    System Freezes within 1-2 hours of start


    My Dell Vostro 230 system is encountering a strange problem.
    It freezes withing 1-2 hours after I start it everyday.
    When it freezes the screen gone blank, only cursor shows.
    I have already ran Dell Diagnostics Test without any errors.
    Also checked Hdd with Seatools and Ram with memtest86 without any errors.
    Also formatted and re-installed Win 7 Pro 64bit with latest updates without any luck.
    The strange thing is that, after freeze I have to just hard reboot the system.
    After that system will work flawlessly whole day !

    Any help provided is valuable.

    Hi kalpsr, Welcome to Seven forums.

    Have you tried logging to Safe mode and checking? If the PC does freeze in safe mode then it possibly is an issue with drivers or software. Do you have multiple Anti viruses installed?

    Try to update the graphic card drivers to latest. Download the latest drivers and also download "Driver Sweeper". Uninstall the drivers and run driver sweeper to remove the left overs of the old drivers. Install the latest drivers for the card.

    Also, Run SFC /SCANNOW to check for errors on system files.

    Keep us posted.

    I am running only Quickheal, it's an admin console client 4.6. I tried to start system in safe mode also. It starts fine but it is not feasible to work in Safe Mode for 2-3 hours. Because it happens only 1 time daily after I start it. I also tried by changing the Graphics Card with an Nvidia 9500GT but problem remains same. Also ran Driver Sweeper and then installed fresh driver for 9500gt i.e. (332.21-desktop-win8-win7-winvista-64bit-english-whql). SFC also didn't find any problematic files. Please guide further.

    You got to run SFC SCAN atleast 3 times to get the results.

    Cleaning the contacts on the RAM and vid card with high purity alcohol fixed the same problem for my computer. However, your new vid card should not require cleaning.

    Yes also tried cleaning RAM with ISOPropyl. And Graphics Card is new and problem remains same with both Cards. So, I don't think its the culprit. Any more suggestions??
