Here given information you need to walk into electronics store and know what you are after and how much you will be costs.

Instructions
1. Choose what you will actually be doing with new PC. Will you be editing photos and videos? Will you be playing 3-d games? Or will you just be surfing web?

2. Choose where to purchase it.

3. Know the fundamentals. For many people there are some important things to know about earlier than making decision. How much RAM you want, how much Hard Drive space you need, the size and weight you want, if you want a graphics card, and what kind of processor you want.

4. RAM Needs. With launch of Windows 7 standard on RAM has become 3 GB which is above enough if you only run some applications like Internet Explorer, Microsoft Office, and Windows Media Player. 4 GB’s and up is going to be for a broader array of applications and probably gaming. Usually more RAM you get faster Laptop will run. Also know DDR2 and DDR3 Ram is obtainable DDR3 is 50-60% quicker than DDR2.

5. Hard Drive space. This is overvalued part of PC. People always want large hard drive but 90% of people do not need anything special. Many laptops will come with anywhere between 250-500 GB of hard drive space. This is enough for everyone. All hard drive really is place where all is saved. Music, photos, videos, applications, documents, all saved here. Don’t stress too much about it.

6. Laptops having sizes from 12.1" - 21" but ordinary sizes are 13.3", 14.1", 15.6", 16", and 17" weights will vary from 3-8lbs.

7. Graphics cards are somewhat that CANNOT be included afterward to a laptop, so if you want to play games or edit photos and videos, you need graphics card. Devoted graphics is best and search for an Nvidia or ATI sticker on laptop to see if it has devoted graphics.

8. Lastly processors are usually 1 of 2 different makers either Intel or AMD. Intel has processors from Celeron to Core 2 Quad processors. AMD is usually Turion and Athlons. I prefer Intel since it's quieter and gets better battery life. As AMD generally has better gaming performance. Pentium will be slightly cheaper than Core 2 Duos but won't have similar speed or performance.

9. Mainly if you are like many people and just want to run some things you should not be using more than $600-$700 dollars. Ensure you give service plan some thought, and get manually some antivirus and anti spyware software.
