Reply to Slipstreamed windows ISOs optimized for djing ?

Hello there, i've been having problems with my laptop ever since i bought a brand new hdd and installed a fresh copy of windows 7.
Waveforms are sluggish in both serato and traktor (vdj works fine tho), and traktor is MIGHTY slow. It takes about 10 seconds to get into the settings menu, let alone browsing and loading tracks.
Serato also crashes when i load some of the tracks, and i have these weird cpu spikes when doing absolutely nothing.

My specs are: quadcore i7 (2ndgen) @2ghz, 8gb ram @1333, WD caviar black 7200rpm 750gb, nvidia gt540m 2gb.
OS: Win7 Ultimate x64 (genuine), followed every optimization guide out there.
The disk is defragmented every week by a good third party defragger, i have about 180gb used on the disk, now this is only music, on the laptop i have installed just serato, traktor, vdj, chrome, itunes and the defragger. NOTHING ELSE.


TL;DR
So if any of you know of any slipstreamed installs of windows 7 that are specifically targeted at and optimized for music production/djing, that would be GREAT.


Thank you
Luka
