I'm having the same issue with Kingston HyperX 3K. I've had the drive for about 3 months now. The issue started happening about a month ago. Often, when I open Computer folder, the disks don't show up, the bar goes across for a minute or two and just gets stuck at the end. Changing sorting order in folders causes the same bar running across and nothing happening. I have a couple of hard drives in the system. The problem occurs with folders on those drives as well. I'm guessing it's some I/O hiccup that locks up certain functions in the background. Since the OS in on the SSD, it screws with everything. Once these issues start happening, my icons don't get updated - if I open a folder with files of the type that has not been drawn on screen since reboot, those icons will be blank/generic/white as for unknown files. Once I reboot, that folder will show up correctly. I'm guessing they get cached somewhere, and as long as they get cached before these glitches activate, they will show normal.
Also, once weirdness starts happening, I noticed this: open Computer folder - observe empty window with perpetual refresh never completing, shut computer down (either Start menu or Power button), the second before explorer closes, the folder shows all contents and disappears. So once shutdown command is sent, some handle closes and unlocks w/e is causing this crap.
Would really like to know wtf is going on. Might play with SysInternals tools later to, hopefully, get better understanding.
P.S. check disk with "/r" didn't help. "sfc /scannow" didn't make any difference either. This Windows 7 install is as old as the SSD (~3 months).
Problem solved. It was caused by Acronis 2013. What an intrusive POS software that is. I remember having issues with 2011 and 2012 in the past because it would integrate itself as a service, into context menu, into Windows Explorer, and other areas. It would interfere with 3rd party software and create massive I/O overhead unless you killed off a bunch hooks with Autoruns. I'm so angry and relieved.
Hopefully, this will be helpful to someone.
stan you are awesome
i had noticed the same thing on my new ssd drive
just uninstalled acronis and everything is back to working fast again
