    Does it freeze on you if you try doing it in safe mode?

    check if you do have a virus or nasty lurking around in there, as you said that it causes the freezing when you do a virus scan, and that is usualy a symptom of a few nasties that exists...

    Click here for instructions on how to completely check your system, then post a hjt in the security and web forum..

    Get a good antivirus such as Bit Defender and do a Scan and it will remove and viruses/spyware from your pc. If it doesnt install or freezes when scanning like before then go onto my computer and right click you r main hard drive > properties > tools > check now and it will fix any errors in your hard drive

    I have kaspersky antivirus but it seems it doesnt happend with only virus program but also some programs...

    When i turn on my pc and it starts off on POST i see

    Intel ® Pentium ® 4 CPU 3.60GHZ
    Speed: 3.60GHz

    But when my pc freezes and i restart that turns into

    Intel ® Pentium ® 4 CPU 3.60GHZ
    Speed: 3.75GHz

    Is it normal to do that?? to go above the 3.60GHz?

    Someone told me my pc is overclocking itself...i have never overclock my pc.
    Also someone else told me it could be a BIOS problem.
    Anyone could tell me their opinion?

    It could be that the button battery on the motherboard is starting to die?

    open the case up, and inspect your motherboard. While you're there you may as well see if there's any physical damage (burns, capacitor damage, unusual marks etc) on any of the components inside.

    You should see a small round battery 15mm in size. You can try taking that out and puting it back in after a minute (ie bios reset) and/or checking/replacing it if its dying (not enough current)

    you didn't mentioned if you could get into safe mode or not..

    yup i went into safe mode and ran antivirus once it was scanning the pc froze
    but what i dont get its what i posted

    When i turn on my pc and it starts off on POST i see

    Intel ® Pentium ® 4 CPU 3.60GHZ
    Speed: 3.60GHz

    But when my pc freezes and i restart that turns into

    Intel ® Pentium ® 4 CPU 3.60GHZ

    Its normal for the cpu clock speed to deviate a bit, eg mine is original at 3200MHz (3.2GHz) and goes between 3197MHz to 3201MHz (stock speed, no overclock) but a 150MHz bump like so could mean either your RAM timing's changed, FSB changed, inconsitant power or some bug in the motherboard electronics.

    Antivirus and other scanners usualy tax a lot of CPU power as well as alot of other resources out of the machine at one time. seeing that it still exist in safe mode (minimum programs active) then it could be either a stubborn nastie (rare) or a hardware problem. So my question is this: Does it happen during any other time like an intensive game or a movie etc?

    To rule out hardware, theres a few things i'd like you to do, and answer if you've done it and if it fixed anything.

    Download Everest Home (google for it). Install it and take a look at Computer>Sensor page, post all the info on the Temperatures and Voltages.
    Start a virus scan and then take another reading after a minute into it, or before you know the PC will freeze and post the info again.

    Download Memtest on a bootable CD or Floppy and run it for 10 passes or more with 1 stick of ram at a time, then alternate to the other stick if you have more than 1 running on your system. Note if you have any errors/fail or not.

    Go to Start>Run cmd type in chkdisk /f
    if it tells you that it needs to be run after you reboot your PC say 'Yes' and reboot. Let it fix any errors.

    If there's no errors on memtest and chkdisk has fixed all the other errors, and you're still stuck with the virus scanner, then follow what i've told you to do in my previous post (inspecting the motherboard, reseting the BIOS etc) and tell me the results of it.

    two things that caught my eye that you realy need to check on is the CPU temps being ridiculously high and a very strange voltage reading..

    CPU:
    Open the PC up, get a vacuum cleaner or a can of compressed air and give the insides a good dusting, paying special attention to the Heatsink (silver block of aluminium with fins on it). Clean up the fans as well and ensure they are functioning properly. *Optional* tie up any loose cables to the sides/edges of the case..

    PSU:
    With the PC still open, look for the PSU (grey or black box that all the power cables come to/from etc) and on one of its sides should be a sticker. Post everything you see on that sticker (make/model, voltage/amps rating etc). *Optional* Google how to test your PSU, and note what voltages and amps is comming up in the +12V line...
