Hey. I've been having trouble with my sig rig for a couple weeks now, and I can't figure out whats wrong with it. My rig won't post! No matter what I do, I cannot get this rig to do anything more than have it spin up my fans when I press the power button. I've tried a cmos clear, reseating ALL of the heatsinks (CPU, NB, GFX), a different video card, different HDDs, different RAM, tested the PSU with a multimeter, and I even ripped the mobo out of the system to see if there was any damage to it (Which there was none). I last thing I remember doing is trying to oc my xp-m a little farther, I think I was running 212x12.5 @ 1.675v w/ 57c full load the last time it was running. I took off the hsf to clean it up a little bit, and when I put it back on a couple days later (I got lazy) it stopped posting, no bios beeps, just fans spinning and HDDs starting up. Anyone have any ideas on whats wrong with my system? I'm thinking it's the CPU, maybe I pushed it too far.

Hmm.. I think it's cpu bro. 1.6 volts is quite mild for a socket A overclock, but over time it could result in processor death. Your motherboard seems to be posting, are there any beeps? Have a speaker plugged in? Try that and tell us the beeps.

EDIT: By the way, the volcano was a pretty hefty heatsink to be placed on a cpu with no IHS, I had one and it chipped my core and broke my cpu, and I had the same results as you *fans spinning, nothing else*. That could be it, inspect your CPU for any telltale signs of a bad cpu. E.g. burn marks, chipped core, any physical change to the cpu.

That's what I'm thinking, bad CPU. I've been running 1.6+ vcore for as long as I can remember, I've had this rig for about 2 years now. I don't have another Skt A CPU or mobo to test my theory, though. Maybe it finally kicked the bucket. And no, there are no beeps coming from the mobo.

Odd. I'd try just a visual inspection then if you haven't already done so. Other than that there's really not much else you can do without a spare cpu or motherboard.

Just checked, and there doesn't seem to be any damage to the CPU. All the pins are good, and the core looks nice and shiny. I do remember, the first time I turned on my computer after reseating my hsf, that the speakers (Actual speakers, not the system bios speaker) made a really loud, weird, pulsing, buzzing/farting noise. I turned off my computer, put my nose up to the mobo (Instinct?) and I could smell that "hot electronics" smell (If anyone knows what I'm talking about). I didn't see any smoke or burn marks, though.

Well from most of my experiences, that real BURN smell comes from literally blowing something right then and there...like way too much voltage or something, but since you say you've had the volts up over time, it may have just burnt out over time leaving no real burn smell....

Yup, i've burned two no name psu's out and have seen smoke from one and the bad smell from both lol

Well I'm getting a new Brisbane/8800 rig in a couple weeks, so this Socket A rig isnt too important to me (P3 Katmai sig rig should hold me for that long
). I just wish I could get a screen of my pcmark03 so I could get into the top AGP systems..

wow - tough one.

Well here's what - give your mobo a drain - put the Cmos jumpers on reset, and plug off the PSU completly.
Leave it for a few hours.

In the mean while you can get an old toothbrush and brush out the RAM and PCI slots thoroughly.
+ take an erasor(normal erasor - preferably the rubbery ones, rather than the more grany ones) and rubb off the contact of your RAm.
EVEN IF it doesnt seem dirty - just rub them thoroughly.
Also, dab the brush with some alchohol, and clean the RAM slot again, and then the RAM modules.

(everything should be dry by the hours-long power drain)

also - remember to make sure that all the other new parts that you're carring in to test. ARE IN FACT (try them AGAIN).. fully functional.

trouble shooting doesnt help when you tools are dead


good luck man.

Nope, scrubbed and cleaned everything, cleared the cmos, but no luck. I tried a spare video card and ram but that doesn't work either. Any other ideas?

Well. If you're sure you cleaned ALL teh mobo slots well.
Disconnected EVERYTHING but the monitor cable (NO NICs ect)

Tried different memory and graphics, as well as CPU. (did you?)
Then your MOBO is probably buggered.

Are you sure nothing is shorting on teh underside of your board?
Did you try another PSU?

I don't have another Socket A chip to test the board, any other ways? Would leaving the CPU out and turning the rig on do anything, like beep? I ripped the entire computer apart a few days ago to inspect the board, so nothing should be shorting it out. I tried another working PSU today, but no luck. I did notice, around the edges of the CPU die, that there's black stuff going up about half ways up the side (Didn't notice that when I first got it brand new, is that bad??). I'm not sure why my mobo would konk out on me, my oc would have only been pushing the NB ~10Mhz higher than stock, with active cooling too..
