Question about Dell Dimension 5100 (D51L1) PC Desktop
Hi, there, any expert:
I have listed my threads under my name Jayjin below the line. Now I had formated the C drive, removed the Vista, and reinstalled the XP OS the night before yesterday, and we could shut down and reboot over and over again, finishing all the necessary installations of software.
But yesterday, my son booted up the Dell, then shut it down, when I got home, I could not reboot the Dell. So I am very very frustrated! The Vista or XP OS seems not an issue here, but why it can't boot up from a hot machine until a second day when the machine is cool and clears all the memory?
The Dell 5100 doesn't give a blue screen, or any green light (1,2,3,4), it either remains dead (with green light on Mobo), or it can reboot up with full functions.
Please give me suggestions, what is wrong. Thanks a million in advance.

My son powered off the Dell 5100 by the push button which was absolutely normal, and it now can't power up. The green LED is lit on the motherboard. Green light on motherboard works. Just a little over 3 years old and out of warranty. I replaced the power cord and used another power extension cord. Problem remains the same.
Give me hints. Thank you a million.

Pagebor; Thank you for help. Yesterday afternoon the Dell 5100 booted up and everything returned to normal. I told my son if he shut it down, it would not reboot. And it was true.
I searched if any capacitor has visual breakdown. It doesn't have. I toggled the 115/230v switch, and removed the mobo battery and put it back, it just can't reboot.
I told to my son, if you turn on the next day (i.e. today), it would reboot and be normal.
This problem happened one or two days after my son upgraded the Dell 5100 from XP to Vista Ultimate and with the help of Microsoft Assitance installed the SP1. Then the non-boot problem kicked in. Before he installed the Vista, Microsfot check says it is barely compatible, while Dell check says the Dimension 5100 is not compatible for Vista at all.
Today we will format the C drive if it can be rebooted, and then reveret it to its original XP.
If I am right, then, the Vista Ultimate is causing the problem, in flooding the Cache, jamming the RAM etc. Once a day's time clears all its content, the system can reboot itself. We'll see.
Any suggestion? and tell me why this is happening?
Thank you in advance!

After we formated the C drive, removing Vista, and reinstalled XP, now the Dell Dimension 5100 returned to normal. It just doesn't have any hardware problem, such as mobo, PSU or RAM.
I had same issue with dimension 5100 Desktop. I work at Circuit City as the Lead Technician. I found that swapping the power supply did fix the problem! When i initially tested the power supply with a standard power supply tester, the power supply appeared normal. But after swapping the PC works great. Thx for the good idea!

I have repaired this problem on over 2 dozen Dell Inspiron 5100 laptops with power or no boot problems. First make sure you have a 90 watt power supply NOT a 70 watt one. If you have a 70 watt one, get the bigger 90 watt supply cord, as the 70 watt ones were recalled due to being a fire hazard! This solved the issue more times than not.
Next often, it was the memory cards failing in such a way to drag down the bus and preventing the machine from completing the POST (Power On Self Test). Replace them in pairs. They usually fail at the same time. These are inserted at a slight upward angle into the slots, seated, then pushed down and locked in by the two side tabs.
This will solve 90% of all such problems with the Dell Inspiron laptops. (notorious for power problems, get the 90 watt supply!)
Third often, it was a combination of the two above mentioned problems.
