(currently posting this in my laptop)

Everything is fixed, my brother just needed to reseat everything (E.G. Removing the GPU and placing it back in) and clean the Dust Collector (it's been sitting there for 4 years now). Also I removed the laptop case, and placed the "burnt" video-card inside and it runs very damn well. I played NFS Shift with the laptop, which has a 2.5 GHz processor (lag as fuck though). The games I tested with this magical "burnt" video-card are: Counter Strike Source(21 fps), Need for Speed Underground 2 Max Settings(15 fps), Minecraft (minecraft lags for some laptops, 16 fps), and finally, Call of Duty 4 Modern Warfare (23 fps)

    In all seriousness, do you mean the entire monitor doesn't turn on or you don't see anything on your desktop?

    The monitor is plugged on, EVERYTHING IS WHERE THEY ARE SUPPOSED TO BE, (monitor is a 17"TFT LCD monitor) and when I start the monitor, it says that its not plugged in. IT IS PLUGGED IN AND DONT EVEN START WITH THOSE RAM AND MOTHERBOARD BULLSHIT

    If you've ever had a second monitor, and now you switched back to a single monitor, that might be your problem. And calm down or I'll abandon thread.

    I would guess it's a problem relative to your graphic card. I personally encountered two cases.

    1. The monitor would turn on but there was nothing on screen. No signal. Reason= The Graphic card happened to overheat and broke.

    2. The monitor would turn on, something would appear on screen for 2-3sc and then turn black but the screen still detect the graphics. (Green led to prove it's activation). Reason = The screen's condensator was too old, it needed to be changed.

    In your case it seems a lot like a Graphic Card issue.

    That's not a problem with your monitor, I'd this problem a while ago, try to make this:

    Unplug the power cable and touch the side of your tower for removing your statics, remove the HD cables, remove RAMs and remove the clock battery and let it out.

    If you know where the BIOS chip is located and it's jumper, go to the jumper and jump the plug from 1-2 to 2-3 depending on the model of your mobo. Let the battery and the jumper in this custom position at least for 20 seconds. (The jumper I'm talking about is the cleaning CMOS)

    Re-plug all components, cables and don't foget to jump the plug of the jumper from 2-3 to 1-2.

    Try to start your computer.

    hope it helps ! google your mobo model for manual instructions and component map !

    Even with a burnt graphics card you should still be able to see the BIOS screen.
    Doing what NickMaps suggest is probably your best bet, if your motherboard is a few years old you might have to change those small clock-batteries if they are out of charge - I have never experienced or heard about anyone that have done that though, but that could be worth a try - just measure the voltage and see if that's the case.

    If you have a laptop, try plugging the DVI/VGI cable (or HDMI) into the laptop, if the laptop does not have a plug into one of those adapters (which i have no idea why it shouldn't), then find another way to test out if it's just your computer screen.

    Another option is testing out your Power Supply, my power supply fucked up when my external hard drive slammed on the back of my case and my screens stopped working, my mouse and keyboard were lit, so i knew it had power, it just wouldn't go to my screens.

    Last thing i can think of, is your video card, it is a 9000 series, which is kinda old, it might have crapped out on you, if you have an extra screen, test it out, if not then i would find some one with a computer, plug in your Power supply/Screen/Video card, not all the same time, just one by one to cross out which one works and doesn't.

    I'm going into computer repair with my A+ certification on it's way, and just from self knowledge, i can tell it's one of those, or it could be something stupid like your RAM, which RAM always is the #1 thing to go on a computer.

    If you hear your computer BEEP on start up, it's not your RAM/CPU/Drive, that means it has booted up fine.

    Hope all is well and you figure out what is the matter with your PC bro.

    The first part of your post is correct but the second half is not. Namely, RAM is not always the first thing to go on a computer. Hell, I'd say it's usually the last thing to go, if ever. Second to that, though, is the simple fact that POST codes depend on the BIOS so you cannot make any statements regarding what a single beep means. (I'm rather surprised you could get A+ certification without knowing this.)

    However, I must say, good job. Your method is definitely the best posted so far and I hope OP follows it.

    In fact, OP, I do not think you should read the other posts on this page. They contain too much false information.

    Now then, in the event that the display is broken, I want to mention that they can be fixed. I've only ever had to repair one but all it needed was a new capacitor, and that seems pretty common. Installing a new one is simple enough, and identifying a dead one is easy too, although I really can't recommend trying this if you don't have any experience. I have no reason to believe the display is the problem here, as you haven't exactly provided much information, but at least it's not a lost cause. I mean, a new capacitor could cost five cents and that's a lot cheaper than a new display.

    This post makes me come off as a smartass, doesn't it? Oh well.

    Happend to me once. Try changing that little battery inside of the pc. That's what I had to do. It's used to keep clocks and stuff running while the pc is turned off. Only try that if you get a beep noise and the screen stays black, though. If it's not that...buy a new graphics card.
