Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electic extensions or just replace them they are probably faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error hope this helps
or it might be your graphics card make sure its securely seated and there is no dust built up
on and around the graphics card hope this helps

I just reset my dell computer back to factory setting. How do I now reset up for internet connection. My provider is verizon and I am using internet explorer


You want to reset your internet connection???
If yes then follow the given steps....

Step 1

Turn the modem so that the back of it is facing you. Locate the power supply cord connected to the back of the device.
Step 2

Gently unplug the power supply cord and leave it unplugged for about 10 seconds. If you also have a router connected to the modem, disconnect the power cord of the router as well.
Step 3

After about 10 seconds reconnect the DSL modem power cord. Wait for the status lights on the front of the unit to come on. They may blink at first before turning solid green, or they may first illuminate as orange, then turn green, depending on the modem model. The "Internet" and "Incoming" lights may continue to flicker, this is normal operation for modems.
Step 4

After the modem is reset, reconnect the router power supply if you have a router. Wait a few minutes before resuming normal Internet use.

Power-on LED illuminates when power button is pressed, fans spin, and boot tone chimes, but there is no video


1. Reseat video card. (Make sure video card is fully inserted in connector and end of card is secured by the connector latch.)

2. Reset PRAM (restart computer while holding down Command-Option-P-R keys until second boot tone chimes)

3. Replace video card

4. Reset logic board. Refer to "Resetting the PMU on the Logic Board" in this chapter.

5. Replace logic board

Resetting the PMU on the Logic Board

The PMU (Power Management Unit) is a microcontroller chip that controls all power functions for this computer. The PMU is a computer within a computer. Its function is to:

tell the computer to turn on, turn off, sleep, wake, idle, etc.

manage system resets from various commands.

maintain parameter RAM (PRAM).

manage the real-time clock.


Important: Be very careful when handling the logic board. The PMU is very sensitive and touching the circuitry on the logic board can cause the PMU to crash. If the PMU crashes and is not reset, the battery life goes from about five years to about two days.


1. Disconnect the power cord and check the battery in the battery holder. The battery should read 3.3 to 3.7 volts. If the battery is bad, replace it, wait ten seconds, and then proceed to step 2. If the battery is good, go directly to step 2.


2. Press the PMU reset button once and then proceed to step 3. Do not press the PMU reset button a second time because it could crash the PMU chip.


3. Wait ten seconds before connecting the power cord and powering on the computer. If the computer does not power on, there is something else wrong with it; refer to the "Startup Failures" section of "Symptom Charts" in this chapter.

Note: The above procedure resets the computer's PRAM. After resetting the PMU, be sure to reset the time, date, and other system parameter settings.

Try resetting the router . Press the reset button for 10 seconds and after 10 seconds unplug the power cable but continue pressing the reset button for another 30 seconds after 30 seconds plug in back the power cable and continue pressing the reset button for 10 seconds and release it after 10 seconds.

try to open an Internet browser and type in 192.168.0.1 on the address bar. It should give you the DLink page. Once you have that configure your connection.
