Computer wont boot

[Darksteel]

heh, at least I had a hs and fan on mine so they're going to replace it. How long would it take a processor to burn up with no hs or fan on it though? seconds, minutes, longer? Not that I'm stupid enough to actually try it out, just curious, cause the guy from the company I bought it from said that it was probably caused by an improperly installed hs/fan and unless it can burn up in a matter of seconds it couldn't possibly be that. (and even if it could I doubt that's what caused it since both me and my friend fried our cpus)

Trust me. You can fry an Athlon CPU in a matter of seconds. In fact, Tom's Hardware did an article on that. I'll see if I can't dig up a link or two.

They tested a P3, a P4, a TBird Athlon, and an Athlon XP for thermal shock (say the HSU falls off or something) and the two Athlons failed miserably. Both CPUs got deep fried and the TBird even took out the mobo with it. The P4 just slowed down quite a bit and the P3 crashed, but no biggies. They both worked just fine and dandy when the TH guys put the HSUs back on and rebooted the computers.

After a mere 5 minutes of searching, I find the link.

Have fun and don't try this at home, kids.

[EDIT] BTW, don't miss the movie at the end of the article. It's a showstopper and demonstrates what they were talking about perfectly. [/EDIT]

There are numerous warnings on the literature that comes in the retail package regarding frying and how it can happen in seconds.

Watch Tom's movie for proof!

but i belive that was under full load...playing a graphic game at ful frame rate...

i got a t-bird 1.1 ghz on an asus a7v133.

i took the machine apart to clean the filters/dust and see if i had an neat mice/nuts/kids' toys in the case...putting my machine back to gether again i forgot to plug the fan back, now the h/s was attached to the cpu, i would boot into xp, then 1015 minutes it crashed and started to make a funny noise (alarm)..

seriously smell the board, cpu...if it's fried it stinks.
reseat...
take a voltimeter/multimeter what ever you all call them, and see what the red and yellow are running at, if it's not consatant then it's no good..

you said that your friend had the same mobo....did they get it workin? if so swicth out with them, cpu, ram, psu...

At least in your scenario you had a HS on, so that helped tremendously

ok, i really wouldn't think that a processor could burn out that fast,but apparently so. My processor wasn't burnt up that badly though, but it also wasn't running quake 3. Since both of our processors burnt out as soon as we turned them on though we have to wait for our replacements before we get our comps up and running.

[ilovetheusers]

If they had fans - any idea why they burned up? Hope they didn't take the mobo out too.

[Darksteel]

Our theory is that the processors we got were from a bad batch somehow since both of ours burnt out the exact same way. There were fine black spiderweb like burn marks that look like there could have been some arcing on parts of the processor that werent near the core. It doesnt look like the mobo took any damage though, so hopefully it's fine. The burn marks were fairly small compared to the ones on toms hardware's test so i dont think the heat was enough to damage the mobo. We'll have to wait and see though till we get our replacements.

If you have an extra usb cable that connects onto the m/b try taking that off I have seen that sometimes the wrong configurations on the usb cable with stop the system from booting up even though there is one way to plug in it could be that unit

i recently experienced the same thing with a client and i determined it to be the power supply and/or the motherboard (try just one fan connected to the power supply, you may have to use the atx pwr shorting method). please let me know if you find different.
