NEW PC Stopped working! Help plz

[IDarren95]

I got a new pc recently and everything was fine until I started a game up, while on the main menu my monitors started flashing then everything shut down. Since then when I start my pc up my monitors don't get any signal but everything on my pc lights up and sounds like its working.

Have you tried you new PC with a different monitor?

 

[Vinceptic]

probably not enough power i feel like you need 750W with your specs

I was thinking the same thing but if that was the case wouldn't it just not work at all?

No, it would work fine up until the GPU drew higher loads and then it would cut out or BSOD.

Yea but still nothing shows.

I would suggest an 850W RMx as a minimum.

That's not what you originally said, you need to clarify what the issue is.

That PSU is not going to be enough for the build when the GPU is being run in a game, that much is certain.

I have just noticed:

Memory (RAM)
4GB Corsair VENGEANCE DDR4 2400MHz (1 x 4GB)

Is that correct? It might not explain your current issue but it will cause issues with playing games down the line for sure.

Ah cool just checking. Can rule that out then

 

[IDarren95]

Are you graphics card drivers up-to-date? Just asking asthere are usually frequent updates on new graphics cards.

When you turn on the system, are there any little lighhts on to the right of the RAM sticks? There are 4 little status LEDs to indicate if it's a hardware issue....not sure what they are offhand but you can find them in your manual

I would also just check that the Graphics Card isn't loose in it's slot and that all the connectors are secure as things can work loose in transit....an issue may not become apparent till it's under load

From what I can see there is only one light next to my ram and it's just white.

Have you tried plugging a monitor into the motherboard video output (ie not the gpu)

Not much point as it doesn't have an iGPU so won't be able to display anything.

 

[jamiephillips909]

Have you tried reseating all the ram and gpu ? More so the graphics card sounds like its not seated properly

My bad - assumed (wrongly) that it did have

Yea but that also does the same thing, no signal to my monitor.
