Dell Dimension 5100 - Will not turn on

I have a Dell Dimension 5100. This morning the tower would not turn on. I checked to make sure the surge protector was working and the power cord was connected properly. I cannot figure out why it would just not turn on.

I have a dell dimension desktop. It won't turn


open the tower//
check for any loose connection of the cord of Hard drive and power unit//
better option is take out the wires one-by-one and refix it//
if this does not work then probably the SMPS has gone bad and needs to be replaced..SMPS is the power unit which supplies power to all the component.
during all this process please alwaws make sure that when you put ur hand in the tower then the power cord should be out , otherwise you can get power shock.

Dell tower desktop Dimension 5100. Tower makes whistling sound.


sounds like it could be a bearing in your hard drive. is this problem constant? If so, I would open up the tower and disconnect the hard drive and then power up the tower again. if the sound goes away--you need to get a new hard drive. If not, you could have some dust bunnies in your cooling fan.

No power to Dell demension 5100 desktop


If there is no activity whatsoever when you press the power button on than you have likely blown the internal power supply fuse. This will need a technician to repair.

Dell Dimension 5100 Won't start up


Hi

First disconnecting the power cord and re-seat all connections (Keyboard, Mouse espercially). Connect up the power cord and try powering the PC.

To help you troubleshoot a problem, Dell Dimension 5100 has four diagnostic lights labeled "1," "2," "3," and "4" on the front panel. When the computer starts normally, the lights flash. After the computer starts, all four lights display solid green. If the computer malfunctions, the color and sequence of the lights identify the problem.

If the computer failed to start up check the diagnostic lights color and sequence and Check the link below for more info (Assuming you have another system that can access internet)
http://support.dell.com/support/edocs/systems/dim5100/en/sm/tshoot1.htm#wp1120147

Alternatively, contact Dell Support with the diagnostic lights color and sequence to raise a service call if the system if under warranty.

Upgrade


according to this cnet.com (http://reviews.cnet.com/desktops/dell-dimension-5100-pentium/4505-3118_7-31429803.html) the dual core is not an option. I'm not sure if that means that Dell doesn't offer an upgrade, or if it's not possible. First, open your tower and look over the Motherboard for the manufacturer and model. Once you have those, google them and look for the specs of what cpu's are supported by that motherboard. If you can and do decide to upgrade, check with the CPU manufacturer to see how strong of a power supply you need for the more powerful CPU. You're might be ok, but you might need to upgrade the PSU (Power supply) with the processor. From your description, I can't tell what motherboard is in your Dell. That will be the limiting factor. Get the motherboard specs and you'll know what you can do.
