I think I have some kind of virus on my pc. After about 20-30 mins of my pc being on I get a blue screen which says: "A problem has been detected and windows has been shut down to prevent damage to your computer. DRIVER_IRQL_NOT_LESS_OR_EQUAL" then there is a whole page of info about it. does anyone know what this is or why it is occring? im guessing its a virus. i've ran a scan but anything found is quarantined or deleted but this still occurs. I tried a system restore and that never worked either. any help appreciated.
