    Is it a laptop or a desktop? Did you check the power settings to see if it's automatically sleeping or hibernating? Did you try another ethernet driver? You need to provide more information if anyone is to help you.

    @cuteee:

    The problem with that yellow triangle, could be your Modem/Router! Just off the Modem/Router for about 5-10sec and on again and wait till the Modem/Router loaded fully, after check again the yellow triangle is gone! I've the same problem with my Cisco Cable Modem/Router sometimes, which loses the connection to the Gateway. Even set every settings to static, didn't solve that problem!

    Regarding your 'losing' display, that could be the connection of the Video Card in it's slot, which could be solved by cleaning the connector feets of the V-Card with a soft Pencil Rubber and spray a good Contact Cleaner (I use Kontact 61, from Kontakt Chemie, Belgium) into the Card slot used for the V-Card. If you use a MB internal V-Card, there could be a problem with the on Board Video Chip Set!

    It's also possible that's the PSU of the Monitor, dying capacitors! That could be checked by open up the Monitor, then the PSU of it and visually check all Capacitors. If some of that looks suspicious, like deforming of it's top etc., that needs to be changed immediately! Could be done by yourself, just use a new one with the same specifications.

    I played youtube video and the video stopped with creak noise and the computer freeze and I turn off the computer and then when I turn on, the screen not turn on even I try several time, so I change the video card cable from DVI to VGA and the screen turn on.

    I noticed when the screen turn off with DVI cable (problem) Windows 10 not loaded but when I unplugged it Windows 10 loaded.

    What brand and model video card do you have?
    What brand and model motherboard do you have? Can you see any swollen capacitors on it?
    What cpu do you have?
    How much ram do you have?
    What power supply do you have? How many amps on +12volts?

    I do believe pf100 means Watt's instead of Amps!!

    For to get Watts from Volt and Ampere, the formula is: P(watts)=I(Ampere) x V(Volt)! That's even not really correct because the PF (PowerFactor) need to be calculated as well and that PF is 0.8! So the correct formula would be:
    P = PF x A x V

    For to get the A (Ampere) from W (Watts), the formula is: I (Ampere) = W (Watt) / (0,8 (PF) x V (Volt))

    If your Country has 230V power, and your PSU is a 500Watt PSU, the A (Ampere) would b: I = 500Watts / (0.8 x 230V) = 1.75A (Ampere)

    Check the real on your own!

    I have a power consumption of 2.2A for my Computer with 2 LSD Monitors, while the PSU is 500Watts/230Volt!
