fixing issues of windows stuck at logo screen

 If you just powered on your pc and windows gets stuck at the logo screen with infinite loading, no worries, we will just fix it up.

Method 1  uninstall graphic drivers or Update windows

Restart your pc and press (del) delete key to go to BIOS. if this does not work try pressing  F2,F4,F8 or F10 depending on the model of your motherboard.


In the BIOS look for the optimized defaults, load it up and save the settings and exit BIOS. for those who cant load up bios, remove the CMOS battery, wait for 5 minutes and return it . then power the pc up.

then now boot to safe mode in order to uninstall
1. Uninstall graphics card driver
2. anything suspicious
3. or even just update windows 10

 To do this just interrupt the normal boot process 3 consecutive times. To do this  while booting, long press the power button then press the power button to load it back on. On the fourth time, when windows enters the Automatic repair mode, just wait for it to load. 
When it enters automatic repair, click on
 Advanced options
then choose Troubleshoot
then Advanced options
then Startup settings
then click restart.
When it restarts, you will asked to choose what option by number you want. click (F4)

Look for the display adapters , right click whatever graphics you have and choose uninstall device. check the box and uninstall your drivers. you will be asked to restart you pc, click ok and when back on and it works, download the latest graphic drivers. 

in case this does not work, boot it back to safe mode and update your windows.

use method 1 to enter safe mode, when it finally gets to safe mode, go to your search bar and type

try this , type in this:

type exit and restart your windows

If all this fails, get back to the Command prompt and type in
the drive letter of the drive containing your program files and windows file.
to confirm this just type
notepad. 
and hit enter
a notepad should appear and 
click on file
then open file
click on my pc 
then confirm your target drive by opening the drives to check where the program files are located.
for my case my program files are in drive c

type in the drive containing your windows files, (for my case it is local disk C:)
c:
hit enter
type 
dir
and hit enter, you should see the program files and other directories listed
type 
chkdsk c: /f
hit enter. if you get a message such as the one shown below type
and hit enter.

Once the whole process is done, we can type:

bootrec /fixmbr
hit enter, you will see the operation was completed successfully, then type

Illustration for the mechanism for ozone destruction by CFCs

Illustrate the mechanism for ozone destruction by CFCs. The sun emits different types of wavelength, among those, we have UV light (Ultra violet light). The UV light would be very damaging if it were to come in contact with us including damaging the DNA and giving sunburns. Figure 1 types of ultra-violet radiation penetrating into the earth’s atmosphere and ozone layer. As shown in figure 1, we are protected by a layer of Ozone which accumulates in the upper atmosphere of the earth and absorbs the UV radiation (UVB and UVC) before it reaches us. Stratospheric ozone (O_3) is produced by the combination of an oxygen atom (O) with an oxygen molecule (O_2).  O_3+ UV => O + O,UV light strikes an oxygen O_2 molecule, splitting of the O atoms O+O_3↔O_2,O_2  reacts with O to form O_3, since its reversible, UV light also splits O_3to O_2+O In the upper atmosphere, allotropes of oxygen exist. They include O_3, O_2and o. They are all in equilibrium with each other hence they interconv...
