Right, so I'll start at the beginning... I got a new gpu. MSI R9 290 4GB Gaming OC edition, and a new psu, Coolermaster G750M 750w, for christmas. I installed them correctly on christmas morning and got it up and running absolutely fine. It ran for about 4 hours, and then all of a sudden my screen went all black, and my PC reebooted; I thought it had just overheated, but it hadn't, the temperatures were all fine. And ever since then, my PC now randomly reebots whenever I have the 290 in. Here are my current PC specs:
ASUS M5a78l-m/ USB 3 mobo
AMD fx 6300 cpu
8GB generic ddr3 ram (i think)
1tb HDD
MSI r9 290 (new)
Coolermaster 750w psu (new)
I tried putting my old gpu back in, ASUS GTX 650, and my pc runs fine, so it can't be the new psu. I've uninstalled all drivers for AMD and Nvidia and still doesnt help, i've enabled force constant voltage with msi afterburner, I've updated my bios, and ive put my old 430w psu back in to power the system, and used just the 750w psu to power only the gpu... After all that I decided to return the card, however they came back to me and said that they couldn't find any fault with the card? I really don't think they tested it properly... However, like right now, i just received it back so i put it back in, still blackscreens, but i left it on the desktop for ages, surfed the web, wrote this, and it hasn't blackscreened at all? It has blackscreened before when I was just surfing the web and on the desktop? Please can someone help me, I honestly don't know what else to do... Thank you so much for reading!
