CPU powers on but monitor shuts off

I have an ancient HP Pavilion 7940 desktop pc that powers up but the monitor clicks on but then goes to sleep. I tried swapping out monitors and it does the same thing meanwhile the CPU is still powered on. What can I do to fix it or what do I need to do in order to save the info on the computer?

If you are using a video card try to remove this and clean the contact points(bronze color) because the contact of this to the slot of the mother board is too slim and this causes no signal for the monitor. while if you are using an on-board video card there is already a problem with the slot or thry to inspect the cord and pins if no deformities. if you think there is no problem with these then you need to buy a video card prior from this you must try to see the specs according to the motherboard manual because we have different types of videocards

My HP monitor keeps going to sleep,it reads (power button lockout) How do I fix this?


This is because the monitor's Power Button Lockout function is enabled. Press and hold the Power button for 10 seconds to unlock the Power button function. Your sleep problem should also be related to the lockout issue.

Your computer has served you bravely and is now wounded in battle.

arfoob43 either your power supply has died or you computer mainboard is toast.

See my published guide dealing with this matter it is entitled My Computer is not turning on!!! Is it dead!!! No POST!!!

To actually fix it requires a bit of electronics skill. First you will have to diagnose the component that has failed and then solder in the replacement component.

Take care

Power supplies tend to be either working or not working. I would start with the computers memory, reseating the memory cards (there are plenty of tutorials on the web for how to do this). If the power supply fan was running, chances are you did not need to buy a new one. Does it do the same thing with the new power supply?

Try running a penny across the monitor's cable pins while powered on. If you contact a certain pin with the penny and the monitor exits sleep mode, your monitor is fine. If not, buy another one.

Cpu says no input vga signal, then goes to sleep


The no input VGA signal just means that the monitor is not receiving anything from the graphic card on the tower. Is the card a digital (DVI) output card? You'll know by the connector, it's white and slightly wider than a standard VGA connector. If so, perhaps the monitor is set to the wrong input?

If that isn't the case, and the computer is using an on-board or built-in graphics controller, you could try resetting the system's CMOS settings by setting the clear-settings jumper on the system board, or simply remove the plug and CMOS battery for a few minutes. Check the computer's documentation on the exact steps to do this.

Hope this helps!

PC shuts down while running Windows


Attempt to boot the machine in Safe-Mode.

While powering up continuously hit F8.

You will get a Boot Option Menu, Select Safe-Mode boot

If you can get into safe-mode I would suggest to try doing an online scan, as it sounds like your issue could be related to malware:

The computer shuts down with no warning.


I don't believe that this would be a hardware problem. Most likely the power settings for your PC are incorrectly configured for your liking. To repair these settings click Start/Control Panel, then click Power Options. From that panel, you will be able to set your power schemes. I would recommend the Always On option.
