Hey, I upgraded my graphics visiting-card and PSU today and perpetually since Windows has been a fortune slower - slower starting up and slower in global also. Conduct is think twice in games all the same, which is adept as that's why I bought the graphics card. The light on my lawsuit is ON ALL OCCASIONS blinking and I can ALWAYS hark to the little whirring sounds, both things that acclimated to to once in a while occur when launch a outline or generally when the computer was thinking, but when I check up on my CPU handling it is not extraordinary at all (at 5% upright now). My retention is also no more than condign subservient to half full. I cannot deem what the problem is, I'm unshakable I've done something sinful - here are my specs: Intel Middle 2 Q9400 Asus P5Q-Pro Radeon HD 6950 4GB RAM XFX 850w Windows7 64-bit My shabby specs were the unvarying but with two HD 4850s and a Furor 900w PSU. Thanks Baby Grace x
