Windows 7: BSOD on start-up. Dump-files attached

I think I've followed all the BSOD posting instructions. BSOD happened the first time after I finished downloading GW2 for the free trial weekend. I've tried system restore twice and it worked for a day, then back to the same thing. I have no idea what I'm doing. Thank you in advance for any help!

Hello SpiritSprite, Welcome to SF

First off if your OCing in anyway stop, return everything to stock settings for the purposes of testing

If you havent already, fill in your system specs so we know what we are dealing with
System Info - See Your System Specs

Run some scans to check against virus or infection
http://support.kaspersky.com/5350
Windows Defender Offline

Run some basic hardware tests
RAM - Test with Memtest86+
Disk Check (windows based check)
Hard Drive Diagnostic Procedure (bootable disk check)

Theres a lot of dumps there i ran the ones for december and they are a mix of
0x1E KMODE_EXCEPTION_NOT_HANDLED BSOD Index
0xA IRQL_NOT_LESS_OR_EQUAL BSOD Index
0x50 PAGE_FAULT_IN_NON_PAGED_AREA BSOD Index

I would run through the above and in particular memtest, make sure you run it for multiple passes or preferably overnight

Been having a look through your drivers and there are a few that pre date windows 7 might be worth seeing if you can update them

hamachi.sys 19/02/2009 10:36:41
AtiPcie.sys 05/05/2009 15:00:22
spldr.sys 11/05/2009 16:56:27
GEARAspiWDM.sys 18/05/2009 12:17:04

and a few that are still quite old

k57nd60a.sys 06/08/2009 11:44:32
AtiHdmi.sys 30/09/2009 13:54:46
RTKVHD64.sys 09/11/2009 09:13:59
amdxata.sys 19/03/2010 16:18:18

google the driver to see what it belongs to then visit manufacturers website to see if there are any better ones available
