help!

[voytex]

i have a pavillion pc i dont know what model it is and installed a gpu so i could play games. but after a month or two while i was playing fallout 4 it freezed and i couldnt close it down so i restarted my pc and when it started booting up i noticed that there are some green boxes and lines and after the hp logo my monitor would just go to sleep and telling me that it has no signal. 

 

but when i used the onboard graphic it booted up just fine with no errors so i installed the gpu again and it did the same thing the green boxes and lines and after the hp logo the monitor would just lose signal. and when i enter the bios settings it just says 'no boot disk detected or boot disk has failed'

 

please help i really need my pc coz thats where i do my homework and stuff and for casual gaming too.

I assume you checked that all of your connections are good. In that case maybe your graphics card is faulty? Try to RMA it then.

another issue could be the PSU not being powerful enough, a lot of tier 1 OEM PSU's are absolute crap for expansion and won't actually output the power that they are rated for if it was even supposedly powerful enough in the first place.

I've had this problem back when I still had a pentium 4 pc. Your graphics card is probably not properly installed. Just push the graphics card into the slot firmly, then boot the computer. (by "not properly installed" I mean that it seems to be fine, but doesn't work.) sometimes, it helps to re-install your gpu.

I had this problem a couple weeks ago and I tried everything from reinstalling drivers with DDU to reseating my graphics card. Turned out that when I had to force shut down my PC from rainbow six siege somehow windows on my SSD became corrupt. I did a windows reinstall, keeping all personal documents, and I have not had the problem ever again.
