So I've been getting bluescreens for few days now and today I've had something like 4-6 bluescreens. I have pretty much tried anything from memtests to disabling sound drivers to changing cpu. So far nothing has fixed the problem. Bluescreens occur on random times, sometimes when I'm just surfing in the internet and sometimes when I'm playing something. Most common error message I've had is IRQL_NOT_LESS_OR_EQUAL. Any ideas to fix the problem? Oh, and only critical error in Event Viewer is Kernel-Power (41) Specs: AMD Athlon II X4 620 Ati Radeon 5850 6gb ddr 3 Asus M4A77TD Pro Windows 7 Home Premium 64-bit.
