PC keeps beeping when my CPU is working hard


As the topic says, when i scan for virus, copy stuff, etc at the same time.
Especially when my statsbar says im using above 80% cpu and 1GB of 2GB ram.
The PC jus beeps in random timings.

Any idea? I checked the cpu fan, its spinning well.

I'm using P4 3.0Ghz, Abit IS7E mobo, 2GB dual-channel CORSAIR ram.
Graphics: 128MB ATI Radeon 9800XT, 2 x SATA hdd, 2 x CDROM.

You may be having heat issues when the CPU is loaded to a certain degree.
Check your CPU temps when it's beeping.
As a prevenative measure it's a good time to clean out the inside of your system vents and fans.
Also make sure the systems vents aren't blocked where you have it positioned.

This usually indicates an overheating CPU. make sure your heatsink is free of dust and that it is attached properly to the CPU. Maybe clean the surfaces and reapply very little thermal transfer paste.

I would have to agree rindi and PCBONEZ. Adding to that, you may need to adjust the alarm for CPU tempreture in the BIOS. If it is set too low, it will beep when nothing is really wrong. Some BIOS will not give you an option to adjust but will give an option to disable. I do not recommend disabling temp warnings but if it gets too annoying give it a try and keep an eye on system coolers (Fans).

whats a good temperature to set?
I would like a second on this but I think the safety Temp for a P4 3.0Ghz should be set between 80c to 84c. It may be rated higher but I wouldn't push it ove 90 or 95.
"I would like a second on this"

That should be "second opinion".
This depends on the CPU, check it's specs.
I never set my alarms above 75C.

While the "large-die" P4's are rated to run relatively hotter, I prefer keeping them under 75C if possible (that is almost 170F).
