i recently opened up my cabinet to clean up inside as it was very dusty. i unassembled each component and vacuumed it. when i reassembled it, it started giving me trouble. as soon as i turn up the power it gives a loud beeping sound. for example when your graphics card is lose it gives one long beep followed by three short, a pause and one short again. in this case each beep is some 2 seconds long and it is continuously repeated. the light on my monitor is green but there is no signal. can anybody tell me what the beep means, and how to resolve the problem? any resource on the internet that can help will do too. my motherboard is a jetway j-7xb and the bios is an award bios dated 24Aug1998. i have 64MB of ram in 2 modules of 32MB each. An SiS 6326 AGP graphics card, a d-link internal modem based on the Motorola SM56PCI chipset, and a Avance Logic als100+ soundcard. harddisks are 2 in number, one 10.2GB and the other 20.4 GB (both seagate U series). any information will be of great help.

sounds like you didn't get some of the cards seated back properly. The beeps are from the Power On Self Test (POST) that runs to check everything out before boot-up.
The One-three sequence says you have a memory board not seated properly. If you have the manual for the motherboard it should have a list of codes in it. If not try one of the motherboard supply sites or:

Hope this helps

Cap'n Krunch.
I already know that the beeps are from the POST. What my problem is, or rather was, that i needed to know the meanings of the beep-codes. By trial and error i found that one of the screws that attaches the motherboard to the base-plate was missing. It is the only screw on the m/board and the rest are plastic pins. My *guess* is that this screw served as a ground for the m/board... after i screwed it in, i got the computer working again.

Another option is to plug in only the necessary devices agp card/ 1 hard drive and boot and if it comes up, bring it down and keep adding 1 at a time til you find the offending card. If it wont com up with your boot drive and video then I'ld have to think you had an esd incident and something got shocked and destroyed. most likely suspect is the modem or sound card though, they seem more succeptible to damage for some reason.
Good Luck!

i am sorry, i cannot rate your answer as acceptable as the link you provided me did not have the codes for award bios. this question is still open, even though the problem is fixed (by fluke), because i still haven't managed to get the required codes so that i don't have trouble later.
