This is the default behavior when Windows XP encounters a system failure.To see what the error was you can change the default behavior by right clicking on “My Computer” and choosing “Properties”.I have had this PC for a little over 2 years and although I have had tiny problems here and there, nothing this troublesome.

Hey Everyone, Long time observer, first time poster here at tom's hardware.

Roughly a week ago I made the upgrade to Windows 8 Pro (from win7 premium) due to the deal Microsoft had running for updates.

i) The errors I have noticed are: IRQL_NOT_LESS_OR_EQUAL, DPC_WATCHDOG_VIOLATION, PAGE_FAULT_IN_NON_PAGED_Area. Sometimes my displays (3 monitors) just shut off and the power buttons start blinking as if they are not getting a signal from the tower; this is also true for both my keyboard and mouse (they are both illuminated/back lit), as their lights go out.3. I can see everything, but my mouse won't move, keyboard won't do anything, etc.
