Windows 10: system running slow after changing motherboard

    system running slow after changing motherboard

    I just switched to a new motherboard, its an ASRock H97M-ITX/ac. Before I turned off my pc with the old motherboard I uninstalled some devices like the IDE controllers, network adapters, and sound. Then I installed the new motherboard, turned on the pc and noticed right away it was very slow but after a few restarts and installing the new motherboard's drivers it was somewhat faster but I could tell that it still wasnt right. I ran a benchmark on my ssd and got what I think is a really bad result:

    Sequential Read (Q= 32,T= 1) : 19.763 MB/s
    Sequential Write (Q= 32,T= 1) : 12.059 MB/s
    Random Read 4KiB (Q= 32,T= 1) : 6.253 MB/s [ 1526.6 IOPS]
    Random Write 4KiB (Q= 32,T= 1) : 5.544 MB/s [ 1353.5 IOPS]
    Sequential Read (T= 1) : 17.194 MB/s
    Sequential Write (T= 1) : 11.953 MB/s
    Random Read 4KiB (Q= 1,T= 1) : 2.197 MB/s [ 536.4 IOPS]
    Random Write 4KiB (Q= 1,T= 1) : 3.296 MB/s [ 804.7 IOPS]

    I'm pretty sure this is terrible for a SSD. So I guess I did something wrong. Any idea whats wrong and how I can fix it? I'm prepared to reinstall Windows, but thought I'd check in here first because it would save some time if I could just fix my current Windows installation. Obviously a clean install would be best but the time involved in getting everything set up again! argh!

    Sounds like a reformat of the SSD is required -- it may be using a wrong block size. Fresh OS install time and wipe it.

    I reinstalled Windows on a new SSD I was adding to this pc anyway and then I reconnected the old boot drive to get some stuff off of it. My pc decided to boot off the old drive and this time Windows repaired something and its running perfectly fine again. I have no idea why this repair didnt happen before now, maybe I had a bad shutdown which triggered Windows to scan the drive for problems? So I guess I need to decide whether to use the fresh install of windows and continue to reinstall everything or go back to the old Windows install on the previous boot drive. I'm leaning to going with the fresh install but not sure yet.
