Solved Cannot boot Normal Startup in windows 7

[kgash]

Today, for no apparent reason, my computer would not boot correctly. (Windows 7 64x Professional.)
Msconfig will not accept Normal Startup or Diagnostic Startup but only Selective Startup with only grey arrows in the boxes.
As a result there are only a few services loaded and I cannot start any more. I have no Internet connection, no Sound, etc.

My system has 3 hard drives with a different OS on each: C: Windows 7, D: Windows XP and F: Windows Technical Preview (10). XP and 10 boot normally and all functions work correctly.

I have a clean image file backup which I installed using my rescue disk but the reinstallation of the image did not fix the problem

I cannot run Backup and Restore, sfc /scannow,
Device Manager shows everything normal.
I ran both TDDSKiller from cd and found no malware.
I have run out of ideas other than a complete wipe and reinstall so I am hoping that someone out there in cyber space has some useful suggestions

Thanks for your quick response.
I have solved the problem but I don't know what caused it. After thinking about all of the different issues at fault, I wondered if somehow the BIOS got screwed up. My Gigabyte MB has a CMOS reset switch so I used it, rebooted and the problems were gone!

I have found that sometimes power surges or power loss while the computer is on can cause this problem. It doesn't happen every time but it has happened to me on a X58 motherboard or older.

Yes, i have heard of that happening. I have a good UPS protecting the pc from such events so I don't think power fluctuations were the cause. Perhaps it will remain a mystery.

Yes wll as Layback says it can be outages and even brownouts which I think are just as problematical or worse. The USP is a good idea and if this happens again I thnk maybe you have the answer in your reply - well done
