Solved CPU @ 100%, Memory Used Up & Drives/Thumbnails not Showing Win7

[WikdGTO]

so yeah, this problem just started few hours ago.. out of the blue, noticed my CPU was running at 100%, so i figured it was some weird script running from my browser, so i closed it, re-opened it, but didn't work. even rebooted system, and it came back, still at 100%. then i started noticing my thumbnails in folders weren't showing up, or loading. even my hardware drives are not showing up. you see the progress bar at the top loading, top of folders.. but nothing ever happens. no thumbnails, no drives. then i noticed all my Ram is being slowly gobbled up.. i have 6GB installed, but right now it's showing i have only 275mb free! what!? i really don't understand what's going on here.. i've rebooted a few times with no luck, and even restored my system to an earlier date, but still no luck.

hope someone has heard of this before, and maybe have some ideas! this is freaking me out! i was just going to do a whole system restore, but i can't backup or move any files to my ext hardidrive cus my drives aren't showing up! it's actually sporadic, but when a drive does show, i still can't move a file from main drive to the ext drive.. nothing happens.

Update: i've noticed in Task Mngr, that this thing called dllhost.exe and Com Surrogate are using a lot of the CPU.. i can end it and the CPU usage temporarily drops, and memory usage is lowered too, but both soon returns to 100%. not sure if this process has anything to do with anything, i don't even know what Com Surrogate does, but this is all a nightmare!

please help if anyone can, thanks

Have you scanned with your Anti-virus program?

oh yeah.. but i think i solved it already, and i feel stupid! i noticed on another thread someone with a similar issue, they said something about a weird wav file that Windows didn't understand or something, and the system was constantly trying to access it. deleting the file solved the issue they said.

so i looked in my temporary downloads folder on my desktop to see if anything there may be the culprit, and turned out to be this 3D Star Trek trailer i downloaded from Youtube, in MP4 format. i guess if this was the problem, Windows didn't know how to deal with it, or something. i hoping this was the issue! cus deleting it has made dllhost/Com Surrogate go away, and my memory and cpu usage is back to normal.

crazy stuff, and scary too! i hope this never comes back, if it does, i'll update, but everything looks ok now, thanks
