@Slim142:
Looks like system files scan ( sfc ) @ Windows XP isn't really good to tell if we have corruption or not, because it looks like it asks for the windows disc even when there's no corruption ( just tested it on my P5K3 Deluxe ). [ probably checks the files not only from the "backup repository" on the HDD, but from your windows disc as well, that's why it's asking for it every now and then ].

So, unless you're having silly crashes ( like crashing while idling in Crysis main menu ) you shall be fine.

p.s. The white memory slots are clocking higher than the blue ones.
