Using the search feature is a bad idea, it accesses the disk more than is needed. It should be in the folder mentioned above.

How old is your machine? Mine died last week, motherboard problems, capacitators mushrooming (whatever that means)
If you look at the verticle cylinders(electrolydic capacitors) on your motherboard, you'll notice they all have flat tops. It's an interesting story behind this problem, you see an engineer stole the specs on the electrolyte for new aluminum capacitors that his company was working on before he moved and started working for another company. The problem is, these specs had a few intentional boo-boos in them, and only the engineers working on the project directly actually knew about it. So, the caps work for awhile, and then they start to swell, or even worse, burst.

The only data I needed, they didn't move over was the address book. Unfortunately they had trouble reading parts of the hard drive so I don't particularly want it installed.  Oh and to cap it off, my modem died at the same time. Still can't figure out if the modem burned out the computer or vice versa or if it really was just coincidence.

Most likely the modem was fried by the motherboard.  Typically when a modem burns out directly it is due to a power surge along the incoming telephone line, and will usually succeed in burning out the modem (thus breaking the connection) before the power surge can damage the motherboard.

(Assumes modem is not built onto the motherboard)

And, according to the tech, there's a shortage of good quality capacitators. He says he rebuilt one in his spare time over a period of months but he can't find any quality caps to do so with all the other old machines that come through the shop.

Had he said that he would slowly fix mine and donate it to the schools here, I would have been delighted. As I imagine many others would. But without the parts, it's not possible.

CL2112, thanks for the info. Upgraded the surge protector as well. It was an external DSL modem which you can't buy a new one of, you have to get one that has the router as well, even though the router I had was of better quality.

Of course I still want to listen to music so another tech call tomorrow.




wkdshadow -> RE: Computer crashed! Someone please help (2/10/2008 7:27:51 PM)

Replacement caps are actually easy to find, provided you know where to look. Mouser is a good source of components

http://www.mouser.com/Search/Refine.aspx?FS=TRUE&Ntt=*Low*+*ESR*+*electrolytic*&Ne=688640&N=2203862+4294921703+1323038&Ntx=mode%2bmatchall&Ns=P_SField&OriginalKeyword=Low+ESR+electrolytic&Ntk=Mouser_Wildcards

Edit: you're actually lucky all you fried is the modem. I've had customers come into the shop that I was working at, where the mobo took out every peripheral with it. The worst was some manufacturing plant where the caps foil went into a dead short, and took out the whole assembly line(controlled over rs232) with it.

If the budget will permit, spend the $75 or so and get a decent battery backup (UPS) -- Tripp-Lite or APC.

Brown-outs can be more damaging than power-surges, and a surge-protector does not guard against them.

Electrical devices (including PC power supplies) pull power at a constant wattage (volts x amperage). When a brown-out occurs, the voltage drops, and the device will pull considerably more amperage as a consequence--occasionally with damaging effect.

Putting a reliable battery between your PC and the wall socket will keep constant voltage and constant current flowing to your PC--your computer electronics will last much longer with a UPS protecting them.




wkdshadow -> RE: Computer crashed! Someone please help (2/10/2008 8:02:15 PM)

Also, ripple current and brownouts themselves cause surges. Induction coils don't behave well when they're being fed out of spec. And again CL is correct, a UPS is a much better way to go, because any ripple or surges are absorbed by the battery bank. Power strips and most "surge suppressors" only take away 3 to 10% ripple current in the line. Any modern switching powersupply can handle that variance anyway. If the suppressor isn't heavy enough to use as a weapon, it's not sufficient for a true surge.




ghitaPVH -> RE: Computer crashed! Someone please help (2/11/2008 7:57:18 AM)

OK.....Heres the computer update for the morning.

I tried first to just use the new profile that windows had created for me, and just transfer all of my documents, settings, favorites, and such over to the new profile. I was able to retrieve everything except for outlook express, I lost all 4 of my families adress books, and every email that was in our inboxes adn saved in folders. Unfortunantly for us alot of those emails were very imoprtant and held information on my husbands business and the like. So..I tried the retore option that so many of you suggested. I have no tried 4 different times to restore, each time going back to an earlier and earlier date, with no luck. The profile is still screwed up and not working correctly. So I would click "undo my last restoration" and it would come back to the profile windows created. Which works fine, it just doesnt have my adress books and such. The last time I restored, I went into my emails, and downloaded my adressbook and the important emails to a CD. Then after undoing the restoration, I tried to import the saved address books off the CD but it wont accept them. I am going to try one last thing. I am going to do another system restore to go back and look at the emails and address book, and try to actually email the messages and addresses to myself, then undo the restore, then open the email. Hopefully that will work and things will be back to normal....for now.

The funny thing about all this, is just two days ago P and I were sitting around thinking about upgrading the memory and graphics of this system. We may just decide to build an entirely new computer instead of fixing all the parts of this one. I have now gone through and burnt copies of all my documents and pictures so no matter what happenes this time I havent lost them.

When a computer is more than a couple years old, it rarely makes sense to upgrade piecemeal. I have generally found that it's a better use of dollars and cents to buy as much new PC as you can afford up front, so that you'll get more years of useful life out of it. What seems like overkill now will be nicely sized four and five years down the road, and the savings comes from not having had to buy or upgrade in that time.




ghitaPVH -> RE: Computer crashed! Someone please help (2/11/2008 8:18:45 AM)

This system is a Dell 4600i, and from my recolection its about 6 years old. Maybe 5...  Over the past few years we have begun doing more and more in the way of images and such. I now run a small website for my husband, it actually makes us a few extra hundred a month, but the software I use for it, and the amount of images Ive added lately has begun to really slow the system down. Ive still got plenty of harddrive space (except for the new problems of it being damaged or something), but I do think I need to get something with a bit more memory. I dont know, Ill have to do some research. Unfortunantly its rather important right now that we actually have a computer, but hopefully it wont have to be too big of an expense to get what we need. I do agree that there is no point going the cheap route now if its not really what we need anyway and will just have to pay more later..,...




camille65 -> RE: Computer crashed! Someone please help (2/11/2008 8:32:51 AM)

Dell has a free online data back up system.https://www.delldatasafe.com/login.aspx I just cmailed it to you, but then thought others may want to know about it too.I'm so sorry you lost everything [&:]. Charter cable deleted my entire freakin account a few months ago and I lost years worth of email/address book info. http://www.foxnews.com/story/0,2933,325338,00.html

Don't even bother trying to upgrade, then. The only thing you plausibly can upgrade/replace is the hard drive, and possibly the video card. The motherboard is not likely to accept current CPU and RAM configurations (and Dell is worthless when it comes to getting upgrade parts for their older models).




DesFIP -> RE: Computer crashed! Someone please help (2/11/2008 11:09:10 AM)

I got the APC. Now I have to find the restart button which being black on black, I'm going to need a flashlight for.

The tech said all he's finding are cheap caps which don't last. He said Dells are showing up in the shop in huge numbers for relatively new machines because of that.




seeksfemslave -> RE: Computer crashed! Someone please help (2/11/2008 1:14:19 PM)

No help 'cos I dont know anything about PC Software/Hardware
but
capacitators should be spelt  capacitors and Electrolytic ones have always been a weak link in the hardware.
In the old days they used to dry out ie the electrolyte, a paste I believe, used to go solid.

Using DOS, does anyone know how to change file 'permissions' or can that be done using WindowsXP




wkdshadow -> RE: Computer crashed! Someone please help (2/11/2008 1:32:52 PM)

To change basic attributes in DOS, use the "attrib" command. "attrib /?" will give you a breakdown of how to use the command. For ACLs(probably not what you're looking for), use "cacls". And yeah, caps have always had problems, but properly manufactured caps of current generation are pretty reliable.

If you want to change the permissions through windows, just right click on the file(s) and goto "properties".

As for the address books, if they're failing to import they may be corrupted. CRC checks should have failed, but, I've seen it happen. Your email may still be on the pop3 server. When you setup outlook express again, it may pull off all those emails from the server, but I believe the default behavior for express is to retardedly delete them from the pop3 server. One thing you might wanna try is calling your ISP, explaining your situation, and asking if they keep backups. I'm sure they've got atleast some of your emails on tapebackup or a SAN.
