Windows 7: Windows 7 Ultimate x64 bit installation problem

Hello.

As you allready know, I got a installation problem. I recently bought Windows 7 Ultimate x64 setup because I wanted to extend my computer performace even further. I had a Windows vista Ultimate x32 bit system..
I downloaded Windows 7 Upgrade advisor and my computer was able to use x64 bit.

So I ran the installation and I chose custom installation because I wanted to delete all my files on my computer. Everything went fine untill the the first reboot. It rebooted and after the "Windows is Starting" the BLUE SCREEN OF DEATH poped up and said it there was a system problem etc.. I can't really remember the problem but it was something with 0x0000007 i think. I forgot to write it on a paper.

So I went back to the store and bought a Windows 7 Ultimate x32 bit. I installed it and everything just fine. I'm currently using windows 7 32bit, but I reaaaalllyyyyy want to use the 64bit!!

help?

I'm really sorry for not providing any picture of the problem.

Hi and welcome.
Interesting problem. The only thing I would suggest is to reduce down to 4 Gig of RAM on in the initial install 64bit unstall. If this works out and you update your motherboard drivers as well as the other hardware drivers then try reinstalling the additional RAM.

This is just my idea of what I would do.
Let us know what happens.

See if your SATA controller is set to ACHI in BIOS setup. Try that first, then IDE mode.

Did you run the Windows 7 Upgrade Advisor ?

Thank you guys for responding.
