My Graphics card Don´t show signal on monitor

[-Kharma-]

So, basically this happened, I recently bought a gtx 1050 (75W) and installed it on my pc, and worked fine, I played some fallout 4 and cs:go, and I installed the drivers, and then I decided to install NVIDIA geforce experience, and when hitting on create on create account, the signal went off and the GPU fan started spinning at 100% and I got scared so I turned off the PC , then I booted it up and it just showed my motherboard (Gigabyte) and went black, so I turned it off again and booted it up again and I got no signal, What should I do? What´s the problem? I migh think that the power supply got bad or something like that, I tought it was my mobo, so i installed a gt 730 and it worked fine.
I have a celeron g1620 at 2.6 GHZ
gtx 1050
Gigabyte ga-h61m-ds2
Generic power supply of 500 watts
and 8gbs of RAM

Generic no-name power supplies are not recommended. They usually heavily weight their wattage on the +3.3v and +5v lines where you don't need it and the +12v line has a low wattage value where you do need it.
