My monitor wont work when i start up my comp, after i finished cleaning my computer from dust n stuff it works when i hook it up directly to my motherboard or whatever it is but it doesnt send a signal when i hook it up to my graphics card i think i f***ed it up or something while i was cleaning my computeris it f***ed? Can i fix this prob? Can i just keep using my computer with it plugged into my motherboard?

do u have acces to another system?If yes try it to another system(desktop or laptop). Does your board has onboard video? if yes try to connect direct to motherboard.
edit: make sure graphic card is installed correctly.

May be the graphic card is bad,try to instal your graphic card into another system and post your full system specs.

". . .and im not sure if my motherboard has its on video" But that's what you were using when the monitor wasn't connected to the card, right?

"ok now my monitor doesnt work at all after i walked into my room and closed the door it shut off right there as i walked to it"

Sounds like it may be overly sensitive to static. I had one like that. I would ground myself against the table it was sitting on and the computer would reboot. I built another PC the same way and it never had that problem.

Is it plugged into a grounded outlet?

As already mentioned you should try the video card in another computer or else try another card--even a cheapo--in the non-working PC.

Bah, humbug

using a diff computer and i dont want to kill this one is there any other way to test the graphics card? And what do you mean ground yourself????

You know, static. You walk across a carpet on a dry day and touch something metal and get a shock. Touching the metal discharges the static buildup in you. The metal is a ground or partial ground. An ideal ground would be something like a metal faucet handle. Touching the metal is referred to as 'grounding' yourself. That way when you touch electronics the static doesn't ground though the circuitry and possibly ruin things.

A grounded outlet is one with three prongs, the bottom rounder one being the ground. Sometimes idiots cut off the ground prong to use in an ungrounded outlet or with an extension cord that has no ground prong.

A bad ground may have nothing to do with the power cord. It could be a internal fault in the device.

I'm not saying your problem is a bad ground--just that it could be.

I know of no practical way to test a graphics card except to plug it into a working computer.

Oh, should have asked earlier, does your graphics card need a power connection from the PSU? If so, is it connected?

Bah, humbug

Did you use a vacuum cleaner on the tower?

A grounded outlet is not for grounding a person's static buildup, although I think those grounding wrist straps connect that way. They're designed to provide a path to ground if there's an electrical fault that causes current to not go where it's supposed to.

Yeah, after all that I bet he used a vacuum. They're a good source of static buildup too.

Possible the OP just loosened something. Re-seat all cards, cables and RAM.

I use a vacume in mine all the time, have for years. It is one of those little ones ment for a car. Actually all that goes in the computer is a small hose or rubber tubing and a straw. It's not a high powered suction either. Someone convinced me, back when I first started messing around inside that dust particles can reside on components and become charged - or + depending on the compeonent. When blown around they can land on oppositely charged component and cause a short. I know now that is fairly lame but I have a system that works so I don't mess with it.


Likely

I want to go like my grandfather did. Peacefully in his sleep. Not screaming at the top of my lungs like the passengers in his car.

Sounds as though likely has a portable vacuum that he has used without incident.

That does not negate the fact that a static charge does build up in a vacuum cleaner hose from the rapid passing of air. That charge can discharge into the computer.

i did not use a vacuum at all and yes my computer is grounded, i just blew away (using my breath) the dust now that i think about it was that a bad idea? and i should reseat my cards and stuff? you mean take them all out and put them back again? and im not sure what a PSU is.

PSU = Power Supply Unit. You can remove the cards and stick them back in or just firmly push down on them to be sure they are in all the way. Cables and memory too.

ok i removed all the stuff and put them back in and now i can use my monitor again but it doesnt work unless i put it into the motherboard slot thing. i removed my videocard and everything works fine but then i cant play games.......... thats why i was cleaning my computer in the first place i dont know why but i cant get my video card to work, the fan on it runs and everything does that mean it works????? maybe i put it back wrong or something. idk and i dont want to risk the only other computer i have to test it.

I just reread your first post and realized you have both on board video and an add in card.

So when you connect the monitor to the removable card it doesn't work?

Then your add in card is probably broken.

Remove it and leave it out. Then use the one attached to the motherboard.

The only way to know for sure whether the problem is the graphics card would be to try the card in another machine ( as long as it is compatible) or try another compatible graphics card in your machine. That will tell you if the card or your motherboard AGP/PCIe slot is the problem.

What may be wrong now is that your on board graphics chip is not setup correctly. You may need to install some graphics drivers for it.

Or games that you already setup are looking for the card you were using in that game. If that is the case you should be able to set the game hardware up to use the curent graphics.

You do have graphics or you wouldn't be able to read the screen.

One other possibility is that the on board graphics may need to be disabled in the BISO screens.

You never explained what the original problem was.

Was the add in card working and all of a sudden stopped working?

I would think that the onboard graphics chip simply does not meet the minimum spec required to run modern games. OP needs to get a graphics card in and working in order to play.

That could also be the case. Kind of hard to know for sure.
