Long Beeps

I have a IBM PC 300 GL machine. Suddenly in the morning when I started my PC it started giving contineous long beeps and would not start. I checked the display card, replaced the memory but still it is giving contineous long beeps. Has the motherboard gone out of order ? I recently heard the the some Magistrt virus erases the BIOS. Need help.

standard trouble shooting would be :

remove everything except
(no harddisk or floppy either)

check if it boots

if it doesn't
replace ram
test again
replace cpu
test again
replace video card
test again
move video card to other slot ( if AGP test with PCI)

if this doesn't work
 change motherboard and/or power supply

if you can get it working now
ad other components one by one untill you have a fully equiped system
depending on the mobo . these beeps can be a faulty or incorrectly connected IDE (harddisk ) cable
These Beeps are the POST - Power On Self Test. If you can tell us what beeps you hear (e.g. 3 short 3 long 3 short) we can tell you whats wrong.

Continuos long beeps normally would indicate the motherboard itself may need to be replaced.  It would be nice to know as Macbeth said, "tell us what beeps you hear."

You could also have something as simple as a stuck key on your keyboard. Look and see if any keys seem lower than others or just try booting with the keyboard unplugged and see if issue continues.  It could numerous things.  See the following for BIOS beep codes.

I took the PC to IBM Authorised Service Center and they said the mobo has to be changed.
