What have you done so far to figure out what's wrong?

Did you check to make sure the monitor is on and has the cables connected properly?

I think you need to clean the RAM connectors, take them out of socket and wipe them (very very gently) with a dry clean cloth and put them back in the slot, now do a little blowing on the board surface, power the machine, it will work, if it doesn't... nah, it will work.

Are you serious? Or are you trolling?\

Are you serious? I have better things to do then trolling....

I have faced the same problem like 4 years ago, my pc will start - run in background... boot and everything, but no display, it's a head/tail situation, sometimes pc runs just fine and on next start OS will tell you that previous time you shut down without proper turn off. You press ctrl+alt+shift and same dark screen comes. I called my display guy, couldn't find the problem, three days later i cleaned my pc, and put the RAM back in it's socket, BAM! The pc works again.

Few days back it occurred again, one of the two RAM was gone, had it removed, pc works again. What can i say?

check the cable is connected properly and the monitor is set to the rite input...
check the monitors inbuilt menu.
mine for instance gives no signal if hdmi or analog is selected but digital or auto will give a picture.
auto will go through all available inputs till it gets 1 that works. while digital works if the dvi is connected.
analog for vga
and hdmi for the hdmi lead.
so yeah check your monitors menu input options.

OK, I asked because wiping the contacts on your RAM is a really good way if introducing electrostatic shock to the RAM and damaging it. I really would not recommend doing that as the first step. You can try to make sure the RAM is seated properly, but DONT wipe the contacts down, especially with a dry cloth. That's not a good idea.

Two, things, firstly, i don't know how and why would cleaning RAM's connectors with a dry cloth will cause 'electrostatic shock' i mean i am sure nobody is going to rub it until there is some static and a minute or two after PC is shut down, there is no charge in RAM, that's stupid to assume. Secondly, i believe most people who come to this forum know a little about hardware and cleaning and maintenance of pc is no rocket science, i clean my pc every month, using blower and dry cloth, in moderation nothing will damage your components, rest assured.

This is absolutely wrong. Every time you touch computer components when you are not "grounded", you induce microscopic ESD damage into your equipment. EVERY TIME! This occurs because your body can build up a vastly larger capacitance than the small traces on your motherboard, processor, graphics card, or whatever else you are messing with can handle. Often, this charge finds its way to a lower potential plain through the tiny traces in your equipment. Looking under a microscope it looks like a bomb was dropped on it.

If you ever get a chance to visit (or work in) a professional hardware environment, you will see just how seriously this is taken. Every unprotected touch of the equipment adds to the damage. This is why so many people come on the forums are complaining their stuff doesn't work and no solution can be found. That's why all of you RMA stuff so often.

You're wrong in thinking no damage will occur in moderation. It happens every time you handle your stuff. Damage builts up slowly until your expensive stuff turns into junk. Rubbing with a dry cloth is a really stupid idea as it exemplifies the voltage difference in your materials and will accelerate the damage to your equipment.

Maybe you haven't seen it yet, but if you keep treating your equipment like you have been, it will fail a whole lot sooner than if you treat it properly.

Don't believe me? Go Google some pictures.

Right, i owned a pc assembling shop/ cyber cafe, we ran 12 PC's... until two year ago, when i closed it, all were run, assembled and maintained by me, none EVER got junked or shot circuited. I have certification in hardware and networking endorsed by reputed organizations. Still, i agree i am not the very best at my job (started it, lost interest midway), but i know bloody well, that after you switch off your PC, all charge is GONE... absolutely.

Again, i expect people to know a little about handling and maintenance of their hardware, if you don't i cannot do much about that. I am not saying 'to bloody well rip out the pins of the component while you grind it with sand paper' just do a little feather touch here and there and you are good to go, i usually use brush exactly made for this purpose or my air blower that blows most dust particle.

Caution: Never EVER touch or try to touch the component while it's charged, ie at least one minute after power off.

Um, have you checked your video card?
March 3, 2013 11:18:41 PM

Usually no signal at boot means a bad video card, or an unseated one
