PC for Mesa 5i25T

Hello everyone!
I have a problem with installing the Mesa 5i25T card. I have an HP Compaq dc7900 computer. I installed Linux CNC from the official website on my computer, it was without any problems, it works. However, after inserting the card into the PCI slot, the computer will not start, it remains stuck in the bios. After removing the card, the computer works again without any problems. I also tried an HP Compaq 8200, but the same problem. I also tried putting the card in my large computer for drawing, I used a hard drive with the system from previous computers, and the card works. However, when performing Mesaflash, it writes an error: Unauthorized memory access (SIGSEGV). I assume that this is caused by the fact that I installed the system on the hard drive on another computer. The jumpers on the card are set to default. Do you have a tested PC setup on which this card works? Thanks for the advice and greetings from the Czech Republic!

Sometimes updating the PC BIOS can help the issue.
Card testing is done on a H97 or D525 motherboard and I
don't think we have any motherboards that don't work
but I can get a HP 8200 SFF to see if there is a workaround
