If I set my FSB above 137MHz on my MSI K7T266-RAID I cannot use my USB mouse. The mouse just will not work whatsoever - it doesn't come on or respond. I cannot go back to PS/2, it's just too sluggish - someone please help. I've experienced this before on EPoX 8KTA3, MSI K7T Turbo, etc. but it's really annoying and I NEED to OC MORE!!
