PC won't start ( 3 beeps into 1 long beep)

[Xcyted]

Hello everyone. I purchased my gaming PC like 2 years and it was fine till a few weeks. One day I started the PC normally but it took me straight to the BIOS settings (without pressing anything at the start). I quit and went ahead for a normal boot. I noticed that my network adapters were not recognized, thus the internet not working. So I restarted the computer but it won't load up, instead I got 3 short beeps into 1 long and that's it, so I took it to a technician and he got it fixed (I asked him what the problem was, but like most, he won't clearly tell me what it was). Today I got the same exact problem, what I did was I took out the motherboard battery and put it back again. Started the computer, took me to BIOS and chose to load up settings and start normally. The PC started working normally again. Can anyone please tell me what the problem can be and how it can be fixed ? Thank a lot !

P.S. I may not be familiar with some technical names, so please make it as clear as possible.
