turned off computer during factory reset, now it turns on but display says no signal

[andrew.pickeringnz]

I recently bought a second-hand computer, and it ran good but still had some files on it, so I factory reset it. during the reset, i was getting nothing on the display for about 45 mins to an hour, so i turned it off, turned it back on, and it turned on fine, but still had the files on it, so i tried resetting it again. same issue happened so i turned it off again. now when i turn it on, the computer turns on, beeps twice and pauses, then beeps twice again, and the display says "no signal" its not the monitor or the cables as i have checked those, and they were working before the reset anyway. i have no idea what to do, help?

You need to know the manufacturer of the MB so you can use the beep codes to diagnose it correctly.
Might be a RAM issue, so remove all sticks and try and boot it up.
I had this happen the other day after a hard reset during a lockup, except it beeped about 20 times instead of 2.
