Random BSoD

ok here we go.
about a week ago, at random, my pc starts getting different BSoD error codes.
ive reinstalled windows multiple times, ramtested for 20 hours with 24 passes and no errors (scanned 2 other times for less amount of time)
ive used seagate's HDD tool with nothing and MS built in HDD tests
i had 2 ext HDD hooked up, unplugged them
updated vid card drivers, only chipset i could find was for vista so couldnt get those, but did get the sata controllers
it can happen as i am shutting down my pc or even at idle tho idle is rare
only things i can think of tryin is changing out my wifi card, add a usb card to replace the onboard, and maybe even try to see if one of the HDDs is still the case by unplugging individually and installing windows on my 1tb drive
my windows at the moment is not updated, previously was up-to-date with up-to-date drivers, 2nd and 3rd go was in the middle of updates when i started gettin, so 4th time i didnt update at all except some basic drivers
if i left out anything i am sorry
i normally can figure pc things on my own but this is driving me crazy
thanks in advance

no activation or updates as of yet like i said above, its genu. but i really dont wanna try to do all the updates ect yet without fixing or atleast having an idea because my slow internet

Without this information we cannot proceed.

Windows Updates and Activation

Its not an update im asking for, its to check the validity of your installation.

Your BIOS is dated before windows 7 was released, so i need to check genuinity of the install,
which is needed before we proceed please.

Cheers

Dave
