Pc is running very slow

[mumairb]

My laptop has started working very slow all of sudden, it takes too much time to boot and do other tadk, I have tried installing Windows 7 again (using usb) but even the installation takes almost 2 hours, what could be the problem and how can I fix it ?

Hello there mate!

Please specify your system information like RAM, Hard drive etc. I would recommend Speccy to pul the system information.
