Okay. After running Chkdsk on both my HDDs, I've determined that they are clean and not the problem. So. That's one thing down.
A few other Error Messages (not counting 'Warnings' or 'Information' from the logs) :
System:

Syntax error in manifest or policy file "C:\WINDOWS\RtlExUpd.dll" on line 3.
Initialization failed because the driver device could not be created.
Windows Setup encountered non-fatal errors during installation. Please check the setuperr.log found in your Windows directory for more information.

Only 1 Security Failure:
IPSec Services: IPSec Services failed to get the complete list of network interfaces on the machine. This can be a potential security hazard to the machine since some of the network interfaces may not get the protection as desired by the applied IPSec filters. Please run IPSec monitor snap-in to further diagnose the problem.
The computer's parts are all newish; Asus A8N5X motherboard, Athlon 2800+ 64 X2 CPU....will the specs help you?
Thanks for all your assistance thus far, and I'll eagerly await anything you can do to help.
