Title: desktop shows no display HP pavilion media ctr m8200nPC
Post by: shashgo on November 07, 2011, 10:26:40 PM

When I turn on the desktop, both the power supply and the processor fans turn on. But thats it. There is no beep indicating successful boot, and there is no display on the monitor, not even the hp logo. What is going on? Do I need a new video card? Do I need to reinstall the operating system. Please help.

I thought it was the graphics card, so I bought a XFX - Radeon HD 4550 Graphics Card from bestbuy and put it in the pcie slot. Then I fired up the computer, but still no display. Shouldnt I have some display? I checked the power supply. It delivers a max of 300W. Could the power supply be too low in power? All the fans and leds and everything come on though.
What should I check next

no there is no display at all.  What I noticed is there is no beep that indicates succesful POST, so that means the computer is not going successfully throu POST.  Is that why there is no display

Does your monitor turns on(green/blue) without display or just orange?

Attache a PS/2 or USB keyboard before booting PC. About two minutes of pressing power button, Check numlock if it responds.
