Installed programs are missing and ReadyBoost isn't available!

Okay, I'm stumped.

When I go under "Uninstall a Program", most of my programs aren't even there. At all. It shows 25 of them, when I have much, much more. I can still use all of my programs (I'm pretty sure!), so what's up with THAT?

Secondly, I can't use ReadyBoost on my flash drive anymore. Funny thing is, the cache file thing is still on the drive and I can't delete it, so I can't use the drive. When I try to eject or format it, it just won't let me. (Says that the system is using it, which makes me think that ReadyBoost is WORKING, it just can't be modified.)
ReadyBoost isn't under the properties tab, and I already tried the 'fix' with seeing if some service was running. It was. I have no idea why these two problems are happening.

I've had this computer for two months, and it's really high quality. Alienware PC.

Help would be EXTREMELY appreciated.

Have you tried 'system restore'?

Yeah, funny thing about that. It only had the most recent system restore from that same day, even when I checked show more system restores.

Yeah...

Have you tried pressing F8 when booting and then choosing from the on screen menu 'Last good known cofiguration'?

Yes, actually. Didn't work.

Hmm... you could try running the system file checker?
If you unsure of the procedure I'll repeat it here. Right-click on command prompt and run as admin'. Then type:

sfc /scannow

Then enter. The file checker will run and if anything amiss is found it will attempt to repair.

Turn off readyboost. It probably slows down your system anyway. Testing shows that hard drivers are many times faster than USB.

...Did you even read it completely? The point is: I CAN'T TURN IT OFF OR ON. The option has disappeared.

Did you try the file checker?

sysmain.dll part of Superfetch Service Host must be messed up. any chance you have a virus?
