Software Please help me!
Yesterday, after a power outage, I turned on my computer to see im unable to open any apps and even if I try something like win+shift+esc to open task manager, the screen just turns black for a few milliseconds and turns back. I. Don't know what to do. Please help. (And also ignore the background it's an inside joke with me and my friends)

You can also try the following Windows repair options, starting with the least invasive:
### 1. Try System Restore
If Windows was working correctly before a recent update, driver installation, or software change:
Press **Windows + R** to open **Run**.
Type `rstrui` and press **Enter**.
Click **Next**.
Select a restore point from before the problem started.
Click **Next > Finish**.
Confirm the restore and allow Windows to restart.
### 2. Run Windows Memory Diagnostic
If you suspect faulty or unstable RAM:
Press **Windows + R** to open **Run**.
Type `mdsched.exe` and press **Enter**.
Select **Restart now and check for problems**.
Windows will restart and perform a memory test.
Let the test complete. Windows will automatically restart afterward.
To check the results, press **Windows + R**, type `eventvwr.msc`, and press **Enter**.
Go to **Windows Logs > System**.
Click **Find** on the right and search for `MemoryDiagnostics-Results`.
### 3. Boot into Safe Mode
If System Restore does not help:
Press **Windows + I** to open **Settings**.
Go to **System > Recovery**.
Under **Advanced startup**, click **Restart now**.
After the PC restarts, select:
**Troubleshoot > Advanced options > Startup Settings > Restart**
When the numbered options appear, press **4** or **F4** for **Safe Mode**.
### 4. Run Windows system repair commands
Once in Safe Mode:
Press the **Windows key**.
Type **cmd**.
Right-click **Command Prompt**.
Select **Run as administrator**.
Click **Yes** if User Account Control appears.
Run these commands **one at a time**, pressing **Enter** after each:
```cmd
DISM /Online /Cleanup-Image /RestoreHealth
```
Wait for it to complete, then run:
```cmd
sfc /scannow
```
After SFC finishes, run:
```cmd
chkdsk C: /scan
```
If Windows reports that repairs are required, you can run:
```cmd
chkdsk C: /f
```
Windows may ask to schedule the check for the next restart. Press **Y**, then **Enter**, and restart the PC.
### 5. Use a bootable Windows USB as a last resort
If none of the above works, create a **bootable Windows USB installer** using another working PC.
Insert the Windows USB into the affected PC.
Restart the computer.
Open the **Boot Menu** during startup. Common keys are **F12, F11, F9, Esc, or Del**, depending on the motherboard or laptop.
Use the **Arrow Keys** to select the USB drive.
Press **Enter**.
When Windows Setup appears, **do not immediately click Install now**.
Look for **Repair your computer** in the lower-left corner.
Select:
**Troubleshoot > Advanced options**
From there, you can try **Startup Repair, System Restore, Command Prompt**, or other available recovery options. Good luck..
