Ok so I bought a secondhand 3 week old MSI 4890 OC for my GFs pc. Now I have been battling with it for the last hour or so. The installation only took about 10 min and was super easy. Now when I start the pc up everything runs fine and it goes into window for 2-3 minutes and then BSOD and restarts. I have tried to reseat it and used different power cables for the card...? Any suggestions for a possible solutions?
