Good day!
After having been looking the solution on several forums and websites without any success, I've decided to share my problem, in quest of an answer.
Here's the situation:
It all started when I've wanted to reboot my PC yesterday (a game would take ages to launch, not as usual). It turned off but never booted back!
In a nutshell, the problem is:
When I turn the power on, POST starts, with first GPU_LED lighting up and off as it should, then the DRAM_LED lights up before my PC shuts down and restart. This operation repeats itself several times but each time it takes a bit longer for the PC to shut down (1). Eventually, the Xth time, the POST works until the VGA-LED lights up (and the DRAM_LED goes off). That is the last stage it gets to before the PC shuts down completely without restarting. The VGA_LED remain lit for several seconds (5 to 10 I'd say) and then it is over.
Information:
(1) I wouldn't bet on that but I think these first restarts are caused by the MB that determines something with the ram.
I do not have, at any time, any video output
I have checked that each stick of RAM is well seated
I have tried with each stick of RAM individually, it doesn't change the outcome/
I have checked that my GPU is well seated.
I have tried with another GPU and without GPU, same result.
I have tried with my GPU seated in another PCIE slot.
I have check that there is no bent pin where the CPU is.
There is no metal part touching directly the motherboard that should not.
I have tried with the HD's power cord unplugged.
When the POST comes to the DRAM checking stage, there is this weird noise, I will try to catch it and upload it for you to hear it.
Everything was working perfectly fine until the problem came up
I would 98% of the time let my PC on sleep instead of shutting it down so it was since a while my PC didn't shut down.
I apologise for the flaws since English is not my native language.
Don't hesitate to propose something you'd think I already did, I'd rather double check something than missing the solution!
Config info:
For the ram: 2x HyperX Genesis DDR3 4GB (1600MHZ) + 2x Corsair XMS3 DDR3 4GB (1600MHZ)
CPU: i7 2600
GPU: GTX660 (MSI TwinFrozr3)
I've never had any problem of this kind before
If at first I was thinking about a ram stick problem, since the system manages to get through the ram check during POST and that it stops when the vga led lights up (with or without gpu), I really don't know what could be wrong (you'd tell me it is probably the motherboard itself that is dead and has to be changed, but if so, how can it go until the vga checking stage? That is a purely innocent question, only for my curiosity).
Thank you very much for having taken the time to take a look at my problem!
