    The power light will go on, but the fan will not. I need to try powering up 5 or 6 times before the fan starts and the program loads. The model number of the computer is A810n
    Thanks for your help!

Sounds like a power supply issue.. Check the mother board for a light when the power is on (some mobos will not have this light). If there is a light, but it does not go on when the power is connected, replace your power supply.

Also, please post the model number of your computer.

    Have you recently changed any hardware? Added new ram or a different graphics card??

    I still have to go with a power supply issue, and would suggest replacing it. If that doesn't improve it, just return to store...

It can a problem with your graphics card or your Ram, Try removing your graphics card and reboot the machine. If it works then it's the problem with the Graphics Card. If it is not working then and still sticking with the old 3 beeps then Remove your Rams and Insert them individually or replace with a spare one or a new and see if it works.
Usually this will solve your problem. Please let me know if you can't solve even after doing this solutions

Power supply on HP MediaCenter m7664x

Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the onboard)

Switch on and check the fans on the PSU and CPU are running. If not you may want to try a replacement before you go any further.

If you hear any beeps these can indictate where the fault is.
either of these sites below will help you further with that

Beep codes Pc

More beep codes

Power up the pc and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.

Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it

My printer keeps giving a paper jam error no paper is jammmed

Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.

This will reset the purge count value. Then the printer will restart,
try this step by step.without missing any thing. thanks

I need to know how to reboot my packard bell pc

Under the start menu there should be an option to shut down; restart; sleep. Use the restart option & it will start rebooting. If this does not work then close all your programs and hit ctrl+alt+del twice. This should start a reboot. Hope this helps.

HP Pavillion automatically restarts after shutdown

indication of a failing power supply??? I dont think so.
more like a driver is corrupt or better yet have the on board nic card set to turn on, is there a plug that has wire attached to the nic card, unplug those and see what happens.
