Irregular behavior entering sleep + iMac freezes in verify disk

Question

My iMac (Core 2 Duo, OS X 10.4.10) is having some sleep issues. When iChat is running and I put it to sleep, it makes the iChat disconnect sound several times (and in a very scary way), and only then goes to sleep. When I wake it, a gray screen appears for a second, and only then the machine comes back.
I ran the Verify Disk command in Disk Utility, and the Mac froze, forcing me to shut it down through the power button. I then booted from Install Disk 1, and ran a verify disk command from there. It showed no problem, so I booted back to my main drive, and the sleep issues continued. I tried to run Verify Disk again(form the main drive), and the mac froze again.
The only thing I changed was deleting some .plist files from iChat, since it kept disconnecting.
I really have no idea what to do next. I would really appreciate if someone could help me to solve this isuue.
Thanks,
Omer.

In order for iChat to stay connected and running the computer needs to stay awake, when you go to the drop down menu and select sleep it puts both the (Display and Computer) to sleep.
On that note there are two thing you can do:
1. Quit iChat befor sleeping the computer from the drop-down menu!
2. Leave the computer awake and only sleep the display, how you ask?
