why computer freeze

Computers may freeze on account of any hardware or software issue, so here you need to understand the exact reason behind it. Notice if the issue started when you connected any hardware peripherals like a printer or scanner; then it might be due to a driver conflict. If the issue occurred after assembling a new hard drive, then it might be due to insufficient power or too much heat. Follow the troubleshooting pattern below to repair your computer, if such problems occur.

    1
    Give your computer a bit of rest. If you leave your computer on all the time, you can often fix a problem by unplugging it, waiting at least 30 seconds, and plugging it back in. By cutting off the power to the motherboard, it allows the hardware to reset and the memory to clear.

    Determine if your computer becomes too hot. You will need to take a look inside for this. Remember that any time you need to open up your computer cabinet, shut down your computer and unplug it. If you have long hair, tie it back. Take off any jewelry that might get in the way. Also avoid wearing any clothing that produces a lot of static, as a spark can damage hardware and cause intermittent, hard-to-troubleshoot problems.

    Open the cabinet of your computer and check the temperature of the metal chassis. If it’s hot, then certainly there is some thermal problem. Gently examine the front and rear fans and blow out any dust. You can apply a clean cloth to dust out hidden particles. Remember: Your computer must be shut down while you're cleaning inside it.

        If you have more than one hard drive in your computer, avoid installing them right next to each other in the chassis; this makes them more prone to heat failure. To install an extra hard drive in a wide slot, such as the slot that holds your CD-ROM or DVD-ROM drive, you can buy mounting brackets at a store that sells computer parts.

        Even if your computer isn't having problems, it's a good idea to clean the fans regularly.

        Before you close up the case, check all the cables and make sure everything is still plugged in. If you have to reset a video card or a stick of memory, avoid applying heavy pressure to the motherboard as this can damage it.

    Inspect your Device Drivers. Many times when doing a Windows Update, your system may download and install an incorrect driver, which may result in the computer freezing. You can check the status of drivers from Device Manager. Unplug your USB device, if connected. Power-on your computer and see if it works. If it does, good; otherwise you can restore your computer to an earlier configuration. System Restore will roll your system back to an earlier set of drivers.

    Access System Restore at Start>Programs>Accessories>System Tools>System Restore to try and restore whatever settings you might have changed,

    6
    Inspect your Hard Disk.Your hard disk is a storehouse of information, so when it gets used for a long duration it might get cluttered and patchy; this slows down the performance of your computer. Hence, use your Windows utility CHKDSK to scan and remove bad sectors on regular basis. It is the best preventive way of maintaining computer health.

Blue Screen of Death

    1
    Understand the Blue Screen of Death. A more difficult time comes when your computer refuses to load any These gain access to your computer through loopholes in application software or in the operating system. To eliminate these programs and fix your computer, scan with a compatible anti-virus program.

        Registry Errors.The Windows Registry holds information regarding hardware and software settings on your computer. If a malicious program corrupts the Registry, it may result in a blue screen error. These problems could be fixed either manually, by editing the Registry directly, or with third-party software that can check and repair a corrupted Registry. Always back up the Registry before attempting to edit it.
