Does a 64 bit OS generate more heat than a 32 bit OS on the same machine?

Hi All,

My friend’s Acer Aspire 5100 LT failed not long after I set it up with a fresh 64 bit Win7 install. It ran fine for years with 32 bit Vista on it. Coincidence, or does a 64 bit OS run hotter than 32 bit on the same CPU, therefore over-taxing the older MB and\or other components?Thanks,

Gary

Well, a 64-bit OS does support more memory and hence can contribute to heat, but I don't think that 64-bit vs. 32-bit should raise any problems with heat.  I would look more towards possible hardware incompatibility between the 32/64-bit architecture.

Hmmm. I bet you're on to something. Do you see that as something that would cause a catastrophic failure?  Why would Acer put a 64 bit processor in something that can't support it otherwise?

Well it may not be the processor.  It might be another component that doesn't like either Windows 7 or a 64-bit or both...but if you want to check the temperatures, download this program:

And watch the temperatures as you work on the computer.  And listen for or feel if the fan is working.

Also, to answer your question, Acer is a company that makes hundreds of consumer goods and sells it across the globe.  They may list Windows 7 compatibility but may not have the means to fully test their claims.  Anyways, it doesn't mean that 7 wont work with your computer, lets first conclude what's causing the problem.

frabus: At this point, probably. You may try disconnecting power and pulling the battery for 60 seconds, but if that doesn't make it POST, it's dead, Jim.

All of which means nothing, because parts fail as time goes on, and the probability increases with age.  What you saw was just a concidence - past history is no indication of it continuing to work normally.
