I turned off the power carefully opened up the case of a computer from a friend of the family, put in 512mb more of ddr ram to add to the 448 already in there. It beeped when I turned it on, so something was awry I turned it off again and tried again and the beep code went off again. So I said ok nvm then and I took out the ram I put in, now then I started up the computer and no beep code but also the monitor displays nothing. I dont see any fry marks or anything and im sure this computer uses ddr ram, I tried leaving the power off for a while. Oh yeah and before when I would start it up the fan was crazy loud, now its at a normal pace. There is a lot of dirt in there, I blowed it out with a household fan, considering taking a leaf blower to it, theres what almost looks like dried mud on the cpu fan. I am thinking of reseating everything, thats all I can think of hmm any thoughts?
