PC auto shutdown randomly!!!!

Hi guys..

my PC auto shutdowns randomly..not sure why this is so..

the shutdown/restart prompt (when u do it manually) suddenly appears and next thing I know, the PC shuts down.

dont think its a heat issue as it is an aircon environment. virus scan doesn't help either

can anyone help???

right click desktop > create shortcut
Type: shutdown -a

Whenever the prompt comes up, quickly click the shortcut to abort the shutdown. If successful, there is a program that is causing ur com to shutdown after a certain period of time
