For instance, can you access the system BIOS? If it locks up within 5 seconds of turning on, even when booting from disc, it is likely a hardware issue. However, if it locks up 5 seconds into Windows, it is a software issue, likely with a startup application that can be disabled using MSConfig (press Windows + R and enter msconfig into the Run box) in Safe Mode (press F8 during boot).
I have a HP Pavilion PC running windows vista home professional edition (64 bit).
Never had a problem in 4 months sinvce new until today. I was running a video editing programme when the system locked. All attempts since to enter the system have failed.
I re-boot, and for 5 seconds I have access to the computer (while start-up process is completing), as soon as start-up is done the computer locks and I can no nothing but re-boot again.
I have run system self tests om start-up and have no errors.
I CANNOT get access to system restore etc as comupter locks after 5 seconds.
I have tried re-entering the system disk, but never enough time to execute it.
Any suggestions would be very much appreciated.
