hey, im new to these forms and it looked like you ladies and gentlemen most likely know enough to at least lend me a hand... i recently bought some ram to upgrade my computer, i use to have 1gb of ram,(2 sticks of 512). the ram was 184 pin ddr dual channel ram. the new ram i bought was very similar if not exactly the same (184 pin ddr, 400mhz) 2 sticks of 512. when i installed it, the computer started up and then went to the dos startup screen, where it stayed for about two minutes longer than it usually does. it then went to a BIOS screen asking me to tell it where to boot up from. when i tired to move the cursor down to select my hard drive, my keyboard was not responding, so i turned my computer off to restart it. however, when i tried to restart my computer, it does not turn on. all my fans do and all the lights on the mobo and such come on, but the computer never starts up. the screen never comes on and there is no sign that the computer is trying to do anything. any help anyone could give me would be fantastic. thanks!
