My PC's Ez cpu debug light on mb is staying on and monitor not getting any signal.

Sorry but you have post on a tech forum asking for help but have provided zero information about your computer or it`s hardware, this makes it impossible for anyone to even hazard a guess as to what is going on.

Is the computer a custom build or brand name such as Dell or HP, if a brand name provide the model name or series number (not serial) if a custom build post the brand and model name or number for the following:

OS
CPU
Motherboard
RAM (including the amount and Number of Sticks)
Add on Video Card if one is used
Power Supply Unit

Providing these details will enable folk to better help you.


If the system will stay on long enough lets see what the speccy report shows.

So other can assist let get a speccy report.

Do not forget to post the make and model of the PSU if this is a desktop.

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

To publish a Speccy profile to the Web:

In Speccy, click File, and then click Publish Snapshot.

In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

Does the system seem more stable if booted in Safe Mode?


When was the last time the dust was cleared from the system?

Get some cans of compressed air and blow the system clean. Make sure the system is powered off and unplugged. Remove the battery if a laptop if the battery can be removed.

Read the instruction on the can. Spray in short burst and when the can start to feel cool to the touch switch to a different can. After they warm up to room temp they work fine.

Do this in a well-ventilated room or outside this way the dust does not settle all over the inside furniture or worse you or someone inhaling it.

Do NOT turn the cans upside down, turn the system. Remove the battery and blow that our as well.

NOTE: You take the chance of wrecking the bearings of fans with the compressed air. Compressed air can actually accelerate the fans beyond their rated speeds and damage them, if you are cleaning them out with air, it is often recommended to hold the blades in place with a toothpick or other non-conducive material.

NOTE: Do not use a vacuum to clear the dust they can cause a static discharge and end up toasting the system or a components. There are also jumper on the boards that could be sucked off and then the system would be bricked.

Clean the keyboard
Put the with the laptop facing down then gently rub your hand back and forth over the keys this will knock some of the larger pieces out. Then place the system on its side and blow the keys (remember to use short burst like before) starting from the top working you way down. Heat form portable computers is released through the keyboard.
