The guy that looked at my tower told me the motherboard took a permanent leave of absence....AND:To replace it,and some other hardware it would need because the stuff is obsolete:Im lookin at around $400.00-NATURALLY:The 3 year warranty expired last August.I ve been thinking about up-grading the memory in the old tower-GOOD thing I didnt-it woulda been all for naught....Ive been seeing these DELL packages with a flat-panel monitor for around$4-500.00.SO:Im goin to Port Huron this Satyrday-Gonna check out Best Buy,I guess....
