Hello,
Welcome to the Dell Community.
If your system is working normally in safe mode,
it can be an application or video driver causing the issue.
First, you can try to uninstall the Video driver
from device manager (Start - Control panel - Device Manager) restart your
system and check if it works.
Or
Try disabling the startup items and
restarting your computer. Go to Start - Run or Start Search - type MSCONFIG and
hit OK or click on it in the search results - a System Configuration window
will pop up (If you have enabled User Account Control, it may ask you to confirm
if you want to continue. Click Allow) - Select Start up from the Menu Bar on
the top - click on Disable All - Click Apply and Ok - it will prompt you to
restart the computer - Click Restart Now.
See if the computer boots up in the normal mode
now.
- If
it boots up in the normal mode, you will have to check for the application
or the item conflicting with the system resulting in blank screen. i.e.,
you will need to go to system configuration window as mentioned above and
try enabling 5 items at a time (instead of one at a time which takes lot
of time) and drill down to the application causing the issue, uninstall
and reinstall it on the computer if you need it.
- If
the problem persists, which is very unusual - try and run any Malware
and Trojan removal tools to make sure there is no infections on the
computer.
Let me know if you need anything else.
