    I'm working on a dell studio laptop.
    The original symptom was 30 minute+ boot up and it would eventually start Vista (Home Premium 32-bit).
    Malwarebytes came up with a few minor tracking cookies, removed them. Anti-virus came up clean.
    Reboot still takes over 30 minutes.
    Installed SP2 (took over 5 hours). Reboots.
    Now stuck in reboot loop.
    I ran dell diagnostics and everything passed, and I mean everything. I ran SATA long test, full memory test, everything passed.
    Now we move into the mystery.
    UBCD4Win hangs with a black screen (Waited over 1 hour)
    XP based ERD hangs with a black screen (Waited over 1 hour)
    Vista based ERD starts after a decent 20 minute wait. Backed everything up.
    Reinstalled Vista from DVD.
    Still slow boot. Driver installs taking hours.

    Any idea what's going on? Any help greatly appreciated.

    You're getting that slow of a boot after just reinstalling the OS?

    Sounds like a hardware issue to me.

    What are the specs on the machine?

    Dell Studio Laptop 1737
    Dual Core 2 Ghz
    4 GB of RAM

    According to the diagnostics there are no hardware problems. It's unclear what would cause it. Are BIOS viruses still surfacing?

    Definitely should not be moving that slow with hardware like that in there.

    Honestly, I have no idea what the issue could be. Sorry. :(

    Another strange behavior is moments of clarity- I'll be able to navigate folders and open control panel as normal, then I'll go to install something and it takes 10x the normal install time and often longer

    Try booting into Safe Mode and see if it responds faster. If it does I would suspect a driver problem.

    Safe mode performs no differently, it's a fresh install

    At this point I'm desperate for any suggestions.

    This is incredibly weird...I again, have no idea. The only thing it could be is hardware related. :(

    You could try running a HDD diagnostic test using the test from the HDD Manufacturer.

    Does that require getting into Windows?

    Have you tried a /chkdsk?

    Hdd diagnostics from the dell test passed (it did SATA long test), it also did memory pattern tests and they all passed. The computer was functioning enough that I returned it to it's owner. Once it boots up it can browse the web at acceptable speed. YouTube videos even play but it has choppy audio. I have remote control so I could try and find the Toshiba diagnostics for the hard drive, I had trouble locating them.

    I was reading a thread where many complained of DPC latency on the same Dell Studio 1737 model I'm working on. I'm wondering if this is a more severe case that affects performance. It often felt like installations would hang as if they were waiting for something to happen (they never crashed or failed, just slowed to a crawl)
