Count the beep sequence and post it in the forum so that I can view it to determine what is wrong.

Here is a list of the beep sequence and the led lights on the back of the cpu. Maybe get an idea of what I am talking about.
Your computer might emit a series of beeps that identify a problem: for example, one beep, followed by a a burst of three beeps, and then one beep (code 1-3-1) means that the computer encountered a memory problem.

To help you troubleshoot a problem, your computer is equipped with four lights on the back panel labeled "A," "B," "C," and "D". These lights can be yellow or green. When the computer starts up normally, the lights flash. After the computer starts, the lights remain green. If the computer malfunctions, the color and sequence of the lights identify the problem.
Back Panel Diagnostic Light Codes
Normal off condition or possible pre-BIOS failure
Verify that the computer is plugged into a working outlet and that you have pressed the power button.
Possible BIOS failure; the computer is in the recovery mode
Run the BIOS Recovery Utility, wait for recovery completion, and restart the computer to retest.
Possible processor failure
Reseat the processor, and restart the computer to retest.
Possible memory failure
Reseat all memory modules and restart the computer to retest.
Possible expansion card failure
Remove each expansion card individually, and restart the computer to retest.
Reinstall the expansion card(s) one at a time, and restart the computer to retest.
Move each expansion card one at a time to another PCI slot, and restart the computer to retest.
Possible video card failure or bad on-board video
If you have a video card, reseat it and restart the computer to retest. If you have video integrated, you must replace the system board.
Possible floppy or hard drive failure
Reseat all power and data cables, and restart the computer to retest.
Possible USB failure
Reseat all USB devices and cables, and restart the computer to retest.
No memory detected
Reseat all memory modules and restart the computer.
If the problem still exists, to eliminate the possibility of a faulty memory connector, install one memory module (if the computer supports a single module), and restart the computer. Then move the module to another connector and restart the computer.
Memory is detected, but a memory configuration or compatibility error exists
Be sure that the memory modules are compatible with your computer. If necessary, replace the memory modules.
Check the computer message that appears on your monitor screen.
