3-year old home build, Gigabyte 8I915P Duo Pro Motherboard, P4 3.0GHz, = 2GB DDR RAM (abt. 1 to 1-1/2 years old), Antec 430 Watt True Power 2.0 = PSU (2 years old), Windows XP Home, no errors in Device Manager. I have = not added any peripherals or taken any out in a long time. =20 About 3 weeks ago I started having problems with my computer not wanting = to turn on at all. I've been having to press the Power button over and = over, feeling around each side to see what the sweet spot of the day = might be, dreading that today would be the day it wouldn't turn on at = all. I cleaned it out, reseated everything, no change. After you press = it over and over, it'll come on and run fine. It's not unstable, not = overheating, temps are the same as always, and it's not rebooting = itself. It runs fine until I turn it off for the night. I thought = surely it must be the case power switch. Everything, including front = panel, is attached to the front bezel/face plate. Hubby is = electronically/mechanically inclined and he looked at it, found one = broken off out of two naked wires coming off the switch into a small = white box that has wires that plug into the HD line to make the light = blink when there's HD activity. He clipped the other naked wire to the = same length and shoved them back in the white box and we thought that = was surely it - NOT! I pulled the switch wires off the motherboard to = check for dust or loose connections, no change. Hubby also thought it = was the switch, so I bought another case and transferred everything into = it, and it's still doing the same thing. Now I really like my new case = and I don't regret buying it, but that's not the problem. I've reseated the RAM, tried it with just one stick, swapped out the = current RAM for the sticks of 512MB Corsair that I upgraded from - no = change. I unplugged all the drives - no change. I thought maybe one of = my optical drives was causing a problem, so I unplugged them one at a = time, and plugged them back in one at a time - no change. A few times = we saw the rear fan give a slight jerk when we pressed the power button, = but it didn't come on. I have a brand new LCD power supply tester and = the Antec PSU test numbers are below. The PSU plugs into the MB with a = 4-pin 12v connector, which I also plugged into the tester. +5v: 5.2 +12v1: 12.1 +3.3v: 3.3 -12v: 11.9 +12v2: 12.0 5vSB: 5.2 PG: 350MS Here's what Speed Fan shows: Vcore1: 1.31V Vcore2: 2.56V +3.3V: 3.23V +5V: 4.97V +12V: 11.84V -12V: -8.91V -5V: -7.72V +5V: 6.85V Vbat: 3.18V So, what else should I be looking at here? Motherboard? CPU? Is it = possible to have a circuitry problem on the MB where the Power Switch = plugs in? I've taken in a couple of computers that had motherboard or = CPU problems, but they were always unstable and never acted like this. I'm tired of thinking about it and I need some fresh input.
