PC worked fine last night, turned on this morning to it constantly making 3 beeps and no displays shown, PC and monitor both turn on but doesn't connect.
Made sure the RAM and graphics card are slotted properly and they are.

Any help? Only had the PC for 2 weeks.

@strong sinew I did indeed 🙂 just removed all the RAM 1 by 1 and put them all back in the same place 1 by 1, dont know exactly what the original issue was as everything was slotted as it should've been, but it fixed the issue

Just I am facing the same issue right now turning the pc on and a white light and beeping 3 times I have taken the RAM out and cleaned it and put it back in anything you could help me with??

#

Did you just put 1 RAM in and turned the computer on and then turned it off put the other one in and turned it on and worked??

Yeah I just took the one out, turned the PC on, took the other out, turned the PC back on, then put the first one back in, turned it back on, then the second and back on. You may have to push them back in a little harder than you expect until you hear the click to make sure theyre in properly, but that's what worked for me 🙂

#

Obviously turned the PC off between taking out/putting the RAM back in as well

Check the connections from your psu to the GPU specifically that wire pluggging into the GPU

#

And follow it to where it’s plugged into the psu unplug them and plug them
Back in both ends if you can

Base 64K RAM Failure

There is a failure of some sort within the first 64KB of system memory.

The first bank of memory probably has a bad memory chip in it somewhere. It is also possible that there is a failure related to the motherboard or a system device as well.

Nvidia RTX 30 Series GPUs:
Try disabling CSM (Compatibility Support Module) in your BIOS, and make sure the boot mode is set to UEFI.

ASUS Motherboards:
1 Long + 2 Short: Anomaly detected in RAM.
1 Long + 3 Short: Anomaly detected in Graphics Card.
