsen the condition of the HDD.

MHDD - diagnoses, scans the disk condition and repairs - RECOMMENDED - info. http://forum.komputerswiat.pl/topic/17548-opis-programu-mhdd-i-technologii-smart/

Until the failure of the loudspeaker "give voice".

I'll let you know tomorrow what I find out.

As for the HDD, although it's 1TB and half is full, I'd lose some data, but nothing critical. Anyway, if I fix it, I will add SSD as a disk for the system and the most important programs, I already have it purchased, I wanted to add it a long time ago

Added after 19 [hours] 19 [minutes]:

Checked the power supply by connecting a different (new) one instead of the old one. PC still won't wake up. No changes, i.e. the power supply is not released. The circle of suspects, in my opinion, narrowed down to the processor and the motherboard (the motherboard becomes more likely). I canceled my CPU order.

I left my PC at a computer repair shop. More will be known tomorrow. I will inform.

The record fell. I replaced the motherboard with a newer model, a new processor for AM4 plus replacing the RAM from DDR 3 to DDR4. The rest of the components (including the graphics card) are left for now. I added a 480GB SSD for the system and the most important programs, an old disk, as a data store mainly for multimedia.

By the way, I installed Win 10 instead of the old 7.
