Hi,
I have searched alot and didn't find a solution to my problem
Trials:
- Performed Clean Boot
- Disabled Intel SpeedStep
- Disabled NVIDIA PowerMizer
- Changed Windows Power Options (High Performance)
- Tried latest graphics card NVIDIA drivers, as well as OEM DELL driver
- Tried clean install of Windows 7 x64 and x86 and install only NVIDIA driver and Intel Chipset
- Disabled Network/Wireless/USB and most of the devices leaving only necessary ones
I have been running Win7 smoothly for a year and this issue occurred suddenly
The problem occurs when playing a 3D game where the CPU clock suddenly drop to 400MHz. After reboot the CPU clock is back to 2.2GHz, after starting a 2D game like (GTA2) or 3D game like (StarCraft2) it is a few seconds and the CPU clock is down to 400Mhz again and nothing fix it but only reboot !
Note: my CPU is running at temperature 40C~50C while the maximum according to Intel is 100C
My Specs are: Dell Inspiron 1520 Core2Duo T7500, 2G DDR2, NVIDIA 8600MGT 256M, Win 7 x86 and x64
