H HP 2000 Notebook PC High CPU usage what does this mean and how do I fix
Usually it is almost impossible for someone to diagnose a computer problem if they do not have access to the computer. However, many times a virus will infect a computer and either tell you that there is a problem and that you need to buy such and such product to fix it, or it will actually overwork the processor (CPU) so much, that windows will give you a warning message similar to the one you are describing. Sometimes the warning message is NOT from Windows, and is in fact from the virus, to try to make you buy their product to remove the virus. From here it is impossible to tell where the message is actually coming from. The single most important thing you can do to protect your computer is to install a good anti-virus program and once installed, it needs to be running the entire time you are connected to the internet. It will start itself after every start-up once it has been properly installed. Every time I reinstall Windows on someones computer that has been infected beyond repair, the very first thing I do is UNinstall whichever anti-virus came with it, because it always is only a limited time free trial, and download and install my favorite FREE antivirus program which never costs money, and only requires a quick registration once per year. That anti-virus program is called Avast Free. The version that costs money doesn't work any better, it merely has more toys for us nerds to play with. My advice is to install that free anti-virus program if you don't already have one installed and operational. Then run a thorough virus scan (as opposed to a quick one). If viruses are present, it will find them and ask you what you want to do with them. The option to repair them rarely works. I usually just choose to delete them, but if the infected file is one that is necessary for the machine to operate, it will tell you and in that case you will want to choose the number that corresponds to moving the file to the virus vault/chest. After the scan completes, if it asks you if you want to schedule a pre-boot/offline scan, choose yes and then click on the option to restart. When the computer starts back up, it will run a scan immediately without fully booting up. This will allow the entire scan to happen without giving the virus a chance to hide an installer somewhere else in a different file, only to re-install itself a few seconds later. The other free program you should use and run a complete scan with is called Malwarebytes. It scans for and removes malware, which are tricky bugs that antivirus programs often cant find. It is also free. Download AND install both programs.(2 separate steps involved, as I'm not sure of your skill level and downloading does NOT automatically install it) I recommend running the malwarebytes scan first. It will ask you to restart your computer to finish the bug removal process. Then run the Avast full scan. High CPU usage can also be a result of having too many programs running at the same time, or several other things like not having enough virtual memory enabled, which acts as extra RAM (random access memory). A safe and secure computer is the best place to start though. If you are already running a trial copy of an antivirus that came with the laptop like McAfee or Norton, you can use it to run a full virus scan instead, but sooner or later when they ask for money to keep using them, you'll be glad to know about a good free one. Note: If you do not have access to another computer, you may want to print these instructions before getting in the middle of these scans, or at least take notes if you have no printer either. Here is a link for downloading Avast free Note: If the links below do not offer the ability to click on them, you will need to copy them and paste them into the address bar at the top of a page. Instructions for copy and paste can easily be found by searching with Google or any search engine: http://download.cnet.com/Avast-Free-Antivirus/3000-2239_4-10019223.html?part=dl-85737&subj=dl&tag=button And here is a link for malwarebytes: http://www.malwarebytes.org/lp/malware_lp_form/
