PC switched itself off and now will not re-start windows. Gets as far as the windows XP logo but then switches off and starts the boot process again.
Just before it failed there was an error message saying 'process or thread unexpectedly exited or has been terminated, restart your computer' the file it was referring to was windowsroot/system32/ntoskrn
Won't let me start in safe mode either but i disabled the auto re-boot option and get the blue screen with a message stating:
The technical Info is 0x000000ed (0x86f42bf0, 0xc0000006, 0x00000000, 0x00000000)
I ran chkdsk /r using my windows disc but it has not resolved it.
