My computer specs

[DeathsHand]

P4 3Ghz
512MB Ram
110GB (apparently? Seems like an odd number for a HD)
ATI Radeon 9800 Pro
and some on-board sound card...

I been thinkin lately of upgrading either another 512ram, or another gig of ram... Everything else seems rather adequate for now! My problem is system cooling... Which I know nothing about... After I put the new graphics card in it started actin up what with heating and all... I just keep the side of the case off...
