Question about E-Machines -T1840-CELERON-1.8GHz,40GB Desktop Computer System (1000000127)
Hate to say it. But down at my shop, we have repaired a good 200+ eMachines in the last two years... all with the same ailments.
Usually what we find, is a bad power supply. That's only the first part.... in most cases the mainboard is damaged as well and needs to be replaced.
If you look at your power supply, it is probably a Bestec brand. While you have the cover off, look over the mainboard with a flashlight. You may find a blown ITE chip, or even some hot spots or small burn spots on the southbridge chip. Which is located usually towards the bottom right side of the board if your point of view is with the computer sitting upright. It will be about one inch square in size.
If you have a space power supply, or know someone with one, you can try that. We've not had much luck replacing just the power supply. In a few rare cases it solved the problem. But in most, a motherboard replacement was in order as well.
Best we can figure, the power supply fails and takes the mainboard with it. The only commonality among each one, was the Bestec power supply. Since some of these were Intel based and some were AMD based.
