Well, my computer as a whole has been a little wonky lately (taking a full minute to load up a song in VLC player, for instance) so I'll give it a shot.So, when I want to play TF2, it comes up with a window saying that "Steam if validating files".I've already tried every other bit of advice I've run into, so what's to lose?
I would use chkdsk at this point to see if you have any bad sectors on your hard drive.
It was only my Steam Partition, and not my main one.
It was most likely due to me downloading several games off steam at once.
Try as I might, I simply cannot get the damn game to just let me play.
That's exactly the problem; Steam won't stop verifying the cache.
I tried reinstalling the game at least four times to no avail (it did let me play once, but it had horrendous stuttering issues), and I even tried reinstalling all of Steam twice.The game refuses to do anything past validating files that have already been validated, and getting an update that I already have (which I know from the brief stint mentioned above).I did decide to do it manually like you said, but that didn't do crap.So **** it, I'm just going to reinstall the entire game for the FIFTH TIME to see if that changes anything.I don't have access to any TF2 maps in Gmod, so my guess is that something messed up when installing (I did get a random blue screen right the **** out of nowhere today when it was at 100% (with 100% apparently not meaning it's done) so that could be it).What I did:-Backup Local Files to an external memory drive-Delete all local content-Restore the back up-Play TF2Considering you reinstalled a bunch of times, not sure it'll work.
