I was surfing in some tech forums when I came across a subject titled "Fix Blue Screen Death". The blue screen of death syndrome happens randomly. Symptoms include a blue screen popping up and the message reads if you have installed any new hardware or software in the past. I've personally had problems with this and it can happen to any computer and not necessarily because of a virus.
There are some solutions to this.
The blue screen death pops up when your computer starts to access data from faulty parts of your RAM . For example, the worst case blue screen death scenario is when you have an anti virus software installed that loads automatically on default whenever your computer starts up. In order to load your Anti Virus software, requires for data to be passed from the RAM. When faulty regions of the RAM are accessed, the blue screen errors screen will pop up, and everything freezes and the only button that works is the on, off and reset button. If you have 2 sticks of RAM, just open up your PC casing and test the RAMs individually. By a simple process of elimination, you'll find out which RAM needs to be replaced.
Another approach is to test for a corrupted registry by running a registry cleaner software. Your computer's registry contains data about your computer, from the hard disk, printer, video card, all software that's installed on your personal computer. Drivers are contained within the registry in order for your computer's components to work. Over time, the registry can be cluttered with tons of software and obsolete information that we no longer use but simply stay in the background, like little parasites. This eats into the CPU resources and can result in slow booting up of the computer, delays and temporary screen freezes when opening Microsoft word files, PDF files or slow loading of multiple Internet Explorer window tabs. A registry cleaner will search for registry errors and a possible solution to fix blue screen death. At the very least, it will increase the speed of your personal computer.
If both the above solutions don't work, the final problem could lie with the power supply. The power supply is firmly embedded into your Personal Computer, so I don't recommend for anyone to remove this. In this case, I'd recommend you bring your computer to your local PC shop to have it checked.
