Those must be the jumpers they were the ones responsible for the connectors on your motherboard . If that had spark chances are the motherboard might be affected.
Advised contact the technical support if the warranty is still up but that might void the warranty if they asked why did you open it . If its out of warranty asked tech support for the part number and asked them to connect you to spare parts dept.

Dell dimension e510 flashing amber light USB front panel

If you are comfortable around computers, you could try the following to test the power supply. Unplug the cord from the power supply, hold the power button in for about 15/20 seconds, open the case, unplug the 24-pin power connector from the motherboard and jump the Green wire to one of the Black wires, reconnect the power cord and power the system on and if power supply fan and hard drive run, then the PSU should be good. Note: Do not remove any wires from the plug, use a small piece of wire or a paper clip as a jumper. Power supply checks out and the system still does not work, again remove the power cord, hold power button in for several seconds to discharge the residue power, reconnect the 24-pin connector to the motherboard. Remove all the PCI cards, the video card [if applicable], memory, all peripherals, disconnect the data and power cables to all the drives, check that the front panel cable is connected to motherboard, with nothing else connected to the system, reconnect the power cable and power the system on. If you do not get any beep codes or diagnostic lights on the front panel, then it would appear that motherboard has died.

System shuts off within seconds of turning on and fan starts

Motherboards are designed so that holding in the power button for 4-5 seconds shuts the system off. The On/Off key getting stuck or something shorting the pins on the motherboard that the On/Off switch is connected to can cause this behavior.

Open the case and remove the little two wire connector (usually one red and one black wire) that runs from the motherboard to the front panel switch. Then carefully touch both the pins on the motherboard at the same time with something made of metal such as a paperclip or small screwdriver, remove it as soon as the computer starts to power up. If it still shuts off, you probably have a motherboard malfunction. If it starts normally, the switch needs to be replaced/repaired.

ASUS P4S533-E. Question : The system intruded, chassis opened or tempered before. Please check the system. What does it mean?

Some computer-cases have a small switch that is "triggered" when somebody removes a side-panel. The trigger sets a flag on the motherboard, to say "intrusion", i.e., somebody opened the case, possibly removed something (RAM, video-card), or cut some wires.

You need to inspect the computer, to see if the "intruder" did anything to your computer.

Then, you can enter BIOS SETUP mode, and "clear" that flag.

Optionally, you can then "disable" that "chassis intrusion" programming.

How to change battery in my 2002 Dell 8200 desktop

Desktops only have a very small battery for maintaining the clock, it will not keep the machine turned on after power is removed.
If you open the side of the desktop (once you've turned it off and removed the power cord), you will see a small coin cell battery on the motherboard (main panel). Generally this is a watch battery like a CR2032, or something similar. You can gently pry this out of the holder and replace it with an identically numbered battery.

How do you replace the cooling fan of the Dell dimension 2400 desktop computer?

To replace the cooling fan follow these steps:-

You will notice that replacing the fan is not specifically mentioned, but it should be fairly easy.

Open the case as noted in the instructions, follow the power wire from the fan to the motherboard, then unplug the connector from the motherboard, and remove the assembly.

Some of the earlier fan shrouds just lift up and out, but others have tabs to hold them in.

Regarding the fan, there might be two release levers accessible from inside the case, but the one by the PSU can be hard to reach.

It might easier to push the retaining tabs, in from outside, using a small screwdriver, pen or whatever.

The installation of the new fan, is just a matter of fixing the new one in place and connecting the cable.

Good luck, and do rate the solution if got help

Continus beep is coming but some time system is working properly

I suspect that a lot of dust has accumulated in your system. open up the PC side and by using a blower get all the dust out. Remeber to blow in the Power supply also. Now remove the ram modules and clean their connectors with with the swipe of your fingers but be very careful about static charge, touch your fingers with something metallic earthed to the ground before doing it. also clean the ram slots on the motherboard with a small brush. also if you want you can clean the connectors of other devices like hard drives, cd-roms etc.
