First step in this sort of thing is Checkdisk. http://support.microsoft.com/kb/315265
Open "My Computer," and right click the main local drive (Windows installation), usually C:\ Please select Properties
from the list, and when the new dialog opens, choose the Tools
Here, press the Check Now
button, mark both boxes, and click Start.
Windows will tell you that it can't start now, the disc is in use. Do you want it to check the disc on next boot. Yes.
A black screen with white writing will keep you informed of the incredibly slow process of checking your disc for errors. Any errors found will be fixed if possible. When complete Windows will boot normally.
Next step is to do "scannow." http://www.updatexp....cannow-sfc.html
Follow the instructions carefully. The Run
command requires the "space." Best to paste it in. Insert your Windows CD when asked, and hit "Retry"
as often as asked.
Step 3 is cleaning. ATF Cleaner is excellent, and requires no installation: http://www.atribune....tent/view/19/2/
Save the download to your desktop and double click to run. The first time "Select All." After that it is usually best to leave "Prefetch" and "Cookies" unchecked.
Step 4 is controlling background processes. Rather than repeating everything here, please see my Vox post: http://doc1101.vox.com/
The "links" are not "live." To view the referenced pages, copy and paste the URLs to your browser address bar and Go.
Whatever else you do, get ERUNT and WinPatrol.
And step 5? Forget WMP. Just use VLC: http://www.videolan.org/
All this, of course, assumes that the problems are not malware rellated. If you suspect malware, or if any of your scans have reported anything more than tracking cookies, go immediately to the malware section of the forum: http://www.geekstogo...-Log-t2852.html
