PC turned on but won't display anything

[SonicSkywalker]

I've reseted the cmos battery, cleaned and make sure the RAM is inserted correctly, the monitor got signal, but when I turn on my PC it's just blank.
Any help?

New, or old setup? What specs?

Nevermind I got it fixed .
I swapped the RAM slot
