Hi, 2 months ago i have encountered that only 1 (out of 2) cores were working on my processor (Intel® Core™2 Duo Processor E7200 2.53ghz) . i tried every thing (checked through cpu-z, core-temp and task manager) but they showed only one core.Multi core processing is enabled in bios. i also tried Msconfig.exe method but its drop down list also showed only one core.. So after all that mess someone told me to reinstall windows, so about a month ago i reinstalled the window and both cores started working fine but the next day when i turned on the PC again only one core was working.. After that someone told me that my PSU is weak and gives less voltage therefore the motherboard automatically turns off one core to prevent any other damage. So last week i bought a new PSU (powerful one) but still no cores worked. Yesterday i bought a new processor (Intel® Core™2 Duo Processor E8600 3.33ghz) and swapped it into a cpu but unluckily again the one core didn't not worked. recently i re-installed windows and both cores again worked perfectly but after a restart 1 core was again down.... so i figured out that in device manager i am seeing only a single processor so i un-installed that processor's driver and restarted the pc and then both cores again started to work and device manager also shows 2 processors but now after every shutdown, whenever i turn on my pc again it runs on single core and everytime to make it work on 2 cores i have to uninstall the old drivers and install the new ones for processor,,, so please tell me how to fix this problem?? any solution will be much appreciated..
