I opened my pc's bios setup a few days ago. I changed some settings (which were related to graphics) . It was somewhat of a graphic card selection. I changed it from auto to pci express---. I saved the settings and again started the system. But now what it does is that it starts and shuts down automatically (and this process never stops). What should i do now? Here are my system specs processor- intel core 2 duo E7500@ 2.93GHz ram- 512 mb graphics- intel gma x4500 (maybe)
