Problem with Duon system

[TheNemesis]

The system that I recently built, as in my sig is having some extreme troubles lately. One day after leaving my computer on overnight, and coming home from work I hear this strange noise. I try to identify the source of this noise, so I unplugged the CPU fan to see if it would stop it. Sure enough the sound stopped, and I plugged it back in very quickly. The thing is, I didn't shut down before doing this. I look at the monitor and it was blank. I think oh no, and reboot it. It doesn't boot up so I power off and try again. Still nothing, so I clear the CMOS. I turn it back on, and I reset everything in the bios. I then reboot, and it hangs before detecting the IDE drives. I wait a while, and nothing happends. I then reboot again, This time it deteced the drives, but hing on the next step. I then cleared the BIOS again, and reboot. Same thing happends, so I leave it set for like 8 hours off. I come back, power on and it starts to load windows. It hangs on the bootup screen. I then reboot again, and no post. Repeated various different things and nothing has helped. Does anyone have an idea what is wrong?

Thanks,
Jerry.

Did you make sure to touch the outside of your case or your power supply before you touched anything? You may have shorted something. Also, your fan header may have gone to hell. Try a different one. Or your fan may be screwed.

Fan is working, Fan header must be ok, and it doesn't seem to have shorted anything, because it starts to boot sometimes.

You unplugged the fan while the system was running, fried chip maybe? I don't know how long it takes to fry a duron @ 900. But since it boots into windows and just crashes, a fried chip would be my guess.

 

[TheNemesis]

It was unplugged for about 5 seconds, and the time that it was unplugged it was running at about 28 C...

Still couldn't have been good for it

An AMD chip can burn itself down without a heatsink or fan in a matter of seconds. A little longer if a heatsink and no fan. I'll bet that you fried your Duron. they run hot anyway, even with the right cooling. Did you smell anything?

Good Luck!

 

[TheNemesis]

No I didn't smell a thing.

Well I left it off overnight, booted up this morning and fuzzy logic started at like 32 (highest I've ever seen it) and kept going and going and going on up to 40-50 C. So I quickly shut it down, While shutting down it crashed What's going on here? Should I make sure that the HS is on there alright? I know the CPU fan was working alright because I have the side off the case and I could feel it.

 

[TheNemesis]

I just took the HS/F off, and reattached it. It started to boot up into windows, then asked for my windows network password. i typed it in quickly, and it then froze I let it set for a while, and went into BIOS the system health thing said 65 C, and froze. I shut it off quickly and now I am afraid to do anything with it.

 

[Castellan]

Sounds toasty to me, how bout you guys?

Make sure that the entire core of the Duron is making contact with the heatsink, and the clip is biting down on it real hard. Did you remember to apply thermal compound? To apply it in a thin layer, only adding enough so that a slight amount spills out when you push down? If you didn't, and want to now, don't twist the heatsink after applying the compound.

Arctic Silver is your friend.

Sorry to say it's probably toast. You might want to try taking the whole chip out and installing it again, probably won't work but worth a try.

Just pickup another Duron for cheap.

You may have toasted a onboard voltage reg when doing the hot pluging of the fan.
It sounds as if you cpu is freezing from heat.
Try setting voltage in BIOS lower. If you can get it booted, check the health monitoring software to see what voltage is being reported.

With the CPU running that hot, I'm thinking it's probably toasted. As fivespeed5 suggested, I'd just pick up another Duron.

 

[KarVi]

I personally dont think your Duron is fried.

If it was it would not work at all, and since your problems only start to crash when the CPU reaches high temperatures, I think you have to look at the atachment of the heatsink.

Check that theres good contact from the CPU to the surface of your HS/F, and try to put on some fresh Thermal Compound.

It's very easy for a Duron running at 900 to overheat, and if the contact between the CPU and HS/F is the least unstable then the entire machine will be as well.

A guy I know, ran a Thunderbird for about 10 seconds without a heatsink. That, of course, didn't work, and many peoble told him that he had certainly fried his chip (I told him to try the old chip with a heatsink before jumping to conclusions). He went out and bought a new chip and heatsink for it, only to find out that the old chip worked flawlessly, and he had the extra trouble of returning his extra Thunderbird to the store.

So don't panic just yet, and make sure you've got the heatsink proberly attached, before buying a new CPU.

 

[Useful0ne]

I would try as KarVi and others have suggested with the heatsink. Also you should try removing the fan from the MB header & plugging it into its own power lead. As mrbios stated you may have screwed up your fan header by hot plugging the fan.

GoodLuck,

Try connecting your L7 bridges, its possible that the BIOS is not getting as far as setting the voltage. Connecting all the bridges sets the default to 1.85. Its worth re-installing the hsf with fresh Arctic Silver making sure that its completely flat.
