Hi,

I have an old Dell Dimension 9150 that just stopped working a few days ago. When you turn the computer on, it would turn on for two ~ three seconds, and turn off. You could hear the fans going, but the machine would not post. On the front panel, where Dell has a 'diagnostic lights', it shows 1 & 4.

I went to Dell's support page and was unable to find what 1&4 lights mean. Curious if anyone else have similar problems?
