Computer is freezing or not running well
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 installing 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.
Give your computer a bit of rest. If you leave your computer on all the time, you can often fix a problem by turning off the computer, then unplugging it (or remove the battery, if it is a laptop), then holding down the power button for 30 seconds while computer remains unplugged (this will often cause a light, or lights, to flash), then reinserting the battery, plugging the computer back in and powering it on. 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.
Diagnostics. Many computers now come with built-in diagnostics which can tell you if you have certain issues. Two brands of computer that normally have diagnostic options are HP/Compaq and Dell. To access these diagnostic options:
- Power down the computer, wait a few seconds then turn it back on.
- HP – Immediately start pressing F2 on startup to access the diagnostic menu. Select Start Up Test, Quick, One Pass (if option is present) to begin the testing process.
- Dell – Immediately start pressing F12 on startup to access the diagnostic menu. Use the arrow keys to select Diagnostics from the menu.
- Write down any error codes and consult the internet, the computer manufacturer or a local technician for assistance.
Open the cabinet of your computer and check the temperature of the metal chassis. If it’s hot, then there may be a heat related issue. For laptops, you generally do not want to try to open the case, but you can still vacuum the fan ports. Some computers just run hot, particularly laptops, but heat is never good for electronics. 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.
Tell tale signs of motherboard failure:
- You have switched on the computer being indicated by the lightand fan also starts to spin. But there is complete black- out on the computer screen with the hard drive not working within 10- 15 sec.
- The initial start up functions appear like indicative light, fan and hard drive sound, but disappears after a while i.e. 5 – 3 minutes.
- A high pitched sound comes from the laptop when you press the “on” button.
- Last one can be that even when you have switched on the computer nothing happens.
Cause of Mother Board Failure
There are numerous reasons why a laptop’s motherboard would fail. But some common and often unlooked corners include:
- Electric and voltage fluctuations
- Dust particles, smoke, laptops age
- Fan failure often causing over heating issues
- Crash or physical damage
Even the signs of motherboard failure mentioned above needs to be looked into, there are some exceptions to be looked when checking for laptop motherboard damage and they include:
- The black screen could be an indication of a possible back light problem. In-between the hinges there is a button which acts as an on/off switch for the laptop’s back light. This buttons automatically get switched off when the lid is closed. However, sometimes it gets stuck. Therefore first pull the laptop’s lid back and forth, if it is still the same then take a pin, find the switch and gently tap it. If even this doesn’t work, possible you need a laptop motherboard repair.
- If your laptops get switched on for a few seconds and then dies out, it could be due to battery being exhausted. First connected to the power outlet and then switch it on. Also check for connection cables, if it is still not works there could be two reasons. First your adapter might have been damaged, get it checked. If that’s not the case then the possible failure could indicate a laptop motherboard repair.
- Often re- setting the RAM and CMOS or updating the BIOS could save you from motherboard laptop repair.
As an advice – if you’re no expert in laptop hardware, but you know your motherboard has failed- Always go for a professional Motherboard Laptop Repair.
