Solved continuous beep , no display/boot

August 3, 2010 at 00:45:25
Specs: Microsoft Windows98, pentium 200 mmx

i was trying to use my win98, it turned on with a very loud fan noise from the psu, still able to see display on the screen but did not boot, got a message about CMOS, so i went to BIOS and load all default settings then save, i was really bothered by the sound of the psu so i turned off the pc and turn it back ON...
this time i only hear a continuous beep, no fan noise anymore since its not turning but cpu/hd fans are..
thought that the prob is with the psu, so i bought a new one, psu/cpu/hd fans are now turning, but still hear the continuous beep with no display/boot
remove video card, sound card, FDD, HDD - continuous beep
ram and cpu only - continuous beep
remove cpu fan - continuous beep
remove ram - continuous beep
remove the cpu - no beep
reseated all card without cpu - no beep
if with cpu - continuous beep

- beep would only stop if cpu is removed, does it mean that the cpu got fried or maybe it happened after i loaded all the bios default setting.. thinking of replacing the cmos battery.. help!

Just in case, clean the RAM edge connectors with a pencil eraser then pop the memory in and out a few times to clear oxide of the sockets themselves.

I realise you have already been that way to some extent but oxide on edge connectors often gives problems when a computer has not been used for some time. You could do the same for the video card while you are at it.

If CPU faulty it would not beep....

Continuous beeping usually indicates a memory problem.

"remove cpu fan - continuous beep" - you're lucky you didn't fry the CPU. NEVER boot a system with the heatsink removed from the CPU

"remove ram - continuous beep" - of course it will beep without RAM

"remove the cpu - no beep" - it won't beep without a CPU. The fact that this happened tells you that the CPU is probably good

"reseated all card without cpu" - no beep - as above, no CPU = no beep = normal

"if with cpu - continuous beep" - still indicates a memory problem

Here's the BIOS beep codes for the Award BIOS:

"thinking of replacing the cmos battery"

It certainly won't hurt to do that but you have to understand the purpose of the battery. All it does is keep voltage to the CMOS chip so that the BIOS settings stay in memory when the system is shutdown. There does not have to be a battery installed for the system to work. If you had no battery (or a dead battery), you would have to enter the BIOS & correct the settings each time the system was booted. The settings would then stay in the CMOS memory & the system would run fine until it was shutdown again. As long as the system was never powered off, the BIOS settings will stay in memory. In other words, the battery is just a backup power source for the CMOS chip for when the system is in a "no power" state.

thank you for the explanation, i have a spare memory.. i will try that but if its still the same, would it be the mobo then?

also how would i test if the prob is with the monitor or vga? i dont have a spare VGA card :(

i haven't use my win98 for a year now, i'm planning to let my kid brother use it ...

it still beeps even with a good RAM, i did see this "Continuous beeping, each lasting about three seconds. The beeping does not stop. Seems to be CPU related. Submitted by baders." in http://www.bioscentral.com/beepcode...

then you may have to replace the processor / cpu.
if not, then you'll have to replace the whole motherboard.
these are not cheap solutions and may cost you some money.
oh well.

"then you may have to replace the processor / cpu"

Incorrect. Processors either work or they don't, there generally is no "in-between". Since he's getting the beep codes, that means the processor is working.

start the pc up with everything connected and push lightly down on the top of the cpu heat sink do you hear a clicking sound?

If you do, hold the heat sink there and the pc will boot.
