Ok, heres my situation. I have a 3 year old HP computer with 504mb ram, 40gb HD, 2.4 ghz processor, 64mb video card. Would it be possible at all to upgrade my ram up to 1gig or 2gig and would it be possible to upgrade the video card to either 256 or 512mb? Im just curious if my computer would freak out from all the power going into, or would it reject that much power or anything?
