Thanks for the link, installed the latest version (great program, congratulations
Passed the Stress and Quick Test, and also all other hardware tests I thought relevant (couldn't check every single one at the moment, like AVI, sound etc). M.board, CPU, RAM and video card all passed.
Interesting: while transferring the installer file from the USB stick to the desktop, the PC froze and this was the second freeze while that USB port was active (front panel, a custom USB hub that's not part of the m.board - contains 2 USB ports and a 4-card reader.)
I didn't try any more file transfers there. Toolbox's test on that USB port passed, one of the card reader ports test failed the first time. I run the card reader test 3 more times and it passed all three.

I've now disabled via BIOS all those USB ports to see if the PC lasts more than a few days without freezing.
Irrelevant question: if I buy a second key/license, do I need to enter a different email address during activation, or can I use the same as the one linked to my first key? Thanks again.
