my pc Is been acting up lately and I thought nothing of it but for some reason when I was playing borderlands my game kept freezing it had never done that so i thought that there was to many programs open so it stopped all the programs apart from steam and discord then i went back in and my friend left the game i made a new lobby cause he couldn't join when the loading screen came up the computer crashed so i texted my friend telling him the my game pc crash then i turned the pc back on Nothing was up on the monitor so i unplugged the hard drive then turned the pc back on still nothing doesn't even say that there is no hard drive so i turned it off and plugged in the hard drive still nothing so i took out 1 off my 4gb ram sticks i turned on the pc then i heard a loud zap where the over ram stick was (lets hope it didn't get fried) so i swaped the ram sticks then another loud zap and there was a battery acid smell sorta then i put the ram sticks back in then i turned on the pc then just the computer booted then it resarted then booted etc.etc so please help
