Hello. Yesterday, I noticed that my PC was under performing, heating a bit more than before. I opened the case, and saw a lot of dust in the case. I cleaned it, but now my PC won't turn on. CPU led is red, and stays lit when turned on. No other led is flashing. I had a similar problem, when CPU led was red, I took CPU out blew on the socket, then put it back in and it worked. Tried that now - didn't work. I check other similar threads on this forum, but I can't find the answer. Any advice on what I can do? I tried to reset CMOS, but that didn't work. All the power should be alright. I don't know wheres the problem.
My specs: 
CPU: AMD FX-8350
GPU: Gigabyte Windforce 760 2gb ddr5
RAM: Hyper X 8gb stick, don't know exact model.
PSU: Cooler Master G550M
CPU Cooler: Cooler Master Hyper 212 Evo
Took out GPU now when I turn on the PC only VGA CARD led stays lit. 
Put the GPU back in after taking out battery, CPU led is back up, VGA not anymore. By the way, can't see anything in the monitor.

only thing i can suggest is to check the cpu heatsink fan is working and is making a good connection to the cpu fan header on the motherboard.

 

might as well check all power cables are fitted correctly too.

Checked power cables, checked fan it's working when PC is turning on. Maybe PSU is [bleep]ed up a bit?

After doing some research it seems these board are having issues coming from the manufacturer. Is the board still under warranty? Have you contacted Asus about your issue?

I have the warranty. But If I contact them  I might need to wait up to 1 months to get my motherboard back....

Gday.

Did you inspect the CPU for bent/broken pins?

Completely remove all the old TIM from the CPU and heatsink surfaces?

Apply new TIM before reassemble?

Hello, Yes I checked if there was any broken/bent pins, but there aren't any. If TIM is thermal paste, then yes I did. Yes I applied new Thermal paste before reassembling. I don't know how do you want me to upload a picture of my broken PC specs if doesn't turn on.. I'm on another PC now.

You computer will need to be running to use HWiNFO64.

It could be a faulty PSU.   Try removing the GPU, power up and see if the red LED goes out.

Without the GPU installed, there is enough "power" for the CPU, with the GPU installed, not enough for both, so looks like the PSU.

As you no longer get a monitor display, can you first try a restart and enter the BIOS, any display? 

Try the GTX 760 in the working computer, to rule it out being faulty.

Can you try a basic GPU, one that does not require any PCI-E cables. 

Can you swap in a known working PSU into the faulting computer.

Not having spare parts does make it hard to troubleshoot.   We would appreciate some feedback on the results of the service test.

Thanks.
