Late reply, sorry But might help someone at some point It was the PSU!

My PC will not boot when I press the pwr button, but when it is on it will shut down ?...so pwr button works... To turn it on I have to cycle the PSU switch 2 or 3 times. It was all right till two days ago,I did a bios/driver updated and still the same One more weird thing would be that my RGB keyboard stays on when I shut down. any ideas?

Doing cable management(never completely happy with it) ,finishing a "silent" build and then getting coil whine.

I have an assignment at school where I need to show the similarity and difference of this 2(without actually getting a lecture on it).I could do with a hand as from what I have been researching so far it looks like its the same thing?!?! Can anybody give a noob an explanation?

i'll ask about one more thing how can i get it to show Ans as no1 / no2 insted of 0 if no2=0 when i divide?

i have done that and it work,it looks like this now Double no1 = 0, no2 = 0, Ans = 0; String Choice; Console.WriteLine("Wellcome to 'my' calculator...it definitely did not take me 2 hours of tutorials to figuer this out"); Console.WriteLine("Press <F1> then Enter to get started...Simon says!"); while (Console.ReadKey().Key != ConsoleKey.F1) { } Console.ReadKey(); Console.Write("Please enter No1: "); no1 = Convert.ToDouble(Console.ReadLine()); Console.WriteLine("Please chose operation:(+,-,* or /)"); Choice = Console.ReadLine(); Console.Write("Please enter No2: "); no2 = Convert.ToDouble(Console.ReadLine()); // comment here :) if (Choice == "+") { Ans = no1 + no2; } if (Choice == "-") { Ans = no1 - no2; } if (Choice == "*") { Ans = no1 * no2; } if (Choice == "/") { if (no2 == 0) { Console.WriteLine("Ans= ERR"); } else { Ans = no1 / no2; } Console.WriteLine("the operation has been apllied"); } Console.WriteLine("The Anwser is {0} = " ,Ans); Console.WriteLine("Press any key to exit..."); Console.ReadKey(); Thanks

Done,thanks for that

hi everyone I am doing a course on c#...started one week ago with absolutely no prior exp in this,getting frustrated with this calculator. Can anyone tell me what is wrong and why,i don't want a quick fix,i want to learn(you get no cookie for bashing me on making a "simple" mistake) Double no1 = 0, no2 = 0, Ans = 0; String Choice; Console.WriteLine("Wellcome to 'my' calculator...it definitely did not take me 2 hours of tutorials to figuer this out"); Console.WriteLine("Press <F1> then Enter to get started...Simon says!"); while (Console.ReadKey().Key != ConsoleKey.F1) { } Console.ReadKey(); Console.Write("Please enter No1: "); no1 = Convert.ToDouble(Console.ReadLine()); Console.WriteLine("Please chose operation:(+,-,* or /)"); Choice = Console.ReadLine(); Console.Write("Please enter No2: "); no2 = Convert.ToDouble(Console.ReadLine()); // comment here if (Choice == "+") { Ans = no1 + no2; } if (Choice == "-") { Ans = no1 - no2; } if (Choice == "*") { Ans = no1 * no2; } if (Choice == "/") { if (no2 == 0) { Console.WriteLine("Ans= ERR"); } else { Ans = no1 / no2; } Console.WriteLine("the operation has been apllied"); Console.Write("The Anwser is = " ,Ans); Console.WriteLine("Press any key to exit..."); Console.ReadKey(); Not sure if it matters but i am using ms visual studio 2015 thanks if anyone will actually help!
