my computer ( Dell intell inside Pentium 4 compuer) does not start

Hello!!

I have pentium 4 Dell computer with widows 2000 operating system. I got a problem with my PC after I have done the following. I have bought an apparatus called Champion which is used for unlocking and repairing cellphones. I installed all softwares associated with the aparatus and I connected the apparatus to the parallel port (LPT1) of my PC. But I made a mistake when I gave power to the aparatus. I gave high voltage AC and it got burnt. (Short circuit is created and it became out of function). At the same time My PC became stuck. I restarted it but it couldn't start. I have measured the output of the power supply of the PC. the meter read nothing. I changed the fuse and when I measured it, it became ok. (12v and 5v dc), But still it couldn't start. what shall I do to correct the problem for my PC please?

First thank you very much for your fast responce. I wanna Callandor's comment to be more clarify. Every PCI cards are imbeded with the mother board. How can I stripping it down and check?

Callandor

If your system has everything onboard and no PCI cards, there's nothing more to check. Otherwise, remove every PCI card, unless it's the video card.
