Hi, i just bought a new case (Cooler Master HAF XB) and i reinstalled my pc (no new parts) in it. My Evga GTX 770 SC isn't detected (not even in the device manager) so I have to run on onboard graphics. Whenever my 770 is plugged in I eventually get a bsod.

What I tried:
-Taking my mobo's battery out and put it back in
-Swept all my graphics drivers (with driver sweeper because it wouldn't let me do it in programs and features)
-Checked 10 times all my cables and connections
-took out my wifi and sound cards
-Tried with my old gtx 570 which is detected and runs on basic drivers but I get a bsod pretty fast whatever pci-e slot I put it in
-When i put my 770 in my second pci-e slot it was detected but it stayed on bios screen and i couldn't get into the bios, but now I think it's just not recognized anymore.
-Updated the bios and changed the settings to optimized defaults but still no change.

Specs:
CPU: i5 2500k
Mobo: Asus p8z68 v-pro/gen3
PSU: XFX pro 1000w full modular (changed recently)
Ram: 2x4gb corsair vengeance + 2x4gb gskills ripjaws

Edit: I get bsods even when my gpu is unplugged...

It could be the motherboard, but I would also test your DDR3 memory: www.memtest.org

1) Make sure your RAM is fully seated and installed in the proper slots (your MOTHERBOARD MANUAL will specify). I guess you probably know which slots worked before though.

2) Enter the motherboard BIOS and make sure the CPU and Memory are at default, stock settings. Just click "XMP" if it's there, verify and save.

3) Boot to the Memtest disc or USB drive and run a full loop (about 30min per 8GB) or until errors show.

4) If ERRORS OCCUR, then install only ONE module (see motherboard manual for placement of one module only) and test each stick separately.

5) If you find a stick that passes then boot to Windows and see if it works (then RMA the...

*If memory PASSES Memtest then I'd also lean towards the Motherboard as the bad part likely though the Power Supply might also be problematic.

In ORDER of what I think might be defective from most likely to least:
a) DDR3 memory
b) Motherboard
c) Power Supply (yours has lots of power but you mention changing to it RECENTLY which concerns me. If Memtest passes I recommend trying a different Power Supply if possible. Almost anything should work for basic use with no graphics card.)

This sounds like a RAM issue to me as well. As photonboy said, try reseating and run memtest. Power supply would be number 2 on my list however, it could even be a faulty power cable from the PSU.
