Problem with starting my PC

[Theduco]

Hello , I have a problem with my pc, after turning it on RGB fans will light up for about 5 seconds, then everything goes black for a quick second, and lights up again with nothing displayed on my monitor, I have to reset my computer couple of times to finally see bios screen. I can restart it without any issues, but after long time of inactivity it will happen again. I already replaced my PSU, but it didn't help at all. Can anybody help?

GPU: Radeon XFX RX 580 8GB

 

RAM GoodRam IRDM X 2x8gb 2666

Did you overclock it by any chance? Be it ram or cpu?

First thing you should do, is a CMOS reset.
Take out the battery on your motherboard and simply leave it out for the time of troubleshooting your PC. Then disconnect your PC from the wall and press the power button for a few seconds. That way we can make sure that the CMOS is reset.

 

Now see if that changes anything.

Okay, so I can't speak for your components in particular, nor for them as a whole.

 

But a good start to troubleshooting is:

1) removing ALL unnecessary peripheral devices. Headset? Gone. Webcam? Gone. Usb hub? Gone. You get the gist.

2) if you are willing to, reseat the hardware (mostly the ram, gpu, and power cables) by removing them then putting them back in.

3) go into the bios, and set it to defaults (if you have a raid setup, be careful with this)

4) run the comprehensive onboard hardware diagnostics, see if it catches anything.

 

Let me know how it goes, if it isn't enough I'll give more steps.

Didn't worked

when the screen is black, the speaker doesn't beep

It might be worth it to re-flash the BIOS.

While BIOS corruption is unlikely, it would be nice to rule out.

 

Second, if you can sign into Windows go to Command Prompt as an Administrator and type "sfc /scannow". This is windows system file checker (sfc) and it will scan your windows installation for errors/corrupted files/ some missing files.

If it says it didn't find any errors, then great. if it did, it will try to fix them. If it can't fix all of them, it will tell you that it was unable to fix all of them. Then you need to run the DISM tool in command prompt. "DISM.exe /Online /Cleanup-image /Restorehealth"

This will go to Microsoft and ask for a good copy of the corrupted files so that they can be replaced.

I usually prefer to do sfc, then DISM, then SFC again just in case a corruption kept it from finding another. If the second sfc finds something, then it should fix it.

Also, if it is having trouble just getting into the bios, it might be a good idea to reseat the RAM (take out and put back in).

It might also be worth it to check the CPU for any connection issues (bent pins, dust in motherboard)

 

Take out the graphics card and run it on internal graphics and see if that has any affect.
