Computer running VERY slow on Start up?

Every time I load up my computer in Normal mode (I've been using safemode for the last few months) It loads TOO SLOW to uninstall anything or even try to download software, its VERY slow it could take about 3 hours to open 1 application

I'm trying to fix this computer I'm tired of running on safemode I can't listen to music Play games or even download things to my iphone with safemode, somebody please tell me How I can fix this issue without using Normal Mode

According to my opinion I think the best option is to format you PC and begin everything again. And if you are not in a condition to perform that action, Consider checking these steps.

1) Check whether you have viruses in your PC.
- If you find any threats Try cleaning your PC with a Anti virus Rescue Disc. And after doing that install a good anti virus.

2) Try cleaning your Hard disk.
- For this I recommend Using the Preform Cc leaner ( www.ccleaner.com ). Download it. And clean your hard disk. And clean the registry as well. And also perform a Driver Wiper Process.

3) Remove Heavy games you have installed. And use a software like Game Booster when you are gaming.

- In Safe Mode create a new user, with administrator privileges and protect it with password.
- Remove unwanted software's & programs.
- Empty the Recycle Bin.
- Download reliable program RegInOut to fix OS registry properly.
- Run disk clean up (start > programs > accessories > system tools > disk cleanup.)
- Disable background services.
- Restart your PC normally and log on to the new account created.

Enter into safe mode, uninstall unnecessary programs and browser extensions, eliminate suspicious files or exe on system32 you recently installed and fix registry issues.
Then you can ran a antivirus to take a deep scan.
This method can remove most malicious viruses if you have a strong computer knowledge.
