My dell laptop is very slow, I can't watch a full movies on it cos it keeps breaking out. Could anybody help me solve this problem

I would start by downloading free CCLEANER at :http://www.filehippo.com/download_ccleaner/ Install and run. The scan will clean the junk from your system. Also there is a section TOOLS , STARTUP, to disable programs from starting at windows boot. ANOTHER program MALWAREBYTES FREE at :http://www.filehippo.com/download_malwarebytes_anti_malware/ Run A FULL SCAN delete ALL results. I don't no the model of you DELL so I don't know the specs. But you want to disable ALL programs not needed . In Services you can disable Windows Search, a memory Hog. Only you can choose the programs that are not needed, I have no clue what is on you machine. Take a look at this for tips: http://www.pcmag.com/article2/0,2817,2364937,00.asp
