    Most likely I'd say the PSU couldn't cope with the demands of the gfx card, what was previously in there and what spec is the PC? You should try the old gfx card in and see if it POSTs, then try the 4200 in your PC and see if it works. If your dad's PC won't boot with any gfx card then you need to try known good components in there to find the culprit(s). You may be able to tell from the BIOS beeps or mobo LED status if present. You may want to take all non-essential thing out (or unplug them), essentials are: mobo, power switch, RAM, CPU+HSF, gfx card. So basicly what do you get, nothing at all (no fans spin up, no LEDs, no beeps etc) or just a blank screen? If nothing at all then I'd point my finger firmly at the PSU and if that's the culprit it may have taken out many of your other components often inc RAM, mobo and IDE.

    Maybe the mobo is shorting out on the case, or one of the stand off's? try booting it up on a wooden surface with just CPU, one stick of RAM, video card and PSU.

    Don't forget the HSF and the power switch on the case. Try another PSU if poss but if a bare config won't boot then you need to check which part(s) is faulty by putting each in turn in a working rig. Best of luck!
