yeah i know its older but i've got 4 gb ram, the 4800+ toledo cpu, running vista 64, got a corsair 750 psu w/ 62 amps on the 12v rail. i thought that i could at least be able to upgrade and get by for a while before i built a new system. running a 7900 gt card now, had an 8800 sli set-up before, thats why i cant figure out WHY it wont post now.
