here is the deal..My friend and I built a new system..Asus A7V mobo, 1.2 T-bird, 256 stick "o" mem, SB live, And a Radeon 64mb ddr vid card, we got it up and running, and the thing kicked *** for about a 1/2 hr, then we shut it down, and upon restart....ABSOLUTELY nothing....Black screen, we played and played and played around w/it to no avail. So then I tried my T-bird 900 in it and still nothing, so I then proceeded to reinstall MY 900 back in my system, and well guess what..NOTHING, what the F*** is going on?, did we mysteriously "fry" his 1.2 T-bird, and my 900?, we both have Asus A7V mobo's, bothe have 256 meg "o" mem, I tried his 1.2 Tbird in my system, and NOTHING, we've tried "swapping" parts from each other's Machines, and nothing, any ideas????????????????????????????????Please help us....
