are you connecting it to a hub? While today's stuff is considerably better some devices just do not like hubs, connect straight into a hard connector on the motherboard see what happens. Also...windows gets confused sometimes, try plugging into another usb port which "should" force windows to reload the drivers for it. When you say "doesn't work after startup" do you mean that the mouse is not seen from the screen where you put in your password or do you mean that after windows actually starts up that it doesn't work right away? You're just dealing with a MS$ product it might be a driver conflict a registry mess or even a malware try something like ccleaner or one of the other myriad of utilities that clean malware and fix bad registry errors.

You should be able to make the gas cartridge come off the bottom of the chair but it may be a little bit of a job. Most likely you will have to unscrew the bracket from the bottom of the chair and from there you should have access to the top of the gas cartridge, from here it could be easy or difficult, you will probably need a hammer and a punch sort of long metal thing that you can strike with the hammer on the top of the cartridge to push it out. You'll need two people or a bench with c clamps that can hold the chair while you insert the punch in the hole and hit it with a hammer. Obviously don't go hulk on it but you should be able to just pull upwards and the wheeled base will come off but getting it out of the chair bottom is the tough part. All office chairs are the same way to get the gas cartridge out. If it turns out to be a bad cartridge you can order replacements on ebay not too expensive unless you need one of the heavy duty ones for big folks and it doesn't hurt to order the ones for the big folks if you don't need it because they should last longer because they are made for more weight. I think I paid 40.00 for my last gas cartridge for 300 lb capacity. You will need a couple of measurements to get the right cartridge if they don't have a model list a good listing will show you where to measure etc. You also need to know how long the cartridge is, doesn't hurt to get a longer one unless you're a short person, too high you can't put your feet on the floor anymore. It looks tough but it's not I've changed them on several chairs a lot cheaper than a whole new chair and cheaper than shipping it back too!!!

Same issue here, I think it's an issue with win 10 and certain chipsets. My main box is a gigabyte 990fxa - ud5 with a 9370 on it, corsair h100i cooler, corsair mouse, external blue ray burner nvidia 1060 video card, 16 gig ram. 1 terabyte wd ssd drive. there is not much software on here I was trying to see if the issue returned after a full reinstall of windows 10. I found a chipset driver update on the amd site that gigabyte doesn't have on their website (probably because it's an old board now). That seemed to help but the issue returned. I have a razer mechanical that I just returned for what's probably the same issue, it is working fine right now. An older roccat board also did it and a cheapo usb mini keyboard I had for a gaming console was fine at first now doing it to. Random characters wild spacing across the screen, no backspace or shift just all sorts of fun stuff. The weird thing is this started when i installed my netgear gaming router, it had some sort of idiot proofing running during the install, I saw it running and seem to remember some opinions that those utilities are really just malware that cause issues but even after the reinstall when that stuff should be gone it still happens. In the ancient days when you had to be concerned about interrupt (IRQ) conflicts my instinct would be to wonder if something like that was going on but that should not happen in these modern times. Please fix my keyboard I hate that other product that I have to use until this is straightened out. Before you ask the problems occurred before the corsair utilities were loaded so that is not all of the problem if you ask me. Acck annoying crap to say the least.
