I would consider myself to be of intermediate level in terms of computer expertise. I built my own pc, running a 2.66 intel quad core extreme on a intel extreme motherboard. When adjusting the BIOS i changed the settings of the RAM for which i thought I was correcting the configuration speed to 1333 mhz (from 1066) as i was postive that was the ddr3 RAM chips stated speed. When re-intialising the machine it fails to start properly, as the visual display is lost. Following intels BIOS restart by clearing the CMOS has not solved the problem. It appears I am out of my depth with this problem and am seeking advice from any expert that cares to lend it. cheers.
on initial boot tap the keys to enable safe mode usually F5 or F8, if you can get this select VGA mode. This will restore your BIOS to it's default settings and a very low screen resolution. Re-load the graphicss drivers and you should have a usuable machine. Terry
If you get nothing with the memory installed and you get a BIOS beep error with it removed then you may have fried the memory. Have you any other compatible memory you can try in it? Is it onboard graphics? Are you sure it was the RAM frquency you changed from 1066 to 1333? If it was the CPU then it would be fried as that would be toooo big a jump.
