What to Do if Your Computer Becomes Unstable? Part I

Unstable operation of a computer means its “dormancy”, slow loading, regular blue screens with error messages or just “Blue Screen of Death”.

Such instability may occur because of various defects both in the hardware and the software. For example, your hard disk is too fragmented or full, or you try to launch the program which requires more free system resources. If such instability has occurred after modifications of any parameters in BIOS, reboot your computer immediately and return to the previous or default values of these parameters.


Open the main menu of BIOS and select “Load BIOS Setup Defaults” (“Load BIOS Defaults”, “Load Setup Defaults”). To perform this command faster, you can press F7 (F6). Press Y button in the opened information window and all parameters will be set as defaults.

The worst situation is when your computer does not react on modified parameters in BIOS. Furthermore, you may not open BIOS Settings using usual tools if the changes affected processor, memory or video card: it may be either unavailable or invisible on a screen. To solve this problem, you should set default values for parameters in BIOS manually.

To do this, you must first switch off the computer. Then remove the hood, find the battery mounting on a motherboard and gently unplug it. Then carry out the described actions in reverse order – insert the battery, close the hood and switch on the computer.

Some motherboards have got the system of automatic restoration of initial BIOS values. This system activates when it is impossible to boot a computer with the parameters set by a user. So, if you try to assign values to BIOS parameters that might cause a clash between devices when computer restarts, the default values will be automatically uploaded in BIOS. Then a computer will reboot automatically.
