Windows 7: Two issues: Upgrade install of W7x86 fails and W7x64 fails to clean install

Two issues: Upgrade install of W7x86 fails and W7x64 fails to clean install

Clean installing Windows 7 x86 is no problem. But
1) upgrading Vista x86 to Windows 7 x86 fails and automatically rolls back to Vista, and
2) attempt to clean install Windows 7 x64 results in BSOD when rebooting to finalize the process.
Any suggestion would be appreciated.

Hi churin and welcome to Windows 7 Forums

I would actually never contemplate on upgrading one OS to another - a clean install is by far the best way to go. True, installing the upgrade version of Vista as a clean install means that you actually install Vista twice, once on an empty drive/partition and then as an upgrade over itself, but it is the same OS. I would expect that the same (or similar) procedure would be true for Windows 7. This could explain your first problem.
As for your second problem, it is possible that your download is corrupted for some reason or other. You could try downloading it again to see if that is the problem.

Windows 7 Ultimate Vista Ultimate x64

If you have any overclocks it's good to restore defaults plus sometimes if you have more than 2gigs of RAM when installing can cause problems with BSOD's as well so you could try taking a stick out and see how it goes, I had to do that with Vista once but I haven't had that problem with Windows 7, although I do have another problem with installing 7 on my Evga 750i FTW motherboard in combination with GTX260 video card.

I get to the finalizing part where the screen goes off for a couple of seconds to install the graphics driver but for some reason I had problems with it coming back on. the only way I got around it last time was to change the card to my old 8600GT while installing.

Dwarf and Mr. GRiM, thanks for your responses.
I decided to try removing one of the two RAM sticks as a starter. Bingo, it worked.
I had the same problem installing Vista x64 and Windows 2008 x64, so I am going try them again.
Thanks again.
