    I made the mistake of installing an OS on my desktop from a
    Reinstallation disk that came with my Dell laptop. It actually
    worked okay until I installed a Wireless PCI express adapter.
    Things became unresponsive within a few hours of that and now
    it will not boot, even in safe mode.

    I bought a custom built computer. The original OS was Windows 7
    32-bit. I upgraded to Windows 7 64-bit. Here is my mistake. I
    used a Re-installation CD which came with my Dell laptop bought
    a while ago. I used that to install Windows on my desktop. Big
    mistake. My desktop was running fine for a week. Then I
    installed a driver for a wireless adapter and plugged the
    adapter into a PCI express slot on my mobo. It worked at first.
    A few hours later, while editing video, my computer became
    extremely slow. Sony Vegas worked perfectly, but my task
    manager, Internet Explorer all just stopped working. I shut it
    down, which also took an extremely long time. Now my system
    won't boot at all, not with the CD or without it. Startup
    Repair has been running for 12 hours "repairing disk errors"
    and nothing has changed. Safe mode doesn't work. Last known
    good configuration doesn't work. Memory Diagnostic returned no errors. I just closed out of startup repair and it tells me: "Root cause found: System Volume on disk is corrupt." That's the only meaningful thing I've found.

    Specs for my PC: Intel Core i7-2600K, EVGA GeForce GTX 460, Antec Nine Hundred - System Build - PCPartPicker
    *Software is actually Windows 7 32 bit originally*

    OS I put on my PC : http://www.amazon.com/DELL-Windows-

    The Wireless adapter :
    Amazon.com: TP-LINK TL-WDN4800 Dual Band Wireless N900 PCI Express Adapter,2.4GHz 450Mbps/5Ghz 450Mbps, IEEE 802.1a/b/g/n,WEP, WPA/WPA2: Computers & Accessories_
