Mouse Freezes - HDD Shuts Down

I have two problems with my Vista Home premium system running on desktop (HP Pavilion - 32 bit):

Recently the mouse has frozen in place while on the net, and simultaneously the hard drive shuts down.
Ctrl/Alt/Delete does nothing. I have to do a hard shut down. System then works normally for a brief period until the freeze reoccurs.

2. Thinking this might be caused by a recent update, I attempted to turn the system
back about a week, using System Restore. Online instructions indicate that I should have the option of choosing an earlier restore point than the only one given, which is today's date. I entered a date one week earlier, but it reverted to today's date.

I've run Avast virus scan, Malwarbytes, and Windows Defender scan with negative results.

I've run the other steps suggested online for this problem, but no fix.

Can someone please point me in the right direction?

How long does it take from cold boot to lockup? If it is 1/2 hour or less whenever I have run into this is has been due to hardware. When it hits a certain temperature the machine hard locks. With me it happened after adding a network card.
