PC keeps switching off !!

[paulbuck]

Have you tried running an anti virus in safe mode

the anti virus i have on wont run in safe mode , when i click on it nothing happens !!!

Try reinstalling windows first mate, if its running ok in safe mode would sometimes mean the power supply is ok but it all depends.

But....Normally as a user said above, when a pc is shutting down randomly it could well be the psu, I would first try a reinstall of windows to rule out anything to do with windows and drivers etc, after that if it does keep shutting down in normal mode then I would suspect the psu, its very difficult to tell though, try the reinstall of windows first and then we can move on from there, thats what I would do and Ive had loads of experience of many of these issues, its hard to narrow it down but you have to start somewhere.

if your afraid windows is doing it. Try installing a fresh copy of Ubuntu and see if every thing is alright..

I think it's not possible windows doing it self...install ubuntu...??? for who now how to use it no matter but for whom familiar to windows....it's difficult...must learn it again

D21198071 is right. Installing and using ubuntu for someone inexperienced can be a pain in the butt so it is not recommended. What you could try though is dl ubuntu and use it as a live cd and see if same thing happens. But I still don't recommend it. What I DO recommend is download a win mini pe from somewhere. Practically it's a live installation of winxp that runs from a cd and has a dosen useful apps pre installed (like anti-virus, partition managers, etc.).
