    I have a wierd problem that mostly occurs during downloading from the internet at high speeds only. for example, if im downloading something off mIRC at a rate of 100 or more kb/s, the chances of me getting this "Driver Irql not less or equal to blue screen of death" is higher. any suggestions are greatly appreciated

    It could be:

    1) Bad Memory, Insufficient Memory, Conflicting Memory :: Take out the memory, put the memory back in. Try the memory in a different slot. Try different memory.

    2) Insufficient Power :: Unfortunately there is no cheap way to try this, however you can borrow one from a friends pc, or a spare pc, minimum wattage required by most pc's is 250. Use a minimum of 300 watts if you try this step.

    3) Video Card is incompatable with the motherboard, or invalid settings and drivers :: Try a different Video card, use both a PCI and AGP (if possible) to see if your AGP slot may be bad.

    4) Network driver, IRQ, or card is bad / conflicting :: Reinstall the network card in a new PCI slot, Update the drivers, and disable sound. After the card has been reinstalled and is functioning reenable the sound card.

    5) Bad PCI Slot :: Switch the slot that the Sound card, network card and / or video card reside in.

    6) Sound Card conflicts with video card / driver :: Try an older video card, or disabling the sound (by removal or disabling in BIOS)

    7) Out of date BIOS (do not attempt if you do not know what this means) Flash with the newest version.

    You could try disabling Windows from dynamically assigning irq's(Interrupt Request) to devices, by adding the "/pcilock" option to the Boot.ini.

    If you are running XP depress Windows+Break keys. Select Advance tab, Settings (Sartup and Recovery) and Edit. Then add "/pcilock".

    i.e., Multi(0)disk(0)rdisk(0)partition(1)"Microsoft windows xp home edition" /pcilock
