Question about Computers & Internet
Ok when i turn pc and tower on it only says no signal monitor works thats it nothing eles am i missing what plugs into p3 and p4 i know nothing
Sometimes if a VGA cable is not screwed into to both your Tower and your Monitor, it can get loose and thus resulting in no signal.
Another cause of a Monitor Displaying the no signal message would be due to the Graphic Card failing, or possibly due to the Graphic Card not correctly being seated.
Usually P3 and P4 refers to a cable on your power supply that needs to be attach to your motherboard to supply extra power.
If your P4 cable is not plugged in before turning on your computer, this will also result in your Monitor displaying the no signal message.
Keep in mind though, if your computer has not been opened or is not a custom built PC, you should not have to worry about such issues as your P4 cable should in theory be connected. However I guess safely checking won't hurt anyone.

SOURCE: No video signal
The video card may have a jumper next to it or it need to be reset in bios If you know how at start up prees F1 or F2 or Del one of these will open Bios in the bios menu you will see setup instructions on the side or the bottom follow them and save if you are trying to add a video card it should say onboard or pci slect pci then press esc on your keyboard then press F10 to save settings then restart pc this should work but check the hp website for downloads get the manuel and find out about the video jumpers.

Do you have two video outputs on your PC ie. one on the motherboard adn a separately installed card maybe? If you do you need to set the BIOS so that it uses the AGP/PCIE video card and not the 'onboard'. Try the onbopard vodeo card first to see if you get a signal there.
If you do NOT have two video outputs, and you can not see a signal then you may have a prblem wiht your monitor itself. Is this a known working monitor to start with?

Do you see the BIOS splash screen or anything?
Try booting into safe mode by pressing F* as soon as you power on the computer. If the monitor works, then it is a bad driver. Roll back to a previous restore point, boot to last known good coonfiguration. Last Known good configuration is available from the same as the safe mode screen.
If this is helpful, please comment and rate. Have any other questions, please let me know.

Monitors are programmed to go to sleep when there is no input. If you shut it down on the other "tower" also it will do the same. You need to physically hit the power button on the monitor to actually shut it off.
