Run a virus scan. McAfee & Norton's are two of the most popular anti-virus programs. Hope this helps.

I think a virus running real slow


Hello,

If it's in the internet browser only and not the whole computer, then try using a different website browser like Google Chrome, Mozilla Firefox or Safari.

If the whole computer is slowing down, then run a full anti-virus scan. If no viruses are found, then do a disc clean up. GO to start > Programs > Accessories > System Tools > Disc Clean up

Delete all unneccessary files. Just put a check mark on all. After that, restart your computer. Install or update the device drivers - You can use RadarSync to update them all so that you won't miss any outdated driver in the computer.

I hope this helps!

If you have any questions, please drop me a line.

Computer faster guide


Computer slow is really a headache to users. Therefore, people always ask question about how to get a slow comouter faster. For that, you must firstly know why computer slowdown. After diagnosing the problem, you can fix slow computer more easy.

Here we gives you some advice to make your PC faster.

The most possible causes of slow problem for an old computer.
1 Corrupt registry is the number one cause. In short, the registry is the fort of the system. The most important date and setting are restored in the registry. External change may damage the key and make it mess up. In that case, you may face a blocked Windows. Visit here to cleanup registry and speed computer.

2 Discontinuous harddisk is know as the NO.2 reason. I would not talk about too much. Here just show you how to defrag a slow computer.

  1. Open My Computer.
  2. Right-click the local disk volume that you want to defragment, and then click Properties.
  3. On the Tools tab, click Defragment Now.
  4. Click Defragment.
3 What you should notice is that old computer may lack of RAM. The machine configuration never keep up with the computer development. Now the basic requirement is 1 GB.

Why a brand new computer is slow?
1 I think you forget to update the anti-virus. When merchant install system for your, they also install antivirus program for you. However, the anti-virus is not updated to latest virus database.

2 Sometimes, it is Windows fault. You have to update SP2 to SP3. Suggest you download all microsoft patches.

Why does my Dell Optiplex GX620 Randomly lag? the whole system will lag like the mouse and sound and how can i fix it?


Computers do slow down with age, not becuase the hardware is worn out but becuase the OS gets slow. Not sure why.

You could try a clean install of your operating system, that always works. If you still have a problem then you know its your hardware.

Before you proceed with that cehck to see you have all the right drivers for everything, and run a virus check using kapersky virus removal tool.

My gx270 PC runs very slow after installing anti virus. what might be the problem?hat might be the reason?


Some anti virus software can use up a lot of system resources and noticeably slow down a computer. The newer and faster computers don't suffer from this problem as much, but on an older computer like your's it can be a problem. I've used Avira (free) on older computers without a problem:
http://www.avira.com/en/support-download-free-antivirus

I don't usually recommend Microsoft products, but Microsoft Security Essentials is not only a very good product and free, but it runs well on older, slower computers:
http://www.microsoft.com/security_essentials/?WT.srch=1

AVG is a good free anti virus also, but it sometimes can slow down a computer a bit. I'm running it on some Netbooks with an Atom 1.6GHz. processor and it does OK. Only way to find out is to try it:
http://free.avg.com/us-en/homepage

Remember that you should only run _one_ anti virus software at a time, so don't forget to un-install the existing anti virus first.

If you purchased an anti virus product and you're stuck with it, this tip may help you speed up your computer:

Also, your may be able to increase your performance with a memory upgrade. If your not sure how much or what kind of memory that you have, download and run this:

Scroll down to the SIW Without Installer (English-Only) version. After it's running click on "memory" in the left margin.

Dell Desktop Windows XP- slow. Desktop tab missing.


You need to find out what process is hogging up your resources and slowing down your computer. Open task manager and look for a process that is using up a lot of CPU, memory or both. Once you have found the process first google the name to see what program it belongs to and if it is legitimate or a virus.

If the process is tied to an application you can end the process and see if your computer speeds up. If this is the case you will need to do a little research to see why that application is so resource intensive.

If it is a virus you will need either use another anti-virus program to remove it or find instructions on how to do it manually.

Computer slowed down considerabily.


Check whether this is not a viral slow down. If not i suggest this

1. Give enough space to the hard drive.
2. Uninstall unused application for a long time and not needed anymore.
3. Install Ccleaner, this can clean your registry, cookies, and other junk files.
4. Defragment your drive. If you have enough space already.

My hp pavilion a800n's fan won't turn off


It is possible that your computer is simply overheating causing it to slow down. There are a few ways to check this. Enter the BIOS and go to the hardware monitor, what temperatures does the computer read both for the CPU and the Motherboard? Another option is to install and run a program called HWmonitor that can be found here. Report back when you can.

Slow performance


Slow computer can be cause of a low RAM of it and also if there's a lot of program/application install on it and also if there's any virus or malware operating on your syste.
The best that you can do first is to try to scan your system with a good anti virus like avast, avira and other to make sure your system is free from virus that may cause it to slow down then if still slow, try removing programs that your not using to free some resources for your computer and the best thing that you can do is try updating the RAM of your computer that will really make it faster..

Hope that helps.........
