My laptop freezes after start up. I start the computer and it runs normal until right after log in. I have roughly 30 seconds to 1 minute after logging in before the fan turns on and the laptop starts getting quite warm on the bottom. At this point the computer runs extremely slow and stops loading anything that may have been running. Also, I cannot start the laptop in Safe Mode... when I try this it restarts and brings up the screen asking if I want to open in Safe mode, Normal mode, etc... all over again. It boots fine in normal mode until right after log in. eMachines 6805 w/ XP.

Try disabling wi-fi device.it's probably pci-e if it is built in.i had this problem in my thinkpad t500.when i log without enabling wi-fi.it works great.when i log with wi-fi enabled.it stays about 1 min then freezes.right now i changed power settings for pci-e and now it seems working fine. try this

When was the last time your computer worked fine? run system restore and choose a restore point prior to when the issue started. if no restore point is available, open run and enter 'msconfig', go to startup and disable unecessary startup programs. also open the prefetch folder and delete its contents. then restart your system. if it's still slow, i suggest you backup your files and reinstall windows. make sure that you operate the laptop on a flat surface to avoid any ventilation blockage. hope it'll help. good day. =)'

Solve this problem by:

-- cleaning system junk
-- optimizing computer services
-- optimizing internet
-- repairing registry
-- defraging registry
-- clearing browsers junk

do these things with some secure tool such as Intel Software Partner Reginout.
