Bad processor in Acer Motherboard??
Doing a little investigating. Someone brought me a dell dimension 4300 with a 1.6g celeron, 400 fsb. It took a surge from a lightning strike. power supply is bad, with no output on the 5V leg. used known good ps to power board while using a post card. postcard dead as well. Took processor off and put onto a known good acer mobo w/ socket 478, good power , good memory, connected fdd, onboard video, postcard led's indicate good clk, bad bios, good OSC (what IS that?) good 3v, 5v, +12, -12 and the hex will read FF or 97. processor is cool to touch. (yes, I had the heat sink on it)
500 points for the response with the best explanation of what i'm observing.
One other thing... there's a RED led on the post card that flashes 3 times, maybe 3 seconds apart. it says RST..
Any help appreciated..

You said it indicated bad bios -- then this should be replaced or Reflashed
BTW what is this postcard you use?

oh yes, OSC is the short for OSCILLATOR, that 's the engine which generates the basic clock which drives your cpu, and everything. It is measured in KHZ, or MHZ and now Giga herz

Sorry all,
Lost track there for awhile. The processor is in fact cold to the touch. I did not consider flashing the bios... Thanks for the other info folks- I'll let you know if resolved or not soon. Thanks

Well it worked fine for about a month and now it's gone futt again. £50 down the drain again
did you set the jumper pins for the processor clock speed ?...that would be a good idea.
also the led flashing three times is an error code....usually in sync with the system beeps...if you don't hear any beep codes, maybe your beeper is broken.

split between mangolata and nobus for best answer(s) I did not split correctly, nobus go to my open questions and leave a comment in the open question to you and i'll give you points. thanks...
BTW, since that system never booted, there was no way to flash the bios. the processor and mobo were both written off as dead

and OSC I believe usually has something to do with the MHZ of a system??
