Let's see:
1. Find any file with extension .ini or .txt in your Windows folder (for example system.ini) and in the address bar of Inrternet Explorer type c:\windows\system.ini (use the name of the file you found). If all is OK, you'll see a few lines of text. Does it jump, Are the fans revving up, is the PC responding to other commands, can you use your mouse?
2. Now run IE in Safe Mode (http://www.dell.com/support/article/us/en/19/SLN265764/EN tells how, for any Windows PC, not only Dell) and go to www.google.com. Does your laptop react normally?
