Oh jolly justice, everything is fixed and functioning now, ran one more wipeout and refreshing install with the right order of discs this time, installed everything again, installed a little more, did a little bit of everything, and my PC is once again working better than ever. Next step, buy a 750GB external drive before summer and secure copies of all files available. Now, studies are waiting for me . . .
If you have XP yet feel the need for some fresh newsense, go get: winflip (gives you a 3d window view thing), Razor 2 (black win7-ish theme, very nice) & the Windows 7 fonts & icons (just Google that). Made a selfinstalling package of them myself, and a dussin other newly downloaded apps incase my computer once again on a rare occasion decides to crash on me.
