We don't even know whether you have a problem with a desktop system, or a laptop or netbook, from what you've told us so far .
Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard.
The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.
The specific model of a brand name system is often shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available, if Windows is still working, on the subject computer.
The model is often also displayed on a logo (graphical) screen early in the boot sequence, but it's often not as specific as the specific model number.
