Windows XP hangs at bootup when i am UNDERCLOCKING the CPU..

[Qianglong]

My gf's computer is overheating and it is in a slim profile case. I cannot add anymore fans as that will increase noise. The only option left is to underclock the CPU. I went into the bios and changed the multiplier into 8X 200Mhz

I checked the Heatsink and there is no problem with the assemby, the only time when it overheats is using CPU intensive task

The original CPU is a venice AMD 3000+ running at 1.8Ghz. When I set the new multiplier, the computer will not boot into windows and would lock during the windows bootup logo.

The motherboard is ECS RS480-M and it has one stick of PNY DDR PC3200 RAM.

Please let me know what I am doing wrong?

Check to see if your HSF has good contact with the processor's heatspreader.

Change the heatsink for a better one.

RMA the CPU or the heatsink. If the CPU overheats, one of the two are defective and should be replaced.
