Problems with mobo...or processor?

Hi all:

Woke up one morning and my screen was blank (power was still on) and could not get any video when I rebooted. I went out and got a new mobo, RAM and processor. Everything else is the same and the PC is back up and running great.

I tried everything to troubleshoot this - different RAM, different video card, reseating the processor, disconnecting all other peripherals. I tried having the motherboard out of the case sitting on cardboard with only the essentials plugged in...no dice. The only time I got it to boot up (beep then have video) was when I put the processor in the freezer for about 10 minutes. Even this was sporadic though because once it warmed up it locked up again. Repeating this process did not ever get me to boot up successfully again so my thoughts that it was a mobo/proc heat related issue went away. I checked all the power supply voltages (I'm using the same supply now) and all were OK. Mobo is a Gigabyte 8ID533 and processor is 1.7GHz Celeron. Both have been working great for almost 3 years.

Any ideas? If I could just narrow it down to a mobo or processor that would be a good start. Not sure what the likelihood of a processor failing is though. Could a virus have infiltrated my BIOS? The fact that I could get it to boot once indicates this not to be true.

Thanks,
taco
 
interesting.

maybe JUST the mobo was shot. i would have just bought a new mobo to start off. But if you were planning on upgrading you did.
i would have to bet just the mobo was shot.

it wouldnt be temps because it would auto shutoff.

and if that mobo has no integrated graphics and just the card you bought i bet it could have been that too but seeing how you just replacest the mobo and now it works that couldnt be it.

id vote mobo


edit: did you try flashing bios? like changing the jumpers? i dunno it may have been bad or somthing
 
I woulda taken my chip my video card video card into your local shop and get them to test them, if they worked then you know it was the mobo, otherwise you know what worked and what didn't

did you have a power surge or anything that night??
 
Sounds like the motherboard to me, that just the first thing I would test! I've seen some boards go out in weird ways!!
 
na, i think he may not post here again . :(
but like i said that the mobo was shot.
i wouldnt have got a new processor cause believe me or not, a processor isnt cheap
 
Thanks for all the replies....:o

Yes, with the new mobo, I kinda had to upgrade my processor because the one I had (1.7G Celeron) wasn't compatible with the board I got. I figured, since I'm replacing the mobo I may as well upgrade. $168 later I'm running a nice PC with a 2.4GHz Celeron D and 512MB RAM.

I would think that it is the mobo too. I would hate for the local shop to test it and have it work for some odd reason then get it home, put it together then have it die on me again (because of the intermittent nature of the whole thing). If I come across another socket 478 board in my travels I may test out the processor.

No power surges to my knowledge that night. BTW, is there a way to flash BIOS when you can't even get video??

Then that means you're doing something wrong with your configuration...
 
I'm doing something wrong with my configuration??? What excactly does that mean? It couldn't possibly mean that I'm doing something wrong between powering down and simply powering up and having the mobo do two different things! It's not as if when it runs, it runs hunky dory until I power down again - it froze that one time and never recovered. And why would it suddenly fail overnight as a result of something I did (or, in this case, didn't do)?

Electronics' toughest problems are intermittent problems and heat related problems. Very tough to track down and not traceable to a person's actions or in this case a configuration. I've been around this block many times and it doesn't get any easier to explain.
 
well, if you HAVE TO flash bios, do it.
but otherwize, if your not clear what your doing DONT CHANGE SETTINGS
they are set at these default settings because they are the most stable and recommended configurations.
im not saying you did change anything im just saying for future preference:)

for all we know, maybe you mobo doesnt like a peice of hardwear on it.

Also, maybe a resister failed and fried itself, or you had a surege or for some reason got extra or lower voltage surge and the mobo couldnt handle it.
freakish things can happen. jut now, i could get some weird thing and a japanese transister could blow
 
Hey, is there a way to reset BIOS on my mobo? I haven't looked in my book yet but is there a jumper to reset it or can I remove the coin cell? I'm asking because there is no other way to flash my BIOS since I can't get any video. Maybe I'll try it again since it's been sitting for about a month now!
 
you haven't been around the block enough times....I do it for a living

have you reset the cmos?
the little jp1 beside your cmos battery?

and by taking it into a shop in the case it would be no different than powering up at home....BUT if the shp is good they would remove everything and do a diagnostics check using tools that you can't possible comprehend at this time...in which case they would narrow it down to one specific problem and save you a lot of money, but at the cost of your nerdly boyhood
