Windows 7 Ultimate x64 not opening any 32 bit programs

So far, iv tried fixing things with the Windows 7 install disk, and have run a ton of anti virus/malware/spyware stuff. They found nothing. I also cant restore to a earlier date. This all happened after some Oct 14th windows updates. From what I read, it does some stuff to your registry keys? Other than that, I have absolutly no idea. It wont even open x86 programs when its in a safe mode startup or during a clean boot. I also tried making a new user in case mine was curropted, but that didnt seem to do anything either. Would completly nuking my harddrive and reinstalling be my only option at this point?


I dont have a soundcard. I have a MA785GT-GT Gigabyte motherboard with onboard 7.1 surround. I tried to download the drivers for it, but I cant run that program either. I cant run anything thats not stricly a x64 program. Also, whenever I try to open a media file outside of a x64 program, I get a prompt that says Server Execution Failed. That only happens with media files

As a side note, If it is a registry foul-up that happened in the update, could registry reflection or redirection in the
WOW6432node do anything? Registry keys are confusing to me, could someone tell me anything about this?


If worst comes to worst ,what is the best way to go about formating a harddrive? I'v never had to do it before. I have Hiren's boot CD and that has a pretty agressive nuking program.Would that be the best way to go about it?

To format a harddrive you can use build in function in Windows.

But to reformat your system drive, you will need your Windows DVD/CD to do so. Or other bootable CD that can do formatting function.
