Various BSODs playing recent games for 7-8 months

[timd]

I bought a Novatech PC in December last year and after a month began getting BSODs firstly when playing Assassins Creed 3 and then with other new games such as Bioshock Infinite and Battlefield 3. There didn't seem to be any trigger within the games, just a random crash at random times - anything from 30 mins to several hours after starting to play. The only pattern was the games it crashed in and that, after the initial crash and restart, the PC would bluescreen very soon after loading up the game again.

The errors have included:
0x1A
0xD1
0x50 (most often)
0xA
0xBE
0x3B
0xF4
0x24

I've run disc checks, memory tests, GPU stress tests and all have come back negative. The only possible lead was running a CPU test in OCCT (Home) which causes a BSOD pretty quickly every time.

As the PC is still under warranty I also contacted Novatech who suggested I try removing the Creative X-Fi card and front panel as I added them from my old PC. This seemed to help reduce the number of BSODs but they did still occur, particularly in BF3. I've left the card in recently as it's the only way I can use my 5.1 speakers and the BSODs have been much worse - even occurring in Minecraft a couple of times and when I left War Thunder on idle on its menu for an hour or so.

I've attached my SF Diagnostic output below.

Any help would be great. Thanks!

Start with the following:

Thanks for the suggestions, they are much appreciated.

I have already run Memtest86+ several times and it hasn't flagged up any errors.

I've just had a go at the IntelBurnTest though and can't even let it run for a whole second before core #2 and then core #1 (always those two and in that order) go above the safe temperature!

Processor:        Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz
Clock Speed: 3.50 GHz
Active Physical Cores: 8
Total System Memory: 16343 MB

Stress Level: Standard (1024 MB)
Testing started on 01/09/2013 15:07:34
Time (s)		Speed (GFlops)		Result
Testing ended on 01/09/2013 15:07:40
Test Result: Stopped by user.

My idle temperature is ~30°C and the max safe temperature is 67.4°C (I think: ARK | Intel® Core) but after a fraction of a second into the tests cores 1 and 2 are up at 73-75°C and 0 and 3 are around 67-68°C. It seems that this is too short a time for the test programme to record any results.

Is this something I should be concerned about?

Hi, sorry to bump this one but has anyone got any other suggestions?

Thanks
