I decided to upgrade my system with a new GPU and a new PSU. Unfortunalty i've now ended up at the point where my PC wont boot my SDD. I started with the GPU alone but found out quickly that i requiered more power since my PC couldn't find the GPU and both LED lights besides the PCIe power inputs glowed Red. I went ahead and bought myself a new PSU that had the requiered power. After installing the new PSU with all connected cables, it started off booting just like normal.

I went ahead and reinstalled the drivers for the GPU so that I knew it fit the standards, after this my pc worked just fine for a short while. I quickly realized that my PC started having issues and it ran slower and slower. I allso realized that the HDMI output were as far from optimized as it could get. After restarting my PC the Mobo weren't able to read my SDD (where my current OS was) and this is as far as i've come. My main question now is do i have to install my OS again, and download seperate drives since the once i got on the CD wasn't reliable? I have checked the different cables and everything should be where it belongs. Another quick mention is that my old GPU(EVGA gtx 560TI) works.

The specs that i find of important is listed below:

PSU: Corsair CX750M
GPU: ROG R9 290x Matrix Platinum
Mobo: Msi B75MA-P45
CPU: Intell i7 3770

Sorry for my bad explenation and/or word vocabulary.
 


Ok, i have now updated my BIOS and everything seems to be workning except that the HDMI output is not optimized to either of my monitors and the gamma is way off. Could this be a GPU driver failure? When i check what driver i currently use it says "AMD Radeon R9 200 Series" is this the correct driver or should i look for a spererate one matching with my 290x? and thanks for the quick reply!
