    Most likely hardware failure. Which? You have to test. RAM, HDD in the first place.

    Firstly I would take out the RAM Modules and use an soft Pencil Rubber for to 'clean' the connector feets of those modules. Also use Alcohol and an old toothbrush for to clean the connectors in the RAM Modul Sockets! Test the work of the computer again!

    Not forget to blow out all dust from the computer's inside!!

    If memtest didn't find anything then it shouldn't be necessary to clean your RAM sticks. (But it couldn't hurt.)

    You said that you have already reinstalled Windows 7 and you are still getting errors?

    After checking the RAM, it's time to check the HDD.
    You have some options here;

    1. Use the Windows Error-Checking (Right click on your C:\ drive -> Properties -> Tools -> Error-checking),
    2. or you can download a utility from the hard drive manufacturers website,
    3. or you can use a 3rd party free program you can find online.

    There are mainly those 3 candidates (own experiences).

    1. HDD
    2. RAM
    2.1 PSU

    Also some times heating issues due to dirty vans. Be careful when using a vacuum cleaner and vans which are still plugged in!!! The undertow makes them rotating and as you know they induce a electric current on the board...

    I'd stress test the HDD..I assume you'll encounter R/W errors......above all I'd backup data NOW!!! Better safe than sorry...

    Depending on the age, I would add bad motherboard capacitors to the list. Visually check for bulging or leaking.

    Jep @Captain :)

    To open case and have a look is actually the first thing I do...looking for dust, loose plugs, cards. :) Also sounds..some HDDs get noisy/sound like hanging before they die...
    Never had issues with capacitors onboard, though. Used quality brands always....capacitors at PSU yes....especially at cheap ones...one even emitted smoke while stress testing memory lol.

    One of my pc's was freezing randomly 8 months ago, it had then 4 years old. Opened the case and found the 3 filter caps around the CPU a bit swelled. Changed them for a new ones with even more capacity (a bit larger than original ones) afterwards problem solved. :cool:

    I've seem random freezing and blue screens due to bad caps around the memory slots or cpu.

    I even had an HP lcd monitor fail because of bad caps - easily and cheaply fixed with a soldering iron, after some googling to find the diagnosis.

    thank u guys 4 replying
    first Mr. X bro I had used memtest v6.1 and found no errors and also my Ram is new
    second I had replaced the capacitors in PSU a few months ago
    third I had checked my hdd for errors, some errors have been found and fixed and my PC started working properly
    but after few days it is again freezing then I again checked for errors and fixed them and PC started working properly
    but now it is still freezing randomly I have 2.97 gb free in D drive, 4.58 gb free in E and 5.96 gb free in F
    And also it mostly lags in summer time of high temperatures
    what to do now?

    performed an extended test on my WD 500gb HDD
    Spend 1 hour and 30 minutes on the test, test results shows there are bad sectors on your hard disk
    and when I clicked repair errors it shows "unable to repair errors"
    what to do now guys, I am sure the freezing problem is bcoz of HDD
    Plz provide an efficient solution
