PC Only Boots With One RAM

[leothebolter]

I’ve recently had some issues with my pc (specs below) that I’ve miserably attempted to fix and used all my prior knowledge to try and resolve, to no avail.

My computer wouldn’t boot into windows and instead it would start up and give no signal to my monitors (black screen). I scoured the internet for solutions and found lots of different ideas, some helpful, others not. This is what I have done so far.

I’ve managed to get into the bios only when using 1 stick of RAM. When I do this, I can force boot (through the bios) onto my SSD and access windows. At this point, with 4GB of RAM, my computer is fully functional, however if I restart it or try to add more RAM it will go back to the black screen. The only way I can get back to the bios is with one stick of RAM and clearing the CMOS.

I’ve took everything off the motherboard and inspected it to look for any burnt tracks or bulging capacitors, I’ve looked at the CPU socket for any bent pins or thermal paste on the pins, I’ve moved the SSD to another m.2 slot, I’ve updated the BIOS. Nothing seems to work. If anyone has had similar issues or any guidance, it would be greatly appreciated as my only next step is to take it to a pc shop and get ripped off by them. Thanks

Hello

Have you tried the other ram in that one slot? It could be the ram slot is bad or a bad stick.. In 2019 Asus admitted there were issues with the mobo. Also what is the clock speed on the ram?

[leothebolter]

Yeah I’ve tried all the RAM in all the slots and they all work individually. And the RAM speed is 2400mhz with XMP and 2133 otherwise. Where did asus admit this as well if you don’t mind me asking?

Not sure whats happening with the RAM running at that frequency

[Bruce]

have you tried disabling XMP?
have you tried the sticks in pairs?
are all the sticks from the same batch? (same Mhz, same CL)

[leothebolter]

Yes the only way I can get into windows is optimized defaults so xmp is disabled, I have tried memory in pairs and yes they are all the same batch, straight out the pack.

[Bruce]

that really only leaves the motherboard as the culprit.

[leothebolter]

I know and it’s quite hard to find LGA1151 socket motherboards where I live, just strange that the motherboard would pack in like that.

[Bruce]

power surge, dust caused a short, age, oxidisation - who knows!

what is the age of the motherboard?
is it possible to get one stick of larger RAM and just run it like that?
maybe not an ideal solution, but a solution none the less.

with only one stick, it works OK doesn’t it?

There are no system drivers shown to have been installed since the Windows installation date so even if the RAM was/wasn’t bad you were always going to have problems in any event, see my canned explanation below;
Once Windows has been clean installed you must then install first the MBs chipset drivers, then the storage/SATA drivers and third the graphics drivers, the drivers can either come from a disk provided by the motherboard manufacturer or downloaded from their site and saved to a flash drive etc, this is a must and Windows should not be allowed to check for updates before it has been done as more often than not Windows installs the wrong drivers or in the incorrect order and this can cause all sorts of problems.

What is the brand and model name or number of the PSU.

Just a fyi, for the best/most stable performance 2666MHz RAM should have been used and the two sticks placed in slots A2 and B2 which are the second and fourth slots away from the CPU.[/color][/COLOR]
