Will Re-Installing Windows Take Care Of A Slow Computer?

Will Re-Installing Windows Take Care Of A Slow Computer?

If you’ve ever suffered through the re-installation of your operating system, you know (or at least you should know) that reinstalling the operating system is a last-ditch effort to correct an intractable problem. Unfortunately, a lot of users (and technicians alike) use it as a cure-all when basic troubleshooting and maintenance don’t resolve a slow computer problem.

Is Reinstallation Necessary?

Reinstallation may have been necessary – even preferred – at one time to take care of slow computer problems. In my view, it’s akin to pulling out the biggest hammer in the toolbox. I tend to avoid re-installation until I’ve exhausted all other options. I do this partially because there are a lot of settings and adjustments I’ve made to my personal computer that I simply don’t want to lose.

There is also the issue that once a fresh installation of the operating system has been carried out, you may find yourself spending an additional hour (or hours) applying every patch and service pack that’s been issued since the new OS was introduced. If your version of the OS is new, this can be relatively painless. If not, you could be applying 40-60 patches and one or more service packs to your “fresh” installation. And you also run the risk that after completing this Herculean task, you’ll still be left with a slow computer.

A better approach is to determine why the computer is behaving slowly in the first place. Computers can slow down for a variety of reasons – including lack of physical memory, lack of available disk space, and significant fragmentation on the hard disk. You could also experience problems with device drivers that have begun to misbehave. There’s also the odd possibility that a recent OS update or patch isn’t performing as expected.

Once you’ve determined that your computer has sufficient resources to run the applications you use, you can also check the network connection and the servers you’re connecting to. If your computer operates normally with its network card disabled, your problem isn’t likely to be solved by replacing the OS.

People tend to ascribe odd computer behavior to viral infections. While it’s true that viruses can certainly slow down your computer and decrease its ability to perform, a good anti-virus program will not only detect and remove offending malware, it will also prevent your computer from being impacted in the first place.

I advise people to download a registry cleaner like SpeedUpMyPC because it not only manages the registry, it also optimizes the computer for the best possible performance. If you’re not impressed with your computer’s performance, download a copy of SpeedUpMyPC and see for yourself why more than a million PC users rely on it to speed up their computer performance.

New Slow DOS Attack Could Cripple Computer

New Slow DOS Attack Could Cripple Computer

New Slow DOS Attack Could Cripple Computer

One of the researchers at Qualsys Labs has created a proof-of-concept denial-of-service (DOS) attack that, in theory, could turn a speedy server into a slow computer virtually undetected. How? Simply by changing the way a server must respond to an incoming packet of information.

Slow DOS Attack Concept Not New

The idea of attacking a Web server one piece at a time isn’t new. In 2009, Slowloris demonstrated the “death-by-a-thousand-HTTP-requests” approach, in which partial page requests are dribbled out in a maddeningly slow fashion. After awhile, Slowloris can clog up most or all available TCP ports, effectively stopping the server in its tracks.

The latest evolution of the slow death takes a different approach. Instead of issuing partial requests, Slow Read issues full page requests but then slows down the server by reading the response ever so slowly. In addition, the attack could exploit the variable TCP packet size to create zillions of exceedingly tiny packets, which are then read oh-so-slowly. The server, which is ready to send data, must hold unread packets in a buffer, waiting for the attacker to request more data. If a number of malefactors applied this to the same server, the server would simply stop working for legitimate users as it waited to ship little, tiny data packets to the slow readers of the world.

The result: one seriously slow computer. What is the likelihood that the Internet will suddenly screech to a halt with this? Not much. Server admins can prevent this kind of attack by configuring Web servers (or any server – really – that uses TCP/IP) to refuse connections to requestors that set unreasonably small data packet sizes. They could also address the issue by timing out requests. If a page request can’t be completed (on the recipient’s side) within a certain reasonable period of time, the connection could be (and should be) dropped.

The theoretical attack, however, does underscore the role of data transmission in computer performance. Sometimes computers that are connected to a network are exceedingly slow – not because something’s wrong with them – but because something’s wrong with the computer on the other end of the connection.

That’s always something to take into consideration when trying to troubleshoot a computer problem. If the problem occurs during a network connection, disconnect the computer from the network. If performance improves, you know that the problem is related to the network connection and not to the computer in question.
