Recently one of my PC's has been having a bit of trouble.
It sometimes freezes and you hear the "capacitor noise" before it eventually comes back.
This happens when PCLinuxOS is up and running, during GRUB boot up, and when the BIOS screen appeared.
I have tried removing the dedicated GFX card in favor of the integrated one to reduce power consumption , but it still happens.
My guess is there is a problem with the power supply or capacitors, but this machine is only about 3 years old.
Does anyone have an idea of what the problem may be?
Of note: When the desktop is up it usually only freezes when CPU usage is high.
