I am running an Intel Celeron E3200 dual core CPU on Intel DG43GT motherboard. I just need to know if Windows 7 64 bit is compatible. I believe it is but I want to be sure before I install!! Thanks for the help!!
According to Intel's supported operating system list, your DG43GT is supported to run Win 7 32 bit and 64 bit: http://www.intel.com/support/motherboards/desktop/sb/cs-008326.htm
Your processor is also showing as being supported under several revisions of your motherboard providing you have BIOS revision 0028 installed or newer: http://processormatch.intel.com/CompDB/SearchResult.aspx?Boardname=DG43GT the support website tells you how to check your board revision or Intel Desktop Utilities does this (on supported boards).
