XPS poor performance.

My Inspiron XPS (3.4 GHZ, 2 GB Ram) is running very slowly. I have ran QuickTechPro's Benchmark test on the CPU and am getting 64K Dhrystones & 50K Whetstones. According to it's charts, it's running about par for a Pentium 1 150mhz. I ran something called CPUMark2 on it, it ground to a halt on the floating point test (I gave up after a couple of hours with no results). My other laptop (Dell Pentium M 1.6ghz) ran circles around it on all the tests. I was reencoding some MPEG2 files, once again the 1.6GHZ ran circles around the 3.4GHZ, after 8 hours, I had to stop it and beat my head against the wall. I've reinstalled windows and ran tests outside of windows.  Has anyone else seen this?

    The most likely reason for your poor performance is that your CPU is overheating and its speed is being throttled in order to keep the CPU as cool as possible.

    I suggest that you buy a can of compressed air and liberally blow out your vents in order to remove as much accumulated dust and debris from your CPU heatsink.

    Additionally, I suggest you also doublecheck that your hard drive has slipped into PIO mode.

    I'll try that... It has always been quite warm, I try to keep the vents clean and open. Is there anywhere to check the system temperatures? I didn't see anything in the BIOS.

    I did update the BIOS, it helped some... I noticed that while running a benchmark, if I hit the fn-z it'll perform a lot better... maybe it is heat related.

    You need to try a few things,
    Number one beeing to download a new bios, since they have fan-controlling on them.

    Number two is to download and install the speed-step for your CPU.

    Number three is press [FN]+Z to reset the fan controllers so that they function.

    And you cant check the heat on the dell computers, sure a 3:d part software might show you a number, but it dont show the correct one. only way is to take a temperature meter and stick it to the CPU.

    Try running your computer as hot as possible, if it shutsdown and you cant start it for 15-30 minutes, you have had your first thermal shutdown, and then you should call tech support, they will probably get you a new fan+heatsink

    The heat sinks can become  totally blocked by dust. The  two fans on the bottom are easily removable.  Remove the fans and see how much dust are on the heat sinks.
