About a week back I was at my PC reading the news and playing Football Manager. Then for no reason my PC seemed to shut down and the monitor went into stand by. I thought I had somehow lost power but the PC was still running, the front LED was still on and the internal fans where still on.
I turned the PC off and tried to start it up as normal but I only got a partial start up. DVD/CD and CDR drives would spin up as normal but then stop and no response from monitor or keyboard/mouse.
I tried a couple of things myself, opened up the case and checked all the wiring and connections, replaced the mother board battery and dusted. No change (At this point I was thinking PSU/MOBO/HD problem). Randomly I tried a DVD but nothing happened so I took it out and to my surprise the PC restarted and booted up as normal.
I started using my PC as normal and tested out all the programs I could think of and did Virus/Ad ware scans which found nothing. So I gave Football Manager another go and my PC dropped dead with all the same problem as before. Again, I tried a DVD and the PC rebooted.
So this time I made an effort to crash the PC by starting up Football Manager I played around for a good 3-4 hours and then the PC crashed, I put a DVD in got no response.
Frustrated I just left my PC on and about an hour later it started up completely at random without me doing anything. So what can it be? It sounds like a hardware problem to me but why does it only happen when I'm playing Football Manager?
