    startup procedure of graphics card or MB
    by harp
    I have a one question about startup procedure of graphics card.

    On graphic card Gainward GF9500GT 512M (in attach) I do basic passive measurements, diodes, mosfets, fuses, some resistor, rails... on gpu is about 3 - 4 ohm... but else nothing is shorted.
    I plug card into MB and boot up. Splash screen and boot text was appear only on integrated vga on MB, and after about 10 seconds the MB shutdown itself. There are no switching to external graphics card (that I inserted). I try another time and it is all the same repeating, after 10 seconds MB go off.

    I do not any...

    ECS MCP61M-M3 Chipset gets hot when Graphics card is pluged
    by caspian
    Dear Forum Members,

    I have an ATX mainboard: ECS MCP61M-M3 with CPU: Sempron 140 and Chipset: MCP61.
    If I use only the Onboard Graphics, the Chipset's temperature is about 52'C.
    If I use a PCIE x16 Graphics Card, the Chipset's temperature is about 70'C and tends to go higher. But the Graphics Card's temperature is normal.
    In both the two cases, the PC works fine.
    I have tested two different Graphics cards and it gets hotter with both of them.
    Any idea why it gets hotter with Graphics Card?

    Thanks

    Asus rog strix rtx 2060s a8g graphics card turns on and does not give video
    by Rhaverz
    Good afternoon friends, I have the same problem, the equipment turns on, when I connect it to the equipment and without connecting it to the HDMI or Display port with the integrated graphics of my equipment, the graphics can be displayed in the device manager with an error 43 but even if I try to update it "manually" it manages to remove the notice but it still doesn't work.

    If I connect the graphic with the HDMI or Display port, the equipment turns on but it makes a long and 3 short beeps and does not give video

    I thought that the BFDJ USB-C or MP8858GQ...

    Schematics and boardviews for newer GPUs (RX VEGA 56/RTX 2080/RX580/ZOTAC RTX 2060)
    by Borges
    I have been learning about microcomponents and GPUs for a while now to make an attempt to fix a few GPU I have bought from eBay.

    For some older model I have started making some repairs as it has been easier for me to find the schematics and BoardViews' for modle sbelow gtx 1080/rx 480. However I have a few GPUs I have bought that I am having a hard time diagnosing or finding any schmatics/boardviews. These are the following GPUs that are giving me a headache:



    - GIGABYTE Radeon RX VEGA 56 GAMING OC 8G
    - GIGABYTE GeForce RTX™ 2080 GAMING...
