Hi
Kyoob1,
Welcome to Microsoft Answers community.
a)
Is this the first time you are coming across such issue?
b)
Have you turned on Power monitor option/Standby/Sleep/Hibernate option?
If yes then turn those off and check if you are still facing the same problem.
Check if you are facing this issue while using some specific application.
Since you have the full version of windows 7 ultimate, I would suggest you to install it and check if you are facing same problem. After installing it I would suggest you to update
the drivers.
Steps to update Hardware device driver:
1.
Open Device Manager by clicking the
Start button, clicking
Control Panel, clicking
System and Security, and then,
under System, clicking
Device Manager.
If you're prompted for an administrator password or confirmation,
type the password or provide confirmation.
2.
In the list of hardware categories, find the device that you want to update, and then double-click the device name.
3.
Click the
Driver tab, click
Update Driver, and then follow the instructions.
If you're prompted for an administrator password or confirmation,
type the password or provide confirmation.
4.
Restart your computer.
