ok, I cleaned my computer because of how dirty it is, now I removed all the hardware and cleaned it with a brush, after that I reconnect all the parts and when I turned on the PC, nothing. no display, I immediately discharged my self and find the reason why, my first suspect was the GPU, GPU is fine, when I turn the PC on it is heating (so it is alive ??), fan is working. but I do not know why there is no display, so I tried to remove the GPU and use onboard display and it work, tried GPU again and still same result, any reasons why ?
