Computer wont post.
RMA'd the motherboard and just got the new one today. I sincerely dont think the CPU is toast.
Therefore, can a PSU be bad, yet still turn on the fans (3), video card, and hdd but not post.
Is this possible?
Thanks

Yes, and there are other possibilities, like the ATX12V cable not being hooked up, having a PS/2 keyboard plugged into the mouse port or vice versa, etc. I made a document with a list of some things to check, it's the third link on this page: http://www.mechbgon.com
