Turned off computer by switching off the power supply, now computer wont go into windows?
Topic explains it all, my computer was lagging so i turned it off using the power supply switch, now it turns on but wont go into windows, i get a blue screen that flashes, not enough time to read anything. 
Please help
Now i can hear something turning off while the computer is sitll on, it must be the hard drive. This means i must buy a new one?
It is most likely from defaults. Sometimes when you completely unplug the power to your computer it resets everything to default. Plus it isn'tt safe to shut of your power supply it damages your computer sometimes. What you might want to do is to directly boot to windows from the boot menu. When you start up your computer it will have things in the corners telling you options for start up like esc=boot menu or f8=options. Whatever your button for the boot menu is push it (its varies by computers) After this comes up select the hard drive that windows is on and see if it works.
If this does work you will want to go into your system options and change the boot priority.
It could even be that you have a virus or trojan on your computer which means you would have to completely reinstall windows.
Switching Power Supply
Switching power supply is a power supply form factor that incorporates high-frequency input switching to generate desired DC voltage. The use of switching regulator in the circuit makes it a regulated power supply system.
Switching Power Supply: An Introduction
Switching power supply provides modulated power supply by combining low-loss electronic components such as:
-
Inductors
-
Capacitors
-
Transformers
These power supply systems enable electronic connection through switches to regulate the power relay function. Effective circuit status switching between power on (saturation) and power off (cut off) generates required power supply for the device. The switching power method utilizes higher frequency than the AC supply, thus creating a continuous waveform. This facilitates the output supply to a smaller transformer than the input one.
Switching Power Supply: Advantages
The switching power supply method has gained global recognition as it offers the following advantages:
-
It can generate any voltage with little impact of input variations
-
It produces higher efficiency due to the use of low-loss components and duty cycles in power regulation
-
It has a small size due to high operating frequency
-
It features low heat generation
-
It is light weight
-
It produces minimal noise when switching frequencies of the power unit
Low-cost switching power units can produce noise due to input operations. Also, electronic design to connect inductors, capacitors and transformers pose severe challenges.
Switching Power Supply: Classifications
Switching power supply method can be used for four different input-output combinations:
-
AC to AC – in the form of a frequency changer
-
AC to DC – offline DC output
-
DC to AC – in the form of power inverter
-
DC to DC – in the form of voltage converter
A good switching power supply mode maximizes the performance of the electronic device in which it is installed. It demonstrates top performance by regulating input and output supply. Several electronic production companies manufacture switching power supplies and assist clients in choosing the best one for their devices. Custom switching power supply systems are also made for specific power regulation requirements.
