Computer not showing anything or staying on

[Minitar9898]

So I took my old pcs gpus out dual gtx 770s old I know but his PC is special to me as it was my uncle's and given to me when he past away a few weeks ago and I took out the cards to clean them and after putting back in the screen shows nothing after turning on and the light days LED VGA and the system now won't stay on for long I don't have really any money to spare on parts either but it's imperative that this system or at least case stay running it means the world to me as me and my uncle bonded through gaming and it's all I have left any help is much appreciated

You repasted these GTX770s? Was the paste non conductive?

[Minitar9898]

I didnt open the cards I just took them out to dust them off better

Do you use SLI bridge and did you connect the monitor the same output that it was before?

[Minitar9898]

I do use sli and yes

I'm assuming you have attempted to re-seat both GPUs and the bridge? Attempt to start without the bridge? Does the CPU have onboard graphics? Attempt to boot without the GPUs all together?

[Minitar9898]

I'll try that

No onboard graphics

As in, your CPU doesn't support onboard graphics or your computer isn't displaying onboard when it should? 

 

Have you done the other troubleshooting steps I suggested?
