I've read many threads regarding pc won't boot after adding RAM, my case is also like this and even worse, i can't get my pc showing the BIOS bootup as in nothing at all. i've interchanged 1st RAM into the 2nd slot, sitting the new RAM on the 1st slot (2RAMs sitted) and vice versa; trying only 1 RAM at a time on the 2 two slots; putting the original RAM that came with my PC back into the slot, still, nothing shows. i can't press delete or F8 or F10, etc....are my RAMs burnt out? how can u tell? i didn't see any signs of burnt chip on my RAM, Please help....
