Suddenly today, my laptop crashed. The charger connection flash from off and on and then the laptop shutoff. I restarted it and it worked for a bit. The charger connection did again and the crash happened again. I noticed the charger (which is a replacement I ordered online) was really hot so I let it rest for a while. When I plugged it again, instead of shutting off the screen just froze until I force shutdown the laptop. I then tried the old charger that has a loose connection and there was no immediate crash. 20 minutes later, the laptop froze again. This all has happened within about 2 hours suddenly. The computer is an Acer Aspire V17 Nitro and I am completely stumped by what is causing this. The event logs just state:

"The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID" and some other things I cannot understand.

 

Any ideas or help is greatly appreciated.

Just a guess but I'd say that the old and new chargers need replacement.

Does the power adapter reflect the proper specifications posted below?

 

AC Input Voltage: 100 ~ 240V
Input Frequency: 50 ~ 60Hz
DC Output Voltage: 19V
DC Output Current: 7.1A
Power: 135W

 

Both the output voltage and current are very important.  The voltage needs to be the 19VDC, the current must be at least the 7.1A, it can be rated higher, but it can't be rated below the 7.1A figure.  If you have a multi-meter you can check the voltage to see if it is producing the 19VDC. 

 

Is the battery getting a full charge?

We understand that the power adapter has a problem.  We need for the original poster to determine if this adapter is compatible with their computer since this is a replacement unit.  The other option is that the power adapter was defective from the factory.  If it's the wrong adapter... they purchase something they can't return or use.  If the unit is the correct adapter but is not working properly, time to send it back for either a replacement or a refund.  Time to wait for the op to respond to the questions. :thumbup2:

Sorry for the delay, time has been tight. 

Here are the specs on the adapter:

 
AC Input Voltage: 100 - 240V
Input Frequency: 50 - 60Hz
DC Output Voltage: 19V
DC Output Current: 4.74A (different and looks like this must be the problem)
Power: Doesn't say on the adapter sticker.
 
I think the battery is getting a full charge as the computer runs on it just fine (until it freezes.)
 
Here's the speccy log:
 
The issue stopped happening for a few days and today it looks like the adapter overheated again and the computer froze like last time. The symptom a bit before the freeze was the charge losing and regaining connection for a few moments. It does look like the adapter that was said to compatible with this computer is not.
 
I greatly appreciate your help, thank you!

The amperage should be 7.1A.  If it is as low as 4.7A this is not the correct power adapter for your computer.  This definitely can cause problems.

Thank you! I've been using the older original charger since. Unfortunately it has a poor connection and only works when its 3/4 plugged in. This time, the same crash happened. I felt the charger brick, it felt warm but not burning like the replacement charge. I then checked the charger pin/insert and it was hot. Now the original charger is completely dead. I assume this last crash was due to the old original charger finally burning out?

There is the possibility that the female socket in the laptop needs to be resoldered or replaced.  On some laptops this is a separate card and is comparatively easy to replace or repair.  I'm out of time  and will not be able to get back to you until tomorrow. 

 

Here is a video which shows how to replace the socket.
