I am looking for a solution that I haven't tried yet. I'll give the short version of events here: I have had to purchase a new mobo and cpu because of a power failure damaging my old mobo. First, I replaced the power supply and then is wanted me to repair Windows. Did that by hooking into another machine as I was in the bsod loop on mine. Once I "repaired", video went away and there were no boot beeps. Reset my memory and ran a memory test. Memory is good. Rebuilt the MBR using cmd mode and got the hdd to boot when hooked into the other machine. When I moved it back, the video had gone. Tested my cards on another machine; they're fine (nvidia 450 gts). Dr. Debug was no longer responding and on some searches discovered that the mobo is/was most likely dead. My new one is an Asrock Z97 Extreme4 with an Intel i7-4770K processor. I also have a new 750 power supply. I have tried all the suggestions on here. Basically, when i try to install Windows 7, it tells me that the controller setting for my hdd is not set in the bios. I have tried the unplugging, reseating, new sata cord, refreshing bios, resetting bios, reformatting the drive (3 times now), using diskpart.exe to set up partitions, scanned the hdd with all available scans, i.e. WD scan, chkdsk scans and fixes. I visited the Asrock site and downloaded the most current hdd drivers to a thumb drive and had Windows browse there for the drivers. But, Windows says they are not there. I know my Windows disk is good as I had to install Windows just last week on a new build for my son. He did not replace his hdd; just reformatted it and installed. The hdd is a WD1002FAEX 1TB. All the scans show is as healthy with nothing corrupted. I do have a surge protector and everything was (and is) plugged into it. But, the old mobo had been through several thunderstorms and blackouts. Not sure if they just caught up to it and burned it out or not. What can I try next?
