BSoD occurs with graphics cards

[tdsilk]

Hello,

I'm new this forum, and need help troubleshooting blue screen issues. My system specs are:

- HP Pavilion a6700y
- AMD Phenom Quad Core 9150e 1.8GHz processor,
- 8GB of DDR2-800 memory, and a 500GB hard drive.
- nVidia GeForce 6150SE Integrated
- 550w PSU

The machine came with 4gbs of ram and I upgraded to 8. I also added a couple of internal hard drives.

Now for the problem. When I use the integrated graphics everything runs fine. However, i've experienced BSoD with two different graphics cards (HD 5670 775M 1GB DDR5 DP HDMI DVI PCI-E and GTX 560 ti). when the problem occured w/ the 5670 I had to reseat the card to get it to work. However, it eventually gave me the BS again. I thought it was a bad card, but as of last night I installed the GTX 560 ti and the BSod appeared again. I could be wrong, but my guess is it's not the cards and something with the system? I'm currently running "memtest 86" and the first pass was successful. I will have to see what the other passes reveal. Any ideas what else I should check?

Thanks,
Troy

hmmm. Now replies on this. Btw, my memtest ran w/o errors. Guess I will check the bios next.
