So a few weeks ago my powersupply burned out... It was a 580 watt and I just replaced it with a 650 watt. Everything is connected fine, everything booted up and things are running smooth. However, I notice certain internet graphics don't load as fast, or at all. My pc also restarts when I try and play half-life 2. Am I wrong in assuming my graphics card isn't receiving enough power or is connected wrong? As far as I know it is receiving adequate power. Where should I go from here? Thanks a lot for your time!
