Big problem.

I had an evga 7600gts for about a month and a half, and it ran great. No problems or anything, and one day it STOPPED sending video. I took it out and WENT back to onboard video, and it worked fine, but no matter what i did the 7600gts wouldn't send any video output. so I rma'd the card for a refund, and decided to go with a sapphire x1900gt.


Today, the sapphire card arrives and I stick it in. I made sure the bios and everything was properly set, but its having the same exact problem as the 7600gts was. Lights come on, but no video output. This time, however, I tried running it with the case open and noticed that my cpu fan was NOT spinning at all. It spins when I use onboard video, but when I try using the x1900 the cpu fan will not spin at all.(even if i'm plugged into onboard video with the x1900 plugged in the cpu fan won't spin).

Usually my pc makes BEEPS when its booting up, but no such beeps when I have the x1900 plugged in, same when i was having the problem with the 7600.


Help...please...... could this be a burnt out pci-e bridge? is there any way to test for that?i went through emachine tech support (gah) and they had me reinstall my chipset drivers, nothing. However, I did NOTICE (not sure if it was doing this before or not) that the CPU fan spins for a couple of seconds before it STOPS. All the other case fans are working, its just the cpu fan that is not, even the graphics card fan is spinning fine.


And here's my specs:

Emachines T6534
AMD athlon 64 3700+ San diego
512mb ram ddr 3200
200gb 7200rpm hdd
Nvidia 6100 integrated graphics


And i've added:
430 watt Antec Trio Truepower psu
1 GB OCZ ddr3200 Ram


All of this works until i try to plug in a sapphire ATI x1900GT.If you can run onboard video and BOTH AGP cards exhibit the same problem, then the looks like the AGP slot took a dump.
