The Speccy shows that the S.M.A.R.T. has a warning. This means that there is problem with your hdd.
I would suggest backing up all of your important data to removable media, like DVD, flash drive, a second hdd, etc.
I would also suggest running a diagnostic test on the hdd, for that you can use Seagate diagnostic tool SeaTools for DOS.
Notice: SeaTools for DOS will run on all manufacturer's hard drives, but may not recognize the hard drive if the Storage Configuration is not set in a configuration which SeaTools will recognize.
If the motherboard has a Intel SATA controller the storage configuration for SATA must be set to AHCI.
If the mohterboard has a Marvel SATA controller the storage configuration for SATA must be set to IDE.
To determined how your storage is configured open the Device Manager and click on IDE ATA/ATAPI controllers.This will expand the tree allowing you to see your storage configuration.
If you need to change the configuration you will have to go into the BIOS to make the change.
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.
