Thanks for joining the Chipset community.
I understand you have an Intel motherboard and you are experiencing some restart issues under win7 and XP.
It would be very helpful if you could include more detailed information about the problem you are experiencing. Please include any error messages that you might be getting and any steps you have performed to solve it.
Also, provide the Intel motherboard model number and the processor model.
Pleased to get your reply. No error messages the windows is giving at all. Whenever I use to play a game/use the software like GoogleEarth that renders graphic memory my system get a restart suddenly without giving any warning.
I have addressed this problem to my technician, he diagnosed my system and asked me to use external graphic adapter instead. Unfortunately the adapter was not available in the market.
Model number is 88089HU and processor is Intel Core2 CPU 4300 @1.80Ghz, 2400Mhz 2Cores.
At this stage, make sure you have updated video drivers here: Intel® Download Center
Please filter by operating system and try to install the driver when it finishes downloading, to verify that your system will accept it.
Also, check with Home - Lenovo Support (US) for information about the type of external video cards that are compatible for your system model.
