Well i have had this computer for about 5 years and have had many problems but i have come over then all. but now i seem to have reached a place i cannot fix. I have a Dell 8100 and i recently took some thing out and just dusted them off because of all the dust on them. and now when i start up the computer it does not seem to want to do anything. it turns on and the light is orange. and the like loading thing right under the power is just staying on for about 30 sec and then turns off. It will open the cd drives and when i put a cd in it will show it as reading it. but when i plug in a moniter or mouse or keyboard nothing happens. I did take off the green thing inside the computer by the cpu. But the things i took of to dust are the cpu, thing on top of the cpu, cpu fan, and some thing next to the cpu. i did not know what this part was so i looked up the model # on the dell site and it said "this product does not exsit", i also went to the site that makes the part and they do now have it either. but here is a pic of the inside of a comp that looks the same as mine except for the graphics card which is better then mine in the pic. i circled the things i took out of my comp. Does anyone know how i can fix this or why this happend?
