Hi clark_styx,

Yours is not an uncommon problem. Let's get to it:
-First, did you change any thing i.e bios upgrade? If so, we'll get you to available BIOS codes.
-Next, does your cpu seem to be slowing down? If, so, it could be a heating/cooling issue i.e. cooling fan failure. Take off the case and clean out the dust bunnies.
-BIOS failure at power on? Usually means your BIOS is corrupted. BIOS upgrade reccommended.
Your cpu runs whats called a POST- (power on self test) a diagnostic utility, if your BIOS is failed or failing you will either see BIOS failure codes or hear a series of beep codes. Check these areas and if your still having BIOS issues hit me back, we'll get you going of die trying, lol.

Thanks for using

Sincerly, cyyyd7

To your query, "...signs of a BIOS failure...", a few I have come across on desktops:

  • "Boot Block" message;
  • twee-dee beep (often with Asus);
  • continuous beep (not sequenced);
  • will not retain day/date/time even with new battery;
  • parts of CMOS/BIOS setup/config defaulting;
  • no boot.
Hope that 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.

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.

Msi u100 018us notebook says boot failure-press any key to continue---------and PXE-E61 media test failure check cable-------and PXE-MOF exiting PXE ROM wont let me boot computer can it be the hard drive...

It definetly can be the hard drive and most likely is. If you know how to get into BIOS then I would suggest going in there and seeing if BIOS can detect your HDD. If it cant then it definetly is your HDD. If it is detecting it then you might have a bad sector on the HDD that is corrupting the boot sequence for your operating software.

If BIOS is reading it I would suggest putting in your recovery CD or a fresh install of your operating system and see if it can reinstall to that HDD.

All BIOS system are different so I could not tell you without knowing what BIOS your running how to enter it. You should be able to hit escape for F10 while computer first is starting up to enter BIOS settings if you didnt know how to already. Write back if you have any more questions please or need further instructions or clearification on what ive said.

My 7Y250MO hard drive starts clicking and after a few seconds the system locks up only fixed by powering down and restarting.

Try doing the self-test for the hard drive. It could be a sign of hard drive failure. Just boot to BIOS go under diagnostics then select Primary Hard-drive Self Test. In hp notebooks, we use f10 after turning it on to boot into bios. Ask your computer manufacturer how to boot to BIOS. If you're Hard drive passed the test you might want to try re-installing the operating system. It could be a sign of Windows crashing. If you're Hard drive failed. There you go. You have to replace the hard drive. Hope this helps.

Blue screen. 0x0000008e (0xc0000005,0x80409A88,0xf789e360,0x00000000.

This error occurs due to the following reasons: Faulty RAM, registry errors, incompatible drivers, hardware failures, faulty BIOS configuration, Viruses.
Follow the steps below to avoid the BSOD error message occurs again.
Check whether the RAM installed in your computer complies with the motherboard specs. Replace the RAM if needed. You can also check the systems with a friend's RAM to know whether the error message is due to RAM.
Use a free registry cleaner/fixer software available to clean/repair your windows registry. (Ccleaner is good at this)
Do not install incompatible device drivers. Install only Microsoft Signed drivers. Update your existing driver software from the corresponding device manufacturer's website.
If you have installed/changed new hardware, check whether it is supported by your system. Also check whether it is installed properly. If needed test the systems without the faulty hardware. Check whether you've installed correct/signed driver software for that particular hardware.
If you have reconfigured your system BIOS, set it to default/optimal/recommended settings and test the system. Disable features like BIOS caching.
Use an original and up to date antivirus system like Norton, McAfee or Kaspersky and run a full systems scan.
Keep your windows updated with current patches and fixes to protect the systems from unwanted troubles.
All the best.
