Deep Scanning My Laptop

Hello!


I have a question about the way my computer is "acting" lately. I can't put a finger on what it is, but it is subtly affecting my computer's performance. I have a Dell Inspiron 5520 with Windows 7 and am unable to install some of the drivers necessary to run, for example, my CD-ROM and my card reader. Also, my computer has been running sluggishly the last few months, it sometimes freezes up and programs often open slowly. I'm wondering if it needs a REGISTRY CHECK or some kind of DEEP SCAN to check for possible viruses or malware. Can you help me with this? Any help you can give me is GREATLY appreciated.
