Format C²

Hey guys,
I know you're terribly in trouble since you havent seen me on LoL neither on RTCW:ET for a couple of days now.

I was suprised to see how helpful CF computer geez are. Yo guys are wery kewl!
I had some tips from Farmer Hukk but you maybe have easier solutions for me.

Well I tried to format and I forgot a detail... I changed my motherboard 2 years ago LOL

I found my vista DVD back but I can't install it because its OEM version you know shit provided with pc. I had Acer motherboard and I now have MSI (got drivers). I tried to reinstall it but it seems like something goes wrong vista loads for 0.00000001337secs and then BLUE SCREEN + restart

Got linux still working though.

What should I do to get my vista back (got license key)?

I went to the repairing store they want 60€ to fix it. Should I accept?

Thanks in advance,

LeFrancis. -
