I'm very new to building computers and decided to try my hand at making a tower. Everything went well until it needed to be cleaned. I opened the case and after clearing out all the dust, various animal fur tufts and cigarette/ash residue off of my ram, started it up. The monitor is blank as if nothing is connected and about 2 seconds after being turned on, three .5 second beeps are heard. Thinking my ram was shocked, i bought two more sticks and when they were replaced and shuffled around into new docks as well, the same problem still occurred. Could i have possibly done something to my motherboard as well?
