It's not the operating system that's the problem. Windows 7 automatically shifts into 32-bit mode when you run a 32-bit program on it.
The challenge is that the 64-bit drivers aren't yet fully compatible -- and that's causing a lot of people problems.
So, at this time, I wouldn't recommend Premiere Elements 8 on Windows 7 64-bit (although it runs very well on Windows 7 32-bit with adequate hardware support). Premiere Elements 7 seems to run a bit better on it, but even then you may be in untested waters.
I'd try the free trial first and see what my personal results were.

Its getting harder to find the PRE7 trial but this link looks to be working:

i downloaded the PE8 trial and have worked with it for a couple of hours and had only one glitch so far. while capturing it froze after about 10 minutes, i had to capture the rest and splice it in. i added some titles and a 2nd audio track that was mono and used audio effects to copy left track to right track, i faded in video and audio and so far everything seems to be working fine.
i have an intel MB D975XBX2
dual core processor,
4 gigs of RAM
win7 pro 64bit
it's taking a little getting used to but probably not as hard as trying to learn a whole other program like sony studio for example. i've got 30 days and i'll keep using it and see how it goes but so far, so good.
I was running both PE7 and Pinnacle Studio 12 on a Vista 64 laptop with a measly graphics card. They both worked fine although a bit slow and sometimes the output quality wasn't so good. The output quality proceeded to get worse. I could deal with the speed issue but not the quality issue.
I bought a desktop win7 64 with an i7 8gb of ram and a 512mb quadro graphics card. It should blow the bleepin doors off of PE. I bought this pc with the future in mind and only because a comparable Mac pro was so much more expensive. I should have known better that the software quality and consistency on the PC platform is so bad. Factoring in that I might have to plunk down for Premiere Pro (who knows if that will even work), The Mac and iLife would have been a better deal.
PRE8 on Win7 64 doesn't work at all for me on the new machine. After loading it and performing a few simple operations, it crashes and has to close. making matters worse, it isn't certain if I shell out even more money for Premiere Pro that it will make any difference.
I am having a little better luck with the Pinnacle product on Win7 but the rendering time is still the same as on my old laptop.
I wonder if the experts on here think reverting to Windows XP would solve a lot of these problems considering the hardware upgrades.
Welcome to the forum.
I would start with full details of the Assets, and even more info on your computer, such as the I/O sub-system, i.e. your HDD's, their size, speed, free space and how they are allocated.
Those will be good places to start to diagnose your issues. Without such info, it is all just guessing.
Good luck, and we'll be looking for the info.
