Hello Guys, 

I recently have ran into a problem with my pc (Dell Optiplex 9020) it's power button light was blinking orange like

blink..blink..........blink. I looked up for this issue and found a post it said hold power button for 7 seconds to 9 seconds and then press power button again twice and that worked it got fixed. But why did this problem even occur? Do I have to get my pc checked? Is there anything wrong? Please let me know I am desperate to find out what's the matter.

I also have GTX 750Ti 2GB and after light 4 or 5 months of installing graphic card, my ethernet adapter stopped working. Today when I looked at it it was little bit black on the top and little bit on the side, looked like it was burned, is my fan not helping to cool down my pc? Do I need to install a better PSU?

Please help me out with this trouble.
