  1. Hello,
    I bought a new computer couple months ago and now my pc is crashing almost every day. I did run the memtest+ and no errors.

    My pc's specs:
    AMD ATHLON 64 X2 7750 AM2+
    A-DATA DDR2 800 1GB (x2)
    Power: ANTEC PSU BASIQ POWER BP500U-EC 500W
    MotherBoard: ASROCK AM2+ AMD780G

    OS:
    Windows XP +SP3

    All five errors are 0x000000C5: DRIVER_CORRUPTED_EXPOOL and is defined as
    an attempt occurred to touch invalid memory at a process IRQL that is too high. This is almost always caused by drivers that have corrupted the system pool.

    All five pointed to the same driver as the cause of your crashes: vsdatant.exe; this belongs to Zone Alarm

    We have lost count of how many people have had issues with ZA and particularly this driver.

    You can do one of two things:

    1. Update ZA and check out their forums to see the "fixes."

    2. Completely uninstall ZA and try the free firewall version of Online Armor (brand new version just released) or the free COMODO. And if you need a free antivirus Avast 4.8 or Avira Antivir. And if you need a free antimalware/spyware then SUPERantiSpyware (needs to be updated manually daily).
