Alienware overclocking / underclocking failure

I have recently aquired a m17x r1 with intel q9000 4gb ram gtx 260. Bios a05. My problem is that if I raise the fsb even by one it doesn't post and I have to hard restart the computer three times. I recently updated the bios to a05, but that didn't help. This happens if I raise or lower the fsb. I also tried lowering the memory speed and raising / lowering the fsb. Any help would be appreciated. I'm new to the forum and have found it to be very helpful so far. Thanks in advance.
