The other day I set some video files converting, around 15 minutes later I noticed that the PC had turned off and the 2 front LEDs were flashing. I turned the power off and restarted it (The GPU made a loud whirring noise as if it had overheated) and everything worked fine until about 1 minute 20 seconds after logging in the display just cuts off. The fans and LEDs are on but no video and holding the power button doesn't turn the PC off, I have to do it at the mains. I tried this a few times and it always cuts off at 1 minute 20 after logging in.
I have tried -
- re-installing the GPU drivers (still fails)
- using a different GPU in the PC (still fails)
- Using a different hard-drive in the PC (This worked fine)
I then booted in safe mode and everything works fine. This first led me to believe that it is a software issue, and some driver/service is causing the problem. I then put the hard-drive in another PC and it worked fine.
I decided that I would just format the drive and install a fresh copy of Windows, the problem is that when it gets to 'Expanding Windows Files' the same thing happens.
Why would it work in safe mode but not normally?, and I'm really unsure what piece of hardware is causing the issue.
Any help would be much appreciated,
Thanks.
