thank you for the answer
I run a Pentium(R) 4 CPU 3.00GHz, 2.99 GHz, 2.50 GB of RAM, Windows XP Ultimate Edition, Intel (R), Service Pack 3
I will have to open the case to check the PSU, but I think it is good.
My computer right now has a nvidia GeForce FX 5200 (Gateway) and an Intel(R) 82810 Graphics Controller.
I am replacing for a Diamond Multimedia ATI9250 256\M 128BIT PCI TV DVI because I want to connect two monitors.
