Siren sound and problem with launching...
First of all, while booting my computer makes sometimes this strange siren sound.
But bigger problem is that whenever I try to turn it on it doesn't boot properly.Simply it works but freezes. Pressing 'reset" several time helps and it starts working properly without any problems.
moreover, if I decide to shut it while working there are no problems with shutting and starting my PC.
All problems occur when my computer is not used for a long while.
my motherboard is EP-8RDA+
What can be the problem?
