My system is hung pretty badly, nearly frozen.  In task manager, The System process is utilizing 99% of resources (System, not the usual System Idle Process).  Reboots take about 6-8 times normal longer.  I have run Dell Diagnostics, which took 18 hours, but the only thing that showed a failure was

IDE Disk 3 and I don't believe I have  one.  My original C drive is partitioned into a C and a D.  I got passes for Disks 0, 1, 2.  Clicks

 

Rebooting in safe mode does not help at all.

 

Does anyone have any insight that would help me?
