Is my RAM dead?


Jan 21, 2012
hello everyone
i have a problem with my pc.
my pc is around 3 years old and it's configuration is:
Intel Core 2 Duo e7500 2.93 Ghz
Transcend 2 GB DDR2 667 Mhz ram
Intel DG41RQ
500 GB HDD
XFX 9400gt 1 GB DDR2

today, i tried to overclock my ram from 667 Mhz to 800 Mhz (using the BIOS). suddenly my monitor went blank. i tried restarting the pc but it had no effect. my pc is not booting anymore but the fans are spinning and the red led is on. i tried removing the battery and putting it back in, restoring bios to its default settings using the keys on the motherboard. i even tried removing the ram and putting it back into another slot correctly. but nothing happened. is my ram dead? or it's a problem with my motherboard?
