Ok heres the deal......I recently installed an Athlon 64 3200+ (939 pin) cpu on a Gigabyte K8NS-Ultra 939 mobo along with 1 gig of corsairxms ram memory. Everything was great until my FX5700 video card quit. (The fan was locked up so tight you couldnt move it at all and when you tryed it would torque the entire card, so I am pretty sure that card was d-e-d ded). I installed an *emergency use only* heat damaged ti4200 card and that card apparently quit after about 2 weeks.
Now here's the kicker. I got a replacement card from PNY for the one that died but it wont work on my Gigabyte board. (turn on the comp and nothing shows on the monitor.) The monitor is working because I hooked it up to our other comp and it works as advertised. So I tryed a known good video card in my comp and the results were the same, nothing showing on the monitor. (Yes, the monitor is plugged in and the cable is hooked up to the vid card correctly) At this point I suspected a bad AGP slot, so I reinstalled my old motherboard/cpu combo and guess what? I cant get any vid card to work on that board either.
When I turn power on to the system all the fans run and the hard drive runs etc. Is it possible for the power supply to be weak and not providing enough power to power up the vid card? If not, what else could possibly be wrong?
Also, the replacement vid card that PNY sent has some issues on 2 other comps I tryed to install it in. On one comp the monitor shows vertical lines about 1/4 inch wide with multiple colors in the lines that change constantly, the other comp has the same graphics issue but the lines are horizontal and only about 1/8 inch wide. I didnt install the drivers for the card on the other 2 comps since I just wanted to see if the comp would boot up with the card installed. However, I have NEVER seen that graphics issue before with the vanilla VGA drivers from windows.
Any help/suggestions would be greatly appreciated.
*edit* my current power supply is a 400 watt unit, manufacturer unknown at this point unless I uninstall it and look at the side.
