underclocking then crashed

I have a acer aspire 5000 with the amd turion procceser 512mb ram 80 gig hard drive. I was attempting to undervolt the cpu for a decrease in heat my laptop has always ran at what I would consider hot. I was using crystalcpuid and I hit .875 volts at 800mhz before I could change it back The screen had a bunch of lines on it then the computer crashed then I hit the power butten to turn it off. Now it just makes a whine noise and wont do anything any ideas as to what I need to do to get this laptop running again? I hope I havent fried anything (too important lol) Any ideas thanks Dj

 

Can you attempt to boot in safe mode? What happens when you put a bootable CD into the drive?

Or does the computer not even get that far? Any beeps from it during POST?

 

Thats what happens when u undervolt too much. The cpu didnt have enough juice to run, so the computer crashed. Nothing bad, just boot up again and dont even undervolt that low or else ur gonna crash again.

 

Yea I did'nt meen to go that low I was hovering over it and I accidentaly clicked

It will not even attempt to boot just a blank screen and when I put power to it either from the battery or Ac-juice it makes a whine'ng noise. there are no beeps lights nothing just the whine. Does crystalcpuid save the changes I made? I was using rightmark cpu utility but I could not figure out the new version but I do know that if something failed when you set the voltage it would reset everything back to factory settings. Does crystalcpuid have this same feature or is the changes I made going to be permenet unless I checked something to make it temperary? I was just wondering if the cpu is mayby set at .850 volts permenatly and that is causing it to not run?

If that is the case will I be able to fix this issue myself or will I have to take it to somebody who truely knows what they are doing? thanks for the help

 

I'd guess it needs a BIOS reset. No idea how to do that though!

 

This is why you should not overclock or undervolt unless you're 110% absolutely **** sure you know what you're doing, and don't mind the risk.


Yes, the changes you made were permanent. They are stored in the bios. Otherwise the CPU wouldn't be aware of them.
And no, Rightmark doesn't necessarily reset everything if it crashes either. It might *attempt to*. But if it gets to where you are, that is, where the CPU is unable to work at all, then it is also unable to reload different settings. If the voltage gets low enough for the cpu to become unstable and crash occasionally, the program you used might (if it supports it) try to reset the voltage when it gets the chance.
If you set the voltage so low it won't even boot? No program can help you, because the CPU is not in a condition where it can execute that program.

So yeah, reset the bios. There's probably something in the manual about how to do this. If not, you can see if you can find it yourself, and otherwise, send it in for repairs.

 

If the BIOS isn't loading, then that is a very bad sign and you will probably need to send this machine in.

 

I don't know how crystalCPUID actually works, but it shouldn't write into BIOS. For BIOS, you should use a flash utility to reflash the eeprom, and I don't think any accident will do that.

You've probably set crystalCPUID at windows startup(still feel that is not possible). Either you boot into save mode by hitting F8 or use some LiveCD to make sure your laptop still function.

For the undervolting, .875V @ 800MHz is kinda low for Turion. My record is the lowest in this forum, but still 0.9V using RMClock on ML-37 with V2000Z. The RMClock is undervolt safe, whenever you crash, it return previous setting.

I can't agree what Jelf said. Undervolt utility won't hurt and affect Windows OS boot time except the crash itself involve the OS get wired. You can either reinstall OS, or use XP LiveCD to boot everything back. Normally, the undervolt only take over the CPU control after OS load it, and that's way after OS loaded lot of critical apps(virus protection).

Your machine should be fine, but probably you need reinstall everything.

Overclocking may hurt hardware by over heating, undervolt won't do that.

 

NO worries mate I am definatly not well qualified in the computer mods/system critical items department but that is why I play around with stuff to learn how these things work. If I never started tinkering with engines atvs and trucks I would not know how to fix them when they break granted I have done some minor damage but I try my best to learn from my mistakes I definatly dont have alot of mony to burn so I try not to be stupid with my stuff But when you are playing/trying to be a pro you are bound to make some wrong choices somewhere. That is were I call on you guy's on these forums and if that dont work I will see if my buddie or the computer shop will give me a hand to sort it out.

I am glad to hear it is most likly the system bios that is messed up and not something well it seems this is majour but not something more expensive majour I'll have a look and see what I can come up with abought the bios and I'll give my buddie a call see if he can offer me some advice thanks for all the help

 

ROCKHARDER,

I cant even get the machine to power up to press f8 or to load a cd.
How do you reccomend to reload all windows components or will it all get wiped clean when I reset to bios? I know it is hard to diagnose a problem over the net so thanks for the help


Anybody have a good read or some info on reseting the bios? or would it be best for me to just watch and ask some questions while somewon who knows what they are doing has a go at it Thanks

 

You could try to get an external housing for the drive and dive into the file on another computer, but that would take a some good skills on the programming aspect of it to do that kind of thing. You would have to know what to look for and change, and I don't really recommend that kind of thing unless you can mess in the bios VERY well. That is the only way that I know how to get the bios changed in your case.

 

I called acer tech support and they said to send it in for warrenty work. Should I do anything before sending it in? I am unsure if what I did will affect the warrenty or if they will even care? any ideas I dont want to have to spend all the mony for shipping then wait a few weeks to have them say it is not going to be coverd under the warrenty lol thanks

 

It's hard for them to tell what happened other than "it's not booting, swap the motherboard". Hope you have your stuff backed up, they don't guarantee that they won't just blow away your hard drive and reload it to factory conditions.

 

alright sounds good then I always keep my important stuff backed up on dvds or online I learnt that one the hard way last year Thanks for all the help guy's

 

Uh, apart from the fact that it *did* hurt in his case?
I don't think I said anything about OS boot time. But you can certainly change bios settings without flashing it. Flashing updates the actual bios software. But you don't need that to change parameters such as CPU voltage.

Of course it hasn't physically harmed any of your hardware (I didn't say it would. Just that it could cause a lot of problems, such as being unable to boot, and unable to revert your settings because you can't boot).

Again, doesn't exactly fly with the fact that his computer won't even POST. That kinda hints that something goes wrong right at the start, eh? About the time it tries to load initial settings from the bios.

And I suspect most people have managed to make their computer unbootable by messing with settings like this. I know I have (when I was first exploring what this strange beast called Bios could do)

The trick is just to realize you've screwed up, send it in to get fixed, and then hopefully you won't do that again.

Anyway, on desktops, there's a jumper on the motherboard which you can flip to reset the bios. Alternatively, you can try removing the cmos battery for a minute or so. I haven't tried this with notebooks, but it should be similar (they might not have the jumper, but there certainly is a cmos battery somewhere, and removing that should have the same effect)

Of course, the ultimate guide to this is your computer's manual. (You might not have one that describes the hardware layout, but there's probably one on line)

Other than that, you can always just try to open it up and look around for the battery.

(Although once you start opening your notebook, you might get into trouble with your warranty if you still end up having to send it in to support)

Well, if they can/do check the bios settings, they can easily see it's undervolted, which typically does void the warranty. But most likely they won't notice (accessing bios when you can't boot isn't exactly straightforward)

But yeah, expect them to wipe your harddrive no matter what. Tends to happen no matter what's wrong with the system you send them.

 

Sounds like he need to drive some screws and check where is the battery according to his manual.

If unplug the battery, shorten the connector would discharge faster than waiting a few minutes.
