hi there, ive met some problem.
i was installing both win7 sp1 upgrade and amd graphic card driver (an old version of 7/2016) at the same time. then i went to sleep. when i woke up i found the black screen.
so i
1. moved the mouse around and tried to wake up the pc if it's in sleeping. -- didnt work
2. checked the power supply of the monitor to make sure they are connected well, and restarted the pc many times. --didnt work. screen remains black and it kept saying "no signal", even after i heard the starting music for windows.
3.re-pluged in the hdmi wire on both sides -- didnt work
4.changed the power supply wire for the card -- didnt work.
5.re-pluged in the card -- didnt work
6. switch the hdmi from my G-card to mother board. --- everything else went back to normal ,except the graphic card.

graphic card was there all the time. it works normally b4 i went to bed. i didnt even touch the pc during the process. things like this still happend. that makes me feel so confused.

i tried to check the statics at bios, but the card wont be detected.

another clue might be important is my 390x card has a turbo or booster button. normally when someone pushed it down, the button should turn blue due to the led. but it lost this function as well.

this card is old. maybe already 2 years. recently my PC did crash a lot, and "graphic driver stopped responding and has recovered" happend very often.

im my judge i think it might be some pard of the graphic card is broken. but im not 100% sure. and there's no other pc or graphic card around for testing. so what do u guys think?

edited: r9 390x can handle most of these top games pretty well. in fact i never tried to overclock or to change its volts. but it did have "graphic driver stopped responding and has recovered" problem all the time. at first it happend very rarely. it's so sneaky i thought it might just be some system problem, amd card after all, right? but this stop responding thing start to occur more and more often in recent months. eventually it turned out to crushes. but i was still not sure if it's the card problem, many ppl complain the same problem on the internet, and ascribe it to windows 10 the system. that's why i was changing back to win 7. but my card "died" half way lol.

entire PC specs? It could be a couple of things, I very much doubt the card is dead unless its very old (2 years is not old) anyhow, going to far in volts on a GPU is very hard, you have to literally try to put to many volts to break it so its very unlikely. If you have dedicated graphics on your CPU, try removing the GPU or just plugging your monitor directly into your motherboard and downgrading the drivers to the previous version, Then install the GPU again and plug the monitor back into the GPU, Make sure all power cables are properly plugged in. Try this and get back to me.

finally the graphic card R9 390x

thanks for advice. but ive tried this. sorry didnt mention this above. i uninstalled all the drivers. but the situation remained. it seems drivers dont have much to do with it. it doesnt even show bios settings. it shows nothing when connected with my 390x
