Help, Overclocking disables my USB ports??

[v3rax]

I play COD4 onlilne and soon after I installed the game and started playing I begin to overclock my CPU.

About 10 minutes into a game, my mouse and keyboard (both USB) would begin to act funny. For instance, my right mouse button is what I use to "aim down the site" and it stops working. Some of my keys set up on my keyboard stop working too.

If I put everything back to default in the BIOS, I don't get the USB problem.

I was using an Asus P5K Premium and thought maybe it was the mobo, so I bought a new mobo, and got a Abit P35 Pro, also got a new mouse and keyboard, reformatted, yet I get the same problem when I overclock.

Is there any way to stop this from happening when I overclock?

Yeah, lock your PCI bus to 33 Mhz, and your PCI-E bus to 100 Mhz. Of course, it could be happening because your power supply doesn't have enough power on the rail that those Asus boards use to power the USB ports, and overclocking the CPU exacerbates the problem.

Well, I found where to lock my PCI-E bus to 100, but I couldnt find where to set the PCI bus to 33. It was not in the area where the PCI-E was in the Guru.
