I've started having problems keeping my computer running. Sometimes while on the internet or playing games - doesn't really seem to matter,I get either booted back to the desktop or the computer reboots and then says windows has recovered from a serious error. When it gives me a link to the Microsoft Crash Analysis site it almost always says an unknown driver caused the problem. Just recently it said there was a CPU hardware error. I've updated video, audio, and board drivers but it's still the same. There does look like there has been some swelling of the capacitors around the CPU, but most times everything works fine. This system is about 3 years, old from the time I purchased it refurbished from Tiger Direct, so yes it is out of warranty. The main problem I have with replacing the motherboard is not the task itself but having the XP reinstall disks that came with my computer not recognize the new motherboard as the same system. I've looked around a little at some replacements but have become more confused than anything else. Would replacing this board solve anything or should I look elsewhere for a solution? If I should replace the motherboard should I try to get an identical one and what steps should I take to make sure everything is compatible. David
