Im not sure if this is the PSU. Checked HDD. Checked Windows. And i doubt its the RAM. It usually hangs if you try to load applications/games directly after startup. I currently Have a CiT 600W PSU (bad choice im guessing) Heres the stats for Voltages/temps (idle) http://i91.photobucket.com/albums/k294/frcraig/Capture.png Now im not sure or are the 5 & 12V supposed to be that low. I should also mention that once it does load and has been on a while it will work continuously.
