I have a problem that has lasted for a while now. I built a computer around May 20th, and installed the drivers for it a couple days later. It seems that when I went to the BIOS and changed the boot priority to the DVD drive (when I was installing Windows 7), this problem started happening. I changed the priority back to the hard drive once Windows was installed, and everything worked fine for a couple days...
Since installation of Windows 7 and the drivers, when I press the power button on the front of my PC, the fans spin up, the LEDs all light up, and the computer sounds like it's running normally. But then, it makes a clicking sound (just one click) and turns off. About 3 seconds after that, it turns itself back on, fans and LEDs and all, and starts booting. (Sometimes, it will reset a second time before starting to boot.) My screen remains blank the whole time, and the computer does not start loading or showing anything until that final reset.
OS - Windows 7 64-bit
Mobo - ASUS P8P67 Pro (Rev 3.1)
CPU - Intel i5 2500k @ 3.3 GHz
GPU - XFX Radeon HD 5770 1GB DDR5
RAM - 2x 4GB Corsair XMS3 DDR3-1600
HDD 1 - Seagate Barracuda 1TB @ 7200 (partitioned to 250 and 681 with the smaller being my boot drive)
HDD 2 - Western Digital Caviar Black 750GB @ 7200
(and what my DVD-RW drive is, I'm not sure exactly.)
I have a 700-watt power supply, so that doesn't seem to be the culprit. However, when first installing Windows 7, I was using a different power supply, and it worked fine. Powering on was a simple, one-click boot. But now, I have another power supply, and this problem persists. I do not know if it is related to the PSU, but it's frustrating me because I know this shouldn't be happening. If I remember correctly, it actually started doing this as soon as I got done changing some settings in the BIOS with the boot priority and the power settings (Power Saving vs High Performance). My current settings are HDD1 Boot Priority, and High Performance (versus Balanced and Power Saving).
So, is this problem really so much of a problem? And if it is, is it possible to fix without a complete re-installation?
