    This problem has been steadily growing worse over the last few months.

    At times that appear quite random, the PC will seem very, very slow, or even to freeze. If I have Process Explorer or Task Manager running they show one process is using up to 99% CPU. I have found that if I end or kill that process, another will immediately take up the 99% CPU role. Eventually explorer.exe will be the 99% CPU user, at which point the only way forwards is to Power Off.

    Currently, the PC can even freeze after Power On and Log On alone.

    Hardware: Dell Inspiron 8600 laptop, 1.5GB RAM, 1.5GHz Pentium M CP
    Software: Windows XP Pro SP3, NOD32 antivirus, Comodo firewall

    If I canít fix this, Iíll go to Windows 7!

    How old is that laptop & how full is the hard drive? It sounds as if something in there is beginning to reach the end of its useful life. HTH

    A reinstall might be tried or maybe use the wubi installer with Ubuntu, which installs Ubuntu within a file structure in XP, so no repartitioning or othere special considerations are needed for the most part.

    If Ubuntu will run without triggering any of the problems then you can be pretty sure its a software problem that has developed with XP and a repair install might help.

    The first option will let you know right away if its software or hardware but of course its more drastic.

    Are you able to run a full antimalware scan?

    Can you boot into safe mode? Is there a slow down in safe mode?

    Do you typically see the same process using the CPU when the problem starts? What are the processes?

    Have you done any rootkit scans?

    Is the PC on a local network? Work or home?

    The laptop may just be showing age, but it could have another issue. Run Task Manager, select show processes from all users and post a screenshot and one of us might spot something amiss. Otherwise, if the Dell diagnostic partition is installled, hit F12 as it boots up and run that to see if there is a hardware problem.

    I agree with age. Also, in looking at the specs for the PC, it is just above minimum for Win 7. Changing to Win 7 will probably be a disappointment on this PC, and if your problem is indeed a hardware age issue, it may not even be compatible with win 7 and even if it is, if the PC fails, you will still have to upgrade to a new PC that will probably already have Win 7 installed. Definitely run the Windows 7 upgrade advisor. I would hate to see you spend the money on Win 7 and then have to upgrade your PC shortly thereafter.

    If your looking to keep your current laptop, i'd seriously start by going through all your installed apps and deciding what to dump.
    "1.5GB RAM, 1.5GHz Pentium M CP" ...this is some pretty weak hardware in todays computing environment, may not entirely stand up...anymore.
    Sure, you could instal windows 7, but it would not make for a very good experience ...and thats putting it mildly.

    You could always change out the processor and upgrade the RAM, but that might prove to be alittle more ambitious than your laptop is worth.
