That's unusual a bios update corrupted Windows. I'm glad to hear you got a couple crash free games in.
One thing I just remembered about HCI Memtest is it will start testing the page file on the SSD drive if the test size exceeds the amount of free RAM available.
I had the page file disabled on my PC so MemTest would tell me "no more RAM available" when I ran out of available free RAM. All this is mentioned in the Memtest manual on the website.
You definitely don't want to test the pagefile because then MemTest turns into a SSD test instead of a RAM test.
Yeah a BIOS update shouldn't technically upset Windows although, a lot of what is configured in the BIOS can influence functionality of specific parts of the OS I guess. Either way, something screwed up in my primary profile (it could just be coincidence, and a corrupt set of files has decided to really throw their toys out of the pram). The good thing is that the secondary profile seems to be very stable.
Thanks for the heads up on Memtest. I do have a pagefile so it should be ok if it does dip into it. I have 64Gb system RAM so hopefully, it'll not need to but either way, I'll give that app a go tomorrow.
