Computer Boots Up with No Display, DVD Drive Active, and Auto Shut Down

Hello.

I have the following problem with a computer that is still under warranty.
Everything was fine with the computer until yesterday.
I wanted to turn on the computer and unfortunately I couldn`t.
I turn on the computer, it seems to work, this sound starts (a mechanical one, maybe it`s a disk or a drive, the same as usual, but it`s not the sound signal.) the DVD drive turns on (i.e. the light blinks and you can hear it checking if there is a disc)
unfortunately the monitor does not turn on, it means it is turned on but there is a black screen, only the light blinks, it is probably called "stand-by" (sleep state), the bios does not appear on the screen, you cannot enter the bios, the keyboard it doesn`t work either, because there is no blinking of the lights and "del" to enter the bios setup does not work. The computer runs like this for 1 minute, that is, every now and then the DVD is turned on and after a minute the computer turns off completely, but after about 7 seconds it turns on again and the same thing happens over and over again.
The computer is under warranty and has a seal, so I can`t open the cover and see what`s going on inside, the fans must be working because when I put my hand on it I can feel a breeze.
The computer is a year old, detailed technical data is presented below:

I guess it won`t be possible to do it without warranty, there shouldn`t be a problem with it and they should do it for free?
What could have gone wrong?

Hello!

I had a very similar case with my friend who asked me for help.
The symptoms were identical to yours.
I, like, don`t know why the first thing I checked was the RAM memory, I put out one cube and the computer started up but it hung up after a few seconds, then I reset its Bios by removing the battery from the motherboard for about 15 minutes and then everything returned to normal, the computer works without any problems to this day And the Rams turned out to be 100% damaged because they didn`t work for me either
In your case, however, the power supply may very well be damaged, I had a case where after turning on the computer, after 10 seconds, resetting and replacing the power supply solved the problem, because after disassembling it, 5 capacitors were bulging
It may also be a damaged graphics card As you can see, there are many possibilities and since your equipment is under warranty, opening the casing is not an option, take it to the service center and let the boys spend a little time there :)

Regards!!!
I wish you good luck and a quick repair :)

It is also possible that the motherboard was also damaged during the overvoltage - this is not certain (all components are based on the motherboard.) Therefore, you should not turn on the computer again. The service will decide the rest.

Robas24 I had a damaged motherboard and power supply, and unfortunately even minor damage to the motherboard often ends with almost nothing working except the power supply (in the case of wawrzyniaczek27, the power supply was definitely damaged, a given power supply line must have failed, from what I concluded, the hard drive works, i.e. the +12V1 line is intact, but if the monitor does not turn on, the line supplying the graphics card +3.3V or +5V may have failed) in the motherboard, unfortunately everything must work together and in my opinion the motherboard is intact.

Wawrzyniaczek, if you have the opportunity, check whether there is USB power supply if there isn`t (+5Vsb means that we can start the computer with this voltage) then the line responsible for the graphics card and hard drive electronics is definitely broken, so Windows does not start either (do not confuse it with the sound coming from the hard drive, because this sound is caused by the drive motor which is powered by voltage of 12V). So you can do it, for example, with a pendrive or an SD adapter with an indicator LED . This would be helpful for us and we would know where we stand

And the best and fastest solution will be to visit warranty specialists The power supply and its sector are 100% dead, the motherboard should work, as for the BIOS, I agree with your helpers above, this issue may be solved by removing the battery for about 20 minutes.


I wish your computer recovery

I agree with my friend. How long is the warranty for the power supply? kuleeQ "unfortunately, even minor damage to the motherboard often ends with almost nothing working except the power supply." It`s not quite like that. It happens that, for example, the BIOS crashes later. Depends on the damage. But that can also be the case.

I had a 1-year warranty on the power supply and a 2-year warranty on the motherboard. I don`t know what it`s like when you have a new computer because it usually lasts 24 months. It probably depends on the whole thing (including the power supply). If Wawrzyniaczek`s friend has a one-year-old computer, they will accept it without any problems. Of course, my friend, don`t tell me how it happened, that it doesn`t work, whether there was a storm or a power surge, or that you dropped the computer because of such a state of affairs, the service technician may reject the warranty, the best thing to say is that I turned on the computer and suddenly it stopped working, I don`t know what happened :(

Added after 4 [minutes]:

of course, there could have been a small overvoltage that did not damage the semiconductor elements (which is really rare due to the low resistance to puncture of the NP / NPN or PNP connectors) on the motherboard, but the BIOS could have crashed because of this incident.

Are you sure that breaking the seal voids the warranty? I have already encountered Windows NTT System seals and breaking them did not result in loss of warranty, you must have access to clean the computer, perform diagnostics and so on... I personally open such seals, take out the battery (of course, disconnect the power supply), wait for a minute and try to turn it on. ..unfortunately, if you hear the sound of turning on the computer, it is possible that the power supply is working... maybe the disc has gone bad and is not transmitting the signal to the graphics card... disconnect the card (if you have one), connect the monitor to the integrated one, disconnect the DVD and all USB devices and turn it on ...the keyboard must be on the "old" connector, not USB, and try... if not... service.

And I have a different opinion...

If the computer is under warranty - why bother???
It`s best to take it to the service center and let them worry - we don`t pay anything for damaged elements anyway.
And attention!!!
There is no warranty shorter than 24 months!!! (Act on special conditions of consumer sales). Even if the equipment manufacturer only provides a one-year warranty, the seller is responsible for the equipment for 24 months!!!

Likewise, if the service/seller determines that the cause of the failure is, for example, a damaged keyboard, the seller should cover the costs of repairing the equipment that the keyboard (or other device/component) damaged.

I have been working in the warranty service for many years, so my knowledge is not completely unknown.

@ Wawrzyniaczka - do not try to diagnose faults yourself, take the computer to a service center under warranty and upon receipt, request a repair report detailing the damaged components and activities performed (e.g. replacement of RAM symbol, etc.). For such a replaced component, the warranty runs anew, and for the rest of the equipment it is extended by the time that has elapsed from the date of returning the equipment to the store or to the service center until the date of its receipt!!!
The same if they replace all your equipment - the warranty starts anew from the date of receipt.

And for people who clear the BIOS by removing the battery - wouldn`t it be easier to use the CLCMOS (Clear Cmos) jumper??? Not only is it faster and easier - it`s even safer. We avoid a situation in which there is a sudden overvoltage when inserting the battery into the socket (3V voltage can also cause small sparks - to put it simply)

I turn on the monitor, the computer starts up, the DVD LED blinks as usual, but the monitor doesn`t turn on and the system doesn`t load, it looks as if it was checking the DVD and didn`t want to start. Restarting the BIOS by removing the battery worked, but after patching the system and restarting, the same thing happens again, the computer won`t turn on ... Help me

Phew, I haven`t been here for a long time and this topic is probably out of date, but out of curiosity, maybe you can tell me if you removed the system installer from the drive after installing the system? and have you tried disconnecting the dvd? In general, you can write how this whole situation ended and I`m sorry that I`m only replying now.
