PC crashed and can't start (no BIOS)?

Re

I have the following problem. When I just looked at Netflix on my Acer PC yesterday, suddenly the screen turned black and the illuminated LED keyboard / mouse also failed. The PC was definitely still running, because he then "up" for a few seconds and then calmed down again. I have him afterwards with the on / off switch and reverted from the network. After I infected and started it again, the following happened:

Again "yelling" the fan and then calmed down, mouse and keyboard remained black, that is, the LED lighting has not been addressed. There was no whistling sound from BIOS and generally neither the classic bios screen or anything else appeared on the screen, say, I could not even go into the BIOS, even if I wanted. I'm completely at a loss what the problem might be.

-) Power supply unit defective? Unlikely, because then the PC would not start. This is supported by the fact that the lighting of the externally connected devices does not "start". (When the PC crashed for the first time, I feel like I heard a "click sound", almost like a FI switch falling or burning a light bulb, but I do not want to worry about it really being that way.)

-) BIOS battery empty? Maybe, but that does not explain why the PC simply smears like this during operation. In addition, an empty BIOS battery on other PCs has so far only had the effect that the boot process took longer and the clock was reset.

-) Motherboard defective? Maybe, I have not had that case yet.

-) Hard drive defective? Rather not, because then the BIOS would work and an error message will be issued.

-) Graphics card defective? Then probably the standard built-in chipset of the motherboard would still work…

Tomorrow I will definitely plug in the hard drive to an external adapter and see if I can downplay the data. The whole situation is very "modest" because my old PC broke the hard drive two years ago and I bought the current Acer PC. I had to send in the first time after a day because the BIOS software was outdated and the PC is no longer started. And now, of course, the warranty is almost expired and the PC broken again. I could cry.

Regardless of what device specifications my PC has, is there an IT specialist among you that could tip me in the right direction as to what the problem might be? That a PC does not start at all I had in my career still not at all.

Spontaneously, I would tap on a defect on the motherboard or power supply. Graphics card, RAM and graphics card would output a whistling sound.

No picture - graphics card. -> Remove and test with internal graphics unit. This is disabled by default when a GPU is detected. Incidentally, the internal one sits in the CPU and not in the chipset.

CMOS reset performed?

So first the following;

if your power supply gives off, it works properly first. If your keyboard does not work, I would spontaneously type out, why you do not even come into the bios. Often, a broken (usually it's always keyboards with extra features) keyboard blocks the entire boot process when connected.

So try to work with another keyboard and mouse first. The battery from the bios is ok. If it was not like that? It would only indicate that you have to correct the BIOS settings every time again and again and that is not the case with you, because you are not even so far.

Turn on your PC and pay attention to whether your PC on the motherboard can "explain" itself with the help of some boot LEDs. Because some MBs light up the associated LED on the board at each initialization step. If the graphics card is to be detected, the GPU LED will light up, the memory will do the RAM LED, etc.

Pay attention to whether your MB offers something like that. Sometimes a red LED will signal a recognition error.

My order to exclude errors is therefore the following;

keyboard and mouse

random access memory

HDD / second hard drive

graphic card

Just plug one close to the other and try to start the computer after each time to find the culprit after the exclusion procedure.

Always calm with the young horses, such facts can be explained quite normally. For this neither bold nor exclamation marks are necessary. BIOS reset done?

Su

In certain communities, certain facts are passed on incorrectly. So a "freeze" of the calculator is not a crash, but a freeze of what you see (picture exists, no reaction of the input devices).

But just because some want to feel cool with technical terms and Anglicisms, use them as lay people and contribute not to swarm intelligence, but to swarming.

Is nobody more interested in simple, clear and unreaded words anymore?

po

I have also referred to the CMOS RAM, but by linguistic use, this is shortened referred to as CMOS.

Re

The keyboard and mouse are definitely not, because they are brand new and apparently have not been powered up. Interestingly, since early this morning, the PC starts again as normal. I will follow your advice with the MB-Leds and watch the next time the error occurs. In fact, I did not know that the MB itself also has LEDs on the plant. In the future I will also test for the exclusion principle.

Su

Ok, but just because the keyboard and the mouse are new does not mean anything these days. Bad processing is always given somewhere. And that does not have to be with the LEDs, it can be if your motherboard is a good one.
