I turn on the computer, and the POST starts but when the test is going to the hard drive, the test stops right there and halts; I don't hear the POST error beep code at all. I know is not the power or the SATA cables, and I don't think that's the problem.

A couple of days ago, it took me a couple of trys to get the computer to boot and load Windows 7, and after that, it gave me a blue screen system dump error, it rebooted on its own and I could use the computer for hours after that with no problems at all. This worsening of the booting problem just started a couple of days ago, and I'm unable to boot the computer at all as I describe above.

How do I clear the CMOS as you suggest, to see if it fixes the problem?

Thanks very much.

OK. Now that you've ruled out the HDD as the cause of the problem, try using just one known-good stick of RAM instead of multiple sticks during your trouble-shooting.

Have you tried a different HDD? It might be that your current one is failing. Try running the DOS version of Seatools: http://www.seagate.com/support/downloads/item/seatools-dos-master/

Also, if you want to try clearing the CMOS, most motherboards have a small button with "CMOS" or "CLR CMOS" written on it. Press that button to clear your CMOS.

Another way to clear the CMOS if your motherboard doesn't have a dedicated button for it, is to pull out the CMOS battery. That's the little round battery on the motherboard. Pull it out, and reinsert it after a little while. This should reset your CMOS.

Yes I have. I even tried connecting one with a PCI bus and the tradional power supply socket and the jumper set to Master.
