Since yesterday my PC has become somewhat unstable often shutting freezing or just powering down. This seems to be when I am performing more heavy duty tasks such as video conversion or burning a DVD. Light duty tasks such as browsing doesnt seem to be a problem.
As I said, video conversion seems to set it off so here is an example of what happens.
Occasionally it will not pass POST, PC powers up, fans start whirring but then I get BIOS error beeps that I have been unable to diagnose. My BIOS is Phoenix and I think the version is v5.17
The beep is a single beep about 1 second long with a 1 second pause followed by a 3 second continuous beep, then a pause then the pattern repeats.
(posting now before PC freezes)
If this happens, I power down and unplug the power lead , leave it for five minutes and try again.
Then it might work or it might beep again.
When it does work it boots up OK and like now I can perform light duty tasks but I am sure if I were to run a more demanding app I would have problems. I have tried running AV and ASW programmes but they seem to again cause the PC to freeze.
In case it was an XP problem I tried to do a repair install but that froze as well.
Anyway, I am at a loss here so any help would be greatly appreciated folks!
