Regarding your post #42, you wrote you were looking for some restore points but found none: I went back through my notes and on June 5th, my husband Joe went into the System and Security features and restored the system back to 5/31/2013. There was another date to choose from, 5/22/2013, but he chose 5/31/2013. It restarted to a blank screen. Then he ran a PC Doctor Full System Test. I wrote down the list of items that failed the test;
1. Hard Drive: Smart Extended Self Test
2. Hard Drive: Surface Scan Test
3. SMBIOS: Standards Test

I don't know if the above means anything or will help, but I posted it anyway.
