Most likely your hard drive has failed.Or it could be the mother board.You can try to boot from a system disc,but don`t get your hopes up.Sorry,but someone is going to have to look at it.

Hi, Turn off the computer and open the side cover by removing two screws. If you have a video card remove it and clean the connectors with alcohol and also the memory card connectors. Re install it and install it back the side cover and turn the power that should work for you. Get back to us if this information helps you solve the problem. Good day...

My hp a 1410n desktop powers up but shuts down after five seconds

#1 on the list for this is shut down from over heat due to CPU fan not running or CPU overheat. Check to see if your CPU fan is turning on when your system is powering up. If its not.. thats your problem (get a new fan)... Even if it is it could mean the fan is not properly contacting the CPU with thermal paste. If this is the first time you\'ve powered the system up, your next step is to go out and get some thermal paste and put it under the CPU fan, if you\'ve been running the system and this problem just cropped up.. skip the thermal paste, its already there. #2 Next possibility is BIOs power settings are incompatible with your hardware. For example the frequency on the CPU is set higher then it can operate and its over heating. Some systems will automatically shut down and restart with default settings others you have to get into and set to default. can you get into BIOS? Can you reset your BIOS settings to defaults? Check your mother board manual. #3 A compenent is shorting out your system and needs to be replaced. Is the system posting prior to shutdown (beeping once on start up?) If its beeping more then once that means something else and you should read your manual. If its not beeping then its a short somewhere and you can bet you have a bad part in the system. To identify which part it is you can either disconnect things (RAM, Drives, vid card, PCI cards,ect) one at a time, attempting to start the system after each one or you can take everything but the bare bones out and try to start it. I usually take all the RAM out but one stick and start by testing them. Your RAM is the most likely place for a problem in this situation. #4 If you\'ve striped it down and it still can\'t get a boot (with no post beep). You need to replace the mother board.

Computer beeps

If you try to power on your computer and nothing happens but a bunch of beeps there is something you can do. The beeps actually mean something. To make sure you can hear the beeps check in the bios options. If there is an option for a silent boot you won't hear any beeps. If you hear one beep every time your computer starts then you don't have to worry about this.

If you want to check this setting refer to my other tip on how to enter bios and change boot settings.

If you try to boot your computer and nothing shows up on your monitor do these steps first.
1-Check all your cables in the back of the computer.
2-check your power source and power cord to the monitor
3-try another monitor if possible
4-If on a power bar try to turn off the power bar and reset the breaker

If you try to boot your computer and nothing happens and you hear beeps look at this website. The beeps you hear are actually telling you what is wrong. Look at the website by clocking on the link below and click on the computer beep codes link. If you want to scroll down past the link it will show you bios codes to enter the bios in your computer

Operating systems doesn't boot (BIOS beep codes)?

Do you have video going to your monitor? If not the beeps mean you have a bad memory stick in there. If you have video the beeps are the bios telling you that its not set right. More than likely you have it set to run too fast. Go into your bios find where the processor speed is located and choose a lower freq. rate. Its probably set too high for the memory you have.

On startup there is 4 beeps then 2 then nothing. The laptop belongs to my grandouther.the power coard was frade,so my guess is that's where the problem started.

Beep codes are used by the BIOS during the POST to report certain initial system errors.
If you're hearing beep codes after you turn your computer on, it typically means that the system has encountered some kind of problem before it was able to display any kind of error information on the monitor.
Follow the steps below to determine what system problem the beep code is representing.
Difficulty: Average Time Required: Anywhere from 10 minutes to a few hours depending on the cause of the beep code Here's How:
  1. Power on the computer or restart it if it's already on.
  2. Listen very carefully to the beep codes that sound when the computer begins to boot.
    Restart your computer if you need to hear the beeping again. You're not likely to make whatever problem you have worse by restarting a few times.
  3. Write down, in whatever way makes sense to you, how the beeps sound.
    Important: Pay close attention to the number of beeps, if the beeps are long or short and if the beeping repeats or not. There is a big difference between a "beep-beep-beep" beep code and a "beep-beep" beep code.
    This is all important information that will help determine what issue the beep codes are representing.
  4. What steps you take to solve a particular beep code will differ depending on the BIOS manufacturer.
    Choose the correct beep code troubleshooting guide below based on your motherboard's BIOS manufacturer:
    Tip: Not sure what brand of BIOS is on your motherboard? See this How to Determine Your Motherboard BIOS Manufacturer guide for some helpful advice.

Monitor (no signal) after replacing mother board and CPU

try only connect Monitor and keyboard, and check for booting (disconnect all the rest (HDD, CD DRIVE, Sound Card, Network Card, ....) then try connect one by one and always off to change hardware config.

If dont work with monitor and keyboard, try reset bios(jumper),check again, then replace memory modules (must be compatible to new motherboard), evan dont work, send back the motherboard for defective motherboard.

Emachine t3958/d845gvsr mobo

try resetting your bios.. reset it to system defaults.. check all connections properly.. pc to monitor..etc etc..
if you mean no error code by "no bios beeps" then it's okay..
if you mean even the regular single beep after post is not heard than chances are high that your video card has some problem.
