Question about Dell Dimension 5150 (DIM515MIN) PC Desktop

3 Answers

Dell Dimension 5150 starts up on its own!!

I'm having a bunch of issues with my Dell, re. startup and shutdown.

It started with it booting up on its own from switched off. I don't have wake on LAN or wake on USB enabled - it just does it.

Then, just yesterday it started booting up on its own and immediately shutting down after a couple of seconds. Finally, it shut down and wouldn't restart. A long hard push of the on/off button would fire it up but it would shut down again after a couple of seconds. Fans kick in and HD whirrs but only briefly.

I opened the case and gave everything a clean but it didn't help. Then I went out and when I came back it had started up fully and was working fine. :$

The system is obviously shaky. Any ideas?

    I changed power supply, power cable and power strip - still same problem. And then...

    I took the side off and had a root around. I disconnected the ribbon cable from the power button panel to the mobo. When switched on at mains, the PC booted right up. Of course, with the power button disabled, I can't switch it on when powered down, nor can I use the two USB ports at the front. But it has shown the nub of the problem.

    I have almost the same problem. I completely removed the front panel, which includes the power switch and the usb ports. I just connect the panel for less than a second. I push the button on and immediately remove it. The computer started to work. I worked for more than a month with no problems. then the same started to happen again: it works for a few minutes and just turns off. sometimes it can be booted again and sometimes not. looks like a heat thing but the fan works well. any suggestions.

Hi All,

I had the same problem - shutting and restarting over and over again. When called Dell, they said it is most likely the motherboard and will need changing. I personally suspected that it has something to do with the power supply.

I was right. I replaced the 305W power supply with a 370W one. Problem solved with just £25 and a trip to Maplin.

Let me know if this helps.

I had the same problem, tried changing the PSU but no change and the old PSU checked out fine on a power test unit.

Turned out to be the switch panel with USB and audio connectors being defective. Try changing this and you should be OK

Check the power cable for some defect. It may have been twisted and the wires inside broken. Try using an alternate power cable and see how it goes.

Dell dimension 5150. wont start


Most times when you have flashing yellow light there is issue ether with cpu or motherboard. Just to be safe test the power supply and if ok then try to replace cpu and go from there. If power supply issue just replace it. Might be easier to take it to pc repair store. Good Luck

Dell Dimension 4600 will not reboot. I have to turn it off, unplug the power, push the On/off switch for a moment, let it set for 15 min then it will reboot. I have recently upgraded from 256kb ram to 1gb,...


from what you describe, they system will not shutdown. So try the following:
  1. Boot to safe mode (F8 at boot) and then see if the system will reboot from the safe mode.
  2. Boot to the Safe Mode again, Start RUN MSCONFIG, edit the startup group, (Basically uncheck all the items in the startup tab) reboot in the normal mode then see if it shutsdown. If it shutsdown normally, then start adding items back one at a time until you identify the items that were causing the items.

Dell Dimension 5150 will not start!


This is related to Hardware.

There might be a lose Ram of data cable connection on Motherboard.

This type of issue is also seen when the there is dust accumulation on Process Fan and CPU fan resulting in over heating.

This might also be due to malfunction of a motherboard.

The third reason could be that SMPS his not working.

My 5150 is not booting


sounds as if you have a hard drive issue and i would start there first by seeing if you can connect the hard drive to another pc and pull it up if you can than you have other issues

Dell Dimension 5150 no sound - please help


You should be able to download the original driver files from Dell Support Drivers & Downloads.

However, this may be worth a try:
Go to Start --> Run, and type in services.msc.

A window will pop up with a list of services. Scroll down to Windows Audio. Right-click
and click on Properties.
Make sure that "Startup type" is set to automatic. Also, make sure, under "Service
status," start is selected.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
