overclocking and windows performance

[hardc0re_tid]

ive had my 6300 at 2.8 (stable btw) for ages now and half the time when i click the start button in windows it takes a second or two for the menu to appear.

ive also noticed other things 'lag' such as the time taken for winamp to start playing a song - id double click the song and it would take a moment for winamp to appear and start playing, this is with nothing else running, windows is sitting idle

another thing is the time taken to display the icons in my computer - no very often though. its seems to be happening more recently now. i installed xp pro sp2 early jan iirc and use diskeeper to defrag and ccleaner to clean up files and the reg.

im almost certain that none of this happen when i was running at stock 1.86

could my oc be affecting performance. it plays games very very well with no stuttering, just seems general usage in windows.

i have a single 80GB WD CavierSE (i dont think its sata 2) for windows

and 2 250GB Seagates 7200.10's which are def sata 2, D & E, D is for games and E is for music and video.

i have my pcie freqency set to 110 in the BIOS to make my 7900gto work properly (although it takes a restart for it to be seen as x16 or else it will run in x1 mode - stupid P5B Deluxe) i have heard that around 120mhz will affect the sata drives.

system specs are

e6300 at 2.8ghz (400x7)
2gb geil 6400 ull at default speeds - 800mhz
asus p5b deluxe with 1004 bios
7900gto at stock - was at 700/800
pci audigy 2 5.1
1 wd 80gb for windows
1 seagate 7200.10 for games
1 seagate 7200.10 for music and video etc
