I went here: Acer Support - Aspire E380 Specifications
According to that, XP is the latest OS it supports.
Then I went here: Acer Support - Download Drivers
I plugged in your computer model, and I see it has drivers available for Vista, but not 7. The Vista drivers are dated 12/11/2008, which is considered incompatible with 7.
I then researched your individual hardware, and tried to find some newer drivers.
Here is a chipset driver that MAY work. No guarantees, it might not even install.
NVIDIA DRIVERS 15.49 WHQL
I wish you the best of luck, but honestly, your system just might be too old to run Windows 7.
