    Default Help! Processor at 100% coz of CSRSS.exe

    hi,

    my computer freez up after few houres it turned on and it gets REAL slow after couple of hourse it turned on.
    when its freez i saw that the process csrss.exe takes 100% of the cpu, i can move my mouse but if i click a few times the computer makes beep and locked up complitly for few minutes.
    when the computer get slow, the csrss.exe is at 20-40 % of the processor, and when i open 3-4 windows of Internet Explorer it get very slow too.

    i ran Ad-Aware, SpyBot S&D, Norton,
    i formatted my computer twice,
    i used every test and diag. i could think of, every thing seems to be allright.

    i use win XP Pro,
    Processor P-4 1.8 Ghz

    ever since this problem started i get once in awhile this error msg:

    The instruction at "0x086cf688" referenced at "0x086cf688". The memory could not be "read".

    click ok to terminate the program.
    click cancel to debug the program.

    i hope you can help me...
    10x
    Eitan.

    A bit of Google says that csrss.exe can also be hijacked by trojans/worms.

    Er, do you reapply service pack 1 and the hotfixes before you reconnect you to the internet (or at least have a firewall on) ?

    I was on a LAN that would infect you within seconds with a worm if you didn't have the hotfix/firewall installed.

    Check for memory problems with memtest86

    As Prescott pointed out, the problem wont be a worm, seeing as you have formatted twice.

    A RonTheRipper on this site and the same posting on 'umpteen' other help sites had a similar problem, but I couldn't find out if he found the answer.

    This site suggests looking at Power Options settings:

    If the problem is intermittent and happens "after a few hours" it might be a marginal memory timing problem. Running a memory tester for an hour might not find it. Try running it overnight (though timing is temperature dependent, and it's usually cooller at night ). Try slowing the memory down one step. If the problem never happens after that, suspect the memory.
