A couple of days ago, my computer crashed on me while I was working in Photoshop. Gave me a blue screen and some stop error. At the time, I believe the file I was working on basically ate up all the free space on my OS drive (swap file). After letting it sit for a day it booted up fine and has been up for about 4 days. It booted up and had about 4mb's free, I had to go in and delete the temporary files to free up my OS drive.

Today, while surfing the web, it just froze and shut down on me. Now whenever I try to boot it up, there's melody/tone (It's an endless loop of a high pitch, low pitch, high pitch, low pitch... dahn DAHN dahn DAHN dahn DAHN...) that plays and I don't see the cpu or mobo fan spinning at all. All the lights I have on the front of the case, the CD-ROM light, HDD light, and Power light come on and stay on. The NIC light in the case stays on, the case fans and video card fans spin. However, the mobo fan and CPU fan don't spin up at all. There is no video signal and no HDD action to signify that it is indeed booting up.

I tried taking out sticks of ram and moving them around, but that hasn't solved anything. Before the first crash, I didn't make any significant hardware changes (... actually no hardware changes I can think of) since I replaced the motherboard (dead MSI K7T Pro2a to the current ASUS A7V133).

I can't seem to find the meaning behind the melody/tone on the ASUS website and I don't have the manual with me, I dled the pdf manual and I can't seem to find it there. Any ideas? Thanks!

UPDATE: I tried a friend's CPU, no luck. I took out the CMOS battery, waited for about a minute, placed it back in, put back my original chip, still nothing. I found another... sort of power pin on the motherboard above the RAM slots, where you connect the CPU fan power cord, I connected it to that instead of the one by the CPU, when I booted up, both fans (mobo and CPU) turned on for a second before it stopped spinning again.

Any ideas? http://www.electrocution.com/beep.htm#AWARD

1. Your computer plays music at startup.

Beethoven's "Für Elise" and Disney's "It's a Small, Small World" are pleasant tunes. If you hear either of these melodies when you turn on your computer, you're likely to want to relax or sing along. (After all, a computer that has developed a taste for punk rock music would be hard to handle.) Or you may suspect you have a virus.

Wrong on both counts.

The computer is telling you that the microprocessor or microprocessor fan is failing, or has already gone south. Or it may be telling you that power supply voltages are drifting out of tolerance, or that the supply cannot meet demand.


The music is a feature built into the Basic Input/Output System (BIOS) of some motherboards. It is a gentle reminder that you have a serious problem. It's probably not a problem if you hear a couple notes at boot-up. But if you regularly hear a tune, you need to take care of it.

What can you do? In all cases, you can get by at a reasonable cost if you have the ability and time to diagnose and fix the problem. You might well decide to take it to a shop. If so, you're probably looking at a minimum $200 repair. Labor is expensive. (If you decide you really do need a tech consultant for support, check out Microsoft bCentral's small-business consultant directory to find one near you.)

Can you ignore the problem? Not for long. Heat is the enemy of computers. It will fail soon, although perhaps you enjoy listening to "Für Elise."

Consider looking at new computers. The problem with fixing an older computer (especially if the bill is high) is this: It's probably just the beginning. Over the years I've had problems with memory, hard drives, floppy drives and CD drives. Something else is going to break. Speaking of which . . .

if the fans start up and then stop imediately, check the switch on the power supply is set for the correct voltage, 115V i belive for the US

Do you happen to have a 3 to 4 pin adapter laying around to hook the cpu fan into to see if that will work?

Well, overloading that connector, obvoiusly. You must have either had too much connected to that mobo, or else something shorted out (fan, cpu........, likely a fan though)
