Help please - no signal!!

[Brandi93]

So everything was working well, then I tried installing windows 11 and when it restarted, no signal on my Samsung TV.. 

 

I actually took out all the pc and re assembled it on a cardbox outside the tower but nothing. Reseated the Bios battery for nothing as well. 

 

Tried plugging in the ssd I installed windows 11 on a laptop and laptop worked fine! No problems.. 

 

All fans and LEDs spin and work but no signal on TV. 

 

Tried hdmi with xbox one with TV and it worked so it's not a cable issue either. 

 

I'm really really really frustrated I don't know what to do :(

What cpu do you have? If it has an igpu check if it works through a motherboard port with the graphics card removed. Try with one ram stick at a time if you have multiple. Also make sure the bios is reset. Removing battery will do this but will take about 15 min without the battery. Shorting the cmos reset pins while everything is turned off resets it instantly.

Looks like you have onboard graphics? I would try removing the GPU and running onboard to the monitor.

 

I am thinking that for some reason maybe Win11 isn't playing nice with the GPU drivers. Or needs to go through a reboot-or-two before it picks them up. Or just need to uninstall drivers.

 

Also, this is a stretch for most people but is RDP enabled? If so, let the machine boot and try hitting it through RDP from another device.

It has Intel UHD 630 onboard graphics. The problem is motherboard has only vga and dvi and although I have old monitor that takes Vga I'm not sure it works anymore. Already tried it with it but no signal as well on the monitor, but as I said it could be the old monitor. 

 

Gpu is not the problem, I tried both the gtx 1080 and r9 270x both no signal. 

 

Reseated ram a lot of times, tried running with 1 module and changing it up, no signal. 

 

Even removed cpu from socket and re installed it, no signal. 

 

At this point I'm thinking it's the motherboard? I don't know. Its very hard to tell but what else could it be? 

 

Power supply maybe then? Not giving enough power? 

 

At this point I'm really desperate, I might just get a second hand old gaming pc now,
