Hey guys I'm having some troubles with my pc after trying to install some ram. I have AsRock M3A770DE, and phenom ii x4 955. The computer had 4 sticks of 2 gb xms3 ddr3. A friend gave me 2 sticks of corsair vengeance 8 gb ddr3. I checked compatibility and it seemed like i could replace all 4 sticks and with just the 2 sticks of corsair vengeance, so i did. At first attempt to boot, the monitor read no signal, so i reseated the ram more firmly, and booted up again. I made it to the black screen where it tells you to select which method of boot up i wanted and could not select with enter so I waited for it to auto select regular boot up. It did and I was able to type my password to log in, also i might be important to note my keyboard was plugged into a ps2 port.
Here is where the problem arose. I was not able to use my keyboard or mouse after coming to the desktop. So i rebooted, and everything went the same. I tried installing the 4 sticks of 2gb Ram again, and the same thing happened, so i tried installing just 2 sticks of 2 gb ram, and then could not even type in my password at the log-in screen. I tried plugging my keyboard into a usb port, rather than ps2 and the win/lock and cap/lock keys led lights were both lighted up even though my pc was shutdown. I tried installing the 8gb sticks again and booted up and was not able to even type in my password, so seeing as the problem was growing worse i ran onto these forums to try and revert any damage i may have done to my pc.
Also this was my first time installing ram in 4 years and though i watched a video do not count out anything as being too obvious for me not to do it.
