OMG, what a crap is your process list, Renegade (no offense)
Really, first you have some spyware running:
C:\Program Files\Common Files\CMEII\CMESys.exe
+
C:\Program Files\Common Files\GMT\GMT.exe
+
C:\Program Files\Common files\updmgr\updmgr.exe
to remove them use Spybot Search & Destroy or run Hijackthis full scan (from the main window), then check this checkboxes
O4 - HKLM\..\Run: [updmgr] C:\Program Files\Common files\updmgr\updmgr.exe
O4 - HKLM\..\Run: [P2P NETWORKING2] C:\WINDOWS\SYSTEM\P2P NETWORKING\P2P NETWORKING2.EXE /AUTOSTART
O4 - HKLM\..\Run: [AltnetPointsManager] c:\program files\altnet\points manager\points manager.exe -s
and hit Fix checked
plus C:\WINDOWS\System32\P2P Networking\P2P Networking.exe - it's a Kazaa addon afaik and it's responsible for serious system slowdowns and sometimes crashes. It's installed together with Altnet spyware. So uninstall P2P Networking through Add/Remove Programs.
I would also recommend to turn off all this HP utilities if you're not using them.
That is just a first impession, I'll look into another items later.
