HP and Compaq Desktop PCs - BIOS Beep Codes
This document pertains to HP and Compaq Desktop PCs. It is normal for the computer to make one or two short beeps during the startup process or during a BIOS update. Let the process continue and do not interrupt it.
However, if the computer beeps and Windows does not start properly, a more serious hardware problem exists. The most common problems that cause beeping sounds are:
-Memory and heat-related failures caused by a build-up of dust in critical cooling areas
-A keyboard key is stuck
-A memory DIMM or hard drive cable is not seated properly
-A component on the motherboard has failed
-A basic computer function was unable to start
Make sure the Ti is properly seated and the RAM is seated correctly as well. If problem persist then remove 1 RAM stick at a time or if you only have 1 stick, move it into another slot.
You could also try to update the BIOS but try this ^^^ first.
