What is the model of this Aspire?
To rule out the possibility of a problem with the hdd I would like to run a diagnostic tool.
Please download SeaTool for DOS.
When the SeaTools for DOS website opens click on I Accept, then click on the Download button in step #4.
This download is a ISO image which you will need to burn to a CD in order to create a bootable disc with which to run the diagnostic tests.
To burn this ISO file to a CD or DVD please downlaod ImgBurn
and install it.
Insert blank CD or DVD into your CD/DVD drive.
Open ImgBurn, and click on Write image file to disc.
Click on the Browse for a file icon:
Right click on the Start orb
, then click on Downloads
. Scroll down to the SeaTools for DOS
download and click on it. This will load the ISO image, you will see the information listed as it is in the image below outlined in red.
Click on the blue arrow (also outlined in red) to start burning the bootable CD.
Once the disc is created load it in the CD/DVD drive and restart the computer.
Please note: You may need to change the boot order in the BIOS so the CD/DVD-ROM is the first device in the boot order, and the hdd is the second device.
Please run the long test and include the results in your next post in this topic.
