got a problem with my old pentium 4 system, basically i have built it up cant see nothing wrong with it but when i switch it on it just freezes at the first 'splash screen' (using RS400-A Board if that helps), i feel like i have tryed everything here, i have cleared the CMOS using jumper and even tryed the bios protect jumper 'in hope' but that hasnt worked, the only thing i could think of after that was removing the 2 PCI cards that i had in there but that didnt help either...
so im totally stuck and dont know what to try next. it wont let me use the keyboard either (it flashs at start up then i cant do nothing with it after that, even num-lock wont work
)
