Question VGA Light on, no display.

[FeddeAzerty]

I woke up this morning and tried turning on my pc and I wasn't getting any display, my pc was working just fine the night before. Last thing I was doing before turning the pc off was watching TWD, didn't touch BIOS settings or anything.
Things i have tried:

1. Resetting CMOS battery
2. Try booting up with 1 stick of ram
3. Use a different GPU ( I tried using my old GPU and nothing LED on no display)
4. Trying inserting GPU on different PCIe slot
5. Try to see if i get any display on another monitor
6. Swap psu cables

PSU is new (3 months old) and cables seem fine to me and they are properly connected. Other than the VGA light PC seems to post just fine, I don't have onboard graphics to actually check.

Components:

• RYZEN 7 2700X
• MOBO: MSI B450 PRO CARBON AC
• 6900XT/ RX 580 8G(OLD GPU)
• RAM: Corsair Vengeance Pro
• PSU: EVGA Supernova 850gt

One of the following, or all of them are dead: CPU, MoBo, RAM.

Here, you'd need 2nd, compatible PC, where to test out each and every component individually, to see what died.
If you don't have 2nd compatible PC and/or doesn't want the ordeal of hardware testing, haul it to PC repair shop and pay them for diagnostics and fix.
Probability of what is dead: MoBo - likely, RAM - maybe, CPU - unlikely.

I don't have a 2nd PC to test my components out, I tried only booting it up with the newest sticks i bought (3 months old) and nothing. This is so unfortunate, how does my mobo suddenly die?

Does old RAM work in your system? E.g using ONLY old RAM, preferably only 1 stick.

 

[FeddeAzerty]

No it doesn't. I have tried everything I could find on the internet lmao.

Hardware can and will die on daily basis, often without any reason what-so-ever. For that reason, there is warranty. If no hardware ever dies, there wouldn't be a need for a warranty.

So, best option is PC diagnostics at repair shop. Most likely a faulty MoBo, but can be other component(s) as well.

I wouldn't be able to get my pc checked at repair shop so i just have to hope, the mobo is whats died. Do you think the r5 5600x is good for 1440p? (6900xt)

Do you think the r5 5600x is good for 1440p? (6900xt)

If the GPU doesn't hold the CPU back, then R5 5600X can push ~130 FPS on 1440p,

To me, personally, anything above 40 FPS is good. Btw, i game on 1080p.

i have a 6900xt and 240hz monitor i mean tbh i think it will be good enough
