Does your Computer hang frequently? Fix it in two easy steps.

Problem: The mouse freezes and the screen seems to have come to halt and also keyboard does not respond as well.

This is generally a computer hang. Main reasons behind the PC hangs are:

Why Computer Hangs?

1 Overheating of processor / Motherboard. If the cooling fan is faulty, the processor gets heated up and ceases to work beyond a particular temperature.
2 Faulty hard disk drive.Hard disc problems also hangs the computers in case the important Operating System files needed to keep the computer running, become in-accessible.

Solutions : To Fix the PC hangs (computer hang problem),you need to follow two steps:

Step1: Check that the cooling fans on the processor is working properly or not. So ensure that the fan is working fine and is clean. If not, then get the fan replaced. Also check for the additional fans on your computer casing/cabinet(if any).

Step2: To Fix this, run a disk scan which checks for disc errors and fixes the bad sectors (some examples are scandisk and checkdisk utilities in windows). If there are bad sectors which can not be repaired, then you need to replace your hard disc.

Tip for enhanced performance: Once there are no bad sectors and the disc scan is complete, do a de-fragmentation of your hard disc partition(this may take long time), it will help the computer to access files easily and computer runs better(also fast in some cases).
These three steps will fix your computer hangs considerably.

    On re switching on, it boots alright & all desktop icons appear but clicking the mouse on any of the icons is non responsive & so I cannot operate my laptop for any purpose.

  17. i was disappointed after format my Pc coz it was still hang even i changed heatsink… im also changed RAM but it was still not working, I rmved my fan n processor bt gets hang.still..What can i do???…;(.. how to check motherboard if it bad sectors

  18. @Yarande
    – Check your temperature @ BIOS, U’ve change your RAM and heatsink (Cpu cooler) then it should be fine, your problem only lies on your hard disk or vid card.. check their temperature use SPEEDFAN, check your cables.. it’s either a faulty HDD / VIDCARD or it’s your MOBO . T_T .

  19. some reasons computer hangs, if your pc have a built in vga and you used it, the vga shares some capacity in the memory, most of it get the 64mb space, and the memory adjust the speed of bandwiths, the memory over clocking the speed and adjusting the page file, and resulting for a hang senario.

    before you open your pc reset youre cmos battery remove it from the slot then count for 10 seconds then put it back, these enables the default value of the dimm slot of the mother board to be prior readable then boot it up press f1 do not change the value of the bios just press f1 your computer will perform as its las good configuration

    avoiding computer hangs

    1. dont use a built in vga if youre trying to install a large amount of software, if your installing large amount of software add a video card compatible to the board.
    2. buy a mother board that has a cmos reset if youre computer hangs turn it off and press cmos reset then boot it up again press f1 to continue then youll see the result
    3. just always remember what board compatibility you have must be equal if your planning to add hardware. for example, if your board have a speed of a dimm memory slot of 400mhz
    buy a memory equivalent of a speed of 400mhz. some board allow over clock but the stability is not quite short.

  20. well from yesterday my PC started to hang while playing games like starcraft 2 and fallout 3. It actuallly started to hang after a few mins of gameplay but this isnt natural cuz i’hv been doing this for a long time and played the games maxed out with out any probs what so ever.

  21. I followed the two steps listed above with my two computers and only one of them responded positively, but the other one is still hanging – up on me.

  38. Disable any firewall and check if it resolve your problem, If resolve then uninstall firewall and install again. Second and most probably your system may hang due to SMPS, change your SMPS. Third Check your Hard disk for bad sector using seagate HDD utility. Fourth, Change the Data cable M/B to HDD
