Hello guys. I just got my Windows 7 copy from Amazon and happily proceeded to perform a clean install. Happily my ass. Anyway, everything went fine, I formated my hard drive and hit the install button. Extracting and all that went fine, at one point it required a reboot and did so. After the reboot it started working on the "Completing Installation"-step, and it's been doing that since. (For two-three hours now.) The dots are still moving, but it seems as if they're lagging, as if the computer freezes for ten seconds then work for a few, and freezes again. It's like one dot > ten seconds > two dots > three > 10 seconds > one dot > 10 seconds > two > three. (Also at this point, if I move my mouse, the cursor won't move, and suddenly "jump" to a spot on the screen during the "unfreeze"-period.) I'm gonna keep waiting as it seems if the installation is moving albeit -very- slow, but this is somewhat annoying. No wait, disregard that, it's incredibly annoying. It's a Home-version ordered from Amazon.co.uk and the DVD looks just fine. I've installed Vista on my computer numerous of times with no issues at all. Some quick computer specs.

I'm pretty certain that all of my computer hardware should be compatible with 64-bit, but I might be wrong. I've also pretty much concluded with the fact that the 9-series of nVidia is causing a lot of problems. I'll come back to you with additional information later today. Gonna let it work for a couple of hours more, but I'm already considering reinstalling my old 32 bit Vista. And here I was looking forward to getting my Windows 7..
