Windows freeze (mouse is ok) after a while

[fanjo]

Hi all,

Little background: computer was working like a charm on Windows 7 Ultimate, 64bits. A week ago, I started to have BSOD everytime I left the computer for around 10/15 minutes. I updated a lot of drivers etc.. then I formatted my C:/ and reinstalled Windows (still 7 ultimate x64 )

So fresh install, antivirus scan is ok, graphic drivers updated, all windows updates done, I even updated the firmware of my SSD (Crucial 64Go) on which Windows is installed and flashed my bios to the latest version.

Now, still after a while, my computer "semi-freezes" : depending of my use at the time, a video playing will stop, a browser will stay on the page but won't open new pages and a click on a folder of my Desktop will open a blank folder. I can't Ctrl+Alt+Suppr either.

As there is no BSOD, nothing appears in C:\Windows\Minidump ...

Any idea? I'm thinking of a hardware problem but didn't manage to pin it down...
Thanks

Hi all,

Just happened:

1) everything normal for about an hour. Then Chrome is not reponding
2) 30sec later, desktop and desktop bar disappear. I had uTorrent opened, which continued working.
3) 1min or so later, uTorrent is also shut down and then computer is rebooting

4) reboot failed, frozen on POST screen. I had to power off and power on and here I am...

?!?!...
