Even though running a brand new computer, some users at some point of time find the computer randomly stops working. Some will take it as granted that the worst has happened and it’s time to buy a new computer. No!!! This is just a waste of money! Every computer, new or old, can come to the chance to stop responding due to several unknown reasons as you can learn HERE. No matter for whatever causes the computer stops working, try the following solutions before trashing it or taking it to a computer repair store. I think you will get surprised!

Firstly, restart your computer when the computer stops working for the first time. There are some chances that the computer randomly stops working problem was caused by some temporary problem with Device Manager. If this is the cause, a simple reboot might fix it quickly.
Then, totally wipe out spyware and malware from your computer. Spyware is notorious for it has the ability to infiltrate into your computer, drastically slow down your system performance, severely damage your crucial system component and transmit your private or business files to insecure remote servers for commercial or personal purposes. To completely remove spyware and make computer run properly all the time, you should have to enable a reliable spyware removal tool on your computer which has the power to fully detect, block and remove Spyware, Adware, Keyloggers, Trojans, Worms, Hijackers, Rootkits, Password Stealers, Tracking Threats, Rogue Antispyware and other Malware attacks.
Thirdly, remember to avoid overheating. We all know that if the computer is being running too long, the CPU will become very hot. Hence, some of the hardware will become too hot and fail to respond, which results in the unexpected computer stops working problem. So do remember to let your computer have a break if it is running for a long time and place your computer into a well-ventilated room, and check your fan is always working well.
Fourthly, uninstall unneeded or undesirable programs. You may have never noticed that how many unwanted programs you have installed on your computer, especially on C:\. The programs on C:\ need to consume system resources while they are running for some of the software manufacturers attempt to gain profits through requiring its components to run at system startup. The more programs you are running from C:\, the more system resources the components consume and the more chances for you to suffer from “computer randomly stops working” problem. These components can dramatically reduce the system performance and slowdown PC speed seriously. To maintain computer performance, you may consider enabling Windows Add/Remove app to uninstall the large bundle of the programs you have seldom used.
After checking and fixing software problem, remember to troubleshoot and fix hardware issue, too. We know that Hardware is needed to make the system perform well. But as you install new hardware and update the outdated drivers, it is likely that you may corrupt something and cause the “computer randomly stops working” problems. At this time, you need to make sure that all of your updates are updated to the latest ones and it is better that you can go to the manufactures’ website rather than other unknown sites to download the exactly correct & certified new version for your computer. Besides, you should install all available Windows Update as this sometimes solves the problem.
If possible, add more Ram to make computer run properly all the time. We know that no matter which program you are running, it require a lot of RAM space to run properly. System cannot respond your action on the computer immediately and you have to wait for a long time when there is insufficient RAM on the computer. So to make computer run smoothly, if possible, you can add more RAM for your slow PC. This is a great and effective way to fix slow computer problems and make it run properly.
Last but not least, you should run a system repair tool to scan and check your PC’ health. Such tools will quickly check the registry and the rest of the computer for errors. When uninstalling a program from your computer, some registry entries will not eliminated completely. That is why registry errors are also a main cause for “computer randomly stops working”. So, the last solution I want to say here is to check all the registry entries and remove all computer registry errors.
In a word, a computer can stop working under many unknown environments; however, the solutions above help to maintain stable computer performance and prevent “computer randomly stops working” issue effectively. So why not start performing them from now on??

I recently got the S.M.A.R.T. HDD virus and after attempting to get rid of it, my comuter stopped working. When I turn it on, it starts up with the Dell logo as usual, but then it goes to a black screen with a blinking underscore that I can’t control. It stops working! Great solutions to show me how to deal with the problem.
