My home computer was just out of order. It is failing to restart time and again after several computer starting try. UPS is on right condition, CPU is also working right but it is failing to restart again and again. So, it seems the problem lies with either motherboard or with some other third party utilities that has been connected with computers.

My home computer has been the not so branded computer, in other words it is an assembled computer. So everything needs to be bought separately so that computer can receive WiFi signal so separate WiFi receiver USB drive, the stereo or sound system needs to be separate audio systems and that to be connected with computer through USB drive for powering of audio systems and audio system to be alerted with the pin connceted with centrqal processing unit.

Then after removing audio systems from computer, now it is running as usual and the system began to boot again and it is now in the perfect condition. So it seems that the problem with the conncetion of third party audio system that has been connected with computer and after removing that Windows boot again without difficulties. Now windows able to boot without difficulties and after booting windows enters into its dashboard state. Now I have seen that entire visible window is upside down and it is no longer in the state of normal horizontal window to now vertical window.

This means now I have the computer screen with sideways display which means working with it remains extremely difficult and now after some research I found its real answer and these are on the following lines.

Windows 11 and Windows 10:

The sideways computer screen orientation is called as screen orientation. Select Start and then type settings and then system and then display. Then choose screen orientation from drop down list table. it should be next to Display orientation. From drop down clcik landscape, then the prompt will come as to keep the changes.

Windows 8:

Click on Windows button at the lower left hand side of task bar. Select Control Panel. Then Appearnace and Personalisation. Then choose adjust screen resolution. hen select orientation and from their go for drop down menu and then select Landscape. Then select Apply to convert screen from portait mode to normal landscape mode, then the prompt will come as to keep the changes.

Windows 7

Select Windows button from the lower left hand side of the screen or click on the windows button and then go to appearnace and personalisation and then go to adjust screen resolution. Then go for change the appearance of your display and then select orientation and from its drop down arrow and then choose landscape. Then select apply to rotate the display to its right horizontal mode.

Then from display settings dialogue box select keep changes to settle to its normal orientaion.

Use a keyboard short cut:

These short cuts work differently on different hardware configurations and software implementations with it. You need to enable hot keys manually before implementing these on Windows computer. Following you can enable hotkeys through these procedures.

Right click on an empty area of desktop. Then click on graphics settings and then choose control hotkey activation. If everything work nicely then use following keys to correct sideways or upside down screen orientation. You can use following keys to make windows screen in normal mode.

Ctrl+Alt+Up Arrow
Ctrl+Alt+Down Arrow
Ctrl+Alt+Left Arrow
Ctrl+Alt+Right Arrow

I hope all of these information could rectify windows display orientation and if after all of these still it does not work then you can comment in the comment section so that I can help you further.
