1st and foremost i'm not too familiar with the internal workings of computers :(. The problem i'm having with my Compaq desktop computer is the orange light on the front comes on and stays on as soon as i push the power. No green light at all. My HD isn't spinning either and there are no beeps. I used different psus which were 50 watts lower(all i could find) to check if that was the cause, no luck. When I connected a smaller HD than the 1 I have, it spun up. The green light on the back of the psu comes on as well and the fan to the ps and processor work. It's driving me insane trying to figure out the cause, thats why im here. ANY possible solutions would be GREATLY appreciated!
