PC shutting down???

  Winxx 12:51 01 Apr 2007

My pc just shuts down randomly with no warning or close down boxes, the screen just goes blank and power goes off, this usually happens on a particular site i use and then any other site i use after that. Any ideas please?

Random shutting down is - overheat - faulty PSU - virus / spyware

Scan for virus and spyware

Heavy use of CPU - check temperatures click here

PSU starting to fail - check voltages

I have an xp1800 which gave the above symptoms and it turned out to be dust and muck blocking the heat sink under the fan on the cpu. I used a compressed air spray to remove the muck and have not had it shut down since.
