Greetings...
Basically i use a KVM that has USB mouse/Keyboard instead of PS/2, if i run my Opteron 165 @ 2.6Ghz or any speed much over stock the pc would refuse to boot up once it pasts post, only a blinking cursor, finally found the issue when i booted up without the KVM connected, once windows loaded i connected it and it works 100% fine. CPU/Memory is rock stable @ 35hrs prime95 and 2 days memtest. Is there any issue with Nforce 4, overclocking and USB that i missed?
