Tip 1: How to upgrade your computer
Tip 1: How to upgrade your computer
Any equipment with the passage of time becomes obsolete,especially with regard to computer technology. Over time, there are more and more advanced operating systems and applications that require more and more calculations and operations with which the old hardware can not cope.
You will need
- - program for collecting information about the computer;
- - necessary accessories
Instructions
1
To get started, find out all the parameters of your own Computerto learn about the possibility upgrade. If the system is older than 5 years, then about anyimprovements can be forgotten. In this case, the upgrade will be equivalent to buying a new computer and all its components. Install the program Everest, which will collect all information about the computer and specify the characteristics of the entire system, from which you will need to buy new hardware. You can use an easier, albeit less functional CPU-Z program.
2
Most often, the most importantparts of the computer - processor, RAM, video card, hard disk, motherboard. Please note that after replacing the processor or video card, you will most likely have to buy a new power supply that will ensure the stable operation of the computer with new, more demanding components.
3
When choosing a new processor, make sure that its Socket number and the manufacturer's name match the same value on the motherboard.
4
If there are empty slots on the motherboard for the RAM slots, then it will be advisable simply to buy new modules and install them.
5
To run all modern 3D games andgraphics applications often have to change the video card, which should also be chosen based on the architectural features of the motherboard. On some cards, there are two video card slots that can be programmed into a single system (in the case of Nvidia this is called SLI).
Tip 2: The most common user errors when building, upgrading, or maintaining a computer
To assemble the system unit of the computer, connect toThe periphery is simple enough, because when designing, it was taken into account that the components of the PC users can install (buy, change during the upgrade) themselves. But nevertheless, a sufficiently large number of users allow almost childish errors in this process.
From personal experience, I would like to highlight such types of errors:
- wrong choice of accessories.
To upgrade PC users can purchaseRAM, processor, memory slots, hard drive, etc., not suitable for the existing platform. It is known that the motherboard supports only certain types of devices, but users can forget about this and, for example, purchase the DDR3 card instead of the DDR2 RAM. With the naked eye, you can see that these bars are even geometrically different, but the most stubborn users can forcefully push a new bar into the slot, which will cause an irreversible malfunction of the PC.
Conclusion: if you want to buy RAM, buy morea powerful processor or video card, a hard disk of a larger size, make sure to specify the model of the motherboard before purchasing. This can be done in documents to a PC or a special program.
- Incorrect connection of peripheral devices.
Connectors for connecting a monitor, printer,scanner, keyboard and mouse, other devices are asymmetric so that the user can connect the device only correctly, but there are cases when the owner of the PC forcefully pushes the plug into the connector by the other side or at all chooses a socket that is not, in principle, intended for this plug .
Helpful advice: remember that any cable should not be driven into the connector with force!
- Improper maintenance.
Nastitavshih useful articles about cleaning the dust, shiftthermal grease, the need for other computer maintenance, some users are too zealous for the matter. Perhaps that's why system administrators are faced with broken keys, user-deleted system files (without which the OS does not start) and other problems that the user created himself.
Helpful advice: if you do not know the basics of electrical engineering or althoughwould not understand the laws stated in the school textbook of physics in the section "Electricity", as well as the text in the textbook of informatics, if you were asked to sit in the laboratory on physics and just see how the comrades work, do not follow the advice found on the Internet (especially, that, unfortunately, today some articles are written by inexperienced system administrators who try to retell the information found on the Internet on this topic).
Tip 3: How to make an amplifier for a sub
The presence of two active audio-columns is an inalienablepart of a modern multimedia personal computer. They can be fixed on the monitor or installed next to it. But due to some physical limitations from such speakers, you can not achieve normal reproduction of the full range of sound frequencies. Particularly affected in this case are low frequencies.
Instructions
1
Choose the material for making boxes forsubwoofer. If you intend to make a subwoofer in your car, then for convenience, make a box trapezoidal shape and with a beveled back cover. To make a box is better from the chipboard thickness of approximately 16 mm (not too thick, and will not allow to rattle), along the perimeter of the box, fit wooden bars 25x25 mm, twist all the screws in wood.
2
Then thoroughly glue the PVA (more expensiveor more durable glue here to use there is no sense). For easier operation (if you have to often carry a sub), you can drown the side walls in the case a little or adjust additional handles for transferring (again, depending on how big the sub is).
3
In the left side panel, make a hole in the200x120 mm, if you want to make an active subwoofer, insert a plate into the hole, to which subsequently fix the radiator with amplifier board, power connectors, input connectors, for connecting the remote amplifier switch, for the LED, the power indicator and the H-Mode. You can also take out the fuses. Securely secure the panel to the cabinet with screws.
4
Glue the box from the inside with any soundproofing material (polyurethane, cotton wool, however, that will fall under your arm, the main thing is to work). From above you can glue the box with a carpet or other strong material.
5
Make amplifier on the resulted microcircuit (works on 2 Ohm). However, in the process, something can be discarded in favor of the design, depending on the source material.
6
As a result, you will get pretty gooda subwoofer that will give out a deep and pleasant bass, creating for all good sound pressure. Not the limit of dreams and perfection, but for a normal music lover is a good device.
Tip 4: How to know the type of your RAM
When upgrading your computer, many users ask questions: "What memory is on my computer? Which a type memory? What is the frequency? ", Etc. These important questions, or rather answers to these questions, will help to properly upgrade your personal computer.
Instructions
1
There are many ways and programs to help you check which memory you have installed. You can simply open the cover of the system unit, and check the information written on the slats memory. Also you can visually check a type memory DDR / DDR2 / DDR3 and speed modules memory. If you decide to do an upgrade, this information will be very important to you. At the same time you will see what kind of motherboard you have, and you will be able to find information about it.
2
You can also find a guide to the motherboard, or at least a warranty card. In these papers you can also find information about the modules memory. In the manual for the motherboard, you can find out what are the limitations on the volume memory exist at the motherboard.
3
If the first two methods did not help you, or you did notfound a guide to the motherboard, and the open case is not qualified, then you can use special software. There are a lot of these programs. There are free small programs that are designed specifically for working with memory. But such software packages, as a rule, are very expensive and cumbersome. Most users will only interfere with them, than help.
4
Consider the program cpuz. It can be downloaded from the Internet. It is free, weighs very little, does not require installation. It can be run from any flash drive, or floppy, i.e. from any external device.
5
All you have to do is just clickdouble-click on the program icon and wait a few seconds for the program to read all the necessary information. Upon completion of the work, it will provide information about the motherboard and modules memory. If you need information about the BIOS, the microprocessor, etc., then this program will also help you with this.
Tip 5: Than so good mac os
One of the popular operating systems,competing with Windows, is an exclusive system of Mac OS. The brainchild of the notorious Apple every year is gaining more and more liking for users.
