Question My PC is having a mental breakdown.

[Wastse]

So my PC which I've only had for a couple of months now is acting up. Whenever I don't have RAM in the slots the pc is fine just no display. However when I DO have RAM in any of the slots the CPU fan will turn on and off periodically. I haven't tried replacing the RAM with new RAM yet but if it doesn't work I just want this to be on here so I don't have to write it later. Any suggestions?

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

It sounds like the system may be boot cycling due to a failure to train memory.

Be sure to always reset CMOS after changing memory configuration, whether changing to a different memory DIMM or even moving the same DIMM from one slot to another.

We really need specifics as to make/model of your motherboard, ram and cpu.
