System Timer IRQ Conflict w/Mobility Radeon 9000...HELP please?

Hi. My notebook shut down after emitting 4 beeps. After giving it some time to cool((thought it overheated)) I restarted it and once again got 4 beeps...then NOTHING! Of course, that was an error code for System Timer failure...so after many tries to get back on my pc without even being able to get into my BIOS...I FINALLY got it to boot, after again hearing 4 beeps. I went to device manager-right click properties on my System Timer, under Resources, it gave me this: interupt request 00 used by Mobility Radeon 9000. So I clicked on my Mobility Radeon 9000 Display driver, and went under resources, but it said NO CONFLICTS, and the setting for the IRQ was 16, not the 00 my System Timer was telling me.....HELP please if anyone can offer suggestions...I'm running out of ideas...
I have a ECS G732 Notebook
Intel Pentium 4 CPU 2.80GHz
512DDRAM

Anyone??? Any suggestions??? Besides taking it in somewhere???? Thanks...
