Why to Upgrade?\r\nEvery new software development released, the Hardware requirements increased like new Microsoft Windows versions, new graphical editor application programs, Games .... Etc, plus when you upgrade you get almost a new PC with a very low cost comparing with a new one.\r\nHow to take precautions before the upgrading?\r\nBefore upgrading your computer you have to take some points in consideration:\r\n\r\n\tFirst of all think about for which purpose you want to upgrade? For instance if you want to upgrade to speed up your PC you have to think for upgrading the RAM and\/or the CPU, if you want to upgrade for playing a new 3D game you go for upgrading the VGA card \u2026 etc, so if you use your computer only for surfing the Internet, chatting or writing documents no need to make any upgrades which will show no difference to your work.\r\n\tThink about Hardware compatibility, i.e. to purchase a RAM you have to check whether it is compatible with your Motherboard in terms of slot type (which tells you either the RAM is SDR, DDR1 , DDR2 or DDR3), plus the data bus speed (should be compatible with your motherboard, refer to your motherboard user guide for more information).\r\n\tCheck whether there is a free space or slot to add the new hardware (in case if you want to add a new one not to replace the old one), i.e. if you want to purchase new Hard Disk to add it into your PC case, check if there is enough space where you can install it, also check if there is a free IDE\/SATA cables, power cables to be connected to it.\r\n\r\n Note: Before upgrading, always be sure to wear the anti static charge strap in order not to spoil any peripheral you touch by accident and in case you don\u2019t have this strap or you couldn\u2019t find it try to touch the PC case power supply body while operating before starting the upgrading process to discharge any possible static charge on your body. \r\nTips for performing the Upgrade\r\nUpgrading the RAM (Random Access Memory)\r\n\r\n\tCheck first what type of RAM your motherboard support.\r\n\tCheck whether there is a free slot for installing the new RAM.\r\n\tIn case you have more than one free slot, and you want to upgrade for 2GB RAM, try to purchase one RAM of this size instead of purchasing two for each 1GB, this would decrease the total price + you gain better performance.\r\n\r\nUpgrading the CPU (Central Processing Unit)\r\n\r\n\tCheck your Motherboard bus speed to check for compatible CPU (refer to your Motherboard user guide).\r\n\tCheck your Motherboard Processor slot type with the old one (prior the purchasing).\r\n\tInstall the CPU fan and connect its power cable to the mother board.\r\n\r\nUpgrading the Hard Disk\r\n\r\n\tCheck whether there is a free space inside the PC case to install the new Hard Disk.\r\n\tCheck the compatibility of the cable and power types which will be connected to the Hard Disk.\r\n\tCheck the settings of the jumper on the back of the Hard Disk which should be the same as the old one according to the connection method.\r\n\r\nUpgrading the VGA card\r\n\r\n\tCheck what type of slot do you have on your motherboard for VGA cards? PCI, PCI express or AGP slot? Accordingly the type of the VGA card should be compatible.\r\n\tIn case if your motherboard has a built in VGA card you have to disable it from the BIOS setup menu after installing the new VGA card.\r\n\tReboot and install the Hardware driver on your Windows.\r\n\r\nUpgrading the Sound card\r\n\r\n\tCheck whether your motherboard has a free PCI slot (in case if you where using the built in sound card).\r\n\tReboot and install the Hardware driver on your Windows.\r\n\r\nUpgrading the Motherboard (Main board)\r\n\r\n\tCheck your PC case size which should fits the motherboard size.\r\n\tCheck the old peripherals slot types where all the old cards and peripherals should be compatible with the new Motherboard.\r\n\tAfter installing the new one install all the PCI and VGA peripherals and connect all the cables (power \/ data cables).\r\n\tReboot and edit your BIOS settings if required by pressing F8 while rebooting.\r\n\r\nUpgrading the Power Supply\r\n\r\n\tYou might also need to upgrade your Power Supply if after several upgrades your computer power consumption increased, so learn more about Power Suppliers.\r\n\r\n You might also want to read about "How to find the best PC and purchase it?"
