My optiplex 320 is making two high pitched beeps on starting boot, also im not getting anything on the monitor


James,
It sounds like the refresh rate is set to high. Since you do not mention what OS is installed I have listed information on how to change in Windows,XP.
Start the computer and press the F8 key. Choose Safe Mode. Once the system gets into Windows follow the steps below and then restart the computer. If this does not resolve your issue email me at my email address below and include your OS information.

How to Change the Screen Refresh Rate of Your Monitor

  1. Click Start, click Control Panel, click Appearance and Themes, and then click Display.

    Alternatively, right-click the desktop, and then click Properties.
  2. Click the Settings tab, and then click Advanced.
  3. Click the Monitor tab, and then click the screen refresh rate that you want to use.
NOTE:
  • The default refresh rate setting is 60 Hertz (HZ); however, your monitor may support a higher setting. Check your manufacturer's documentation for information about the settings that your monitor supports.
  • If you use a higher refresh rate, you can reduce the rate that your screen flickers; however, if you specify a refresh rate that is too high for your monitor, your screen may become unusable and your hardware may be damaged.
  • Changes to the refresh rate affect all users that log on to the computer.
Or your system is giving off a beep code in which case the beeps come in a 3 beep sequence. Below is the beep codes and what each represents.Beep Codes

My Dell Inspirion Mini 10 is beeping 8 times when I turn it on. Nothing on the screen.


Try holding Fn + End with battery and power cord out and while still pressing Fn + End plug only power cable back in and try to power on.

ON POWER UP SPLASH SCREEN DISPLAYS THEN FREEZES


I see failure in booting. I'm afraid your HDD has problem, have check with JVC Service Center near you, chances are high of HDD failure like you have that can be repair.

E125 screen failure symptoms


As a rule the failure of the LCD on a Casio pertains to greying out of the top 1/3 portion of the screen. The touch screen - the part that senses your stylus inputs i.e. taps, double taps, tap & hold / drag continue to work. Seems like the failure is not in the LCD but the fluorescent lamp at the top end of it. It could be the lamp itself or the inverter circuit. Have an experienced technician check the lamp out. It is not a very diffucult item to replace. Nor is there any desoldering / soldering involved.
