tgshell.exe and tgcmd.exe are spyware.
VDNT32.SYS and VDNT_16.SYS is the Haxdoor trojan.
agp440.sys belongs to the ATi Catalyst Package and is know to cause problems.
Could it be Rasacd.sys? If so that is the RAS Automatic Connection Driver from Microsoft.
I suggest removing the catalyst driver and clean you system from any malware. (see malware removal section on the page in my signature)
Let us know if it solved the problem.
