Are you Computer Keeps Freezing?

The way to stop your computer from freezing is to fix the problems that are causing it to crash & freeze in the first place. Windows does not freeze willingly, and the problem is mainly caused by your system having a fault or damaged setting that your PC is unable to process.

The first thing you should do to fix this problem is to reboot your computer into "safe mode". This is done by restarting your PC and pressing F8 continuously to load up an options screen. On this screen, select the "Safe Mode" option which will open Windows without any of the drivers or software that can damage it. Doing this will allow your computer to load up without any of the software that could be causing it to freeze... meaning that if it does not crash in safe mode, then the software of your PC is to blame. If your system does crash in safe mode, then it's likely going to be a hardware issue which should be looked at by a computer technician.

If you run your PC in safe mode and it does not crash, then you've likely got a problem with the software on your computer. This is actually quite easy to solve thanks to the nature of this problem. Most of the time, Windows systems freeze or crash because they cannot process the files & settings that they need inside the registry. The registry is the database which stores all the settings and information for your computer, and is where Windows keeps everything from your latest emails to your desktop icons.

The registry is a highly important part of Windows, but it's also one of the main causes of your system crashing. The problem is that since Windows needs to read 100's of settings from the registry each time you use your system, any damaged or corrupted settings that are inside your PC will actually make Windows run slower as it has to take longer to read these files. However, if the settings become so corrupted that Windows cannot read them at all, it has no choice but to freeze and crash. This is a very common problem and is very simple to fix.

To fix a computer that crashes because of software issues, you should first download a registry repair tool. This is a software tool which scans through your system and fixes the files that could be causing it to crash. These tools are very efficient and if you can get one which works well to fix the largest number of problems on your system, it will make your PC a lot more reliable and should stop all the freezes.

How to force uninstall System Security Antivirus From Your Computer

What is System Security Antivirus? 

System security Antivirus is a rogue anti-spyware application. At first glance, System Security Antivirus looks like a normal anti-spyware remover. Nevertheless, this application was designed to trick the user into purchasing a full version of System Security Antivirus. In order to succeed, the rogue uses well known scaring and money stealing tactis. Also, System Security Antivirus is probably a clone of other rogue applications.

Once PC is infected, System Security Antivirus performs fake system scan and reports various bogus results and  fallacious alert messages  stating that computer has serious security problems. In order to remove these imaginary threats and protect the system from future attacks, user is advertised to purchase a full version of System Security Antivirus.  However, it's a scam. A full version of Renus2008 doesn't even exist. Instead of buying this worthless application, remove it from the system immediately after firts appearance.

How to remove System Security Antivirus?

1 The first thing you need to do to remove this program from your PC is to get a trustworthy anti-spyware / anti-malware and then let it scan your system. Many people make the mistake of just trying to delete the files or settings this software installs onto your system, but the fact is that it has a number of different elements which will just it to come back. You need to use the likes of MalwareBytes (free) or SpywareDoctor (paid) to get the roots of this problem.

2 You should also clean out the 'registry' to make sure that there are no settings or files that this virus has left in there. Not many people know about this part of your system, but the fact is that this infection will leave 100's of infected registry settings on your system, ready for any other viruses to come along. The registry is a large database inside Windows which keeps all the settings and files that your computer requires each day to run - it's like a big library of vital information for your system. To clean out all the damaged parts of this database, you need to be able to use a 'registry cleaner' to scan through it and fix the errors that are inside.

Intel: 2-year-old Nvidia GPU bests 3.2GHz Core i7

Intel researchers have published the results of a performance comparison between their latest quad-core Core i7 processor and a two-year-old Nvidia graphics card, and found that the Intel processor can't match the graphics chip's parallel processing performance.

On average, the Nvidia GeForce GTX 280 -- released in June 2008 -- was 2.5 times faster than the Intel 3.2GHz Core i7 960 processor, and more than 14 times faster under certain circumstances, the Intel researchers reported in the paper, called "Debunking the 100x GPU vs. CPU myth: An evaluation of throughput computing on CPU and GPU."

In a bid to discredit claims that GPUs outperform Intel's processors by a factor of 100, researchers compared the performance of the quad-core Core i7 processor with the Nvidia GPU running a set of 14 throughput computing kernels. The comparison was designed to test the parallel processing capabilities of the chips.

As its name suggests, parallel processing involves tackling multiple tasks simultaneously as opposed to serial processing, which requires handling tasks in sequential order.

Graphics chips, with dozens of cores that are used to draw polygons and map textures used to create realistic images on a computer screen, are well-adapted to parallel processing tasks while processors with fewer, more powerful cores, like the Core i7, are better suited for serial processing applications. That's not to say that quad-core chips like the Core i7 can't handle parallel processing tasks; they can, just not as well as GPUs like the GTX280, as the Intel study confirmed.

"It's a rare day in the world of technology when a company you compete with stands up at an important conference and declares that your technology is only up to 14 times faster than theirs," wrote Andy Keane, Nvidia's general manager of GPU computing, on the company's blog, which provided a link to the Intel paper.

Even so, Keane wasn't impressed by the performance margin reported by Intel, listing 10 Nvidia customers that saw application performance improve by a factor of 100 or more by optimizing them to run on GPUs. The performance comparison done by Intel likely did not include the software optimization required to get the best performance from the GPU, he said, noting that Intel didn't provide details of the software code used in the comparison.

"It wouldn't be the first time the industry has seen Intel using these types of claims with benchmarks," he wrote, providing a link to the U.S. Federal Trade Commission antitrust suit filed against Intel in 2009.

In that suit, the FTC alleged previous benchmark results reported by Intel "were not accurate or realistic measures of typical computer usage or performance, because they did not simulate 'real world' conditions."

Regardless of the exact performance difference between CPUs and GPUs, graphics chips are an increasingly common feature in high-performance computing systems, including extremely powerful computers like China's Nebulae system. Nebulae, which is currently the world's second most powerful computer, is powered by a combination of Xeon server chips and Nvidia GPUs.

Adding GPUs to a system can substantially increases performance, while reducing cost and power consumption compared to systems built using only CPUs, said Yury Drozdov, CEO of Singapore-based server maker Novatte.

Last year, Novatte built a system for a financial customer that wanted to run pricing models. The system, which cost more than $1 million, used 60 Intel Xeon processors and 120 Nvidia GPUs. A system with similar performance built using Xeon processors alone would cost $1.6 million and consume nearly 28% more power, making it more costly to operate than the system built with GPUs, Drozdov said.

For its part, Intel recognizes the importance of having a powerful parallel processing chip in its product lineup to complement its CPU line. In May, Intel announced the development of a 50-core chip called Knights Corner, which the company hopes will fend off competition from graphics chip makers in the high-performance computing space. Intel has not said when Knights Corner will be available.

By comparison, Nvidia's GTX280 has the equivalent of 30 processor cores, while the company's recently announced Tesla M20 series GPUs have 56 cores.
