Cleaned PC & now my pc won't boot with any graphics card

[jackgourley_]

Cleaned my pc after a year and now it won't boot and I've tested 2 graphics cards with it that has always worked.

Asus M5A97 LE R2.0 Motherboard (very old but using it until I can buy a full new PC)
Main card - MSI AMD R7 370 4GB
2nd card to test - MSI Nvidia N750TI 2GB
CPU - AMD FX 6300 6 core 3.5ghz

I've seen it asked before and when cleaning the PC with compressed air;
I held the fans so they wouldn't spin and created energy.

You only used compressed air and you made sure it was far enough away and you didn't do anything else?
What does it do when you try to power it up?

One thing with cleaning....you can blow debris and it lands somewhere and shorts something.

I've done this.

I believe this may be something that I've done, I'm using handheld cans of air and still did it at an arm's length. I'm just confused if it's the motherboard as the 2nd card which I didn't clean will not boot either.

When booting the PC turns on and there are no LED warning or anything, everything sounds good except I'm getting no video signal.

You have to blow components pretty hard to damage them...and I doubt you did anything even close to damaging them with a handheld can of air at arms length.

Maybe it has nothing to do with the cleaning and it's the monitor or the monitor cable.

Weirdly one of my monitors popped yesterday and it has been sent for a replacement and I'm using my 2nd monitor as the main on now but everything's been fine. I've tried using 2 different HDMI cables and a DVI cable but still nothing. the main cards fans are not running as well now.

Do you think it's booting with no display or not booting at all?

Once I hit the power button the whole system boots, everything lights up aka the graphics card led's, CPU fan etc but just nothing is going to my monitor. Graphics card is lit up and I can feel it getting warm but the fans aren't spinning and it isn't displaying.

"Weirdly one of my monitors popped yesterday "
Are we sure the other monitor isn't popped?

It's fine I plugged in my xbox to it to make sure it was working and it is.

You didn't disconnect anything correct?
Assuming you didn't, I would go into the BIOS and makes sure that it wasn't set to run on integrated graphics...although it doesn't make sense that would change from cleaning it but it's something to check.
Then I might reset the BIOS to the defaults. Maybe the BIOS isn't detecting the cards for some reason.

When cleaning I do take the graphics card out and case fans. If I can't get anything displayed on my monitor how can I get into the BIOS?

" If I can't get anything displayed on my monitor how can I get into the BIOS?
Sorry....my brain slipped.

I would be checking the slot real good with a flashlight for any debris or anything that looks out of wack and I would also really be focusing on the GPU power cable as well.

 

[jay32267]

Is the GPU power cable modular? Did it become disconnected at the PSU?

The PSU is basic and has been working fine with the one 6-pin PCI-E cable all pre-built in the PSU with the other cables. I've tried changing the GPU slot and gave them another blast of air but still, nothing and GPU fans are still not spinning. Tried the 2nd GPU as well which just spins up like a rocket but it won't display to the monitor either. I'm just extremely confused with this now and wondering the GPU slots of the board are broken or not.

Are both cards MSI Nvidia N750TI 2GB?

 

[jay32267]

I would try putting a voltmeter on the 6 pin plug to make sure you have power.

I think it's tending to point towards the MB at this point.

I have caused things to fail by cleaning them more than once.

I've worked on electronics in plants for 30 years. It happens.

You blow some debris on something and it shorts.

It only takes something very small.

That's what I believe too at this point, it'll be my first cleaning up lol I appreciate the help and I believe I'm just going to start ordering parts for my new PC instead of buying it all at once.

Also one last bit of advice that comes from working in plants on electronics for that long. Cleaning is overrated...and as you may have learned, can be more trouble than it's worth.

I've seen many motherboards caked with 1/8" of dirt and oil and still working.

Yea next time I have a Sunday cleaning mood I'm just going to ignore the computer.

Appreciated the help and advice

You're welcome....and I generally clean only when I upgrade...so every year or 2...and just blow it out....and blow it out with the cards in. That way nothing gets in the slots.
