Windows 10 Professional 21H2, latest patches
Motherboard: ASRock P67 Fatal1ty Professional
BIOS: AMI, ver L3.21A 03/18/2013 (latest available)
Monitor: my large screen TCL television via HDMI-to-DVI cable using the DVI-D (data) connector on graphics card
Graphics: EVGA GeForce RTX 2060 (not "super") PCI-e, 6GB GDDR6 memory, 192 bit bus width, GPU core 300MHz, Mem 405MHz
Power supply (PSU): Gigabyte 850W UD gold
CPU: Intel Core i5-2500 Sandy Bridge, socket 1155 LGA running at 3.30GHz (not overclocked)
RAM: 12GB DDR3 Dual channel, CAS latency 7.0 clocks
Network on mobo is wired (no wi-fi) with Ethernet CAT5e cable to router
Router: Netgear Nighthawk R7000 with latest firmware installed
Modem: Motorola MB8600 DOCSIS 3.1
Internet: Comcast 500MB plan
Self-built computer that's been working perfectly for over a decade. Until the other day I used to have an EVGA GTX 970 video card and Antec 900W PSU. Was working fine with high Internet speeds the other night on a website and suddenly the entire computer just shut down as if someone had flipped the on/off switch on the back of the computer PSU.
Couldn't power it on at all. Mobo has a debug LED that shows POST codes and it was blank. Even CPU fan wouldn't power on. After a lot of trial-n-error I removed the GTX 970 video card and the computer booted up just fine up to the point of POST code on the mobo LED saying "no output device" which made sense. Turns out one of the two 6-pin power plugs on the video card had blown when the PSU blew. That's okay, the card was at least 6-8 years old. Went to a different older video card and computer still wouldn't power on. Took the PSU to get tested and it was bad also. That's okay, it was 11 years old and computer was usually on 24/7.
Took the opportunity to completely clean out the computer of dust and crap, pulled the fan off CPU and cleaned the old dry gunk of both surfaces and put on new thermal goo and reassembled. I was grounded at all times. Replaced bad PSU & GPU. Went into BIOS setup and went through all settings to ensure nothing had changed and hit save and rebooted.
So now I have a new power supply and video card (see specs at top) and Windows booted up after its automatic "chkdsk/f" thing and I get back into everything I have, but soon notice that youtube videos are choppy. And Internet speed tests show I never get more than 50-60MB down but it should be well over 400MB. Using another computer plugged into the router via CAT5e shows same speed test at 500MB or higher. Thus the problem is on my old computer. I tried both of the ethernet RJ45 plugs on the mobo and get same results. I tried different web browsers and get same results. I called Comcast (FWIW) and they tested the line and modem and said nothing is wrong.
EDIT: already ran DDU and fully uninstalled all video drivers, rebooted, installed latest nVidia WHQL driver (only driver not the other crap) so that's not the issue. QoS is not enabled in Windows or in the router:
Help! I need more ideas on what to try and what to test! What could be causing the Internet speeds to be slow but everything else to work properly??
