BleepingComputer.com: Computer Shuts Down When Turning On

Well my computer has been working fine for about a year now, but today when i turn it on everything looks like its starting normally (fans,lights, etc) then at different times during the boot process I get a high pitch non ending beep. Its not the same pitch as regular beeps my board gives. After a few seconds of this (different every time) my computer turns off. I cannot start my OS because it gives a quick chirp and shuts down if i try and when i try getting in the setup it goes in for a few secs then gives me the long high pitch noise for a few seconds then shuts down.

Is the problem heating? Ive never had heating issues before and the air around my processor doesn't seem very warm...

Thanks for the help

What is your BIOS type?
If you don't know that post your PC's Make and model please.

not sure what the bios is but the board is an ASUS P5N32 E SLI if that helps -_- Example of what it does every time... Power on computer - I get my one beep which i always have got telling me everything is fine - goes to windows did not shut down correctly screen giving me options such as safe mode - if i leave it on this screen for a little bit the ringing noise starts or if i choose a start OS option the ringing will start - computer will power itself off after the noise starts and goes for a little bit.

Ive tried taking everything out and putting it back in and still get the same problem.
Ive tried changing RAM sticks one at a time same problem

BTW this noise starts and stops and irregular times numerous times(usually). It doesn't sounds like its coming from the PSU or HDD. Seems to be coming from the board but its hard to tell

Specs:
Microsoft Windows Vista 32-Bit Ultimate
Western Digital Raptor WD1500ADFD 150GB 10000 RPM SATA 1.5Gb/s Hard Drive
ASUS EN8800GTS/HTDP/640M GeForce 8800 GTS 640MB 320-bit GDDR3
ASUS P5N32-E SLI LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard
G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
Intel Core 2 Duo E6600 Conroe 2.4GHz LGA 775 65W Dual-Core Processor
500W PSU

Thank You

The only time I think I have experienced anything like what you describe...is the time that my CPU fan stopped totally and the motherboard was set up to emit this alert to the user. Fortunately, I looked at the fan and noticed that it was not working...and replaced it.

all my fans look like they are working -_-

looked in BIOS (Phoenix) and waited for the noise to start
when it did CPU was at 35 degrees and M/B was at 34

is there a way to check if my 500w psu is actually giving out 500w ? its a crap brand so it wouldn't surprise me if it didn't.

From the way that this is happening I would first suspect that you have overheating problem.

First the obvious, is the inside of the case dust free, especially the heat sink and fan assembly on the CPU?

Is the heat sink and fan firmly attached to the CPU.

If you built this computer, did you use enough thermal compound.

If you download SIW it will show you exactly what your BIOS manufacturer and version is, you will want to download the Standalone version. With this information you can go to this site to match your beep to the appropriate code.
