|Ok, I built my pc a couple of years ago. Just recently my pc would not shut down. If I select shutdown through the O/S it would restart and if I hold down the power button it will restart (power button is set to soft-off in bios) I made sure all of the wake-on options are disabled in the bios. I thought it might be a bad power switch so I switched the power button wire and the reset button wire to see if that would fix the problem. Other than the restarting instead of shut down it ran fine. After switching the wires, now the pc turns on when I switch the master power switch on the back of the pc to On without pressing the power button and the pc will not boot up, everything comes on, the fans, lights, hard drive but it wont't even get to the post screen. It's as if it's revving up and down and then when it finally gets to the point that the monitor should click on it seems to lose power for a second and then starts up again. It still does this after I switched the wires back to where they are supposed to go.|
I have an Asus A7N8X2.0 Deluxe Motherboard
1GB Ram (2X512MB Duel Channel)
80 Gig Hard drive
Radeon X 800XL Video card
Antec Smart Power 2.0 500watt Power supply
I used to have an Antec 430watt power supply that lasted about 1.5 years. When that died I upgraded to the 500watt power supply, this one is only 6 months old. I have 5 case fans (2 front, 2 back, one in door. My CPU is an AMD XP2500 overclocked to an XP3200. I can't believe this would be too much for this power supply.
I just wanted some feedback before I go and drop another $100 on my third power supply. If that's the problem any suggestions on a better brand of power supply or if u think it is the power switch I would appreciate. Thanks.
P.S. I tired unplugging the video card and case fans and cd drives, turned on pc and still same problem.
