Hi everyone. My computer seems to be having some issues after a small thunderstorm hit about 2 weeks back and I'd really appreciated any advice I can get on the matter. The pc was working fine the night before, but after I came home from work the night of the storm I tried to turn it on and got no display. It was connected to a surge protector, but that's still pretty suspicious timing.
When I hit the power power button the lights turn on and the fans spin, but then it hangs on the A2 error. First I tried different HDMI cables and plugging it into different ports, than I hooked it up to a different TV altogether (I use my TV as my monitor, don't actually have any monitors) and the same thing still occurred. When I opened it up I made sure the hard drive and dvd drive were connected properly. I also reseated the video card and tried it in different slots. When I did this, sometimes (rarely though) the A2 error didn't appear and it showed the temperature instead, but the problem still persisted. I also tried just booting with one stick of ram, but there was no change. My motherboard has no on-board graphics, so I couldn't try that sadly, though I did try clearing the CMOS.
Would anyone have an idea on what the issue may be or know any better ways I can troubleshoot the problem?
