I have 2 monitors, one is 144hz dp and the other is 60hz vga with an hdmi adapter. They were working fine for about a week until today when I restarted the pc, only my 2nd one was working. I thought it was weird so I unplugged it and tried to plug it back in, but then the other one started working. I tried this multiple times and figured out that it only 1 monitor works at a time, and the other monitor stays on 16:9 even though it is 16:10 so parts of the screen are cropped off even after adjusting resolution. Help me please!!!! (ryzen 5 2600 + rx 560)

This worked for some reason. I took out one stick and it booted, i turned it off and inserted the other stick again and it works now. Why is this?

I built this pc about 3 months ago and tested it with a friend's 1070 and it worked just fine, I was able to get past the BIOS and install the drivers. I am still waiting to purchase a gpu, so for now another friend is letting me borrow his RX 560. However, there is no signal when I turn it on. I've tried unplugging the gpu and plugging it back in, making sure its clicked in, using HDMI instead of DisplayPort, changing monitor, and the gpu fans spin and the power led lights up, but nothing worked. The monitor knows something it is plugged into something as when I unplug the DisplayPort from the gpu it turns off the screen, but when it is plugged in, it says "no signal". (this probably doesn't mean anything but when I turn the pc on it says DVI in the top right then disappears.) Is there a way to fix this or is the gpu dead?

I know that the EVGA W1 sucks and am going to replace it in a few months, but will it be just fine for now with this combo?

What will the wattage be though?

Not neccesarily about case airflow, but about the cpu cooler. I intend to use around 3 or 4 120mm fans.

Thank you!

This might be a stupid question, but I haven't found any answers for this, and I want to know if i can use the stock cpu cooler if i get a high end gpu? Example: Cpu: Ryzen 5 2600 Gpu: RX 5700 XT

In Christmas of 2018, i got a 500w EVGA silver psu. I was wondering if that would be enough for an RX 5700 and a Ryzen 5 2600. Most psu Calculators don't have the card listed, as it is fairly new. Its been on my mind for a while, and I don't want to buy a new psu.
