Taking several minutes before I can use the computer

[Zezima]

So here it is, since a few weeks, I have to wait like 3-5 minutes before I can use my computer. It wasn't like this before.

I was thinking it may have to do with some virus. My brother was at a lanparty  (internet dwellers meet irl)some weeks ago, just before it started happening.

Weirdest thing is, if I use my computer before it's "done"(I can start FF or so, only some things don't work), I'll get a blue screen after like 10 minutes.

Uh oh how old is ur bro ?

About blue screen , my class mate had it hes into PC's and other crap , he loves PC's alot , but he didint identify the problem why he had a blue screen to , but as i remember i think he reinstaled windows and it was gone , or he had to bought one shity thing for his PC..Like change one part..
