I started out trying to find why the Problem PC would not boot in Normal Mode. It just rebooted at this time and performed an Automatic Startup Repair which failed.
-Automatic Startup Repair - failed.
-System Recovery - Startup Repair failed.
-Memory Diagnostic - No probs found.
In Safe Mode: (Barely stable)
-Malwarebytes' - Anti-Nalware
-found 5 trojans and 6 viruses.
-Removed but still would not boot in Normal mode.
-System Restore - All points failed.
-Modified MSCONFIG for "Clean Boot"
-No effect - still no Normal Mode boot.
-I removed the Problem PC's HDD to scan it for viruses on my (Good) PC when I realized the connection to the HDD from the Problem PC is different than that on my PC. My PC uses standard ribbon cable to attach to Hard Drives. The Problem PC uses a red, 1/2 inch wide, flat cable & no power cord to attach to the HDD. I realized I shouldn't/couldn't connect this HDD to my PC the instant I disconnected it. Oh well. So I put it back.
-The Problem PC BIOS will not detect the HDD that I just removed from it and put back. (It is a Samsung HD160JJP). It only references the CD/DVD player in the disk drive and Boot drive areas of the BIOS.
1. How do I get the drive recognized/detecrted again.
2. AND IF, PLEASE MAY THIS BE TRUE, I GET THE HDD DETECTED AGAIN, If the virus/trojan problem is/was too extensive for me to fix on the HDD can I reinstall windows (Vista SP1) from the recovery D:\ partion? If so How?
PLEASE HELP AND THANK YOU!
