I am suffering from such a great problem that so much about processor and about motherboard. I have an old computer that has Intel E4800 @3.6GHz and has a Gigabyte GA-EP43-DS3L motherboard it was about 2 or 3 years ago but it works fine. But now days I have Intel i7 875K, motherboard Asus P7P55D-E Deluxe, RAM 2GB and have an ATI graphic card, this all smoothly work on Microsoft Windows 7 operating system. But recently this system is not working properly it get overclocked when I doing anything in high resolution. My aim is to achieve that CPU speed at 4GHz and memory to 2000MHz when I do this some error occur which not allow me to process system. So if you have any idea about this you can share with me.
