i just clean my pc a while ago 'coz it's fan is going loud so i thought to clean the fan and so the mobo and ram and then when i turned it back the monitor doesn't display any, the keyboard and mouse has no lights making and no beeping before it turned on though the CPU is running....



i triple check the plugs and cards but no luck... i just use a cloth to wipe dust...

what would be the problem to this?
anyone help!!!!!!!!
