Computer not booting after cleaning.

Tbid · 3 Mar 2013 at 15:25

Today I took the sides off of my computer case and cleaned the inside out with compressed air.

Once I put the sides back on and reattached all the peripherals and turned on the computer it powered on and all the fans spin but I don't get any video out.

My mobo is an Asus p67 Sabertooth, I have an i7 2600k and 2 x Gtx570

The CPU_LED is lit.

I've tried re-seating the RAM but that hasn't achieved anything, I've also tried the MEMok! Test which results in the MEMok! Led lighting up and not much else happening.

Any ideas on what to do next?

If I haven't provided enough information please ask for what I should provide.

Do you recall knocking anything?

Do you have an on-board graphics you can use?

No onboard VGA unfortunately, I don't recall knocking anything either.

Any more recommendations short of taking it all apart and putting it back together?

Recheck all of your connections and try reseating the GPU or booting with only a single GPU.

I'm also not getting any beeps from the speakers so I can't identify what the problem may be related to, I think the speaker itself rather than the motherboard is broken as it has worked fine without issue for about 6 months, just without the beeps.

When you cleaned the PC did you remove any of the components?

It does sound like RAM is not being detected.

When you disconnect the monitor cable from the graphics card do you get a no signal detected message on your monitor?

Did you hold the can in an upright position? Compressed air will discharge a liquid substance if not used correctly.

I'm not implying you don't know how to use it BTW!

try reaseating your cpu cooler/heatsink,dont disturb or take out the cpu just remount the heatsink and see if the cpu led goes out at boot up

Hi, just make sure all cables , etc, are connected properly and Memory, GPU, Soundcard are seated properly and clear the CMOS, read your manual on how to do this.

I've just removed everything from the case, taken my cooler off and resat the CPU, as my speaker isn't working so I can't hear the error codes if there are any. I'm a bit stuck on what to do.

As it stands now the computer powers on and the CPU_LED illuminates red solidly.

I just remembered that when I first received this motherboard it had exactly the same problem that it has now and I RMA'd it to OC for a replacement, that was in June '11, am I still within the time frame to RMA? I see that on the OCUK website there isn't support for asus motherboards over 12 months old to be RMA'd what can I do?
