I am sorry if this is not the correct place to post this but I have already tried using the steam forums and opening a ticket and I would like to get input from as much people as I can to help me fix this issue if possible.

I cannot remember when this started happening ( think maybe around a week or two ago) but CS:GO had an update and I noticed that it was stuck on 99%. I ignored it for a while but eventually decided to investigate why it was stuck. I tried uninstalling then reinstalling CS:GO to see if that would fix the issue, but it did not. Then I tried deleting the game's directory and reinstalling but that didn't help either. Next I tried googling the issue and found a number of different things to try. I power cycled my internet (which was working fine throughout the duration of this), reinstalling steam by deleting everything but my steamapps and steam.exe, disabling background applications, changing my download region to different states and countries,launcghing steam with the "-tcp" command, using the "flush://steamconfigs" command, renaming steamapps and letting steam create a new folder and deleting/renaming the clientregistry.blob (how ever, a new one was not created afterwards but I read something about how steam doesn't use it anymore) and pausing/resuming the download and NONE of these fixes worked.

Someone told me that it might be a Hard Drive issue (something about how the sectors for steam might be bad), so I ran CHKDSK and the Western Digital Diagnostic tool (I have a WD Blue 1tb) and after both tests I got NO errors for my hard drive. The only thing that I did prior to my HDD was do a defrag and cleanup the registry with CCleaner.

I've tried installing other games and I noticed that I get the "Busy writing to Disk" message when installing games,but I heard that was normal. Either way, the same sympotoms for CS:GO happen with everything else.

I can install other programs and games off the internet or from other companies (Like Origin) just fine, Only steam seams to be affected.

What is my issue? I feel like the last steam update caused my steam to screw up, should I wait for a new update to come out?

The ONLY other issue that I'm having with my PC is that sometimes on startup I will BSOD, it will restart and boot back into desktop and after that I will have NO errors whatsoever (only on startup sometimes). I've asked on Sevenforums about this and I already ran my PC through several checks and the moderator basically told me I should do a clean install, but im gonna do that ony my SSD when if I get one soon. other than this, I have no other issues with my computers, no randoms BSODs, no crashes or anything.

once again I'm sorry if this isnt the type of post that's welcomed here, I just wanted to ask as many people for help if I could to fix this issue cus I really don't want it to get worse.

Edit: All right I feel dumb. When I came home from school I thought to myself "instead of power cycling your modem why don't you just reset the entire thing?". So I did and now everything download with no problems.
