I have had several issues with my computer from ATI card crashes to sound popping with a headset.
After months of looking trying everything i came across DPC checker. Just today I have solved my sound pops using DPC checker, peaked at 4000 every 1 - 3 seconds. I found the program that was causing it and it was GUI.exe looked it up i got both responses as harmless and dangerous. but that's not why i am here. but if you feel you should add something about this annoying program please do. Could a potentially high and well timed dpc spike cause any device to crash? could this be why my ATI card drivers crap out?
