PC not outputting any signal to monitors

[Cactusman24]

I’m need of help and never been here before. 
 

My brothers pc recently started randomly restarting and the psu fan would spin up. When I tested the pc, it would just crash entirely. We unhooked all the cables took off the side panels and blew out a lot of dust. Now when we power it on, it looks like it posts but it won’t display anything to the monitors and it sounds like the fans are running at full speed. 
 

The Specs of the machine are as follows:

Cpu: Core i7-7700K

Gpu: Nivida RTX 2070 Super

Mobo: Asus B150- A

RAM: 16gb Corsair vengeance (unknown clock speed)

PSU: thermaltake  700w 

There’s also 1.5tb of Samsung ssd space and a 4tb Seagate hardrive. 
 

Any tips on how to resolve this issue would be much appreciated. 

Thank you

Try reseating your ram and also try booting with only one stick and also try booting with no GPU in from your IGPU to see if it’s the card. If none of that works it could be a bad PSU or a wide range of other issues.

Thanks man, reseated the ram and saw the gpu wasn’t seated properly. Hopefully that was the problem
