Hi guys, need help here.
My system starts to resist me. Hehe.
Here's the problem. Everytime it boots up, scan disk always run by itself but I never scheduled it.
Then things are getting worse; not although scan disk always run by itself, now I couldn't log on to Windows. Whenever I click my user name and instead of loading my personal settings, it reboots by itself.
I tried to remove every start up entry from msconfig using safe mode but that didn't help at all.
One more thing. Suddenly boot.ini is gone. So when the system boots up, there appears a message: " Invalid boot.ini. Booting up from C:/Windows". Everytime I make a new boot.ini, it is gone again in a few days.
What should I do now? Any ideas?
Thanks.
