Screen goes black for a couple of seconds and comes back up
To give a bit of a background - I had to change the mothboard of my system last month because of an incident of burnt PSU
Coming to the current situation - since the last few weeks, I have noticed that when I am viewing a video on fullscreen mode, I would often hear a system alert sound, like the one you get when you plug and unplug in a pendrive. It doesn't occur always though.
I immediately check the events viewer to see if it has logged anything, but no errors/ warning show up there that could describe what happened at that time.
Moreover, the screen often turns black for a couple of seconds and comes back to normal. Sometimes before it comes back to normal, I could see my screen changing to a much lower resolution and then back to the original one.
Again, nothing related to graphics or monitor in the event viewer.
My system specs:-
AMD FX - 6100 CPU
Asus M5A78L-M-USB3
AMD Radeon HD 5450 GPU
Corsair Vengance - 4GB x 2
CM B500 PSU
Corsair MX-100 - 256 GB SSD
Seagate - 7200 RPM - 500 GB
Seagate - 7200 RPM - 160 GB
This didn't start happening following a clean install, btw.
I have searched for updates to my graphic drivers, but found no new updates.
The monitor is quite old though - 6-7 yrs I guess.
What could be happening here?
Many thanks
