Re: computer powers off before loading

CoolDragon is right. If you have two RAM boards or more, you might even try booting with each one separately, until the computer works, then you'll know which one is bad. Also, you might first try removing and replacing them, it might just be a foreign object (dust, etc.) in a contct preventing the board from making full contact.

Re: computer powers off before loading

If it happens just after the memory test, it could be due to bad RAM chips. Try replacing them.

How do I fix: User Profile cannot be loaded?

What you describe sounds like a POST (Power-On Self-Test) error code beep sequence. The POST is the initial system test your computer performs when you first turn it on. The code you describe MAY indicate a RAM memory problem, but codes vary from manufacturer to manufacturer, so please check your documentation or check GOOGLE.

How to isolate issues between hardware and software

<p>It has been one of the dilemma of computer users is to identify what is really causing the failure in their computer. Often they think that they bought a defective product since they are getting these kind of errors in the computer. Having an error on your machine does not mean that the machine is defective or needs parts replacement. for all we know it might just need some simple troubleshooting steps to fix the issue. Here is a tip where you would be able to know if you need to bring your computer to a service shop for parts replacement or you can try to fix it at home by doing some troubleshooting steps that would help fix software failure in the computer system.<br /> <br /> On a Windows based operating system, you should always know when the issue happens. It will help much to observe your computer on how it boots up and what it does before you get to the desktop screen. Take a note on where and when exactly the error occurs.<br /> <br /><b> Power Failure:</b><br /> <br /> This is an issue where there are no lights on the power button of your computer, whether it is a portable system or a desktop computer. Obviously this is a hardware failure. surprisingly, discharging the flea power of your computer sometimes resolves these kinds of issues. Otherwise, you will definitely need to have a local technician look at your system for parts replacement.<br /> <br /><b> Note:</b> flea power is the charged power of our computer system. A computer system is made up of electronic components such as capacitors which hold electronic charges. To be able to discharge it, you should disconnect all power source from your computer and hold the power button for at least 5 seconds.<br /> <br /> <br /><b> POST Failure:</b><br /> <br /> POST is an abbreviation for Power On Self Test. as the name implies, it is the test that a system goes through to test the basic hardware components needed for a computer to boot. The components that it tests are as follows: Processor, BIOS (Motherboard), Memory, keyboard and video card. If there is a POST failure, the system would give you a black screen with lights on the front panel. Sometimes it will give you beeping sounds which would normally mean that you have a memory failure on your system. If you encounter such issue, you will need hardware technical support to guide you isolate further on what could be causing the failure.<br /> <br /><b> Boot Failure:</b><br /> <br /> Boot failure is when the computer is able to complete post. You will be able to know this if you hear a single beep on your computer. Isolating a boot failure from a post failure simply requires you to boot to the System Setup/configuration Screen (BIOS). If you are able to get to the BIOS, that means all the POST hardware component are good to go. However, booting to the BIOS differs per system. You just need to do trial and error on the following keys to tap as you turn your computer on.<br /> <br /> Del<br /> F1<br /> F2<br /> F10<br /> F9<br /> ESC<br /> <br /> To isolate an issue whether it is a software or a hardware issue, you just need to boot from the BIOS. If you are able to boot from the BIOS, chances are it is not a hardware failure and needs servicing.<br /> <br /> <p><img src="vincent_von_0.jpg" /><br /> <p><br /> If booting to the BIOS works, to further isolate the issue whether it is the advanced software, you need to boot to Safe mode. Safe mode is a troubleshooting state where only the basic applications and drivers are active. If you are having errors or boot failure, try to boot to Safe Mode. If you do not encounter the failure in Safe Mode, that means that there are advanced software being loaded in your operating system that fails. It is just a matter of knowing what that software is.<br /> <br /><b> Booting to Safe Mode:</b><br /> <br /> 1. turn computer on and tap on F8 before Windows starts.<br /> 2. You will be getting the Advanced Boot options. Use the arrow keys to get to the option for Safe Mode.<br /> <br /> <p><img src="vincent_von_0.png" /><br /> <p><br /> <p><br /><b> Safe Mode Definitions:</b><br /> <br /> Safe Mode: Just basic software are being loaded. Network drivers are not included which means no internet connection<br /> <br /> Safe Mode with Networking: Basic software and Network drivers are being loaded.<br /> <br /> note: for Vista or Windows 7, it includes wireless network drivers. This means that you can still connect to the internet with a wireless connection. In Windows XP, the wireless driver is not included even if you boot to Safe Mode with Networking<br /> <br /> Safe Mode with Command prompt: this is a troubleshooting state where you will be able to utilize DOS based commands.

Pc keeps turning on and off

There's a lot of reason why the computer keeps turning on and off. The following are the common factors -

1. Driver Issue - common symptom is BSOD (Blue Screen of Death) before shutdown. Get the error code that usually starts in 0x12345abc. Unplug any newly installed hardware or any usb device then check. If unsuccessful, boot to safe mode and if computer behaves normally then isolate the problem by performing a clean boot.

Start your computer in safe mode Microsoft Windows Help

2. Defective internal components such as motherboard, memory module, video card.
- Simplest way to check for motherboard issue is check the computer time. If it keeps on changing then probably a busted battery that needs to be replaced in the motherboard. If not, have it serviced by a local tech or reputable computer shop.

- Perform memory test that is built-in to the motherboard. If the memory is defective, either clean it using a pencil eraser or have it serviced.

- Listen for "beep sounds" before startup. This should give you an idea of what the problem is.
Computer POST and beep codes

3. Insufficient Power / Overheating.
- check the voltage of your power supply and if it is still sufficient enough to supply the motherboard. Check the temperature, if the fan speed is sufficient to cool down the processor. Download the software to check everything.

CPU CPUID System hardware benchmark monitoring reporting

4. Due to Viruses/Malwares
- perform the abort shutdown command to prevent the computer from turning off. go to start - run - type shutdown -i

5. If you are not comfortable doing all this, go to the nearest computer shop. Hope this helps.

Computer dead and beeping

If it beeps and not boot then it is the post routine telling you there is a problem. The post routine is run when you turn the power on to ensure the computer hardware is ok to run. The manufacturer of the bios routine can tell what is wrong by the type, number and duration of the beeps. Look up the code meanings and it will indicate the problem. If this sounds like nonsense to you then give the make and model of your machine and what the beeps sound like. ( beep beep beep delay beep beep beep) etc. and I'll look it up for you.

Desk top emachine powers on

You state that thre are no beeps coming from the PC upon boot. If you remove the memory entirely and reboot, you should get a series of BIOS post tones. If you do not get these, I would first test your power supply to make sure it is working properly. If it is, you most likely have a failed hardware component: either motherboard or processor. If you get no post tones without memory loaded and with a known good power supply, the motherboard will be your problem child.

If you DO get post tones with a known good power supply, try replacing memory 1 stick at a time (if you have more than 1). If 1 works, you have your culprit. If neither work, then you most likely have a bad processor.

Process of sometimes :-(
