It is a
Celeron(R) CPU 2.93GHz
Packard Bell computer intel(R)
192 mb of ram
Good processor but low on RAM.
256-192 = 64 MB being used by the video.
Adding a graphics card, if possible, which has its own RAM, would allow you to return the 64 MB for use by the system so you would have the full use of 256 MB.
Adding more RAM, depending on the number of slots and the maximum for the motherboard, would then improve the overall capability.
