my computer is going slow

maybe your computer is infected with malicious code(s) maybe your operating system has developed some faults and you need a format maybe your file cluster is not organized (perform a defrag) maybe you need to increase your paging file maybe unnecessary programs are running in the background maybe you need some hardware upgrades

Try using advanced system care. It clears out most of the problems. Plus it should clear up some ram. It shuld reduce its slowing by 20%- 30%. And try upgrading the ram to 2GB at least.

Use ccleaner, scan the drive for errors, defrag the drive. After that see how it works afterwards.

it may have a virous or it is too old to work

You can get rid of unnecessary files that take long to load. Keep your desktop as light as possible. If it is the net speed you are talking about then the provider may have problems which are temporary. Sometimes when there are several windows open some animations keep playing in the background which slow the process of your computer.

The best and easiest way to boost your computer's speed is use a good anti-virus plus a good system tweaking utility software. If you cannot get your speed as it was before even after installing and scanning using the softwares then format your C Drive and install a fresh copy of OS (operating software, like Windows) and after that install anti-virus and system tweaking utility software as soon as possible after the installation to the OS. So after this scan your computer every week using the above said software to maintain the systems speed as fresh for months ahead. I hope you got my point.

the best practice is using tools that you can find in the internet. Why your PC going slow down? Your files in PC growth in size everyday. You need tools like disk cleanup or defragment tools to keep your files in good condition. There are many malicious code that spread over the net, this malware will attack your registry key and make your PC going down. You need tool like regsitry booster or regstry cleaner to keep your registry clean and fix from problems. Perhaps you need more RAM or Hard Drive good luck

Have you tried cleaning out your system? Every so often you have to do that to keep the memory in good standing. Run a disc clean up, defrag your hard drive. It is recommended to use the program that came with your system. Downloading other programs unneccerally can cause a host of other problems that you may or may not be prepared for. Go through your program listings and delete any programs you don't want. Turn off start-up programs you don't need. All of this can be done through systems your computer already has. System tools is your best friend. It is there were you'll find ways to clean the system. Most systems even have a "disc cleaner" that goes a bit more then the disc clean up. It'll try to remove any broken or damaged parts giving your hard drive more fuctionallity.
