I remember the times when my pc was beeping upon booting, I just re-seat the RAM and the problem is solved. Now my monitor, keyboard and mouse has no signal even after I changed my CMOS battery. I first got "CMOS settings wrong" as my initial error. My CPU just lights up with fans running, but the monitor and peripherals aren't getting any signal, like the keyboard and mouse don't light up. So would you say that re-seating the hardware would solve my problem? If yes, then which part or parts should I re-seat so that I can look it up on how to re-seat it on Youtube. Thanks.
