You will probably need to give PCS another chance to fix it before asking for a refund. They have legal rights like you do and one of them is being able to repair the fault in a reasonable time. I suggest you ask for another RMA and point out that if this doesn't fix it then you want a refund.
I wouldn't bother with the same generation (20 series), they weren't that good anyway. A 3070 would be my choice but you could also look at AMD. Nothing is cheap anymore though. No need to worry about power requirements, that's a top spec PSU you've got.
Could be the graphics card. That's why I keep a cheap second hand 730 for just such an event.
To eliminate the memory have you tried my suggestion earlier?
Check the graphics card connections are OK (including motherboard connection). Check memory is seated OK.
Next try moving the memory to a different slot and just use 1 stick at a time.
If you have another graphics card then try that as well.
Finally contact PCS helpdesk if no joy.
So does this mean I might have to turn my heating on when not playing cyberpunk?
Nvidia bragging about 3 slot graphic cards being slightly less power hungry is hardly eco friendly.
I assume you have the volume turned up and done a troubleshoot. Click the speaker in the taskbar.
Also look in windows settings -> sound control panel. If there's an option for Realtek HD audio 2nd output then make that the default.
I would agree with this summary. For gamers at 4k (and a good few 1440p) the bottleneck is the GPU so best to throw the money at that rather than the expensive new motherboard/memory/cpu combo that AMD are now launching.
You say the problem started before you added memory. If so, remove the old memory and run on the new 16GB only, and see if it fixes it.
After that you need to try alternate devices to the ones installed. Really you need a donor PC for this including monitor, keyboard, mouse etc.
Yes, but I'd rather have a car at number 20 than number 1 etc.
Generally it means the chance of it costing you money (and the value of the bill) increases as you go up the list, as insurance is all about chance.
FYI carwow did a video if you want to avoid the sun article.
I use 1080p and it's fine. Not blurry at all and I'm at 27 inches so it aint small either. OK so my eyes aren't as good as they were but no way can you see pixels, even close up. I think you have a faulty monitor.
You could use ethernet by getting plug-in adapters that use your electricity circuit. I've got Netgear powerline but there are cheaper ones. My wifi was running like yours at around 4Mbit and intermittently dropping out, but with the adapters I get the same speed as if I was plugged directly...
Most games give you the option during installation (don't choose default installation). Then just browse to your 1TB - probably D: drive. I create a folder called Games in advance on D and then browse to that during installation.
If you've already installed on C then you will need to uninstall...
