Today when I wanted to start my Dell Dimension 9200, it didn't. All that happenend was that an orange light kept blinking on the front. As far as I've gathered from various forums, it seems to be the power supply most likely. The thing is, I have another older Dell (Dimension 9100) from 2005 sitting around and I was wondereing if I could just exchange the power supplys to test if thats the problem. As far as I can tell, there isn't much of a difference between the two PSUs, one being called L375P-00 (the new one from 2007) and the old one is N375P-00. Anyone know if I can trade these parts without risk? If you want, I can give you more data on what the stickers on the PSUs say. Thanks!
