    You do not need USB drivers. They are part of the OS. You have a hardware or software problem elsewhere on the computer... perhaps a software failure or conflict.. Are there any flags in your device manager.
    I seriously doubt you have a hardware issue with USB ports... if so, it is perhaps a motherboard problem.

    no everything looks good in device manager.. also if this helps, that blue screen pops up when i shut the computer down too. it will save the settings and say windows is shuting down then the blue screen pops up

    IRQ errors are always difficult to track down, because it can mean almost anything in actual use... We find that stripping down the computer to hard drive and one memory module to test, then changing memory module to test again... you have to test and examine every hardware component sometimes... it takes forever... In our experience with thousands of computers, it is usually video card or video driver, other PCI device such as ethernet card or modem (even if not used) or memory issue... but cpu fans and other devices wearing out can enter into the mix.
