Question about Dell OptiPlex 780 MT Desktop Computer (Intel Core 2 Duo E8400 160GB2GB) (VARGCC21)
Posted by Anonymous on
It's usually either heat or bad sectors on the hard drive.
I'd take the unit outside, open the case, and spray all the dust out with some compressed air.
If that doesn't resolve your issue you could run a hardware test, most Dell's have hardware testing utilities built in.
Best of luck!
