Last night there was a storm and a lighting stroke near my office and my PC wouldn't boot properly. When I push the power button it beeps out a error code which I looked up in user manuel and it means fan failure but they spin and this error code only appeared after the storm, I looked into the PC and noticed the capacitors are yellow/brownish on top but the PC powers on and dosen't go any further than'Dell' and half way the bar, I can go into BIOS but there is nothing there, as if someone erased BIOS, there's just a white screen, there would normally be settings, I though it was something with hardrive as it wouldn't boot into windows and I can't even select boot options to boot from my USB stick as there is nothing there. Would this be the capacitors fault? If it is, can they be replaced or do I need to get a brand new motherboard? Thanks.
