Hi guys.. I'm not really all that great with hardware but I think I know most of the basics. I have a 2nd comp that I figured I would start using again and dust collected inside all over. I took the video card out, ram out, fan out, and I cleaned all over the whole comp. I used one of those hand compressed air things. Now that I popped back in the ram and all the other parts my computer doesn't work. Isn't that great? I'm thinking that I didn't pop the ram in the correct direction or way. When I turn the comp on my screen doesn't re-act and my computer just keeps beeping? Any ideas guys? Also where can I can some safty things like an antistatic wrist strap. Something cheap please.
