I have recently purchased the ATI radeon HD 5570 and tried to install it onto my Compaq Pavilion sr1750nx (I have upgraded this computers RAM to 3 gigs and the power supply to 400 watts). My problem is that when I install it and attempt to turn the computer on, everything starts to run (Like I can here the fans) except I get no picture on my screen. Somethings to note is that I use an onboard graphics card and everything works perfectly when I use that so it is not a problem with other hardware not working. If you could help me that would be great! Here are some useful specs are...
Graphics card (The one I am trying to install): PowerColor AX5570 1GBD3-H Radeon HD 5570 1GB 128-bit DDR3 PCI Express 2.1 x16 HDCP Ready Video Card
Computer: Compaq Pavilion sr1750nx
