Since I like to keep my pc clean. I regularly uninstall idle apps. At the same time, I try to keep my hard disk as healthy as possible. I heard that defragmenting from time to time is highly recommend for every PC. Can anyone tell me how to defragment? Also I heard that defragmenting can be done by third party apps as well. How can I fix bad sectors if detected on my hard drive?

Hi, being a hardcore game, i have recently started hearing about the use of SSD hard drives to speed of the processing speed in laptops and desktops. What is the meaning of SSD hard drives.

I have a Toshiba X875-Q7190 laptop. It has a GPU built into the CPU and a discreet GPU. With some fies, particularly PDFs, it takes a tremendous amount of time to render successive pages.

I read about Google's Project Tango which says Google is developing a tablet/smartphone focused on developers interested in 3D sensing and similar applications. Are there currently any other tablets which can be used for that purpose? Because apart from the memory and processor , a lot of tablets have similar specs so I wanted to try my hands on 3D sensing using existing hardware on the market. Any suggestions (tablets) ?

I assembled a new PC with the Motherboard being of Gigabyte. The CPU has 3.5mm headphone jack in its front as well as at its back. I usually watch movies in my PC and if I plug the headphones at rear side the wire is short to reach my ears. So when I plug it in the front 3.5mm port there is no sound coming from it. It even doesn't recognise the dvice. I have checked the cables. All are attached fine. Front USB ports are working but headphone port is not. Please help.

My new Sony Vaio laptop is facing a Wi-Fi issue. I'm running Windows 8.1 Pro x64 and it keeps on disconnecting. The odd part is that, sometimes, it was working fine the whole day. Next day, it will act strange again. It even restart itself automatically. If you have a solution, then tell me, I'll be very thankful.

Recently, I've got my new DSLR camera. And I am kind of new to this thing. When I used it on a family reunion, I noticed that I can only focus on a certain subject. I have a large number of family members and I want to know if its possible to adjust the settings so I can focus on the whole image?
