I have to say I'm not very good at recognizing faults that our daily electronic equipments give us especially the computer even though I have been into it for a few years. The recent move of my whole desktop and my speakers and reassembly of it troubles me when there was no sound emitting from my speakers. I tried whatever I could, from software to the whole tiring process of reformatting my desktop. I need a reformat anyway. And finally I noticed that it was my built-in sound card which has failed me. Now, it's back to square one, buying myself a new sound card, hopefully, a better one.
