Hi....Am battling this issue for the past 3 weeks... Intel New DP55SB MB, 750W PSU, Radeon HD 7750...not booting...concluded to RAM module as post 80h code is 28... Used Kingston KVR1333D3n9/2g-SP RAM to no avail...still three beeps. Please assist
This kind of issue happens when the memory is not totally compatible with your system.
Stating from this generation of processors http://processormatch.intel.com/CompDB/SearchResult.aspx?BoardName=DP55SB http://processormatch.intel.com/CompDB/SearchResult.aspx?BoardName=DP55SB, the memory is being handle by the chip, so it is required to use the correct memory type (speed). Please let me know which processor are you using?
These are some recommendations for this issue:
- Test the system out of the chassis, minimal configuration please. (Motherboard, processor, power supply, 1 memory stick and video card)
- Remove the CMOS battery and leave the system without it for about an hour. Then put it back on and restart the system.

Thanks Silvia for the reply, but unfortunately your options did not work.
For all those who were or was battling the same issue, the solution is to update your system BIOS to latest version using a CD.Bios update will not work with USB in this motherboard series.
