Startup Repair loop -repair installation?

Dear all,

A little over a week ago, my system BSOD'd (too quickly for me to see the first time) and eventually after a number of restarts rebooted normally and ran fine for the next day or so. The following day, I was unable to get the machine to post, with fans spinning but not a lot else. Resetting the BIOS seemed to work, but I was then stuck at the startup repair screen, looping without success. I had a spare HDD so installed another copy of 7 Pro and managed to book ok, but after several more BSODs it looked like a hardware fault. I changed the motherboard today for a similar (same chipset) model and reconnected the original HDD, but once again I am stuck at startup repair with the following error:

Problem signature:
Problem Event Name: StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown
Problem Signature 04: 21200795
Problem Signature 05: AutoFailover
Problem Signature 06: 24
Problem Signature 07: Corupt Registry
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033

I cannot get into Safe Mode in any guise without the system heading back to the unsuccessful startup repair. I have also tried the advanced F8 menu/ignore non-signed driver option, however this caused a fast and immediate BSOD just after the Windows splash screen -way too fast to grab any kind of info.

If at all possible I would like to retain the programs/files already on the HDD (looking through the inventory with Command Prompt, it seems everything's still there). I've seen reference to a Repair Install on this forum, but the supplied instructions state it needs to be performed from within Windows. I was hoping for something similar to the old XP version?

Any help would be gratefully received.

Best wishes.

Stu.

You may find Startup Repair Infinite Loop Recovery helpful.

You will need a Windows 7 repair disc or you can use the Advanced Boot Options to get to the System Recovery Options.

Then try the steps in Startup Repair Infinite Loop Recovery. Note the warning:

Many thanks for your prompt reply.

I went through all of the steps in the Startup Repair Infinate Loop Recovery link but after the Starting Windows splash screen, just before the animation appears I was taken back into Startup Repair which once again was unsuccessful.

I was wondering if anyone had any other suggestions I could try?

Best regards,
