    I have a HP Compaq dc5750, and I want to use one of my GPUs in it, but my problem is that they are powered, but they aren't dected by any means, thus outputting nothing.

    The PSU is a propertiary shit with 230W 80% rating.

    I have these GPUs: ATI Radeon X1550, Nvidia GeForce GT640, S3 Virge DX

    It's obvious-you need a better PSU.
    Or maybe you have a faulty pcie connector

    This. You may be underpowering them SUBSTANTIALLY... but I also had an HD 7750 powered off 250w... >> @MarcusD, your board sucks.

    Wow, I completely forgot about this thread! It looks like the motherboard was dirty, or there was a loose connection somewhere, because I disassembled my whole computer to the smallest bits, cleaned everything, including the PSU and the motherboard, and the Radeon X1550 worked afterwards. Also, I had to destroy the case, so I could plug a cable into the graphics card (the case is too small vertically to fit the graphics card).
