Computer Continuously Restarts

If your computer continuously restarts while running, or if you see the flash of a blue screen before it reboot, then Windows is in a state where the only way it can attempt to fix itself is through rebooting. While this will work with the occasional system crash, it will not fix the issue if there is a drastic hardware or software problem. Instead, your machine will seem to be caught in a loop of starting up, crashing and rebooting. The key to solving this type of problem is capturing the crash message that is flashing on the screen.
Prevent Windows From Rebooting

You can stop Windows from rebooting after a crash by doing the following:

   1. Right-click My Computer
   2. Select properties
   3. Select the Advanced Tab
   4. Under Start-up and Recovery, uncheck the Automatic Restart box and then click OK.
   5. Reboot the computer

Now when your computer crashes, you should see the confusing Blue Screen of Death along with an error code. You can search Microsoft.com for the exact nature of that code and take measures to resolve it. Depending on the error, you might try rebooting into Safe Mode by tapping F8 while booting and running a System Restore to revert your computer back to a time when it was not crashing. Or you might run the error checking utility in Windows to scan your computer’s hard drive for issues. You might also run a popular program called Memtest86 to scan your computer’s RAM for errors that could be causing system stability issues.

The first step in this process is getting the blue screen to remain on the screen, and preventing the automatic restart is the way to do this. If you need more help in diagnosing your crashing computer please join our free computer

Printer Care and cleaning

The printer is very sensitive to damage if we can not take care of and cleaned properly and regularly. Here are some tips you can do to treat and clean the printer to be more durable.

A. Each cleaning the printer, make sure the printer is really in a state of death and no cables connected to either the electrical or computer.
B. Use non-flammable solution to clean on the printer.
C. To clean the head manually, you should use a clean soft cloth and do the scrub on the head slowly.
D. At a certain time, use the command "head cleaning" software contained on the properties of each printer to clean the printer head from the ink spread or spilled.
E. Use quality carbon ribbon, ink, or toner is good because it will affect the quality and age of the printer.
F. Do not ever make changes or modifications that do not conform to the printer as some parts of the printer contain high-voltage components.
G. Never put objects, such as iron, condensation, or food on the printer because if it falls into the printer, it will cause damage to some important components.

Troubleshooting on VGA

Ilustration: PCI Express

The following will discuss the indications of damage on the VGA and solutions.

A. There are not pictures on the screen because the screen connector is not installed on the VGA card or connectors are not installed properly.
Solution

• Make sure the connector is mounted display properly in the appropriate slot on the VGA card that is located behind the casing.

B. At the time the computer is turned on, a beep sounds good or sounds bid two times, but has not issued any image display on the screen. This is due to the installation or the VGA card does not fit properly in the PCI or AGP slot located on the motherboard or the VGA card that is used is broken.
Solution:

• Check your VGA card and attach it properly and fit in the slot corresponding with a VGA card that is used on the motherboard.
• Replace with a new VGA card.

C. Computer with a normal life, but there are letters on the screen flickering or lines appear due to the VGA card that is damaged.
Solution:

• Replace damaged VGA card with the new. Adjust with the use of computers.

Hopefully this article can be helpful and useful.

Borrows Google Packet Speeding Tech of New Linux kernel

Harnessing a pair of protocols developed by Google, the newly released version of Linux kernel should be able to speed network traffic throughput considerably.

The technique is one of a number of new features that come with the latest update of the open source operating system kernel, Linux version 2.6.35, which Linus Torvalds released on Sunday.

In addition the usual round of bug fixes and optimizations, the new version has a number of new features to make it more usable in today's bustling multicore, networked environments.

Chief among these new features is the inclusion of Google's Receive Packet Steering (RPS) and Receive Flow Steering (RFS). RPS spreads incoming packets out across all of the CPUs available on the machine, and RFS calculates which cores would be best suited for processing, given factors such as which applications will be using the network traffic, according to an explanation offered by the Kernel Newbies Web site.

The site cited a benchmark test showing how an eight-core Intel CPU-based server, with an Intel e1000e network adapter, doubled the number of networking-based transactions-per-second (tps) it could execute with RPS and RFS in place, from 104,000 tps (at about 30 percent CPU usage), to 303,000 tps (and 61 percent CPU usage).

The feature is a timely one, given the recent advances in network traffic protocols that allow for greater throughput. Ethernet vendors, for instance, are in the process of upgrading to the new standards for 40 Gigabit and 100 Gigabit Ethernet. "Network cards have improved the bandwidth to the point where it's hard for a single modern CPU to keep up," explained Kernel Newbies.

Other new features include a new form of memory compression, a front-end for a debugger supplied by SGI, the ability to manage multiple multicast route tables, and a new mode of the XFS file system that bundles logging tasks in order to cut down input/output traffic.

This new version of the Linux kernel comes less than the months after the release of the previous iteration, 2.6.34.
