That looks to be about 3 years old so without knowing the rest of the PC there could be a hard issue here.

As to Startisback, next time try the FREE one call Classic Shell. Some apps when they are not activated, lockup.

But the i5 has it's own video so by pulling out the 660 we get about 100 to 150 Watts of power back and start sniffing out this old machine's hardware issues.
