Whats wrong with my computer?

All my wires are in right, it's not overheated, and it's still fairly new(two years)
When I turn on my computer, my monitor goes on, then off instantly(yellow light) and it's not my monitor, the computer turns on, but does nothing.
What could be wrong with my computer, what can I do to fix it, and how much will it cost if I can't fit it?

The best way to debug problems like this is to eliminate one step at the time.
You say it isn't your monitor, but have you tried another monitor?
Have you tried another graphics card?
My guesstimate would be one of these two tings.

Overheating, I wouldn't think so either no. That usually manifests itself in other manners.

It could however also be hardware problems with many of the other components, so as far as you have a chance, try other components to replace them with - if you have another harddrive for example, or can borrow one, try that out and see it is springs to live.

It is the best way to debug such problem - remove one factor at the time - lest you want to bring it to professional help which can cost some money depending on the issue.

Yes, I have tried another monitor, but I know the graphic card and monitor aren't the problem, It shuts off way to quickly and doesn't make any prossesing sounds.(I have the loudest computer ever)

Have you checked your PSU? I suspect that it could've probably broke down. Happened to me before when I couldn't switch on my previous computer.

Then possible the CPU is fried.
Loose connection on the cables somewhere.
PSU possible as well as suggested by Des
And so on with motherboard down the line.

Only method as said - outside a company - is to isolate each hardware factor and eliminate that from the equation.

Your post is a tad on the vague side... it often helps to know the specifications of the system... but when diagnosing problems keep your ears open. Most problems on booting lead to a series of beeps from the internal speaker and go a long way to finding out what the problem is (of course it helps to know the manufacturer of your BIOS [Pheonix, Award, etc.]- to know what the beeps mean). There are any number of things that will cause your computer to fail like that... the most common are the RAM, CPU, Graphics Card, or Dead HD (though normally that doesn't effect display)... but they all have these characteristic beeps if they fail. If you don't hear anything when you boot... then the chances are your motherboard is dead.

Only other suggestion that might help (has worked for me on one occasion with a similar boot failure) is to either use a vacuum cleaner or air canister and clean the PSU (but don't take the case off the PSU), and to clean the CPU heatsink (but again do not remove it - unless you know what you are doing!) I have a coolermaster case that acts like a vacuum cleaner and I usually clean out the dust every 2-3 months to keep the airflow and performance good. Have had a crash before just because of dust buildup... and 2 years can mean a lot of dust.

Ok, nothing was wrong with it.

Somethings wrong with I wire connecting the computer to the monitor. I'm an idiot. Thank you to everyone for your advice.
