SOURCE: Change Motherboard For Dell Dimension 5150
If you replace with the same motherboard that's in already, that would be easiest for you.
But if you use a different one, you'll have to re-activate Windows, and download and install new device drivers.

Hi, maybe he was over heating, open your tower and look the fan of your CPU and POWER SUPPLY. Did they work? If yes, did the dirt on the heatsink of the cpu hide the heatsink? If yes clean it and make a test!

That flashing amber light is usually a sign the power supply is failed
or is failing. I would suspect the
power supply is the problem in yours. It is the better of the two problems connected with the flashing amber light..the other is motherboard is failing. Arrrr!
hope this helps (it takes a standard- oh say 350 watt 20-24 pin power supply unit.)
Hope an answer helps.
Please leave rating, thankyou

If you experience the dreaded blinking orange power light, make sure to check your motherboard for blown capacitors as well as corrosion on the motherboard. Looks like the photo below.... if you see this then a replacement motherboard is needed.

I have similar problem these days. After normal shutting down the PC, it can not be powered up again, the amber light blinks. A temp solution for my case is by doing these steps:
1. leave all monitor, network, keyboard and mouse etc. connected
2. disconnect the power, wait until green light and amber light dim.
3. pop up the CMOS battery, then put back in (better to check its remaining voltage, if not good, change a new one)
4. power amber light flash shorter and lighter
5. disconnect any USB connections like keyboard and mouse,
6. immediately connect keyboard and mouse back into USB ports
7. my pc powers up at this point, all green lights shining. Except it displays CMOS setup warnings, give me options to click either F1 or F2
8. I click F1, it goes into normal login XP
The only problem is I could not shutdown PC again, if I do, then I have to repeat 1-8. I have to use "Standby" instead, which I usually do.
