Sogi-Ya: good for you, the rest of us mere mortals typically didn't have access to the resources necessary to construct our own PCs :P I just did a clean install, copied what files I didn't want to loose to my secondary hard drive and let the rest go. whoever says that Win 7 is the most stable thing ever is so full of shit their eyes are brown, I had two blue screens and three hard locks during the process of updating off of MS update.
Why? You lived in some backwater place? I mean, if I was able to do it, in a shitty little country I imagine somebody from the mighty US could do it a million times easier.
Windows 7 is a pinnacle of operating systems made by MS. If you had any problems with blue screens that means you are using incompatible hardware, maybe upgrade that SCSI card you have from your win xp days? :P
Also, next time maybe you'd like to build your own rig which will work perfectly instead of pouring your money into some incompetent store which makes generic pcs and sells them like "hardcore gaming rigs" lol.
Or buy a mac? Seems like a perfect computer for you :)
