Okay, I just rebuilt my computer because the CPU died. I got a package deal on an MSI 760GM-P23 (FX) motherboard, an AMD FX4100 quad core processor, and some cheap 4GB memory.
Prior to this all peripherals and both hard drives, a Seagate Barracuda 750GB SATA drive and an ancient Seagate Barracuda 120GB IDE drive, were working fine. I was running WinXP SP3, totally up to date. Everything was fine until I decided to replace my old CD/DVD drive with a new SATA CD/DVD drive -- sometime during the install the original CPU decided to go toes up. It was an AMD Phenom II X4 965 Black Edition.
So I got the new board, the new processor, pulled out the old board, installed the new one, and powered up. Nothing. No POST beeps. I'd forgotten to plug in the CPU power plug. Oops. Did that, I got a POST beep, but no video. Installed a separate video card, still nothing. Took out the free cheap memory, replaced it with my original memory (Patriot PGV38G1333ELK G Series Sector 5, 4 GB stick), and I finally get it to power up.
But I get a message, no bootable media. So powered down, went into BIOS, and no SATA drives are connected. I have no options regarding auto-detecting or manual detection. I have the 750GB SATA drive installed and cabled, and the new CD/DVD SATA drive installed and cabled. The power cable to the drives is good -- the CD/DVD ejects, and you can feel the other drive spin up. The SATA cables are known good cables. The 750 GB SATA drive is good -- it's perfectly readable in my husband's machine, and his box will boot up from it (it has my Windows partition on it).
I've just now taken the battery off the mobo in an effort to clear the CMOS, and in 5 min I'll put it back in. Assuming that doesn't work, any ideas?
