Grains PC Upgrades
PC Upgrade
Most computers can be upgraded, In most cases a faster CPU and extra memory can be fitted.
Hard Drives can be replaced with a larger unit, or alternatively you can add an extra drive to your machine as a backup drive.
The power supply may need to be upgraded if you fit a different motherboard and CPU. An extra drive can sometimes mean you have to upgrade the PSU also.
Hard disk drives can be replaced with larger and faster drives. CD/ROM drives can be replaced with CD or DVD writers.
Memory Upgrades
Fitting extra memory can increase a PCs performance. A few simple rules should be adhered too.
Where possible do not mix and match memory as miss matched memory modules can in some instances actually reduce performance. Where two or more modules are fitted they should be the same make and size to ensure best performance from the upgrade.
Processor Upgrades
If a Processor is still available for your motherboard,, then you can upgrade the CPU. This will give you quite a good performance boost especially if you have already upgraded the Memory.
Celeron and Duron processors can be changed for Pentium and Athlon processors.
Hard Drives
If you need more space to store your files, the hard drive can be changed for a larger unit. If performance is your main concern then the OS hard drive should be changed for a unit with a faster rotational speed i.e. RPM.
Drives used to be rather slow in comparison to today's hard drives. 5000 RPM or slower used to be the norm. Today's hard drives can run at 5000, 7200, or 10000 RPM.
Faster Revolutions per minute results in faster access times which give faster PC response times. Try changing your old tired 5000 RPM drive for a 7200 or 10000 RPM drive. You will notice a slight increase in PC performance.
Power Supplies
Power supplies also need to be upgraded if you are running more than the standard amount of drives. Before considering an extra hard drive and or CD/ROM check the power supply wattage.
To be able to fit 1 extra hard drive you should have at least a 300 or 350 Watt power supply.
Make sure the power supply fitted is capable of supporting the extra drives, and any new board and processor fitted.
When a power supply breaks down it can be quite dramatic. If you are near the machine at the time you may hear a sharp popping sound or a bang. In most cases changing the power supply resolves the problem and your machine will boot and run normally.
Occasionally, however, you may not be so lucky. Power supply failure can seriously damage all your hardware so is best avoided.
Sometimes you can change the power supply and all will be well. If you are unlucky, you will find that the hard drive CD/ROM and motherboard and possibly other components have been damaged by the voltage spikes created by the failing PSU.
The Power supply is often overlooked when upgrading a computer. Failing to upgrade your power supply can seriously damage your new PCs health.
Possibly as high as 1 in 3 PSU failures result in motherboard and or other hardware damage.
