I have been experiencing a strange issue sine the past 3 days.

My motherboard will suddenly stop booting, no beep, but fans spin but i dont get any display.
Even after removing the all the RAM it wont beep...just fans spinning.

Then when i i leave it aside without RAM for a few minutes and try to power on it beeps and says No RAM (thts when i know it will work)
I put all the modules back in one by one and everything works fine until it randomly happens again.

Is the board going to die or what?

I have stock bios on ASUS P5 N E SLI - core 2 quad q6600, 6gb (3X2GB) ram, gtx 650ti boost 2gb, and i have 2 sata hard drives.
PS - i know its very old... going to upgrade soon... just waiting for skylake...need 2-3months

Any help will be appreciated :)

Not sure what you mean by "it wont work at all... but it is working" ? :)

Sometimes reducing the RAM can help id there is a fault with the pins in the RAM slot, however this does not appear to be the issue here. I do not think that it is a PSU issue, as you said that sometimes you can boot into windows by reducing the RAM.

I'm afraid I'm completely at a loss for an explanation here. It could be that your hardware is simply...

Nop nothing in the critical tab...just warning related to time offset in the warning dropdown

Ok, I was expecting event error 41 (kernel-power) or something along the lines of that. Is your computer very dusty/ in an unclean environment?

Yes it was a bit dusty but i cleaned the heat sink,gpu, ram slots with a brush gave the board also a light brush over.
that being said... it could use some cleaning with a blower coz a brush aint that thorough

Definitely give it a thorough clean with a can of compressed air. (Make sure to hold your fans in position when cleaning them, or else you could over rotate them). Try using one RAM module at a time, booting with each inserted module, and see how that works out. It could also be a Q55 error, but I'm just speculating here.

Ya will clean it
I install the modules one at a time always and turn it on then repeat... nothing is wrong although i suspect one out of the 4 slots to be faulty...it works sometimes and some times it doesnt.... not installing RAM in that so tht slot is out of the picture but still its behaving erratically.

Ok, you have to reduce your RAM to 2 slots only. (Dual channel setup, avoiding the faulty slot). Try that, and see if that works. If it doesn't, you're looking a faulty motherboard, or faulty RAM module. Swap out the modules also in dual channel, so each stick is booted in an alternative slot. Keep track of which modules work in which slots (assuming they do). If this doesn't work, it is a fault with the motherboard I'm afraid.

already tried that... all the modules are fine.
Will reducing the RAM help?? how will that matter?
I am also thinking that the board is faulty but it is working now... it is just that it is behaving erratically and stops working randomly... if its dead its dead right? it wont work at all... but it is working

Well i have found the issue and it is that 2 of the RAM slots are behaving erratically ...sometimes they work sometimes they dont

When they dont work, the motherboard doesnt know what to do and it just wont POST or beep.

When it works with the third stick... it continues to work flawlessly for as long as i want, there is a chance of it failing to boot on restart so I just dont turn it off as long as i can.

Everything works fine if i use the 2 other slots.
The solution is work with 2 sticks

At least you found the source of the problem. I think you are in need of a hardware upgrade though ;)
