CPU slowed down by other processes

For almost a week now I've had a very frustrating problem where my cpu is slowed down by Explorer.exe taking up all the leftover space from most anything I run. I found out when I was playing the game "Team Fortress 2", where the game would suddenly undergo a huge amount of lag almost freezing my game for about 30 seconds at a time then play smoothly, progressively getting more frequent as time passed. I know it is not that my computer cant run it because it will run perfectly smooth as I pointed out earlier, and I have learned that it even does this to simple flash games on the internet or even when watching videos. So I checked my task manager at these points of lag and found Explorer.exe was the culprit, or so I thought, because when I ended the process (my desktop disappeared as to be expected) the lag intervals would still happen, with some processes called dwm.exe and svchost.exe taking up around 30-50 of my cpu (usually dwm.exe) and I cant even close these. I have tried scanning for viruses (nothing showed up) and have been looking for a solution on the web for the past few days to no avail. Any light shined on the subject is appreciated and thanks in advance to any help on this very annoying issue.

Scan for viruses, spyware & malware. All scans should be performed from safe mode. You should also disable all useless programs from loading at startup...the less loading at startup & running in the background, the better. I have no idea what you have but here's a short list of items that do NOT need to pre-load:

Adobe
AIM
Yahoo
Google
iTunes
QuickTime
RealPlayer
WinAmp
Printer/scanner/camera

You should also install a cleaner such as CCleaner-Slim & use it regularly.

Thanks for the help, I have already disabled useless startup items, but how do I go into safe mode in order to scan from there? And how do I get out of it (so as not to be stuck in it forever)

Start the system and tap f8 then select safe mode.
How to exit? Just restart the system.
