I recently upgraded my motherboard to a Gigabyte GA-880GA-UD3H AMD 880G AM3 Motherboard, Processor to AMD Athlon II, and 4gb of ram. Whenever I start up my computer I cannot get it past the windows loading screen, it pops up for a second, then BSOD restart. I run windows XP. When I switched motherboards (the first time before that one blew out) it was having this same problem. Then when I was forced to make this upgrade the problem continued. The only parts that are the same are: Power Supply, PCI-E video card (taken from my brothers out of commission computer), and the HDD. I've pretty much ruled out the HDD since I've tried 4 different ones, and had similar results. Did I connect something wrong? I'm so confused. If I could have some help, that would be great. Much appreciated.
