can a bad gpu kill a new system?

[newsystem killer]

I built a new system. I7 4790, msi z97s sli plus. I added an old gpu 550ti and it stared running fine except the graphics card fan stopped working. I changed the gpu to the 9600gtx and it ran for 5 seconds and all went out. I took out the gpu and restarted and it worked. I added the 550ti again and the computer does not start again either with or without a gpU. Did I kill the components somehow?

Please post your full spec.

They're both ~100W TDP GPUs..... could be a PSU issue, but I would expect even most junk PSUs to run those (maybe not overly stable, but at least booting into the OS)/.

Does it work with the integrated Intel HD Graphics 4600 on the Intel Core i7-4790?

Hi, no nothing powers up now. I tried another working psu and it did not start either not even the case fan I connected. Its driving me nuts lol. I was just testing the system before my new graphics card arrives by using my old cards. It was going well until the 9600gt shut it down.

Take out the motherboard CMOS battery for a minute, put it again, check ALL the connections (most critical are the 4/8 pin CPU power and the 20+4 motherboard supply). if you have doubts with your PSU unplug everything but the AC chord, and put a jumper wire between a green cable on the 20+4 connector and a black cable, the fan on the PSU should start.

I will try that ty! I noticed something with the 20+4 pin power conn. One of the silver sleeve tubes inside each of the nodes is misding. Is that normal?
All 24 pins on the motherboard are present though.

Thank you so much everyone. Knowing that you were looking out there thinking of a solution just kept me going with a complete rebuild and it worked. Took the battery out for a while and compketely reseated and cabled everything again. Ni ni everyone and thank you.
