Help with my CPU, MOBO and PCI-E

[kaspro]

Hello everyone, i had these two old posts here

http://www.tomshardware.com/answers/id-3280331/restart-changing-cpu-fan.html
http://www.tomshardware.com/answers/id-3301004/pci-stopped-working.html

and this's my third one which completes the problem, it all started when i got a new GPU (RX 480) and PSU (Corsair CS550M (GOLD)) for my System (Core i7-4790, ASUS H97 Pro Gamer)

Later i decided to change my cpu stock cooler to a Cryorig mini one coz i wasn't gonna overclock anything, and then my computer started to do some random restarts and then GPU stopped working, i changed the cooler to the stock and still the same, changed PSU, GPU same problem later i got a used motherboard and everything worked fine

There was only one problem with the built-in Realteck HD Audio which was too low so i got a new Creative Sound Card

After a week the sound card stopped working i tried some driver updates but still nothing, i changed the sound card to another PCI-E and it worked, but when i tried to move it to PCI-E X16, the system did not boot and it now it's very close to the GPU

But my problem i really wanna know what's wrong with my computer cos it seems PCI-Es are failing and I don't know if my CPU is ruined or is it the PSU or the RX-480 are destroying my system

Please help me find what's the problem cos i feel the PCI-E i'm using now gonna stop after a while

These all sound like driver stability issues, have you formatted your drive and done a fresh install of windows with drivers?

I tried with my old MOBO and it didn't work, and now the sound card works fine with the other PCI-E and when i try the original PCI-E it won't work at all!!!

It seems you were right, i tried to re install Windows and everything was going fine until i tried to install AMD Chrimson after Creative Driver and everything collapsed, so i re installed windows again and this time i kept the original driver provided by Windows which is actually provided by Creative and it's working fine, Thank you
