Hi all, newbie here with what (to me) is a bizarre problem.
I have an 'Infinity' PC with a Pentium 4 3.2 GHz processor and 1GHz RAM and an ATI Radeon HD 2600 Pro AGP graphics card. I have had the PC for quite a while now, a couple of years probably-and it was second hand, so it's quite old....
And it has been absolutely fine, til maybe 6 weeks ago.
It is perfect, will run all day, surf the net, watch videos, youtube, whatever. Until you try and play games on it.
If I play Flightsim or something, it will function perfectly well, for about 5 minutes, then it either freezes momentarily, or goes straight to, a black screen. The mouse (USB) switches off, the screen goes to standby, but the PC keeps running. The only option is to hold the on/off switch to shut the PC down. And after it does shut down, the keyboard stays live....
This also happens if the kids are playing online games...
I thought it might be a virus, so last week I re-formatted the thing. And it's just the same.
Any ideas most welcome.
Thanks in advance!
