How to test your computer hardware failure
-First of all i want you to test and exhaust all software troubles before you move on hardware testing failures. Testing your hardware can be real pain if you don't know how it manifest itself and where to look at first place. I will show you how can you determine which piece of hardware causes you errors.
-So here we go one by one:
-Hard drive failure (HDD)
All errors which include moving, copying, reading, deleting or OS is unable to boot are main HDD problems. Also if your computer start to loop in circles can point you at HDD failure as well. First of all you need to use software to test your hard drive because some of this errors can be caused by another piece of hardware so you need to eliminate hard drive at first place. Use any of these software: HDD health, Test disk, Scandisk etc.
I personaly encountered one weird situation where HDD was bad, it boot slow and can only acces bios after 10 minutes and when in bios every move have a delay of few seconds. I replaced HDD and my problem was gone. At first i tought it was bios failure so i tried changing cmos baterry and flash bios which didn't gave me any results in process. I replaced HDD followed with new OS and everything worked like a charm.
-Memory failure (RAM)
Here is a list of errors you can get with bad memory chips: random reboots, pc does not boot at all, installation failures, blank screen, fatal (errors, exceptions and messages). If you suspect that your memory is damaged by any means you should check are they stay correctly in RAM slot and if there are more then one you should pull out one by one and eliminate damaged RAM. Also in some cases you can encounter our old friend called "Blue screen of death".
-Motherboard and CPU failure
This is worst scenario you can get in computer world and in most cases it ends up with changing completly your motherboard. There is numerous number of errors you can get when this issue happens and i will count few of them: pc does not boot, loophole, beeping sound, blue screen, several error messages after sucessefull boot and so on. You can use some software to test your motherboard but that's only case if you succede to boot your OS. Hot CPU tester is best tool to do such research.
My personal advice (use only if you are really sure all other options fails because this can cause irreversible damage) is direct heating of motherboard bridges (use hair dryer). Direct your heat source to GPU for about 60 seconds in circular motion and avoid by any means heating plastic parts or RAM slots! Of course you need to remove memory modules first and motherboard must be pulled out of computer. Again i warning you do this only if you think this is your last option and your motherboard doesn't have guarantee list for repair.
-Power supply failure
Here we have few situations you need to consider before you diagnose power supply failure. Power supply can be damaged by higher force (thunder and other high voltage strikes). Best thing you can do is to change your power source and keep going. Keep in mind that all other components of your computer are conected to your power source and they can also be damaged if you try to do some kind of tests on it. It's best that you only change power source supply to prevent more damge to your pc including the motherboard (check post above) which is worst scenario that could happen. There is no such software to test your power source integrity but if it still works you can use program who can monitor the voltage and power supplies to the fans. If you are not experienced with such hardware problems leave it to experts and they will do it for u.
Second problem can occur when you buying new complete pc configuration. As you already know every component of your pc use some power in order to work properly and here is great site where you can summerize your power supply usage for each of the components. If your power supply is not strong enough to supply all the components equally it will reboot as soon as you turn it on or it will not start at all, so it's very important that you calculate perfectly.
-CD-ROM and DVD drive failure
Before we begin with testing you need to make sure multiple disks nit working in the drive and by multiple i mean CD or DVD of the same kind. If DVD works fine and CD causing you problems then your drive is ok and problem is in the disk itself.
Your disk drive is damaged if you see errors like this: CD or DVD reading error, can't play any media files (audio, video etc), error when installing something from disks etc.
There is programs made for testing such problems and also there is CD or DVD cleaner if drive lens is dirty. CDRoller can be helpfull and also you can recover some lost files on damaged disk. And CDCheck is also nice software where you can recover lost files, and it's known for it's stability, ease of use and good support as well.
-I hope this article will help you in future and i apologize for some gramatic mistakes in my writings :)
Cheers

WordPress and Google Maps
-In this article we will get closer with Google Maps service application provided by Google. It's coded in JavaScript and XML and it's available on desktop and mobile edition. It's user-friendly mapping technology where you can get all available infomations and directions with just few clicks of the mouse. After all it can serve you as driving direction which is one of the most common use of Google Maps and also as trip planner or even the current traffic situation.
-Google Maps covering all continents, countries, administrative regions, cities, etc. World Route Planner and Maps will also provide users with time zones and daylight map, giving you accurate informations for your travels or curiosities. And last but not least we have Google Street View where you can take a look on places you never seen before like Statue of Liberty, Pyramides and other places by your choice. Though Google blurred people faces and license plates for secutity and privacy reasons.
How to add Google Maps in WordPress
-If we want for any reason to add Google Maps in WordPress there is several ways to do so. So lets explain how to manually add Maps to WordPress and by manually i mean embedding Google Maps in WordPress post. First we need to visit Google Maps and make a search with desired location (just type location by your choice like street address or whatever that fit your needs). It's best that you wait for map to be fully loaded before proceding to the next step. When map is fully loaded check for gear icon in bottom right corner and click it.
You will be presented with option share and embed map. Select that option and popup window with embed code will appear. Select and copy code to clipboard (code begins with <iframe). Now go to your WordPress and navigate to section where you want to add Google Maps (post or page). Now open text editor and paste code directly into your post or page. Save your work and first thing you will see that code was changed and thats because WordPress converted HTML code into working code.

Improve WordPress default image quality
It’s well known that a picture says more than 1000 words so there are many webmasters or site owners who are using thousands of images at the site. Still there are people like artists or photographers who want to show off their work and use many images. Of-course that they want to show them in great quality, but WordPress by default cut the quality to 90%. The whole idea of compressing images is here to help your pages load faster and keep file sizes smaller. Anyway if you still miss that extra 10% this is topic for you. Let me explain you a thing!

How to jailbreak any iOS 6 device, including iPhone 5
- Before you start, make sure you have a current backup of your iOS device. You can back up through iTunes or use iCloud. The choice is yours. This is a crucial step to ensure you don't lose important data should something go wrong and you have to restore.
- If you use a passcode on your iOS device, the evasi0n team suggests disabling it before you being the jailbreak process; apparently it can cause issues. You can disable your passcode in Settings > General > Passcode Lock.
Run the program. OS X users may have to bypass the Gatekeeper feature in OS X 10.8 by right-clicking the app icon and selecting "Open."
- Connect your iOS device to your computer, and click the Jailbreak button. Your device will light up, restart, and do all sorts of random things during the process. Just leave it plugged in and wait for the next instruction in the app window.
After a few minutes and a reboot or two, you'll be asked to unlock it and tap the "Jailbreak" icon. As the instructions say, only tap it once. Your iOS device screen will flash and then the evasi0n app on your computer will continue.
A few seconds later, you'll see a notification that the jailbreak has finished. While that may be true for the app, your iOS device will reboot a few times while the process finishes. You'll know it's truly finished when you see your lock screen and wallpaper. You should then have a Cydia icon on your home screen, confirming that the jailbreak was successful.
