    The computer will not boot up. There is a consistent beep as soon you turn the PC on. Windows, the monitor, nothing comes on. I have unplugged everything and plugged it back in, but nothing. Ideas?

The power supply unit is bad. You will have to replace it. Also, it is custom specific ~ write down the specs of the PSU and order it from legendsmicro.com. This recently happened to me.

If it is beeping:
a) 1 long beep and 3 short beeps it is the graphics card. It might have been moved when replugging the monitor cord. Just remove the card and put it back in place. Stupid trick, but usually works;
b) 3 long beeps it is a RAM problem. Sometimes the same trick of removing and replacing works, but if not, it might be a faulty memory module.
Keep in mind (if you are a newbie) to unplug the power cord and to touch the metal casing prior to handling the graphics card or the memory modules! Do not get yourself electrocuted or destroy the components by discharging static electricity on them!

I'm having an aspire m5640. it does not boot. beep?


Yes if there are error on the system you should most likely hear a beep most of the time when there is no beep it is due to bad ram. Some times beep codes can't detect bad ram and your computer will not boot.
Open the computer up and see how many ram chips you have if you have more than one take the one in dimm slot 2 out. There should be small writing next to the slots 1,2,3,4 or Dim 1 dim 2 ect ect. you always want to keep slot 1 with ram so start by pulling out the ram out of slot 2 and turn your computer on. If your computer still dosn't post pull the ram out of slot 1 out and insert the ram that was in slot 2 into slot 1 if still no luck it's most likely your board but the best way to test this is to know that you have a good working stick of ram you could purchase one and if it dosnt work bring it back ... theres also the chance of your video card being bad but there is usualy a post code for it (beep code)
if you have no clue on what ram looks or how to open your computer just google for installing ram on a computer and you should find step by step guides

Compaq Presario stuck in sleep mode


Connect the monitor to some other computer, e.g., a notebook, and see if it does the same thing. If it does, then the monitor is the problem.
If it does not, then your computer is not putting-out any "video" signal, and so the monitor goes to "sleep".

If you have MORE than one VGA-output port on your computer, connect your monitor to the "other" VGA port.

Or, press-and-hold the ON/OFF button on your computer, to force it to completely shutdown.

Monitor keep going into "sleep" mode


Check the power setting in control panel of windows. If you have a monitor from another computer swap them and see if the problem stays with the computer or monitor.

My monitor goes to sleep mode at startup & can't access safe mode


Turn the computer off, open the case and remove the RAM. Does the computer beep when you turn it on with no RAM? If not, your motherboard is dead.

If your computer beeps, turn it off again and try putting one stick of RAM in. If the computer doesn't turn on normally, try the other stick of RAM.

Also, try taking out the video card and putting it back in.

Good luck,
Jason

Try to start my computer but tower keeps on beeping and monitor keeps saying going to sleep. What could be the problem?


Hi,

Probable reason for the beeping sound are:
  • defective, dirty or faulty seated memory sticks; clean, re-seat or replace (most likely);
  • defective, dirty or faulty seated video card; clean, re-seat or replace (likely);
  • corrupted BIOS; flash or replace motherboard (least likely).
The monitor going into sleep mode is because it does not sense any usable video signal from the computer.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
