For whatever reason, it stopped to BSOD two/three weeks after the first incident. However, it kept freezing every hour after reboot. The small cursor circle keeps rotating, but everything is blocked, I basically can't do anything except rebooting and get back to normal for roughly an hour.
When the screensaver is on, I'm moving the mouse to reactivate the whole thing, but the only thing appearing is only my wallpaper (no taskbar, no icons, nothing).
I've been running the latest MemTest issue, no errors found (5 passes).
I actually did format to have a proper install, it didn't change anything. It kept bugging the same way on a clean install.
I cleaned all the viruses who might have found a home on my data harddrive, nothing changes.
Thing is, as I reinstalled everything, it's still impossible to install the drivers of my USB hub (front USB plugs), and I can't install 4 Windows fixes through Windows Update (Code 8007065E / Code 800B0100).
My system :
P8P67 Rev. 3.0
2 x 4 Go Kingston
SSD Crucial 128 Go (where the system is installed)
Western Digital 1 To (data)
If I knew what was going wrong, I would have bought a new piece of hardware (as it doesn't seem to be a software problem). But as I don't have any clue of what's going on, this is my last chance to understand what's going on by posting here. I might suspect my SSD, but this is just random.
Last thing, I noticed the tendancy to see appear some BSOD when I was playing loud my 50 W tube guitar amp. But hey, still random guess here .
Thank you everyone, and please forgive my few mistakes as I'm not an English native .
