I originally had an asus R7 250x that stopped working with my PC and it would not boot/display. Pressing the power button would yield no result. It worked fine for 3+ months before giving me this problem. I had a friend with a 500w PSU and he let me have it. I installed it and instead of not booting, the power led would light up, but my mouse would blink red once and then go out. The GPU should work fine with a 400w PSU but was giving me problems with this 500w. I gave up and bought a GTX 560 Ti. Stuck it in, PC worked fine, installed drivers etc. That was yesterday. Today I needed to do something that required me shutting down my PC and upon doing so, it would not turn back on. Gave me the power led on/mouse blinking red once then going out problem with no display. Before going and buying a bigger PSU I wanna make sure its not power that's the problem. I would very much like to fix this up without having to buy anything.
