I know, compaq.... Right now I have a 2.5 celeron, two 256, pc2700 and one 2100, I know... I have a ati 9250 pci, and Trigem Imperial-gv socket 478 motherboard. I know It's the mobo, checked everything, I was thinking about geting the same mobo on ebay Mobo But I was wondering, can I get a cheeper one that is compatble with my system? I haven't really done work with a mobo before. Anything would help, thanks. BTW, the compaq I have is a x5000nx.
