Today I opened my pc,removed the ram just to check the brand and i put it back in but when i turn on the PC,it beeps continuously and shuts itself down,and i removed it and put it back in but this time i evenly pushed with a little force and i again turned the pc on and the beeping was fixed,but the CPU fan only slightly moves and just stops and BIOS detected that the fan wasnt moving (Bios wont let it boot if it does not detect that fan is moving) and it wouldn't boot up
Plis help
Sorry for bad English
