Prawns for help! Host Upgrade! Urgent!

The computer is too old, and the performance is not high after upgrading, which is a waste of money. For example, if you change the CPU of the graphics card and the CPU is not strong enough, you may have to change the motherboard, and the old memory will not be used after the new motherboard, and you will have to change the CPU motherboard of the graphics card, and you will have to change to a power supply with a higher power.

Chain reaction), basically only hard disks, optical drives can not be replaced, so it is better to change to a new machine. If you have less money right now, it's a good idea to save when you have enough money and then go on a big shot. The old computer taught my dad how to type. Huh

If you only have that much budget, then option 2. If the budget can be increased, then dispose of the 7300GT as well, although it is better than the onboard 3200, but it is also very low-end. Change to a graphics card of about 400 500 yuan.

Sapphire HD4650 platinum version 499 yuan. A little better on the sapphire hd4830 platinum version of 699 yuan. The motherboard uses Gigabyte GA-MA78GM-S2HP 599 yuan.

The landlord is really painstaking, but the upgrade of a set of configurations needs to be balanced in all aspects, not as simple as adding a memory, for the 8650 processor and motherboard, both of which add up to 1000 yuan, sell your processor and motherboard, can you sell it for 100 yuan? The processor and motherboard have been replaced,The power supply must be changed,The rated 220W can't be brought up,This adds another 200 yuan,DDR 400The memory also needs to be replaced,Add another 150 yuan,The previous memory can be sold for 50 yuan,How can it exceed your budget,And it doesn't make much sense,Your current configuration is no problem to play a CS,If you want to play mainstream large-scale games, you have to at least 96GTThe level of the independent display,Otherwise, it doesn't make much sense,The landlord thinks about it again。

I had no hesitation in choosing option 1

This is the best value for money! It is also the highest utilization rate of old things!

Don't use ASUS motherboards, GIGABYTE G45...

First of all, see if it is caused by the resolution setting problem, press the F8 button when you boot up, and the advanced options menu will appear in the release of your hand, and select to enter the "VGA mode" to enter the system. After logging in: Right-click on the desktop to select Properties Settings Advanced Adapter List all modes Drag the scroll bar up and down, and click to select "1024*768, True Color (32-bit), 75 Hz, LCD Select 60 Hz", click "OK", click "Apply" OK, and finally restart the computer (or set the appropriate resolution by yourself).

If the above method is not possible, discharge the BIOS battery (restore the BIOS factory default), it is recommended to plug and unplug the graphics card and memory, clean up the hygiene, and polish the gold finger of the graphics card and memory (if you can't solve it, you can overhaul it).

How to troubleshoot the failure of the computer without display when it is turned on (check whether there is a bulging capacitor).

Step 1: First of all, check whether the external wiring of the computer is connected, and plug in each cable again to see if the fault is eliminated.

Step 2: If the fault persists, then open the main chassis to check whether there is any excess metal in the chassis, or a short circuit caused by the deformation of the motherboard, and smell whether there is a burning paste in the chassis, whether there are burned chips on the motherboard, and whether the capacitors around the CPU are damaged.

Step 3: If not, then clean the dust off the motherboard and check if the computer is in good condition.

Step 4: If the fault persists, unplug the reset cable on the motherboard and connect it with other switches and indicator lights, and then use the change cone short-circuit switch to see if it can turn on.

Step 5: If you can't turn on the computer, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device.

Step 6: If the fault persists, the fault may be caused by devices such as memory, graphics card, CPU, motherboard, etc. Then, use the plug-in method, swap method and other methods to check whether the memory, graphics card, CPU and other devices are normal, and replace the damaged devices if there are damaged devices.

Step 7: If the memory, graphics card, CPU and other devices are normal, then discharge the BIOS, use the isolation method, place the motherboard outside the chassis, connect the memory, graphics card, CPU, etc. for testing, if the computer can be displayed, then install the motherboard into the chassis for testing until the cause of the fault is found. If the fault persists, you need to return the motherboard to the manufacturer for repair.

Step 8: When the computer is turned on without display but there is an alarm sound, when the computer is booted up, the system BIOS starts to POST (power-on self-test), when it detects a fatal error in a device in the computer, it will control the speaker to send out a sound to report the error. Therefore, there may be a fault that the power is turned on without displaying an alarm sound.

If the computer is turned on and there is no alarm sound, the fault can be checked according to the meaning of the BIOS alarm sound to check the faulty device to eliminate the fault.

Unplug the power supply.

Press the power switch a few times.

Drain static electricity.
