Dismantled Cleaned Rig - No Output on Monitor

[Ae0lus]

So I had a dodgy fan on my Kraken X61 radiator, which was sounding very beat-up and sluggish.

 

One day last week I got the "CPU fan speed error". I dismantled parts of the PC and purchased some compressed canned air to clean out the rig. Turns out the other fan on the radiator, was never plugged in as I could never find an additional socket. So I swapped them over and voila the fan was spinning again.

 

But, I had a problem... the screen was not responding with no output once I had loaded everything back-up. Now I'm concerned that I placed the canned air too close to the GFX card and introduced humidity.

 

I want to run through a check-list if possible of troubleshooting, of what some experts would do, in order to clarify the issue. It might even be something very simple, but want to understand the best way to trouble-shoot so that I'm not stabbing in the dark.

 

Failing that, do I have a leg to stand on with any kind of warranty with the graphics card? It was purchased 17 March, 2016.

 

Also, I don't have a speaker hooked-up to my desktop, so unsure of how I can hear the POST beeps.

if you removed the ram you might want to try reseating it can sometimes cause boot issues

I haven't removed the RAM. But, might of been unseated with movement - will check this.

 

I mean please let the suggestions keep coming. As I'll most likely run through them all after work today.

If you oc the graphics card you can forget the warranty

First thing I would do is to try to boot without the graphic card. Use the video out from your motherboard.

You probably just need to reseat the graphics card.

Take it out and put it back in, but make sure it snaps in all of the way.

Sometimes they can look like they're all the way in when they're not.

Don't push too hard though of course. 

 

Oh, and make sure you plugged the PCIe cables back into it and make sure they're still plugged into the power supply.

 

I really doubt that the can of air harmed anything though.

Even if some humidity got to it, you likely didn't start it right away so it had time to evaporate.

No it's not oc at all.

 

Thanks people, I'll give these attempts a go. But, I'm grateful that it doesn't sound as drastic -fingers crossed-

It's much more complicated than that:

From what I've gathered on the subject, it doesn't void the warranty as long as you don't modify the card's bios by flashing it.

If it's within software such as MSI afterburner or Asus GPU Tweek II, you're not voiding the warranty.

 

It wouldn't matter anyways.

Just don't tell them you overclocked it when doing an RMA just in case and they'd never know anyways  

I actually did tell Asus that I overclocked my strix the last time I had an issue with it and they were willing to RMA it. I didn't end up doing it because I solved the problem on my end, but overclocking it didn't seem to be a problem for them.

Good to know, how long are warranty usually for graphics cards?

It depends on your card. Usually, there's a little card in the box telling you how long the warranty is. 3-5 years though on average I'd say.
