I installed daemon tools from a cd in my pc, after installation of daemon tools,I opened daemon tools and I was about to mount an iso game file,suddenly my pc off and it is not starting, then I switched off the power and switched on again to start my pc, but no use,it is not displaying anything,just black screen coming and the small red coloured processing signal light of cpu (red light which is located at top left of my cpu) is also very weak, I mean when I power on,for about 2-3 seconds it would be good, in dark red colour, then after it wil be in very light red colour! I cannot understand what happened to my pc, I request, please help me to solve this problem!
