Have you tried looking into upgrading your motherboard BIOS? This is a common issue amongst prebuilt PCs and I have hypothesized it is due to installing newer hardware that the BIOS is not equipped to recognize.

Other good things to try are flipping your CMOS switch, resetting your BIOS to default settings, defragmenting hard drive, running ccleaner to clear out any old registry entries left by old drivers and other things, and I can think of a fresh OS install onto preferably an SSD being a final solution.
