reciently i,ve been building pcs from junk: messing around with old stuff till my new parts get here. the pc build is mombo :jetway pa78vm3 cpu amd semperon 3ghz single core vidcard : zotac nvida geforce 8500gt 1gb pci-e ram: avant ddr2 800mghz 2gb x2 250gb hdd windows xp prof. 450 watt psu. heres the weird part. the day i fired it up? it worked fine, loaded windows ? error on the load :wtf? bluescreen/ memory error: wtf? shortened the ram to 2gb & tried again. this time it worked better. still it would crapout on me , or just won,t turn on so i shut it down for a while, & set it aside to get my other unit put together & so 1 built another exact except the cpu was a amd phenom x4 1.7ghz quad core. this one is a dream, loaded xp fast , tried vista , perfect, ubuntu ? ran 10+ diffrent games everything flawlessly. so i went back to the problum unit switched parte from 1 to another , i know its not the parts ram hdd vidcard or the os. it leaves 1 option the major question is ? is it the cpu,? or is it the board or psu?
Your motherboard must be causing problems. Not compatibility. Did you attached the additional power connector for video card?
yeah it,s connected. could it be the psu? it,s onlt 350 watt , while the other unit(the woirking unit ) is 480 watt. would that be the prob? underpowered? if that is what is the prob. then it is as easy as getting another psu . right?
