Ok, a few days ago, I came home to find my computer simply frozen. Moving the mouse didn't do anything, as didn't any keystrokes. I turned the computer off and back on, thinking it was just a small glitch, but when it came back on, the visualization on the screen was funky, really funky. I was able to open programs, but not able to see what to do on them or to even close them. I could not see anything like the red x to close and whatnot. After turning the computer on and off a few times, the monitor was telling me occasionally that the freq was out of range, or simply go to my motherboard's screen that it opens with, which is a white and orange screen that says GIGABYTE. Mostly, it was just a blank screen, like it put itself into standby, even though my settings are not for it to do so. Then I noticed my CPU fan was not running, but all three case fans were. The copper around my Zalman fan was on the hot side. Also, no LED's on my keyboard were coming on. I verified the keyboard's ability to work on another computer, and it does, wih the lights working, as well.

I just built this computer about 2 months ago, and everything had been working fine for the most part. The only thing of note was my wireless keyboard/mouse was not working for a little bit, but everything was fine when I put in the wired kb/mouse.

Oh, I pulled out both internal hard drives and put them in external cases to verify on other computers. Of the two, the 120GB IDE hard drive is listed as the D: drive, but has the OS, which is XP home. On another computer, it said that it was only about 31GB or so and unformatted. The SATA 320GB drive was perfectly fine, which on the main computer from which it was pulled was the C: drive.

So, if anyone has any idea of what is going on with my system, please let me know. If it matters any, the processor is an AMD Athlon dual-core. The Power Supply is made by CLIO, and I believe it's 400W. All components in the system are brand new when assembled, with the exception of the 120GB IDE hard drive that contains the OS.

Did you use thermal compound on the heatsink? Remove the heatsink, clean off the compound and inspect the CPU. Look for discoloration or scorch marks.
Unplug it and remove the 24pin motherboard connector, and plug it back in. Short the green wire with any black wir. in the plug e with a paper clip or whatever. the power supply should turn on and remain on. Buy or borrow a voltmeter and check all of the different voltages in the plug
