[paulsoarece]

Hi , i bought a new motherboard for my pc and it didn't fit in the case so i put everything back together by the way the computer was working perfectly before all of this , and now whenever i try to boot the pc everything spins everything fine but the motherboard gives me 4 beeps and no display .
I looked on the whole internet and i tried everything .
All the parts are perfectly fine but i get no display and 4 beeps .
Guys if you have any ideas please some because i need to solve the issue .

google the motherboard model number and "beep codes".
the 4 beeps signify a specific problem the motherboard is having. what the 4 beeps signify will vary depending on who makes the BIOS/UEFI on the motherboard.
google the model number and beep codes and you should find your answer

i already know that is system timer failure

if memory servers the system timer failure is also grouped with a RAM error in bank 1.

disconnect all power and remove the battery from the motherboard for a minute (60 seconds). replace the battery and power and see if clearing the CMOS was effective.

Verify the RAM is fully inserted. try the RAM in differing slots.

the system timer is an IC on the motherboard and if has failed you will need to replace the motherboard.
