I woke up this morning and decided to clean my PC as I always do with a can of air to dust it, made sure none of the liquid came out, I don't tilt the can. I also used a brush to brush fans clean and other components. Then when I hooked it up again the PC would not respond to the power button, I unplugged it and made sure everything was as it should be connection wise and tried again, still nothing.
After pressing the button a few more times it turned on but the PC didn't post, no beeps, everything else had power but the HDD activity light stays off too, I hear them spin up though. The light on the MOBO (phase LED #1) comes on, but doesn't budge from there. When I press the power button when it's on it turns off and doesn't come on again unless I press the power button many times.
I also noticed the PSU makes a buzzing noise while its plugged in, on or off. No burning smell.
I'm about to go get a PSU to see if a new one will fix it, but would you guys have any ideas on what it is? Do you think in the process of cleaning something might have happened?
dismantle all your parts and then assemble again . maybe you accidently did something wrong
Thing is I didn't dismantle anything other than taking out a couple fans to clean the blades, their connectors didn't come loose or anything. I double checked the 8 pin and 24 pin MOBO connectors and they're in fine, I tried to turn on the PC without the RAM but it just doesn't respond to the power button unless I try many times, even so like I said it just sits there, no POST or beeps.
Well that could just be Coolmax which should be avoided, then again reseating everything and if no help most likely motherboard if you can confirm either of the PSU's works.
Yeah I'm returning it, I just wanted to see if it was the PSU. A man at the PC parts store hooked up my Corsair to a tester and it was reading 4volts where it should be at 5volts and it also didn't respond immediately when he flipped the switch.
I took out the RAM and turned the PC on and no beeps or anything. Switched RAM to another pair I had upgraded from a while back, still nothing.
If you have a mobo speaker and no beeps likely bad board if it gets that far in the boot cycle!
Yeah figures, it turns on, HDDs spin up, Phase 1 LED on MOBO lights up, and nothing. It has speaker because I've heard it beep.
Well it might be that both PSU and MOBO are bad I guess. I'm gonna have to hit up Newegg and look for Sandybridge mobos they might have left over.
