A quick way to finding out what blue screen error codes you've been getting is with this utility:

Googling the blue screen code may get you some informative results, or post them here.

When you say "restarting every hour" is that regardless of what you're doing on the computer? Does it happen with the computer is unused at the time?

What are your system's temperature sensors reporting?

Hi thanx.
Temp is very low.
As i can see its unrelated to what i do. It restart just as often if its not used. But i will have to check it out.
Hmm
Does that say something?
The blue screen is seldom there and in a splitsecond it restarts
Thanx for tip! Will look into it.

Click Start button and type in "Advanced system settings". In Advanced system settings, under "Startup and Recovery", Click Settings button. Uncheck "Automatically restart".

After you do that it will sit at the bluescreen until you power down or press reset or CTRL-ALT-DEL.

If you had a Crucial M4 SSD, I would say that you had the "5000 hours" bug, and needed a firmware update. But you say you have a Samsung SSD. Strange.

Since you are using 16GB of ram (2x8GB sticks), i'd recommend trying just one stick at a time to see if that could be causing it.

Thanx guys. You are stars 🙂 !

I couldnt use the nirsoft tool, as my crashdumps aparently didnt record, but this worked.

The problem was the vuhub.sys file.
And i located it aparently came from using the virtual usb hub for my new Asus u68 Router (that have been otherwise been an extremely solid product so i didnt suspect it).

Yeaa i had an M4 earlier that failed in an notebook - and in some ways the random errors looked like a ssd error. (have had a lot of ssd errors so only samsung from now on 🙂

But its like you just need the right approach for attacking the problem and i havnt thought of using the info in the bluescreeen. lol. Seems very straightforward ones you are told it. But its 20 years and back to the Window 95 beta days i had this sort of behavior so i kind of forgot how it is working with that.

Samsung has had their share of issues as well. For example, the 840 EVO is known to "forget" data after a while unless the blocks are refreshed with Samsung's tool. They also have a newer firmware out that automatically refreshes the blocks, at the cost of write cycles on the NAND.

The underlying issues is that the first generation TLC NAND used in the 840 EVO decays much quicker than they expected and become corrupted and then unreadable during normal usage.

But anyway, the main point is that if you completely avoid an entire manufacturer of SSDs (or any part really) just because one of their models has an issue, you will quickly run out of manufacturers.
