System won't boot, not even POST or BIOS?
Ok, I bought a new video card and installed it. I previously had an ATI Radeon HD 2400 PRO, and no problems. Now I installed a ATI Radeon HD 4650, and the system would no longer boot. After sevarl tries, I went to look up stuff on the internet and discovered that the new video card I have needs a 450W power supply and a 6 pin connector for the mother board to power the card (which I don't have in my current configuration)
No, when I setup back to my previous setup, same thing, it no longer works. I have tried to remove the RAM, and it will still be able to detect that I have no RAM installed. So everything seems fine, but I could no longer even load BIOS and there is no POST. Monitor works fine, but everything just powers up, fans spin and drives seems to work, but I have nothing on screen and the fans do not slow down like it used to. Because usually it the fans would slow down once POST starts.
so what could have been wrong? anything I might have damage that needs to be replaced?

Well when you installed the ATI Radeon HD 4650, you also installed new drivers. So switching back to your HD 2400 Pro has no effect. The card might be correctly physically installed, but you dont have the correct drivers for your HD 2400. And since you cant even get to the BIOS, means you cant even get to safe mode. So you cant re-install your old drivers unless you manage to log back into Windows. Plus you dont have the required hardware to even run the HD 4650 so thats why you got this problem in the first place. Email if you like, Ill do my best to help.
