I bought 8 gigs of ddr 3 ram after scanning my computer on crucial.com to find the right kind. After installing i tried to boot the computer but it would only turn on all the fans would run and after maybe 25 or 30 seconds it would shut off and then turn back on and repeat. I tried with just the new ram same thing. Then I put the old ram back in same result. I have no clue what could be causing the issue I built the PC in may and have not had a bit of a problem till now. Any help that can be given would be much appreciated.
