Trouble with K7S5A Pro:
I am now currenlty building my 203rd build with the same board(k7s5a Pro) and am always getting contacts from my customers with these problems. Here is a quick reference to what you are experiencing:
1. Make sure you use ONLY ecs verified BIOS with this board. (found on ecs's website)
2. Use the winflash program on the utility disk given with board only. Other types of bios flash programs and such will cause errors.
3. Be sure you use a graphics card taylored to the 4x agp slot/or pci slots. Using a faster or slower video card will cause game play errors.
4. Using the correct bios with the k7s5a pro will enable your 2400 xp to be run at a minimum of 2.0ghz, after uping your fsb to 133/133 in the cmos settings.
5. Trying to go above 133/133 will cause malfuntions. Going below 133/133 will cause your system to detect your cpu at lower rates(ex: 2400 at 100/100 will become a 1800)
6. Be sure your game is compatible with your current graphics card. To check, see game box/manual for exact compatability.
If this wil not correct your problems then it is something i cannot help you with. These are my trouble shooting tasks when I need to correct a problem with a customers build.
PS: I'll try to post a link to ecs's bios page...give me a few minutes.
