Stuck in Safe Mode - Time to Reinstall?

Built a new system in the past month (link to components below), OS is Windows 7 Home Premium x64.

After getting the system set up, running most/all of the programs I wanted effectively, and being ready to make final emails setups and file transfers (from my old system), Windows started getting very slow. Like not being able to run Solitaire slow.

No evident problems in Norton Internet Security other than some tracking cookies.

No major resource hogs (memory, CPU, discs) to note.

Saw some errors in the Event Log relating to Nero 9, so I restored to a prior version and reinstalled Nero.

Now I'm very badly stuck in Safe mode. Even after twice restoring to a prior setup that was not constantly re-booting in Safe Mode. Some of the ways I've tried to ask for a normal re-boot:

Press F8 and ask to reboot normally.
Use System Repair Disc
Use msconfig
Use Windows 7 install disc

System passes the boot-up memory diagnostic.

Startup Repair detects no errors.

One potentially odd bit about the msconfig access. Though on the General tab I've got Normal Startup selected, the Boot tab has Safe Boot checked. Make All Boot Settings Permanent is not checked, though. And, when I click back on the General Tab, it still shows Normal Startup.

Just a few more crumbs of evidence that may point to other problems.

1. During startup, I get a No Disc is Detected message. I've treated this as irrelevant from the beginning, as the system boots from the SSD anyway.

2. When I check the Event Viewer log, I see one Warning. 'The winlogon notification subscriber <GPClient> was unavailable to handle a notification event.' When I click on online help, and yes to send this info to MS, I get 'MMC has detected an error in a snap-in and will unload it.' To which I say report this error and the console shuts down.

3. When I get the BIOS startup screen with Press DEL to access BIOS, TAB to run BIOS POST, only the DEL works. The TAB is seemingly not recognized.

So, re-install Windows, or something else? Getting tired of running two systems on a KVM switch that was supposed to be a temporary setup. (Really glad I did set up the system startup that way, though).

Thanks in advance for your suggestions.
