Hey I just installed a MSI R9 290x Gaming 4g card into my system.The problem is when I am gaming my computer will restarts randomly in the middle of playing. This doesn't happen all the time when playing just now and then. But when it restarts I don't get a signal to my screen. I had it on a safe overclock rate of 1060mhz that comes pre-set up for it but just to be safe I dropped it to 1030. So what am I missing here is the memory on the card bad? or what? please help...
