Can I swap from windows 7 64bit to a 32bit?

Hi  

No...

You NEED a 32 bit disc and a complete format...

All the best Brett  

I can not think of a good reason you would want to do that.... there is XP mode for older programs.

Because My PC reboots for no reason when I play games...And I was thinking that the cause could prob be Windows 64bit....The error is a kernel power error 41

I have gamed on Windows 7 Home Premium 64 bit since it came out in 2009 and have had minimal problems. A 32 bit OS will not support over 4 GB of RAM (the OS will indicated 3.25 GB... but whatever) If you have less than 4 GB of RAM, it is likely you would see a small performance increase downgrading to a 32 bit OS, but other than that... you really shouldn't be considering it. My guess is that you have some sort of other problem... either thermal or power related... and that's what is contributing to your instability.

There is no reason to think that your 64 bit version is causing the error, maybe is some driver or some corrupted file.

Formating should solve the problem, BUT before that I recommend that you take as much info as you can of that BSOD and search the internet for that particular error

This ERROR usually indicates a problem with the hardware not the OS.
