We would like to inform you that 4 beep codes are related to graphics card or motherboard failure most of the times.
Here are our recommendations for this issue:
- Clear the CMOS battery for 30 minutes.
- Test the system out of the chassis, unplug the power cord, remove all non-basic components, connect the power cord back in and try to boot up the system. If problem does not take place, try installing the other components one at the time until you find out which is the conflicting one.
- Remove all memory looking for beep codes.
- Test the system with a different graphics card if possible to narrow the issue properly.
