My computer started to crash since I changed ram type ddr3 to ddr2 and bios reset. I had to do that since my motherbaord ddr3 ram slots are not working anymore. Since then my computer freezes. Sometimes there are BSOD suddenly coming up or when I shutdown computer. And they say different reason why they happned. Sometimes when I open a software like Firefox, the crash report windows opens stating firefox crashed. And when I start playing a game the same thing happens. I would have tried to solve the problems by myself but there are so my different erros not sure where to start.
Please help, thanks.
