My PC :
Desktop Acer Aspire T3-715, Windows 10 Home 64b. 21H1
Intel Core i5 Processor 6400
NVidia GeForce GTX745 4GB
Hard Drive : SATA3 1TB & SSD 128GB
Memory : DDR4 8GB
DVD-Super Multi drive
Card Reader
Integrated LAN 10/100/1000
Monitor : SamSung SyncMaster 933sw
Couple of weeks ago, the PC got stuck at the beginning of booting, when acer logo appeared on the screen.
It was like this :
1.Start button could turn power on,
2.Light in front panel was on,
3.CPU & graphic card fans spun,
4.Monitor was on & showed "acer" logo & booting stopped at this point,
5.Start button could turn the power off.
Except for these functions listed above, EVERYTHING ELSE WAS DEAD.
A repair shop tried to fix the PC but failed.
Today, I had the CPU cleaned & applied new cooler.
The PC behaves differently from how it was before the CPU cleaning.
1. Power on, continuing beeps B - B - B - in half second intervals.
1a. Before cleaning the CPU, there was no beep, no beep even when the PC was started.
2. And now the monitor is not on.
2a. Before cleaning CPU, monitor was always on after power on.
3. And the power on-off button becomes a one way traffic, only power on, not power off.
3a. The power button was normal before cleaning the CPU.
What do the beeps indicate & how to correct it, please?
Thank you.
