A few weeks ago I started to get multiple problems on my computer. Files corrupting everywhere. I am unable to transfer files without risking a BSOD. I keep getting 3 errors specifically. I get "PAGE_FAULT_IN_NON_PAGED_AREA", I get "BAD_POOL_CALLER", and I get "IRQ_NOT_LESS_OR_EQUAL_TO". I am running Windows XP Home Edition SP2. I think one of the problems might be the video card. I suspect another might be a bad RAM module but I have no way of knowing for sure that I know of. Is there a way to find out what is causing all this?
