No monitor or keyboard, fan is loud, Monitor puts up th no input message but wont turn on, keyboard lights are not on either

> fan is loud

When you first turn the computer on, the full runs at 100%, until the motherboard's "POST" (Power On Self Test) procedure has checked all the hardware, and "beeped" the speaker just once.

So, no "beep" (or multiple "beeps") and the 100% speed of the fan suggest a hardware problem with your motherboard.

Take your computer to a qualified technician for professional trouble-shooting.

Has anything changed since it was working last? check that first
Next -- the Beep codes indicate a hardware problem --the PC was unable to POST(Power On Self Test-)-but DELL's beep codes closest to what you described is either 1-2-video card not detected or 1-3-1-1 which is Memory (RAM) error adn the PHEONIX beep code of 1-3-2 is Memory error also-- so be sure all cards and chips are seated properly--I dont think its the hardrive --a PC can still boot and POST without a hardrive.

My hp computer wont display picture and makes a beep noise when i turn it on

It should make one beep. That means it passed the self-test.
If there is nothing on the monitor (is the monitor light green or yellow?)
then the monitor is bad.
I suggest you try another monitor to be sure. Borrow one from a friend.

Hp pavilion a705w Light flashed in front and back on and off

Try a different monitor with your PC. If it does the same thing then you know the problem is with your PC. Also connect your PC to a different monitor. If it works OK then your monitor is bad. Does it beep at startup? Describe beep codes and someone on this website will decipher them for you. This might help to diagnose the problem.

The power supply unit is bad. You will have to replace it. Also, it is custom specific ~ write down the specs of the PSU and order it from This recently happened to me.

Your Monitor is not connected properly

Connecting Your Monitor
1. Turn off your computer and unplug the power cord.
2. Connect the white connector end of the DVI cable attached on the monitor to the connectors on the computer.
3. Connect the USB cable that was included with your monitor to the computer and the upstream USB connector on the monitor. Once this cable is connected to the computer and the monitor, you can use the USB downstream on the monitor.
4. Connect any USB devices.
5. Connect the power cord.
6. Turn on your monitor and computer. If you do not see an image, see Troubleshooting Your Monitor.

NOTE: The Monitor will display full screen in White, Black, Red, Green and Blue color rolling pattern on screen if the DVI cable is not connected. This self test pattern will be displayed continually when Monitor detects that DVI cable from Monitor to PC is not connected.

* Check connection integrity at both ends of the video cable.
* Ensure the monitor and computer are plugged in to a working electrical outlet.
* Ensure power button is depressed fully.
