CPU panic

Question

Hope i'm posting this in the right section, please let me know if not..
for a while now, my macbook is experiencing problems when I try to wake it up from sleep both after closing the lid or letting it sit idle for a while.. Most of the time it will immediately tell me to reboot upon opening the lid.. When it goes to sleep from sitting idle, it will tell me to reboot after about 5 seconds, but it does work for a short time..
The last error:

Answer 1

Have you tried resetting the PRAM and SMC?
Other possible solutions:
Clear Caches
Disable IPv6 in Network preferences
Repair Disk Permissions
Verify Disk
Use Rember to test RAM
If the problem started when you updated to 10.6.6, then either A. restore from a previous system backup before the update or B. Reinstall from your Snow leopard installation disc. It will leave all of your user files in place, only touching system components. Then use the COMBO update to get back to the last OS version that worked for you. DO NOT USE THE NORMAL UPDATE. Combo updates have been known to be much more effective in these situations. All combo updates are available on Apple's website; just Google "10.6.x combo" and it'll pop right up.
Hope this helps.
