Question

Computers

Does not display an image, tested everything. Hardware Motherboard: hp z400 processor: xeon e5450 video card: nvidia gtx 960 etc.

Answer 1

1. Check that the screen is on and working - connect to another computer with a different cable
2. Check that the cable is not damaged - connect to another monitor or to another computer.
3. Check that the video card is working - bios should not give errors about it. Also check that the power is connected to it and there is no dirt in the contacts.
4. Try connecting the computer to a known working monitor with a known working cable.
Well, do not forget that the cable must be plugged into the video card, and not into the motherboard.

Answer 2

Of course, vryatli, but try rubbing the contacts of the RAM with an eraser, if oxide has formed there, then it will be removed and the screen will work. Even if this did not help, then you need to pull out one bar of RAM and start the computer on another, if there is no result either, then try the same only with another bar.
