PC auto shutdown

  Hi all. My PC got problem (again).

  Recently my Graphics Card got problem so I asked my friend to change it for me (from 64MB into 32MB T.T).

  Now quite frequently, my PC will automatically shut down whenever I'm using it. Not reboot but total shutdown.

  If I try on-ing it, the fan will run for a few seconds then everything will stop. No sound, not starting up.

  I have to wait for a while (a few minutes) first before trying to on it then will be start to boot up.

  The auto shutdown happens ONLY when I'm USING the PC. Sometimes after a few hours of using, sometimes after minutes of using. If I leave it overnight to download stuff or just listening to the music, it won't/hasn't happen.

  Sometimes when I start my PC, there will be a message saying something like "Windows not found. Please insert start up disk" (not very clear about the message). I have to restart my PC a few times before it can start up normally.

  Help? T.T

  Backup your data 1st, then clean your PC internals of dust and check whether your CPU fan is rotating smoothly. If problem still occurs after that, try the suggestions below: Run harddisk diagnostic utility to check for harddisk errors ( google for "seatools" from seagate ) Run ram checking utility to check your memory for problems ( google for "memtest" ) If nothing comes up from the above tests, format your harddisk and re-install windows. As what natural_boy says too many possiblities for your PC problem

  I've got 2 hard disk. One for my OS and the other for al my other datas.

  I tried the seatools but it can't complete the scan for the data harddisk. no problem for my OS harddisk though.

  Cuz if it's troublesome (i lazy lah...) I might as well change a new pc. i've got a 15"lcd monitor (can lah... mai hiam lah...) then I'm not a gaming person so I can just get a "normal" pc just to do surfing and normal usage only. Only thing that's stopping me now is Vista... :/

  System unstable... graphic card most probably not supported.
