Hi, my computer is hp a1430n, and I was playing battlefield 2 and suddenly my screen turned black. I tried many times, and sometimes when my screen goes off, I also hear my computer beeps (mono tone continuous long beeps), is this hardware failure? It never happened until recently, and I have had this computer for 5 years. My system spec is Athlon 64x2 4200+, 939 socket, Geforce 6150LE, Bestec 300w. Can someone tell me what's wrong with my pc and what the beeping sounds mean? Thanks.
