Hi, I've seen several posts regarding some of the various stop erros: IRQL_NOT_LESS_OR_EQUAL BAD_POOL_ERROR PAGE_FAULT_IN_NONPAGED_AREA PFN_LIST_CORRUPT I just started getting these on my Dell XP Laptop. I haven't recently installed any new drivers and/or software, hardware. The laptop was working fine then I woke up in the morning (after leaving it on all night) with the IRQL stop error. I rebooted the laptop and got the Bad Pool error. Rebooted again and got the next error. I've not done any sort of technical work on a laptop before so I'm not sure what to do. The other posts mention replacing the fan and memory but I wouldn't know the first thing about doing that in a laptop. It also has been mentioned to start in safe mode. Is this something that I can fix on my own with proper research or should I just give up and try to find someone to repair it? Will I lose everything that is on the hard drive? I haven't backed it up before, so that's my bad. Appreciate any advice or direction. Thanks.
