Severe stability problems after upgrade

[papa G]

I upgraded my pc recently and have had crashes and reboots since. I think it is either my motherboard, unsigned drivers (note plural), or PSU (not likely though).
The parts upgraded were my memory, HDD, CPU, and motherboard (see profile for details).
I have run memtest (4hrs) and it was fine. I ran chkdsk and it seemed to complete okay. It did reboot automatically when finished.. is that supposed to happen or did my pc just reboot?
I crash when playing games, when copying files from one partition to another (on same HDD), when installing, and listening to music.
MY SYSTEM IS NOT OVERCLOCKED.

These are some BSOD messages:

I have attached some minidumps and some output in Event Viewer.
PLEASE HELP!!!!!

Sorry for the bump, but has anyone had a chance to look at the minidumps?

Alternative web site?

Can anyone recommend another website/forum which I can try to sort the problem? So far I have tried PC Perspective and DFI-Street.

Hello and welcome to Techspot.

I believe you have a ram problem.

Go HERE and follow the instructions.

Please note. Some faulty ram can pass memtest.

Check that your ram is compatible with your mobo.

I've run memtest again. This time for 10 hours. It had failed on test 8 so I guess this means it is my memory which is at fault. Lets hope they can exchange it.

swap out your memory.....
random crashes are a hallmark sign of failing memory.
If memtest came up with bad memory then one or more sticks of memory have gone bad.
remove the bad stick
