Computer turns on but won't boot
Hi! I'm new here, just registered in hopes I could find some help, thanks in advance : )
My computer worked just fine last night. Tried to turn it on this morning, and it turns on fine but it won't boot up, no power or anything going to the monitor. Also, the disk drive is making loud short whirring noises at a rhythmic rate, and the green light on it flashes on and off with the sound. Put in a new disk drive, same problem. Monitor works fine on laptop.
Leaning towards mobo but really hoping it's not. Computer is over 5 years old, can't imagine it would be very easy to find a decent replacement that could support all of my old components since everything is sata now :(
Anyone every had this problem? Some insight would be wonderful : )
