i have a problem with this computer ( yes, the one i'm using now) because
everytime i boot it up it just shuts down after a few seconds with unusual beeping sound for about five times then it shuts down.

i tried to disconnect the hard disk then it will boot up normally and don't have that beeping sound.

i tried using a different but defective hard disk and it will not shut down. but when i connect again the hard disk (not the defective one) the problem comes back. then after maybe half an hour of plugging/unplug it to the AVR trying it to work..
it will eventually boot up normally without beeps..?..


what do you think the problem??

More about : shuts seconds

I would hazard power supply.

What are your specs?

What is the exact series of beeps you are getting (long, short, how many and in what order). The beeps are most likely an error code trying to tell you what is wrong...

ripped from a couple of sites ... google is your friend.

Most likely sounds like your AGP or PCI-E graphics card has become dislodged and needs to be reseated.

Remove the screw on the back of the slot first ... if it is screwed in.

If it is 5 beeps indicating the CPU then power down and remove the cpu, regrease and reseat it and put the HSF back and lock it in ...

I can post a guid for you depending what cpu it is if you need help with that.

Good luck !!

If you have a working computer that has not been moved and it starts acting weird, first suspect is always the power supply.
May 1, 2009 1:54:02 AM

Reynod, good advice. It sounds like a CPU/HeatSink issue. Allura we don't know what kind of MB you have. If your MB has a Hardware Monitor in the bios start the computer and go directly there. See if your CPU temp is rising. If so follow reynods advice. Also check for excessive dust.

I paid him to type that ... lol

Check all ideas you get from the forums OP.

Post count means nothing in terms of knowledge ... some of our smartest users seldom post ... but read everything.

Hopefully I am not the opposite.

reynod, I laughed all the way to the bank. Is there anything else I can do for you.

it seems like my pc needs to be "warmed up" for it to work normal..

i boot it up without the hard disk then i will leave it up for about 15 mins?

then after 15 min i will turn off the avr (because i got no way to turn it off other than shutting off the avr or unplugging it o.O)

then i will reconnect the avr then its ready to boot up.






how is that?

btw. my pc has an "old school" hardwares.. cos i have this way back in year 2002, maybe...

very long time ago.. :)
