Few things to take into account; how much RAM do you have installed? What is your processor speed? What is your graphics card?
Any computer should have at least 2GB RAM depending on if you have Vista, 7, XP etc. If all you do on your computer is word, internet and simple stuff like that then 2GB is fine. And a 2.00GHz processor would do.
If you do more serious programming like Photoshop, games etc. Then you should have around 6GB RAM on a 64 bit operating system (of course). There are heaps of processors you can choose from. From AMD, Intel, dual core, quad core there’s heaps. Right now, I would go for Intel dual core (not quad because most programs and games can only use 2 cores anyway) the i7 processors are good I think but I’m not sure because I haven’t used them. As long as you have about 2.6GHz speed, you’ll be fine. I have 2.00GHz and it’s ok until I do video converting (so I do wish I had a faster processor).
Let’s recap. Around 6GB RAM, 2.6GHz processor (probably Intel dual core), so that’s what we have so far. They are the most important things in a computer. But a graphics card is also important. A lot of computers will have a shared graphics card. These aren’t very good. If you buy a computer online, you can usually customize it a bit. (Again, if you’re doing simple stuff, word etc then go for a 512mb independent graphics card) Try and get 1GB independent graphics and even more if you’re doing hard-core 3d gamming.
Now, there are a few graphics cards out there that you can choose from. The 2 most sold are Nvidia and Ati. I (and most other people) prefer Nvidia. Especially the Nvidia GeForce.
So, so far we got the RAM, processor and graphics card. They are the most important things. Once you have those, you will be fine.
You can then however go onto things like Operating system, Hard Drive, CD/DVD Drive, display and Networking.
Having said all that, if you recently bought a computer and it is slow, there could be hundreds of reasons; virus, not enough RAM or maybe it’s just a lemon.
If you think that you have a virus, do the following.
Download Malwarebytes anti-malware from download.com
Perform a full scan. (Note: A quick scan can take from 2 minutes to 20 minutes) A full scan will usually take at least an hour on most computers. And most of the viruses found are found towards the end of the scan. Once it’s complete, click on show results and then fix or delete or whatever it says. It will (or at least should) get rid of the viruses found. Then you have to restart your computer.
To be sure you got rid of all the viruses you can download Avast! Cleaner or buy Avast! Pro. Avast! Is good because it scans the memory for active viruses which may prevent you from finding them. Scan, and fix the problems found.
Viruses can get into your computer in many ways. From going on dodgy websites, via USB, too many programs running.
So try to eliminate the amount of icons you have running in the background. Look at your taskbar in the bottom right corner. If there are a lot of programs down there then try to get rid of some of them. For example if you have Bluetooth running, sync, touchpad and other totally pointless programs, right click and get rid of them because they will slow down your computer. Maybe you have downloaded limewire and it starts when you turn your computer on. Turn it off. Limewire uses a lot of RAM (and can easily give you viruses). To stop programs from starting automatically, press windows key – R and type in msconfig go to the startup tab, you will get a list of programs which start up with your computer. Any programs you know you don’t need un-tick. If you’re unsure, google it. You can also go to the Services tab (Make sure you tick Hide all Microsoft services down the bottom) and then google in any you are unsure of.
If you don’t think you have a virus, maybe you have a registry problem. Download Advanced System Care. There is the free version (which is good but obviously not as good as the paid version). Download it from download.com
Install, Scan and fix. Any of the problems found can be repaired without damaging anything on your computer. This is a very good program which will almost guarantee you a faster computer.
An even better program is TuneUp Utilities. However the free version is only for 30-days. So either clean your computer with it and then forget about it or download the hacked version. (You can go to youtube and there are many ways of doing it).
This program is especially good because it defragments your registry. Do all the scans and turn on Turbo Mode and it will definitely speed up your computer at least a bit.
If you have vista, you can go to My Computer, then at the top you will see a tab called System Properties. Click it, then on the left there is a tab called Advanced System Settings. Click it, from there go to settings under performance, and click adjust for best performance. You won’t have all the fancy 5 looking icons etc but it will
