I have had my father's 10 yr old computer to upgrade the memory (to the max 750mb) and to add a 2.0 usb adapter card. I also dusted it out with the air can thing following the directions so that I don't freeze any components.
I didn't turn it on after the upgrade to check it out because it was too late. I just now tried it and it looks like it wants to turn on (processor fan goes on and the power supply fan goes on but not the other fan at the bottom front of the chassis (bottom right in the picture). it runs for about one second. Also, the power light and hard drive light comes on during this one second.
I don't know what to try first to diagnose. Is it maybe the memory or usb I installed? Did I short-circuit something? I have no clue where to start with this problem. I can't afford to purchase a new system
I included pictures to show what the computer looks like. It's a Cybermax computer...don't have much other specs right now.
Assistance with this would be greatly appreciated!
