Hello everyone,
Several Acer Aspire TC-886 computers were purchased for the enterprise.
For production needs i have installed more powerful PSU 600W with a 6-pin output for powering the video adapter. Discrete videocard was installed in the system unit.
After the videcoard has been inserted into the pci-e connector, the computer turns on, the built-in speaker signals that the board has passed the post-check and the sound of turning on the system is heard from the speakers, but the image does not appear on the screen.
Not a single "serious" video card has started. Only the Nvidia GT-710 pci-e 2.0 was started without 6-pin and Nvidia GT-630 also without 6-pin too. Later, when i turned on the system on the integrated graphics adapter, i found that the drivers for all the video adapters i inserted were downloaded from the windows update center.
All “serious” videocards not working and for some reason does not display an image on this motherboard.
What i tried:
I updated the BIOS from Acer website, now there is a version: R02-A2 — nothing has changed.
I installed various video adapters with 6-pin and without, Radeon (HD7750, HD5570, HD6870 etc.) and Nvidia (Quadro600, GTS450 etc.). Only simple low profile GT-630 and GT-710 were launched, as i wrote above.
I inserted various PSU with 6-pin connector (500-600W).
I tried it not on one specific machine, but on several, the problem is still the same.
I tried it on several displays and used D-SUB, DVI and HDMI.
I hope for your help and support. Thx!
