The rig in my sig. One day my computer required me to flip the power off and on at the back of the power supply. The computer started not turning on untill I switched power outlets and tryied a combination of pressing the on button, the power supplly and switching power outlets before I could turn the computer on. Now (today) when I turn on the power from the power supply, the whole computer tries to turn on, and I no longer need to press the on button in front of the case. But I cant even POST. My mouse is dead, and my monitor has no communication with computer. Ive swapped power supplies, my Video card should be fine, my mouse doesn't turn on (usb) but the lights and fans work. .... I'm thinking maybe ram or CPU, or MOBO ??? HELP please.
