    keyboard is P2P and mouse is USB. Could I have possibly missed a connection as there are numerous extra plugins on the power supply? I thought I had them all marke but I may have missed one.

There wouldn't be anything from the PSU giving power to your keyboard and mouse. The mobo handles that unless your giving your mobo the wrong amount it needs which might be why your P2P and USB arn't working. Although it is odd that your mouse isn't working with P2P as that requires less power.

When I turn on my computer it beeps 6 times and there is no display on monitor.


Hello, depends on the make of your bios. Try here: http://www.computerhope.com/beep.htm if you try unplugging/reconnecting keyboard and mouse, never do it with computer powered on, unless they're USB connections, as you can blow the circuit. Regards, nicam49

My computers USB ports are not giving power to devises like monitor, mouse, and key board. How do I fix this?


restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer

click start control panel administrive tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X

you will need to update/reinstall drivers

right click to reinstall drivers

if you can see your usb drive but its not working

ports(com&lpt)right click update driver if this fails to fix the problem

check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems for a computer and its parts

hope this helps you

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer 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 they could be 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 electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error
try blowing out all of the dust from your keyboard using a fine air blower from an air compressor making VERY sure there is no MOISTURE in the lines.
dust causes static which causes lots of problems with a computer and its parts
click start control panel keyboard hardware then properties you should see driver details,you will have options to update driver,roll back driver,uninstall
make sure you have the driver for the keyboard before uninstalling the driver
make sure the lead is good and has a secure connection diconnect the keyboard then reconnect it then reinstall the driver(if applicable)
make sure the usb device is inserted correctly into the usb port (if applicable)
hope this helps
as for the mouse
make sure the lead has a secure seating if applicable or the usb device
make sure the battery is good (has full charge)also you might test the usb device for the mouse is inserted correctly into the usb port (if applicable)
click start control panel mouse you should see 4 tabs buttons,pointers,pointer options also hardware under hardware you can troubleshoot or
select properties under driver you will have the options to update driver,rollback driver or uninstall and under hardware you can troubleshoot the device
hope this helps

Whom ever told you too: "Unplug the cpu while holding down the power button".

Is telling you something that can "seriously damage" your cpu and computer.

Or did you mean "PSU" if so there is a particular format to do a Power supply check.
For the proper way use this link: http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph06788&lc=en&cc=us&product=405227&dlc=en&lang=en#N207

Also many other things can cause the problems your having. Could be your motherboard too.

If this does not work, post again be sure to include HP Pavillion Model number and Operating System (i.e. XP, 7 or Vista) that way we can help pin point your system needs. Also have you done any internal repairs lately? Recheck all your connections too.

If you find this helpful please vote.

When is the Hipro HP-A2007AE power supply cooling fan to be on?


The fan should run constantly. It needs to be replaced. Otherwise the power supply will shut down when it gets hot. It can usually be replaced, but if the supply is cheap, just go out and get a new one.

My monitor turns itself on and off with no prompting


Go into the control panel and check the system settings. You might have it set to turn the monitor off after a low number of seconds of use. If you have it set for 30 seconds, if you don't use the keyboard or mouse for 30 seconds, the monitor will shut off. When you start to use it again, it will come back on.

System is not workin properly


You might try this. Shut down the computer, disconnect power cords, disconnect everything at the back of the computer, mouse, key board, etc. Open the case, ground yourself by touching an unpainted area of the case and remove the power connectors to ALL optic drives and floppy drive if you have one. (Of course do not disconnect the hdd.)
Reconnect mouse, keyboard, etc., and power cords to wall outlet.
See if it will post now. If it does I say you have a faulty power supply.
I was given a computer which was doa. It would not post, after I tried the above routine it posted then booted to windows.
I replaced the psu and now the computer works fine.
Hope this helps!
