Help! My PC keep restart again and again, what happen?

I already re-formated the hardisk and succesful installed Win XP, I can see the Windows startup page, but then keep restart again and again.

Please HELP!

System:

Processor: Quad E9300 2.5Ghz

Motherboard: Gigabyte EP35-DS3P

Memory: Kingston 2GB X 2dimm

power supply: Acbel 660W

Display Card: Asus EN8800GT

Hardisk: Seagate 500GB

OS: Win XP Professional

try remove one RAM and start the system.

it works, thanks!

But when I install my "problem" ram to other PC, it's working fine, why?

it could be due to RAM speed not compatible.

the bus speed is determine by your processor bus speed. some times you can tweak the settings in the bios to set the speed slower.
