My computer crashes frequently What is the reason The Lenovo V450 T6600 hardware I bought last year

There are several possibilities:

1.The computer is poisoned.

2.There is a problem with the operating system.

3.There is a problem with the hardware (unlikely).

Solution:1Thoroughly detect and kill viruses.

2.Reinstall the scanner system (so that it can also be completely disinfected).

If the above two do not solve the problem (which is unlikely), it is necessary to check the hardware.

1.Disassemble the chassis and remove dust.

2.Memory is reseated.

3.Turn on and run to see if the fan is working properly.

When does this happen?

If you don't have a lot of software running a lot of loads, such as large games, and you just browse the web and have a junior high school situation, it's a problem with the operating system.

If it is the former, it may be that the hardware configuration cannot keep up, then it is necessary to consider upgrading the hardware.

Let's see if your computer's hardware is broken. For example, the fan doesn't turn or something. It feels like the fan in your computer is broken.,Or there's a problem with the memory or something.。。

If the hardware is normal, try installing a different version of the system. Now it's better to use Windows XP

It's OK to install a system.

It's good to keep the half-year change system.

Please take a look and maybe there will be an answer.

Re-install the system manually, don't use ghost to install the system, if the problem still can't be solved, please send it to the repair service station again for testing.

Y450 is now almost the same as V450, Y450's graphics card 130M is much stronger than V450's 105M, 4800 can buy Y450.

It must be Y.,Y uses a 130M graphics card.。 V uses a 105M graphics card,**There is a lot of difference.。 Of course, Y is better, and I personally feel that Y is a little better.

The V450 is a business machine The Y450 is a student machine It can also be said to be an entertainment machine, and their** is about the same as the V450 that I saw in the mall** is a little more expensive than the Y450.

I bought the Y450 I just bought it, in fact, the configuration is almost the same, but the graphics card is different Y450 is better than V450 I feel that it is still Y450 good.

The configuration is almost the same, the graphics card is high, and the performance is of course higher. The performance of the small Y series is higher than all other series.

The Y450A-TSI** and V450 are similar, so if you want to play big games, choose the Y450.

It's definitely Y450-TSI, and the hard disk is 70G larger than the V450, and the graphics card is better than the V450.

The Y series graphics card is good, I think it's a wise choice to buy a better graphics card for a little more expensive money, buy a better one if you want to buy it, maybe you will need it in the future.

Disk suspension technology can terminate the read and write operations of the hard disk when it detects the rapid movement of the computer. to protect the hard disk.

The temperature of your machine is a bit high, it is recommended to buy a cooling base. However, this temperature of the V450 is relatively normal!

It is best to clean the air outlet every six months.

That's a high temperature in a V450.

The keyboard is also IBM's technology.

The Y450 is still better, first of all, its graphics card model is good; Also, this machine should have better workmanship and a bit better quality than the V450.

V's screen is positive and looks a little more comfortable.

Of course, it's Y450, the new version of the 240GTGPU, the market price is about 5100, which is cheaper than ASUS with the same configuration, Dell does not have a model with the same configuration as Y450, but when it comes to workmanship, Y450 is indeed unsatisfactory.

My machine is worse than yours, so it's not stressful to deal with CAD.

If your machine is used for 3D modeling and design, your graphics card is the main bottleneck.

Low-end 64-bit graphics card, powerless 3D!!

Changing the CPU is also not recommended, it doesn't help much!

Since the graphics card BGA is on the motherboard, professional equipment is required to replace it, and the chip + maintenance cost is no longer few.

Therefore, it is not recommended to change the processor and graphics card.

What I want to say is that your system should not use win7, this system will eat up your memory at least.

How much memory do you have left for data exchange when designing and modeling?

There are two options here:

1. Change the XP system, don't think about adding memory!

2. Change win7 64-bit + 64-bit ACAD + memory reference memory.

Samsung Gold Bar DDR3 1066 2G Notebook RAM 89

Kingston DDR3 1066 2G Notebook RAM 109

Do a systematic way to give you a reference.

If you have any questions, please hi or follow-up!

Hope it helps!

The landlord's book belongs to the low configuration, and the so-called low, mainly low in the graphics card (especially for 3D production, 3D games).

That is to say, the building mainly has a significant acceleration upgrade, which is to upgrade the graphics card (other replacements will not increase the 3D running capacity of the computer. ）。

And the graphics card of the notebook,It is difficult to find a matching graphics card to replace (size、thickness、Power supply and other factors),Even if you can find it,The replacement cost will be very high。。。

So finally able to give advice to the landlord:

Make do with it, and don't waste money on that notebook again.

When the budget is sufficient, buy a high-end graphics card (but I suggest that if you really do 3D production, you should still use a desktop), because the laptop graphics card will work less frequently due to heat dissipation problems, etc.

You use the hardware master to take a screenshot of the hardware description and look at it, the diagram you sent is not a configuration diagram. Mainly graphics card · Memory· And the processor is important, you want to upgrade these items, but you also need the motherboard to support.

1. If you want to upgrade the hardware, you can generally change the hard disk and install the SSD; If the memory is not large enough, you can add a memory module; The rest is not cost-effective.

2、It's a change of system, win10 system is not bad,Boot、The processing speed is quite fast。

What can be upgraded is nothing more than the CPU, memory and hard disk, CAD mainly tests the CPU and memory, your CPU is passable, the memory should be enough, and if the performance is not good, it is more important to check what is installed in the system.

Lenovo launched two practical business booksV350**Higher than V450,Because V350There are more functions,The most distinctive thing is that he has the function of preventing hard disk data loss,That is, when you tilt the notebook,If there is a problem when the hard disk reads the data,V350The anti-hard disk data loss function will work,Automatically help you turn off the computer。 It is a very practical notebook, with a very high performance and excellent configuration, and good stability.

Seriously, I really want to recommend the Y450.

V450 is recommended, the graphics card doesn't seem to have to be replaced, soldered.

If you buy a notebook, you generally won't change parts.

The graphics card is not exchangeable and is fixed to death. However, mainstream single-player games are still fine, as long as you don't play large-scale games like those in Europe and the United States, such as Call of Duty and Assassin's Creed.

However, the V350 for men is not atmospheric enough, and the V450 is actually very suitable.

V350The heat dissipation effect is not good,Originally13Inch heat dissipation is worse than 14 inches,And you are still game-oriented,Although the graphics card is the same,But it's definitely not as good as V450。

I just like the appearance of the V350 T6600, 13 inches, and it is very comfortable to carry as if there is no back.

Dual graphics card switching,Online games can be played in general,Like Warcraft,QQ Speed, etc. can be played, I bought it left and right,5600+330,It's 330 including headphones,Mouse,Bag,Lock,Pad,Screen film,Keyboard film。

I've been using it for almost 3 months, and there is no problem for the time being.
