I was having issues with my ram. Would run i stick fine, but when i put two in, the comp would freeze at random places. So flashed bios and attemped to tweak ram settings in bios. This still didnt not help me. I shut down the comp and took one of the sticks out, thus leaving a 512 stick; however, in the process i unplugged the heatsink cable that connects to the mobo (was in the way). After i took the one stick out, i pushed power, and the lights, fans, etc. came on but for only split second. I then realized that the heatsink cable was not attached to the mobo. So i connected this back and pushed power, but nothing happened. Now the comp wont turn on at all. *note: the heatsink still came on when i pushed the power button even thou the cable was disconnected (the heatsink gets power from a 4-pin connector). A week ago i bought a 480 Thermaltake Silent Purepower psu, doubt that could be the problem. Any suggestions?
