BSODs and IE crashes clean install of win7 RTM 64-bit

Dear gurus

Where do I begin ...

everything was running smoothly for 2-3 months on my legit RTM copy of 64-bit win7. I've been dual-booting XP 32-bit and win7.
win7 is installed on its own 1TB WD black caviar drive. XP is using the other 2 x 320GB WD drives.

Anyways, to cut a long story short, about 2 weeks ago I started getting BSODs with win7. Lots of them! I even reformatted the 1 TB drive and did another install, to no avail. XP works flawlessly btw.

Made sure I had the latest drivers for video etc.

Ran memtest86+ and all ok.

(I did have issues with a couple of those Team Xtreme Dark 1GB memory sticks several months ago when my PC (with just XP installed) wouldn't boot. So I replaced 2x1GB Team Xtreme sticks with 2X2GB Gskill sticks and all seemed ok and, I thought, would be useful to have 6GB for 64-bit win 7.)

I currently run 2x2GB Gskill + 2X1GB Team Xtreme memory sticks on a GA P35C-DS3R mobo.

Now I SUSPECT that I'm having memory issues again but I'd like one of you dear folk to inspect my minidumps which I've attached.

I'm at the end of my tether so would really appreciate any help :)
Thanks

I believe you are correct about the memory problems. Mixing different brands of Memory is probably the cause of your problems. Try running the GSkill only.

The .dmp points to the graphics driver as the culprit but that is a common error and may not mean anything. You can try some different drivers maybe but I would change the Ram out myself.

And I believe you are correct, Chev Thanks!

Got rid of the 2x1GB Team Xtreme and she's been steady as a rock all morning!
Maybe as more users are moving to 64-bit OSes we're seeing more memory issues due to these OSes using more than 4GB?? Dunno ...

I've heard that putting 4 sticks of memory into my motherboard - GA-P35-DS3R (rev. 1.0) - can be a problem.
Do you think I should buy 2 more sticks of identical GSkill 2GB and give it a go?
