Ok so I just built a comp from the ground up for the fist time and I am having some serious problems. First, my setup : Gigabyte GA-P35-DS3L mobo,OCZ GameXStream 700w Crossfire PSU, Intel quad core Q9300 cpu, 8GB DDR2 667Mhz Samsung RAM(4x2GB sticks), 2 Samsung dvd+r DL Lightscribe drives, 500gb Samsung Sata hdd,512mb Nvidia GeForce Graphics card.I think that covers it. Here's the problem that I have been trying to fix for over a month. When I insert more than 2 sticks of ram in at a time the comp powers on but won't display any video and I get 3 short beeps and then a pause and then continous short beeps after that until I shut it down. If I boot up with 2 sticks of ram then it takes like three tries to get an OS installed but it will eventually install but get constant errors when trying to install or run programs. If I boot with just 1 stick then I can install an OS on the first try and get no errors when using the comp. Things I have tried: 3 different PSU's ranging from 400w to 700w, tried all sticks of ram one in at a time to make sure they work and all do and also tried all 4 ram slots and all seem to be working, I have disconnected everything but the bare minimum needed to install an OS, tried 2 different hdds, tried to install multiple 64bit OSes and all give me the same problems. I really need your guys' help! I absolutely have no ideas left as to why this is happening and it's really bumming me out cause it took me a long time to get the monmey to buy this stuff only to find out I suck. haha Thank you in advance for any help.
