Hi

Can anyone help my computer was working fine, exited a game it went black screen tried a reboot and since then the computer turns on all fans etc are running it makes all the sounds of booting up but there is nothing on my screen, I bought a new graphics card thinking my old one had died but again upon turning it on the pc has same issue the only other thing I can notice is upon powering on there are two beeps now I have an asrock motherboard upon googling two beeps equals a parity error, I have tried reseating the rams etc but still have the same issues is the two beeps telling me that both ram 4gb ddr3 chips are dead or any other info as to what the problem could be any help would be appreciated. Thanks, tom.

i had the same issue twice and both turned out to be a RAM failure.

try booting with your first ram,if you dont see any thing try booting with the second RAM.
this will help you figure out which RAM is faluty.

your computer will boot only if you have one working RAM stick or two working RAM stick.

it wont boot with 1stick(good) + 1stick(bad)..

Hi have tried that with no luck is it a possibility that both ram sticks have gone both 4gb sticks, if the motherboard was faulty would it be able to put out the beeps could the ram slot on the motherboard be broken, it is a asrock fm2a55m-dgs
