POST passed, no video

About a week ago my computer shut down unexpectedly. When I tried to power it up again the power supply would start up the fans for a moment but shortly after it would shut down again. I trouble shot that problem and eventually decided to replace a bulging cap on my motherboard and that brings me to where I am now.

After replacing the capacitor my system starts up with all my hardware connected (2 sata hd's, 2x512 geil mem, geforce 6600 card, ide cdrom) I get a correct POST beep but no video signal.

I've tried reseating the memory and video card several times as well as trying all combinations of using one and both sticks of memory. I have cleared the cmos and tried to start up without a drive connected but nothing has changed.

One thing I've noticed, the video card gets hot after running for awhile, while I don't notice any change in the cpu's heat sink.

I guess I'm just looking for some advice as to what to try/replace next. The motherboard is of the Asus socket 939 AMD variety.

Look into

Besides the obivous bad cap, its good to change a bank of caps that follow or within that circuit path/area. Reseat the video card several times and retry powering up again. Understand, what made that bad cap could also have secondary problems. When it comes to such, repair as best you can, but if no good results, replace the mtrbd.. For the amount of time and/or effort placed into a mtrbd. repair., time saved by replacing can be a tipping point, return the system back to service. the choice is yours.
