Steam constantly validating games

After checking error logs, I've confirmed every game crash to be the result of some kind of computer or compatibility fault.

When I stop the cloud it stops the game from closing itself.

It has happened on two games now: Total War Rome II and Call of Duty Ghosts.

As to why the validation is happening automatically after updates download for these two games.

I don't know, it doesn't make much sense, since the download just happened and should not have been corrupt.

From what I can tell this will happen if I start the game before the sync is done (as in exit, then reenter the game quickly, which I've done a lot lately because while while switching windows the thing freakin' leaves my windows cursor in-game when i switch back, annoying!

FONV keeps crashing when I exit a vendor screen with Chet, 2 different saves1) Ran CHKDSK on drive used, no problems2) Used Steams "Verify Integrity of Game Cache" routine, and 4 times in a row, this happened: Started out fine, chugging away to 67% ,took about 1 1/2 minutes, then jumps to 100% with message "FONV keeps crashing when I exit a vendor screen with Chet, 2 different saves1) Ran CHKDSK on drive used, no problems2) Used Steams "Verify Integrity of Game Cache" routine, and 4 times in a row, this happened: Started out fine, chugging away to 67% ,took about 1 1/2 minutes, then jumps to 100% with message "Your most likely looking at 2 issues here:1) Steam Inegrity Game Cache: You can ignor this.

Steam support suggested it once and it got me out of a problem I had, so I try it again on occasion.

It appears to compare checksums of your local files with the cloud and will re-download any invalid files again.

Every time it starts acting coocky, like not starting up or losing all the colours on the campaign map armies or loading weirdly on a loading screen, I go and validate and sure enough, it has a couple of corrupted files.

(Goes to 74%, hangs, drops back to 50% then tells me files need to be replaced) I don't have this problem of constant corruption with any of my other steam games, but Shogun 2.... Is there any particular reason for this or any way to stop it?

I've also run the Disk Checking tools from my C Drive Properties Tools menu, as well as run "chkdsk /f" which runs chkdsk on boot, neither run showed any errors in the drive.

I've set my BIOS back to defaults with no overclocks and eliminated all but the essential services and programs from starting doing boot, including disabling my antivirus. I'm at a standstill with both Steam and Activision support, and I haven't been able to find anything with Google, so I'm REALLY hoping someone here might have some ideas.

Starting from today every time I start it up, it validates the steam cache files. One time I somehow managed to launch it, then my computer crashed because it was running to much stuff and now I can't get back on at all.
