Computer Fails To Boot

[Sam =)]

Please take the time and read below computer experts:

Well this started when I was playing cs 1.6 in my room. From time to time my moniter would cut of and I would have to wiggle the blue cord to get it back on. After A while the moniter didnt cut on. I thought i could replace the display adapter easy or install a new graphics card but I couldnt. They said I would need to replace the whole motherboard. Well I had money at the time and I wanted to upgrade my computer to plsy Countet Strike:Source So I bought the new video card. Some workers said that i would reconize it and i wouldnt have to replce the moher board but others said did need to replace it. So it didnt reconize it so I got a new mother board (Same exact one) but I still have this problem I boot up my computer and the screen light id on but it stays blank. My dad was saying maybe I zapped te motherboard which imsure i didnt because the mouse was working when i plugged it in. So anyways I had money add te time I wanted to go on and upgrade my computer. I bought s 450W power suply and a nvidia geforce 6200. Now as time passed i hin i figured out the problem. My processor wasnt working. I did not here any type of beep in the beginning of the boot. So I try aking the processor out another computer and see what hapins. I guess I was right tha exact computer was doing the same thing. So now Im try to get another 512mb ram stick and a better processor for my computer. By the way I have an hp pavillion a 287x(http://h10025.www1.hp.com/ewfrf/wc/product?product=344623&lc=en&cc=us&dlc=en&lang=en&cc=us) And I would like to know if their is anyone out their who could help fix this problem.

Just guessing here, because of limited information, but you changed the motherboard while keeping the hard drive as installed with HP software?
If so, Windows has determined that you have made a major change, and no longer have the eeprom that has the HP Pavilion Tattoo for that model.
So it won't boot due to not having an official HP motherboard. Don't blame HP, this is a Microsoft issue.
Microsoft's official position is that the operating system dies with the motherboard.
Windows is designed to detect any changes to hardware configuration, then will usually refuse to start.

Other causes:
Bad memory, bad hard drive, bad video graphics port, bad power supply will all cause these signs and symptom.s

hps are notorious for bad power supplies so are e-machines. Replace yours before doing anything else.

But since Sam =) reports that he has replaced the power supply with a 450 watt, perhaps the problem is elsewhere.
Since "they" said to replace the motherboard, he Sam =) did so, it might be helpful to know more about this advice... and whether a board was obtained from HP, or other details. Also, how did he determine the processor was not working?
What has been done to diagnose memory, video, processor, power switch, hard drive?
