Computer can't boost up

I brought a new motherboard and cpu, after fixing on the computer the system can't boot up. I had checked all my hardware including power supply(450w), Ram(DDR II, 512MB), Hard Disk (80G Sata drive), and CD Rom all are in working condition. The ATX casing power supply, reset button, hard disk led, power led are properly insert in the motherboard and also the usb plug. The motherboard had the green light appear on it, but the system still can't boot it. I wonder if the brand new motherboard and cpu I brought is faultly before I fix into my ATX casing?

There are a host of things that could cause this. The first thing to check is to mak sure you have the proper memory setup for your motherboard. Often these days you need to install memory in pairs for the board to boot. Refer to your motherboard manual and make sure the memory you have installed is right fro your board and that you have it installed in the right slots. If you do and it still doesn't work, please reply with your motherboard, CPU and memory specifications so I can look into this further.

Inspiron m5030 cpu fan start working but stop working in a few seconds


Step 1:
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Remove new hardware If any new HARDWARE has been recently added to the computer, remove that hardware to make sure it is not the cause of your issue. If after removing the new hardware your computer works it's likely the computer is either not compatible with the new hardware or a system setting needs to be changed to work with the new hardware device. Remove any disks or USB devices Remove any disks, CD's, DVD's that are in the computer and if any USB devices (Ipods, drives, phones, etc) are connected disconnect all of them as well. Reboot the computer and see if anything changes. Disconnect external devices. Remove everything from the back of the computer except the power cable. Turn on the computer and see if it beeps normally. If the computer has never beeped keep the monitor or display connected to see if any change occurs. Check all fans Make sure all fans are running in the computer. If a fan has failed (especially the heat sink fan for theCPU) your computer could be overheating or detecting the fan failure causing the computer not to boot. Check all cables Verify that all the cables are properly connected at that there are no loose cables by firmly pressing in each cable. All disk drives should have a data cable and power cable connected to them. Your power supply should have at least one cable going to the motherboard. Many motherboards may also have additional cables connected to them to supply power to the fans. Disconnect all expansion cards If the above recommendations still have not resolved the irregular POST, disconnect the riser board (if applicable) and each of theexpansion cards. If this resolves the issue or allows the computer to POST connect one card at a time until you determine what card is causing the issue. Disconnect all drives If you were unable to determine by the beep code what is failing or do not have a beep code disconnect theIDE, SATA ,SCSI or other data cables from the CD-ROM ,Hard Drive and Floppy Drive from the Motherboard. If this resolves your irregular POST or generates error messages re-connect each device until you determine what device or cable is causing the issue. In some situations it can also be a loose cable connection that causes the issue. Remove the RAM If you continue to to receive the same problem with all the above hardware removed, disconnect the RAM from the Motherboard and turn on the computer. If the computer has a different beep code or if your computer was not beeping and is now beeping turn off your computer and try the below suggestions. Making sure to turn off the computer each time you're adding and removing the memory and then turning the computer back on to see if the suggestion resolves the issue. Re-insert the memory into the same slot. If you have more than one stick of memory remove all but one stick of memory, try rotating through each stick. Try one stick of memory in each slot. If you're able to get the computer to boot with one or more of the sticks of memory it's likely you're dealing with some bad memory. Try to identify what stick of memory is bad and replace it. If you're able to get memory to work in one slot but not another slot. You're motherboard is defective you can either workaround the issue by running the memory in a different slot or replace the motherboard. Power cycle the computer In some situations a computer may have power related issues often caused by either the power supply or the motherboard. To help determine if this is the cause of your issue try turning the computer on, off, and back on as fast as possible, making sure the computer power light goes on and off each time. In some situations you may be able to temporarily get the computer to boot. This should only be used as a temporary workaround if you're able to get this to work. Often this is good for users who may have not done a backup and need to get the computer up one more time to copy files before starting to replace hardware. Disconnect and reconnect the CPU For users who are more comfortable working with the inside of their computer or who have built their computer one last recommendation before assuming hardware is bad is to reseat the CPU by removing it and putting it back into the computer. Bad motherboard, CPU, RAM, or power supply If after doing all of the above recommendations you continue to have the same issue unfortunately it is likely that you have badMotherboard, PSU, CPU, orRAM. The next step would be either to replace these components or have the computer serviced. If you plan on doing the repairs yourself or you are a repair shop it is suggested that you replace the Motherboard first, RAM, CPU, and then power supply in that order or try swappable parts from other computers.

Tip

MAKING YOUR COMPUTER OPERATE VERY FAST & SECURED THROUGH CPU OVERCLOCKING


NOTE: OVERCLOCKING COMPUTER CPU MAKES IT PERFORM FASTER ABOVE THE FACTORY SET LEVEL, BEFORE OVERCLOCKING, READ THE GUIDE BELOW, AND VIEW THE SOFTWARE APPROACH HERE OPEN

drbrightirem.jpgOverclocking a processor means enabling it to operate above the manufacturer's specified frequency. Many internet sites provide instructions for overclocking. Processor manufacturers and many computer experts believe the slight gain in performance (only perceivable on CPU-intensive software) isn't worth the expense or considerable risk.

  • Get whatever tools you need: screwdriver, needle-nose pliers, motherboard manual, cooling hardware, etc.
  • 2 Find out whether your motherboard can be adjusted in the BIOS setup, with jumpers or not at all.
  • 3 Find out clock-speed limitations of the motherboard.
  • 4 Run all Windows and any third-party diagnostic applications you have. Fix all system problems.
  • 5 Make a complete backup of your system, documents and applications you don't have on CD-ROM. Do not overwrite these copies.
  • 6 If you have a BIOS-adjustable motherboard, make changes according to your motherboard manual, and skip to Step 15.
  • 7 Shut down computer.
  • 8 Leave computer plugged in to surge suppressor.
  • 9 Disconnect all peripherals from computer.
  • 10 Remove cover of chassis.
  • 11 Ground yourself to computer with any professional grounding equipment you have. Otherwise, ground yourself by touching a metal part of the chassis.
  • 12 If your motherboard has adjustable jumpers, locate the jumpers that control the CPU speed.
  • 13 Use needle-nose pliers to change jumper settings. Move jumpers to positions indicated in your motherboard manual for the clock speed you want. Check the internet for recommendations.
  • 14 Install a CPU heat sink, heat-sink compound, and a specialty cooling fan, if appropriate and possible.
  • 15 Put system back together, and reboot.
  • 16 If computer does not boot, and CPU still works, try lowering the clock speed. If that doesn't work, restore the original configuration.
  • 17 Check all functions, and run a CPU-intensive program.


  • NOTE: OVERCLOCKING COMPUTER CPU MAKES IT PERFORM FASTER ABOVE THE FACTORY SET LEVEL, BEFORE OVERCLOCKING, READ THE GUIDE BELOW, AND VIEW THE SOFTWARE APPROACH HERE OPEN Tips & Warnings
    • CPUs have rated and maximum speeds. Exceeding the maximum speed is far more likely to cause problems than more conservative adjustments.

    • Overclocking an Intel processor explicitly voids its warranty. Other manufacturers have similar exclusions. Intel prevents overclocking of some CPUs by disabling higher multiplier settings.

    • Expect a shorter life for an overclocked processor, including the possibility of its immediate failure.

    • Prepare to deal with seemingly unrelated problems that can be caused by overclocking: destruction of other internal components, lost data, system and application crashes, and an inability to boot the system. Such problems can occur randomly or materialize well after you have altered your motherboard

    Hello,

    you need a new CPU cooler and the part you will be needing is called 'CPU COOLER". Go to any computer accessories shop/store within your vicinity and purchase another CPU cooler. You will need to remove the one from your motherboard and use it as a sample to get another one so that you can get exact size of cooler that will fit your CPU because CPU coolers varies in size and shape.

    Good luck.

    Abit NF8 wont even post. I get beeps of 4 short repeating beeps, space, then repeat till I power down. DVD burner lights up, but not floppy, or hd


    4 beeps means that a main timer on the motherboard is not working - board replacement time, as it is internal to one of the main chips on board.

    I have a K7VZA motherboard when i turn power on


    The very first thing you need to do is unplug all drives inc power.
    Now remove as many add in cards as you can without compromising the system.

    Try to boot at that point.
    If it boots re-connect each piece of hardware one at a time until you find one that causes a problem.
    Double check that item for any issues and replaces if needed.

    If you have had the fan off the cpu for any reason then you should have cleaned both the cooler fan underside and the top of the CPU and put fresh thermal grease made for that purpose on there. DO NOT use too much as that is almost as bad as too little.

    Is the fan the correct type eg motherboard takes 3 pin and fan is 4 pin ?

    Make sure it is connected to the CPU FAN pins on the board and not system fan.

    If you have another computer and the fan can be removed from the cooler itself you could plug it into the system fan port of another computer to try it out.

    under no circumstances should you run a system without the CPU cooler running as it could cause irreparable damage to the CPU

    My Screen is blank and fan continuously runs.


    your computer is not posting that is why you do not hear a beep. This can happen for 1 of 10000000 reasons but I would start with checking the RAM then all the other hardware to find a loose connection/dead hardware.

    Boot up problem: No Bios reading


    Try to unplug unnecessary hardware.. just plug in the monitor to video card, power, and the memory.. unplug the IDE cable or SATA and also the USB devices... Observe if your system will boot. sometimes hardware damages prevent your system to boot..

    1 Long beep every 2 seconds


    This particular symptom may reflect a problem with any number of components. A bad CPU or video card, for instance, may prevent the computer from booting properly. Often the number of beeps will clue you in to the offending hardware. Check your system or your motherboard manuals' troubleshooting sections for a list of beep codes.

    If the beep codes indicate a memory problem, make sure all memory is properly seated and secure. If you've recently added new memory, make sure it's compatible with your system. You may also want to try cleaning the pins on each module and each socket on the motherboard.

    If you have multiple memory modules, try to isolate any bad modules by removing all but one module and booting the system. If the system boots, turn it off, replace the module with another and boot the system again. When the computer refuses to boot, you've found your problem module.

    Again, you may want to reorder your memory modules. Faster modules in the DIMM0 slot can cause a problem on some systems.
