Wall of text incoming. PC problems, what else?
One thing in the PC world that I seem to have issues every now and then are the fecking USB ports! I don't know what it is. In theory they are great, a de-facto standardized way to connect about anything to a computer, from mice and gamepads to USB modems and hard disks. You can be always sure pretty much any PC has them, and even many tablets etc.
Earlier, I had serious issues with them both on my old laptop (now scrapped) and the old desktop. Specifically with USB hard disks, those systems might just suddenly decide that the hard disk was not connected anymore, even during a big file transfer. More than once, the whole fecking NTFS file system of the external hard disk became corrupted due to that, making the whole hard disk unreadable.
Back then I tried to google about the issue, and some others seemed to have the same problem (there was a certain error message which I forget now), but it was never fully clarified what was the root cause. Some analysis pointed to some Win2000/XP USB drivers, and others to certain commonly used USB hardware parts which were simply faulty by design.
Back to this day. For quite long, I haven't had that much issues with USB ports anymore, e.g. on my T400 laptop. But, due to a hardware design fault, the USB ports on this Lenovo T400 seem to be very fragile, hence one (out of three) USB ports got broken from normal use quite fast. The plastic part inside the USB port just cracked and fell out. Googling for it, this seems to be some quality issue on T400 laptops, many T400 users have had the same problem.
Ok, so two USB ports isn't quite enough for me (and I am not supposed to use the broken USB port anymore, as the pins might now get bent, and cause a short circuit, making the whole laptop fail to boot... or so says the google), so I bought an USB ExpressCard providing two additional USB 3.0 ports:

It seems to work quite ok... except when it doesn't. The old times are back. If I have a mouse connected to the ExpressCard USB ports, after a couple hours of use (or sooner) it just might become unresponsive, as if the mouse is not connected anymore. It doesn't seem to revive unless I restart the whole computer, and at least twice has happened that if I try to remove the ExpressCard with "Safely remove...", the whole machine hangs.
And once it indeed happened that while one of my USB hard disks was connected to those USB ports, it lost the connection suddenly. That caused a forced chkdsk by Windows on next reboot, but apparently the hard disk filesystem was still ok.
I don't know, but the whole USB thingie seems somewhat flaky and unreliable to me for any serious use. Maybe some asswad wrote the USB specs, and now I have to put up with it? Maybe I should use it only for connecting non-critical stuff like mice and gamepads, and more important stuff like external hard disks would connect only through eSATA or whatever. But there doesn't seem to be any universal option for USB.
