Boot Failure - No POST, No Video Signal

I tried booting up my Asus P5G41C-M LX motherboard PC last Sunday afternoon, 17th June 2012, and it failed. There was no power-on self-test (POST) nor any video signal going into the monitor. As I do not have an internal speaker connected to the motherboard, I could not tell if there were any warning beeps coming from the BIOS. The only thing that were running are the CPU chassis and power supply cooling fans. The motherboard standby LED was also On.

I was tempted to apply some Electrolube Contact Cleaner Lubricant to the gold contacts/pins of the RAM module but I was not sure if this would help. I do not want to be blamed as I had a similar problem last year with this PC, and it turned out to be a bad motherboard - the store subsequently replaced it for me as it was under warranty. So all I did in the end was to just reseat the RAM module back into the slot. It did not help. The PC still did not boot up.

On the following day, I took the PC back to the store thinking that the worst had happened. The technician did some troubleshooting; disconnected the hard-disk power and SATA cable. It still would not boot up. He the removed the RAM module, took it to his desk and clean it. He then reinstalled the RAM in another slot and the PC rebooted without problems after that. When I asked him, all that he could tell me was that there were contaminants on the the gold contacts/pins on the RAM module.

Perhaps I should have cleaned it myself with the Electrolube Contact Cleaner Lubricant like I did in this previous post on my PCI card. It would have saved me all the stress and worry. Oh well. At least now I know.

Update: 30th March 2015
PC actually froze on the 22nd and 31st August 2014. I coated the pins of the RAM module and memory slot with Electrolube Contact Cleaner Lubricant and have not had this problem since.
