Wonder if any of you computer whiz kids have come accross this,my machines keeps switching itself off when I try to reboot I sometimes get a black screen with debug error and a bunch of ffff's.
Its doing my flipping head in .
Its not the ram or video card as Ive tried changing them.
Any ideas would be greatly appreciated,before I go completely barking mad
Cheers,
Bob

Does it run in safe mode? It might be a windows or driver thing not hardware. Save what you can and try a clean install of everything.

XP Pete I havent loaded anything new into the machine at all so its really got me beat.It'll run OK for a bit then wham,its gone.

I had a similar problem. A box came up saying Shutdown was initiated by NT AUTHORITY/SYSTEM. If this is what you are experiancing try this link.
