Out of memory error

[Azarathal]

Heya guys, playing games like Crysis2 and Civ5 the highest graphics settings and playing minecraft as it is cause me to keep getting out of memory errors that either crash the game or ask me to close them.

It's since I upgraded from a 4890hd to a 6950hd 2gb.

I've only got 4gb of ram but it isnt going anywhere near my physical limit nor is it filling my pagefile.

Help?

Minecraft is completely standard.

Forgot to mention I'm running 1920x1200 dvi-vga

Edit*
Turns out my computer had set my pagefile to 4mb >_< Now thats sorted.

Another problem is that despite being a i5 2500k @4.4ghz, 4gb 1600mhz 7-8-7-20 ram my computer's boot is stupidly slow, post takes 10-15seconds, booting from there takes about 10 but once it gets to "loading windows" it takes about 2minutes for everything to load.

I have 4gb ram, only about 2.5gb was in use, my page file was 4mb, now it's 4gb again.

Using x64 yeah

Marine I have a WD Green 7200 which was recommended by a member on another forum. Only got msn and CCC starting up.
