  1. I have to under-clock my Amd Athlon xp 2800+ (barton core) its stock Front Side Buss (FSB) is set at 166 and the multiplyer is 12.5. I have installed everything correctly all drviers when i go to play any game i get blue screens,quits game automaically,resets.

    I fixed this but i had to under-Clock my FSB to 160. Why do i have to do this to get it to function correctly :eek:
    Cooling is not the problem as i have 5x90mm case fans 1800rpm-3000rpm.

    Any Suggestions ?

    Sounds like u may have a ram or graphics card issue, u need to check them thoroughly.

    I know its not graphics problems becuase it has happened with all 3 of these different graphics card. geforce 5200,geforce 5700le,ati 9700pro. Ram is the same thing i have had kingston hyper x,Corsair low latency,generic.

    Im wondering about a bios update becuase i still have the first bios but i dont think i should update as my problem isnt listed in a bios fix.

    Ok i have 2 more suggestions then.
    Firstly, you could try decreasing your cpu multiplier and increasing the fsb to match. For example, it should run at 166 by 12.5 which equals 2075. so u could try 207 by 10 for example.
    Secondly, check all of the capacitors on your mobo for damage. Usually if one or more have blown they will have domed instead of flat heads. Also check if any feel wobbly as the legs can sometimes become detached internally. Be extremely careful when doing this as they are not very tough components. If u find ant blown ones they will need to be replaced.

    I downloaded Fuzzylogic 4 not long ago and i looked at the front side bus speed and it saya that it is 168.9 in the picture its a bit hard to see. But in the bios it is 160 what is going on here. it is not always say it is 168.9 most of the time it is 160 like it should be. What is happening here. Also i have a program called pc alert 4 both made by msi for my mainboard and pc alert says that my cpu is over 100degrees celcius. weird.
