Issue:
There was no problem on displays but I had to move the computer so I turned it off, moved it, and connected everything back. Only one of the monitor ports work now, but I've always used two monitors for this CPU. The CPU has the following ports: 3 display ports (DP1, DP2, DP3), VGA, DVI. Previously the monitors were connected to DVI and DP3, but now only DP2 works. Connecting it to anyonther port doesn't send signal to the monitors.
DP1, DP2 and VGA are all mounted on the motherboard. DP3 and DVI are on a graphic card or something. To connect to a DP I use a DVI to DP adapter.
I have 3 different monitors with me and I tried the following combinations:
Drivers:
The drivers I've checked to see if they were updated: Communication Port COM1, PnP generic monitor, AMD Radeon HD8570, graphic card VGA standard.
System info:
CPU Dell Optiplex 9020
Intel i7-4770 3.40GHz, 16GB RAM
2 identical Samsung 27" TV, BenQ GW2750
PS: the transparency of the taskbar and windows of the windows 7 theme (Aero I think it was called) also stopped working. Changing the themes hasn't solved the transparency issue either. I don't know if it's related to the no display signal or not, but it happened at the same time.

- BenQ monitor: DP1, DP2, DP3, VGA, DVI. Only DP2 works.
- Samsung TV2: DP1, DP2, DP3, DVI. Only DP2 works.
- Have tried connecting different combinations of 2 monitors or all 3 monitors connected at the sametime, but only the one connected to DP2 shows anything. Restarting CPU, turning off and on CPU, unplugging and replugging the power cord hasn't solved the issue.
