Slow to Fast

[aj350z]

For a couple of days my power has been going off and my Mac Pro has unfortunately been shutting off. Every time i turn it back on, im noticing how slow it is to start. I open up mail, safari, and itunes and they load up slow. But if i wait about 30 mins they will all load up quick. I have the 2.8 Ghz Quad core with 2GB of ram. Should i just go to 4GB or 6BG of ram or do you think it is something else?

Also where can i buy cheap (cheaper then apple) quality ram?

Thanks

I don't think it is the RAM...but other than that i have no clue.

Don't worry about it, each time your restarting the MP the apps have to re-cache so it takes that little bit longer, after that your away, 2GB is fine for mail,browsing and itunes stuff, if your using photoshop consider using a scratch disk, but if you do have a few memory hungry apps it wouldn't hurt upping it to 4gb
