My computer starts up, fans roll, but no video out put. Cleared CMOS, swapped video cards, took the battery out and put it back in, but nothing, no respond. I even took the RAM out no beeps even. I'm lost and have no idea. I think its my motherboard, but some forums people seem to think its the PSU. Appreciate any help.
To get beeps( hear) the board must have audio output. Not all have this device. I have some, mainly ASUS boards, that don't have. But anyway, in order to get proper help, u have to post your computer specs, in detail, and describe some unusual behavior before this.
Second, do you have a case (system) speaker installed?
If you case or motherboard didn't come with a system speaker you can buy one here: http://www.cwc-group.com/casp.html
or scavenge one from an old case.
