I get this (pic taken a bit after.) Comp locked down, and gave me the blue screen of death. I booted it in safe mode, ran avast, and it found nothing. I then did a system restore (which I could only go back about a week, which I found odd.) After the system restore, everything worked fine for about 4-5 hours, then bam. It was back. About 10 seconds later, the screen started flashing green and black pretty rapidly. I could see something about “your comp has gone into the infinity loop.” I then killed it and rebooted in safe mode, and re-running avast.
So my question is, what the hell is going on? Never had anything like this before.
I’d say: hardware prob, most probably the graphics card or a temperature problem (does this happen, when the PC has been started and still is cool or does it happen only after a certain time powered on and used?)
don’t look further, it’s your graphics card that’s toasted (onboard memory more likely than GPU). It will come back to normal off and on but as soon as it will go beyond what use to be a supported temperature (but is not anymore), it will produce those artifacts.
I agree to Logos. That’s it by 95%.
There is a low possibility that your PCI-E Slot is the troublemaker, but that’s not too likely.
It is not an onboard-graphics-adapter, right? So the easiest way to check would be to take your graphics card and stuff it into some other pc and test it.
The motherboard may appear to be all messed up. Reassemble and rebuild the entire PC, format, and reinstall Windows, take it to a computer repair shop to have them rebuild it for you, buy a new PC and use the main hard drive as a slave.
Here’s are some DIY if you can’t afford to take it to a repair shop:
