Horrible BSODs

Hi!
Been fighting for around three or four weeks with BSODs. Been around computers for a long time and problems usually gets fixed. This issue however is slowly but surely winning over me.

**ERROR DESCRIPTION**
I am getting all kinds of BSODs, which seem to appear totally out of the blue. Can't seem to find a common unifier in any case (some activity I was doing or a process I was using) either.

**SETUP**
3000+ AMD64 Venice Core
AN8 Fatal1ty Motherboard
2 sticks of 512 DDR (BH5 is the name I reckon)
500 gig SATA Samsung (Brand new, used as OS-drive)
200 gig older Maxtor Drive (used purely now as a slave drive)
Asus GF8600GTS

**TRIED REMEDIES**
Bought a new harddrive today, since it got so bad it just threw a BSOD in my face on the old one during start up, PRECISELY when the windows mousepointer was shown. Maybe I jumped the gun on this but I also needed a new drive.

I got two sticks of memory, and I tried running the computer on a single of these (tried both) during my last startup failures but it didn't matter. Made sure I didn't use a single memorybus in case if one of the busses was broken. All this to make sure it wasn't a faulty ram.

Before the startup BSODs on my old setup the problems were similar to the ones I'm having now, BSODs slamming in every now and then. My friend recommended me to up the voltage to the memory and it actually seemed to work.

Maybe it is so simple that it's the memory that aren't working properly, but I tried running them individually (although with the exception that the startup BSOD appeared every time, contrary to now when it only appears sometimes.

Below is three dumps that I got today. Of course they show different errors but I thought you guys might be able to see some unifier in these.
