Need Help with my Computer

[FORSFED]

I don't know much when it comes to computers, so I thought I'd see if someone here could help me out. Everytime I go online I will get the blue screen of death. It used to happen instantly when I'd open Netscape, so I deleted it since I don't use it that often anyway. But I still get it even when using IE. Usually after about a good 15 - 20 mins or trying to open 3-4 pages at once, it'll pop up and tell me there's a Windows error at such and such location, blah blah blah, I don't know what it all means. Then after hitting enter the computer resets and it won't turn back on because the screen will reappear before loading my desktop and keep going through this endless loop. Sometimes it even shows some Spool 32 error in the middle of all of it. After letting it sit for 15 mins it'll start back up with no problems. Is this a memory problem, like I don't have enough? Anybody have any ideas? Thanks.
