Two long beeps is the code for memory trouble. Try removing the memory modules from their sockets. Make sure the sockets are free of dust (computers can get pretty dirty inside), using compressed air (available canned from office supply places, Wal-Mart, etc.) to blow them out if needed. Make sure the contacts on the modules are clean. You can use a pencil eraser with light pressure to clean them off. Reseat the modules firmly in their sockets. Then try restarting the computer.

If the trouble continues and you have more than one memory module in the system, try replacing them one at a time and restarting the computer to try to determine which one is causing the trouble.

If the trouble still won't go away, see if you can borrow a known good memory module from someone and try that. You might have a failed system board or multiple bad memory modules. (It can happen, and can drive you nuts when you try the "one-at-a-time" trick. I've been there!)

Hope this helps!

Monitor stays in sleep mode?


when you disconnect the monitor from the PC do you see the self test appear on the screen? if you do then the monitor is working fine.
the issue is most likely that the computer's screen resolution is too high and your monitor cannot output that resolution , so it stays a blank screen or in 'sleep' mode as you described.
youd need to go into either Safe Mode when booting the system or find another monitor preferably a newer model to connect your computer to and decrease the resolution before connecting your monitor.

I have a Sony Vaio VGC-LS25E All-in-one PC. When I power it on, nothing happens, the display is blank and there are no normal boot up sounds. Yesterday, it beeped 3-4 times when turned on, but it is not...


Amazing. I have the same computer and the same thing just happened to me. The computer works and if I press the sleep button I can see the screen for about 4 seconds.

My computer turns on but my monitor screen stays blank my key board lights dont come onim wondering if this is my harddrive because it doesnt make any noise when i turn it on


Hi,
Its highly unlikely that its the hard drive as a computer will still show a post or splash screen without a hard drive being installed.
Is the computer making any beeping sounds?

Power on emachine T6420 and moniter is blank. The moniter soon loses contact with the computer. The fan run and power is OK there is no beep code.


If you mean after the computer performs the self test the screen goes blank and stays blank, eventually turning off you are having a hard drive problem. When the computer boots you should see an E-Machines logo and/or a self test on the screen. That is done by the motherboard as part of every boot up. After that the motherboard passes control to your boot device and loads your operating system. If your computer stops booting at that point, your boot device is not working properly. That could be caused by many things - virus, hardware failure, power outage. If you really mean you see nothing at all on the screen when you press the power button your computer simply is not working at all. Open the case, blow all the dust out of it and reseat all components you can, then try again.
