Windows 7 Professional SP1 clean install CPU 100% spike
I have read similliar threads on this forum but have found no solution to my problem.
I recently installed Windows 7 Professional SP1 x64 on a computer I had previously running 32bit version of windows 7. I deleted the existing partitions and create new one, but after instalation completes i get 100% usage of CPU. It isnt always the same process that hogs the computer, it is usually currently active application.
Since the computer worked fine under 32bit system and i primarily installed the 64bit version only to utilise the full capacity of 4GB ram that is installed, my first thought was that the processor doesn't support 64bit technology. So i checked the Intel's site where it says CPU supports 64bits.
I would really appreciate all the help i get.
The computer specs:
Intel Core2 Duo E7500
4GB Kingston Ram
ATI Radeon Graphics
