I researched a new graphics card for awhile (radeon r9 270x msi), and also found it needed a new psu. Anyway, on the day I ordered it, my brother wanted to take a look inside the computer. He took out the graphics card, which I never had done when I looked around in it. Every time we unplugged it from everything else and put it on a table. Anyway, my brother may have been a bit rough with it(GeForce gt 610). Then we ordered new graphics card and psu, and I put the card back in. I plugged my pc in a bit later, and turned it on, and no display. I took out the card again, blew in the slot(As suggested by other online sites) and put it back in. I did not touch anything else in the case in fear of breaking something. Any suggestions? And I will also ask, if this card is indeed broken- once I install the new card and psu, will everything be fixed?
