Hello and welcome to PC Help Forum.
Turn your computer on and use it like you normally do for about 30 minutes. After 30 minutes
download Speed Fan and install it.
Start Speed Fan. When it is fully loaded, take a screen shot of the first screen by pressing
Print Screen/SysRq on your keyboard. Open Paint and paste. Save the screenshot as a JPEG and post it in a reply to me. Now click on the tab called
S.M.A.R.T.. Click on the dropdown arrow at the top and select your first hard drive. Take a screenshot of that too. Now select your other hard drive and take a screenshot of that too. Post all screenshots in your reply to me.
With this, I can see if your computer's voltages are off, if the computer is overheating, or if the hard drives are giving out on you.
