Hi there, 

 

since a little while when im gaming and watching video i have black screen on both monitor saying no signal. When this happen, i lost control to everything. I had to restart the computer. I dont know what is the problem. I replace my evga 3070 to be sure nothing is wrong. I put thermal paste to be sure on the CPU. I did some test heaven benchmark 4.0, cyberbench, mem86test and well no red flag. But the black screen continue so i dont know what to do. I have a new cat and shes been chewing the cable. I did replace all of them except one the power cable of the power suply. I will change this one very soon. But if the problem continue do you guys have idea what is the cause of the black screen ? My updates are good too. 

 

Thx a lot
