I have a PB 233 model S606 when i turn it on nothing happens no beeps. The only thing that comes on is the cpu fan and the cpu heats up. i have disconnected everything except the monitor one thing at a time monitor still does not come on. I have tried another monitor that i know works. Thanks for your help
try the memery if you can take out a few sticks and try it then swap them around it's probably ethere your memery or your video card if both if them check out ok the only othere thing is the board
scotter - if it was the memory and, in some cases, the HD, he would have gotten beeps.
The CPU fan is probably jacked right into the power-supply - that's why it comes on. Even if it is connected to the mobo, it probably has a pretty direct feed to the power-supply.
You might have a fried BIOS chip - sounds like nothing in the way of instruction hits is getting to the other hardware. Might also have been a BIOS virus as the system is dead.
You might start surfing the junk shops to see if someone will give you a BIOS chip out of the exact PB system. As PB is a memory, you probably won't get anything out of them. You might try the NEC tech support lines. There is a very small chance that they, as the PB parent company, have access to the PB surplus inventory and can get you a new BIOS EPROM for your system.
I really wouldn't spend too much time on it, though, as there isn't much there to upgrade. Best bet would be to put your efforts towards saving and researching your next motherboard and CPU. Chances are, you can find another new or used board that would use your daughter boards/peripherals and put you in a better place than you are now.
