Hello everyone, i have an aspire tc-780 (the one with 8gb ram and i5 7400), the problem is that after replacing the olg gt 720 with a new rx6400 the computer does not go past the acer logo, it doesent event 'beep' and it's just stuck (doesn't enter bios, doesn't open boot menu…); installing back the old gt 720 makes everything work again.

The new video card works perfectly (tested on another pc), bios is updated to R02-B2 (lastest) and it's not psu's fault (i tested with another one), i even tried unpluggin every other component (ssd, wifi module…) but nothing works.

Any idea? Thanks in advance.
