BleepingComputer.com: boot issues

my computer started to have quite a funny issue.
I would try to turn it on and it would not do anything except turn on the lights and fan, and some scanning could be heard.
after holding down the button until it turned off and turning it back on many times, it booted succesfully.
the cd drive will not work at start up in order to reboot windows vista.
i have since done deletions, cleanups, and defrags.
now, it will turn on successfully after turning it on, holding the power button until it turns off once, and then turning it on.
however, this works when the cd drive is not clicked in. so, its out like when one is manually putting in a cd.
internet has more connectivity issues (get kicked off network)
i can't seem to use safe mode.
cpu usage tends to be at or near 100%
it's an hp pavilion dv6000
also,
i am notified that avg is turned off or that windows firewall is turned off.
i turn them on through windows, but they will still be considered off.
i do not get this notification everytime i turn on windows, only sometimes.

Hello whatthelisa,

I see that you have an HJT log posted here: http://www.bleepingcomputer.com/forums/topic227875.html

We do not allow more than one topic for the same computer and the same issue as this causes confusion, and in this case may make the disinfection process more difficult.

This leaves you with a choice:

1) Have this thread reopened and the HiJack This log topic deleted

OR

2) Keep this thread closed and wait for assistance in the HiJack This log forum. Please note that that forum is VERY busy.

Please send a Private Message indicating your choice.

Assuming you wish assistance in the HiJack This forum, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond. Please be patient. It may take a while to get a response but your log will be reviewed and answered as soon as possible

To avoid confusion, I am closing this topic. Good luck with your log.
