HOW ABOUT DELL M511R 628 THIS COMPUTER

I'm using M511R-628 dual graphics card hybrid firefire technology to improve graphics card performance by 50% 8G memory (upgrade by yourself) AMD A4 CPU automatic overclocking CPU can reach more than 3G It feels very good World of Warcraft or something is no problem to run It belongs to the high-end computer in the online test and is among the best, the graphics card gives me some points But the actual use is a dual graphics card work So the actual use effect is not said, and I advise those students who don't understand computers, Intel is not necessarily better than AMD A series. If AMD didn't have its own unique skills, how did it survive until now, it would have been squeezed by Intel and paved the way it was, you see Intel has a hybrid crossfire APU How does 3D compare with AMD.

There are 2 benefits to Dell's AMD machines, one is that it is very cost-effective! Intel models with the same configuration as the 511R are much more expensive. 2 is AMD certified and specifically optimized, so there is no such thing as being worse than Intel.

Yes, buy and live** don't buy and sell well.

What is the main purpose of your computer? The more mainstream machines are New14R and New15R. Intel's second-generation processor, 500G hard disk, 1G independent display, the configuration is still very powerful.

Click on the link in the lower right corner of my answer to enter the platform, and I will help you analyze the configuration in detail. I'm doing the event right now, so I'll send it to you.

It's okay, but the after-sales service is not very convenient.

Hello, please provide your phone call to bury your brother service code for further verification of your model. The service code of the notebook model is located on a long strip label at the bottom of the fuselage, which consists of 7 digits of English + numbers; A small number of XPS models need to cut out the nameplate at the bottom; The desktop multi-carrier chain is located near the backrest of the chassis.

Hello, this situation is generally due to the installation of some domestic optimization software for "optimization" or "junk cleaning", resulting in the driver of the network card being disabled or lost. Disturbing Zen.

You just need to uninstall the optimization software, reinstall the driver of the network card once, and the problem will be solved.

If it is an early wireless network card, and it still can't be solved after pressing the above operation, you can try the following methods:

1. Device Manager, right-click on the wireless network card - Properties, and change the default to 20 40 MHz.

2. Open the Network and Sharing Center - Top Left Corner - Manage Wireless Network, pop up the relevant icon, and right-click the previous wireless network - Delete Network.

3. After deleting, reconnect to the wireless router, enter the user name and password, and then pop up the window, be sure to select the public network.

1. Use disk cleanup to clear the system junk files.

2. Start --- running--- enter msconfig and uncheck all the unnecessary enablement items (such as msn qq, thunderbolt, emulet, virtual optical drive, etc.).

3. Detect and kill viruses and malware. Turn off real-time monitoring and keep your virus database updated and disinfect regularly.

4. Check whether the heat dissipation vent is clean.

5. Whether the ambient temperature is too high.

6. You can consider buying a *** heat dissipation bracket to help the laptop dissipate heat.

7. Close some useless running programs to reduce the burden on the fan.

8. Back up your data and reinstall the operating system.

9. If it still doesn't work, it's best to go to the after-sales department to clean up the dust.
