In the last 7 days, my desktop has been freezing up sporadically, 2 - 60 minutes from logging in. I have not installed any new software, for the exception of upgrades such as Adobe, VirtualBox, etc... I have been imaging (Acronis) back to a previous good image (created 4 months ago) and avoid upgrading any software. It seems to rule out on a software level.

I need to test RAM (3 years old), Hard Drive (6 years old), SSD (3 years old), graphic card (8 years old), CPU (3 years old). Could you name a software that can test these hardware?

I doubt it is the graphic card. Symptom: When it freezes, I get a weird noise (as if buzz out) and then a still picture of the screen. I would have to hold down the Power button to reset.

Thanks
