Random shutdowns. 2 long beeps...

November 30, 2005 at 10:13:42
Specs: XP pro, 1 Ghz Pentium III/192 SDR

The symtoms:
Sometimes the computer screen will suddenly go black, and I hear 2 loud beeps (about 1 to 1.5 seconds long each), and then nothingness. The computer is still on, fans running, but that`s all. Restart the computer, and same 2 beeps, followed by nothingness. Unplug computer, check connections, unplug/replug power supply, HD`s, etc., and turn on computer...it starts without a hitch (sometimes). Othertimes, I have to repeat the process a few times before getting it running again.
Sometimes, when it would restart, it would say, "windows has recovered from a serious error" or "system crashed due to overclocking." I`ve never overclocked it, but I checked the heatsink and it had a lot of dust, which I cleaned out (could the CPU have gotten too hot due to the dust, then thought it was overclocking?). Everything ran fine for about a month, when suddenly, the same thing happened again with the crash and 2 beeps. However, after cleaning the heatsink, I no longer get the overclocking message once I finally get it to bootup. Everything will be nice for a few days, and bam! It happens again. Sometimes, when I turn on my computer, I hear the usual short "beep!" and then nothing but a blank screen, with fans running. I have no idea what it is, but I`m suspicious of the power supply, cause when I turn off the computer, I always hear a kind of loud high pitched whining noise coming from it (this is after the computer is completely turned off). When I unplug the supply from the wall, the high pitched noise dies out.

Some more info on this system:

Motherboard: Future Power FP-VA694+
BIOS: Award Modular BIOS v6.00 PGN
Power Supply: Hivision MAX-300P (300W)
(I couldn`t find any info on this one except for a post by a guy who said it blew up in his system one time!)
RAM: 128 MB SDRAM 133, 64 MB SDRAM 133
IDE Primary Master: WDC WD1200JB-00DUA3
IDE Primary Slave: Maxtor 33073H3

CPU temp: 30 C/86 F
System temp: 26 C/78 F
FAN 1 speed between: 3581-3723

I`m a bit of a beginner, but I want to learn more, so any input would be greatly appreciated. Thank you, and sorry for the long post!

Hi:I think your problem related to the Following :
a) overheating
try taking the cover off the computer tower, blow
out the dust and junk inside, then point a housefan
at the inards. Run the computer like that for a while. Does
the problem go away...If so, make sure that all fans are
running inside and if so, you might want another fan...

b) power supply is failing ,Try another power supply.
if it shut down automatically, that could be P/Supply problem
Check the Power supply Fan is operating, ( over heat )
And check with another P/supply unit (could be Power supply unit circuit problem )
c) motherboard issues
d) CPU died/failing or Overclocked or has a Trouble
E) A virus or a Trojan

Unless its a physical/electrical problem of course.
Bon Courage..

Hi, just try to hit "Del" key at the start of your pc (if it will start :))to enter setup. Then choose "load setup defaults" or "load bios defaults" and "save & exit". More helpfull could be this link: http://www.computerhope.com/beep.htm

Make sure the power supply fan is not plugged up with dust bunnies and sufficient air is blowing through the power supply. Also check the power supplies input holes to makes sure they aren't plugged up.

Or you think you might have not Overclocked. Have you ever tampered with the BIOS? There are already tons of OC'ing options in there. You might have changed one which means you OC'ed. Also, have you added anything to your computer b4 this occured?

First, thank you to everyone for your replies.

I`ve checked the power supply fan and it`s not clogged at all. The airholes on the inside are ok, too. There`s plenty of air going through.

I haven`t messed with the BIOS, but this is not originally my computer. Maybe the previous owner did. Does anyone know how I can check this out?

One of my friends put in that Audigy soundcard and the WDC WD1200JB-00DUA3 hardrive for me and I seem to recall the problems starting after that.
