Ok big problem, when I turned on my laptop, I always experience a "Not Responding" issue every 5mins of usage, I tried not running any application, cleaned up registry, uninstall unwanted programs etc. I can't even use event viewer. Help me fix this problem. Last 24hrs the laptop are working perfectly, it happened when I turned it off the laptop. I have not installed anything the past 24hrs in order for the system to not work correctly. BTW, if you're telling me to reformat, I can't because my CD-ROM is busted. EDIT: My Laptop is Dell Inspiron 1525.
