Various BSOD every 30-60 mins

[Dave001]

Hi,
After 1 year of usage my computer decided to give up. About a week ago it started to BSOD continously, only a few minutes after it started. Unfortunately I couldn't save any files because even the ubuntu live CD didn't work.
So I reinstalled windows and everything was fine, for about a day. Since then it randomly crashes with various messages. There have been a MEMORY_MANAGEMENT, a SYSTEM_SERVICE_FAILURE and more errors.

I don't know if it's relevant, but not much before the crashes started I installed windows 8 on another partition and uninstalled it the other day.

Anyway, here are the dump files and some other information. Some of the files contain non-English text, because of my system's language, so sorry about that.

Thanks in advance!

Some indications point to hardware
Start with a memory test
Run for 8 passes.
Then test each stick in a good slot for 6 passes.
If you have dual channel, the results may be incorrect, if shows pass.

If you pass try hard drive.

Result from seatools:
S.M.A.R.T - passed
Short DST - passed
Short generic - passed

Tonight I'm going to run Memtest or the Long generic test in seatools an post the results.

There were some crashes since yesterday, I attached those dump files as well.

Anyway, thanks for the advice.
