Hang @ shutdown System.ini problems

[ryoko]

Bought a new HP dx2300 XP Pro system @ Newegg for my Dad.
Uninstalled some "trial programs" from the hd- MS Office, Symantic antivirus, etc.
Loaded open office,AVG,spybot, adobe 8, installed old modem card Aztech MDP7800-U from his old Win.98 system (XP gave it a lucent driver and says its fine - nothing in device mgr)
Everything worked fine until it connected to the internet. Something communicated and now the system hangs @ shutdown.

Looked at event log, device mgr. hardware etc. Finally went into msconfig to diagnose this.
I know how to play around with start-up programs but nothing about system.ini

These are the files I found that make the system hang at shutdown:
(shutdown=lockup of mouse/keyboard, must hold pwr button in to manually turn off)

for 16-bit app support
wave=mmdrv.dll
timer=timer.drv
mci
driver 32
[386enh] area where the following files hang the system:
EGA40W0A.FON=EGA40W0A.FON
CGA80W0A.FON=CGA80W0A.FON
CGA40W0a.FON=CGA40W0A.FON

Would any experienced system.ini person be able to help me in defining what they are, and how to "fix" system.ini from hanging at shutdown?

I have them turned off in his system now - hate to screw around wtih a new system that there should be no issues....
Thanks for your replies!

Went over to check on the computer and found it wasn't shutting down again. Found I have to disable ALL of system.ini. Again no problem with Start up, Services, or win.ini. Nothing in device mgr. Event viewer. etc.
I was horrified to discover that system restore was turned off when we received this computer. I didn't think to check it was enable when we received it.

This is where I hate buying pre-packaged software computers.

Does anyone have exp. with the HP computers on these recovery disks, etc. I created all of them upon receiving computer. I assume I'm going to have to go back and load them up hoping this will fix the system.ini.
