Check Disk fails pc random reboots..

Hi guys, I'm currently experiencing some kind of weird behavior of my windows 7.

Sometimes it justs random restarts. The other weird thing, is that this random restart never occurs when I'm in from of pc, it justs happens for example if i leave my computer downloading anything among the night. I've checked it to be sure this was not a trojan, or someone attacking my computer manually, and definitely it's not, it just random reboot.

To keep bizarre on, when i was installing a new game called "Dirt 3", i've got another random restart on every install try. At this point i just realized that something wrong was happening on my pc.

So, I've ran memtests without any bad result. PSU and GPU tests..

What's left? Hard disk of course.
Sometimes when those random reboots appear, my computer is unable to boot in normal mode, I've to enter safe mode, clean shutdown then restart in safe mode.

These win7 fail boot, also happens sometimes after installing Windows updates.

I've tried to check my hard disk, and surprise, when computer reboots and try to chkdsk before win7 starts i get the black screen saying that i can skip hard disk check bla bla bla... when chkdsk starts, reboot again.

Every single time i try to chkdsk computer reboots.

I'm desperate so I've tried just to perform disk checking error from win without repair just to see the logs. That's what i get:

Chkdsk was executed in read-only mode on a volume snapshot.

Errors found. CHKDSK cannot continue in read-only mode.

And if i try to use defrag tool i can't even see my C disk on available disk list (see screenshot):


I've tried reinstalling win 7, but i still get some random restarts (not proceeding) on windows first run after install.

So i'm almost sure that there's something wrong from my HDD, but i can't repair it with chkdsk because pc restarts everytime i try to repair it.

Thank you all in advance for your help :)

Updated my system specs. Thanks for advice.

Before posting, i already read this.

I can't run it, if i attempt to run with repair, computer reboots.

Ok, i managed to use chkdsk with repair disc. Now i'll have to wait and see if issues are gone.
Thanks for help :)
