I booted up my PC yesterday, spent 20 minutes on the web. My monitor then went into standby like as if the PC was rebooting, but there was no BIOS beep and the video didn't return. Probably loss of sync with the PC. Switch PC off, turn back on, same thing happened but losing sync quicker each time. This got to the point where I only just get enough time to view some of the BIOS settings and then the video goes again.
Tried the following:
- Used RAM sticks separately
- Reseated RAM
- Reseated graphics card
- Unattaching USB peripherals
- Unattaching IDE/S-ATA drives
- Tried DVI cable and VGA cable
- Different monitor
And still the same happens on every attempt. It was 3:30AM so I gave up at that point.
Now it's 7:30AM. I reseated the graphics card two more times and managed to get steady video for more than 20 minutes. Ran the following hardware tests:
- Memtest PASS
- WD hard drive diagnostic PASS
- PC Check (motherboard, CPU, video) all PASS
After all of this, I can't work out what has happened and I'm not sure how consistent this will be. The only abnormal observation is that the CPU runs hot (50ºC). Could it have been that or could it have been a badly seated graphics card? Bear in mind that hot CPU temps normally causes a computer to continually reboot itself, not lose video. Nothing is overclocked. Any help / ideas muchly appreciated
