My first post is a long one. I suppose others have joined this forum needing help from the start. I have had this Sager notebook for just over as year and it has been quite problem free until this. I first got a taste of it a couple of weeks ago but a few restarts got it back to what seemed like ok. A few days ago it came back to stay more or less. I have considerable experience with computers and could fix about anything on the older operating systems but I'm not that familiar with troubleshooting Vista because I have never needed to until now. Thanks in advance to anyone who will wade through the following and give me some ideas.
Problem Description:
Shortly after I connect to my wireless network CPU usage goes to about 50% according to task manager. Another CPU monitor shows one CPU at 80%-100% and the other at 30% to 50%. If I have not already started task manager I am out of luck. When I try to start it the icon appears in the taskbar but it will not show on the screen. Graceful shutdown is now impossible because the system hangs on the logging off screen.
If I have already started task manager and set it to show processes for all users I can see an instance of svchost local service using about 50% of the CPU facilities. Right click on the process and selecting 'go to service' takes me to the audio driver service.
If I end that process the CPU usage goes back to normal and the speaker icon gets a red X for awhile but soon the process restarts, CPUs go back to chugging and the red X disappears. If I go through this three times the audio restores but the CPU's remain normal and everything seems ok after the third time.
Before I figured out to look at all processes in task manager and deal with this runaway process recovery was very time consuming. Simply starting Windows normally brought the system up with the CPUs chugging even if I switched off the wireless. Booting in safe mode eventually took me to a black screen with 'safe mode' on the corners but no icons, taskbar, or any way to interface with the computer. A forced power down from this screen followed by a normal startup would get me back in without the CPUs chugging until I make a wireless connection.
Thinking it was the wireless hardware I switched it off and installed a USB wireless adapter but that gave the same results as the built in wireless adapter. I can connect to my router with a cable without these symptoms and I can get on the net without them using my AT&T air card.
Temperatures on this notebook seem ok to me. CPUs about 112F at idle and about 129F when chugging. The Nvidia 8600 graphics adapter runs at about 155F but I think that is normal. The disk shows about 105F.
For awhile the system would frequently fail to awaken from sleep mode but that seems ok for now.
What else I have done to try and sort this out:
Removed and reinstalled Intel Proset wireless drivers and software.
Removed and installed updated Realtech audio drivers
Full Chkdsk testing every cluster...found no problems
Full memory diagnostics...found no problems
Intel Proset diagnostics...found no problems
Full virus scan with completely up to date Nod32 definitions...found no problems.
Somewhere along the way the Turbo Memory Readyboost and Readydrive settings went to disabled but I now have them enabled again.
I think that about covers what I have done. Any more ideas?
