System Restore (need to be in "normal mode") & Last Known Configuration don’t help.

Chkdsk fails on reboot and scandisk does not run in safe mode

BIOS settings have been reset to default

I had Symantec Anti-virus w/Live Update, but that has not been performing well lately and I deleted it as Live Update was not actually Live Updating it. Any anti-virus software I dl, it refuses for some odd reason. What I do have installed is Malware Bytes & Wise Registry Cleaner 4.

I have seen most tech forums on the Web and none of them have been providing me a right answer, so I will take suggestions from here. Thanks to those that help me, I truly appreciate it. 🙂
