I went to wake up my desktop up from sleep mode the other day and the monitors wouldn't come on so I hit the power button and restarted. After choosing normal mode on reboot, it showed the microsoft bar then flashed to a blue screen and restarted. I then tried safe mode and last know good conifguration and say reaction. So I followed the instructions and tried to boot off the dvd and after the load bar completed it went to a blue screen and stayed, At the top it said "IRQL_NOT_LESS_OR_EQUAL". What do I do to fix. I have not installed any new harware since I built the computer.
