420Pro Leaking Caps

I have a K7N 420Pro board, purchased 1/31/02. First time fired up was 3/6/02 Played with it for 3 or 4 days and had some BLUE SCREEN issues with it. I didn't have time to play with it so it sat until July which at that time I dowmloaded new Drivers for Radeon, Audigy, and Logitech which for the most part fixed alot of rhe problems I had. This was my first computer build and its been a learning exp. and still on going thanks to forums like this one.
My main problem that I jst became aware of yesterday are the caps that I have that are leaking at the tops of the cans and the ones that appear bulged. I searched the forum for info and found only one article posted with a story about the industry dilemma, it had the same info as one I had read some time earlier.
It seems that Abit was the only MB company to acknowledge the problem. Has there been any updates to this and does MSI plan to rectify this problem with its customers or will I have to change them out myself after I complete my next build (which is in progress, motherboard discision pending) Please let me know what info or recommendation you may have about this Capacitor. Thanks again for everyones help! Bill

Hi,
Replacing capacitors is a relatively easy job - if'n you're handy with a soldering iron, you could probably do it yourself! You certainly don't need to be an MSI tech!
If your board's still under warranty then RMA - if not, then ask your local store what guarantees he gives if things go wrong when changing them!
If he's offered to change them for you, then this would seem to suggest that he's reasonably confident he's up to the task - then again......you never know!

IMac G5 (no iSight) fans running full speed always

Hi,
The processor usage is relatively low (like 10%) but the fans are full speed at all times from the second the power comes on. I imagine there isa problem with the mother board? I've tried resetting all the SMC stuff, no effect.
Any ideas?
Is this something Apple Stores will charge to fix?
Thanks

It could be either faulty, leaking caps, or a failing power supply unit. Yes, Apple will charge since you are long out of warranty. You can open the machine and check the caps yourself, they look like little soda cans, and their tops should be perfectly flat and there should be no exudate.
Let us know what you find,

My iMac is making a louder that usual sound when in use - any suggestions to get it to chill out a bit?!

It's a low whirring, I'm sure it's louder than it used to be and it definitely gets louder the more windows I have open, or applications are running, iTunes with Photoshop and Safari etc. causes it to get much louder. It's not the actual fan as far as I can tell, the other day I put it to sleep and it instead froze and the fan was really loud in that case and I just had to turn it off at the back.
I tried repairing the disk permissions, it's made no difference. I can't see anything out of place it Activity Monitor but I might be wrong about that.
Is it a case of the Mac getting too hot, or just that it's nearly 6 years old?!
Any suggestions would be great, thanks.

First, make sure that all your air vents are free of dust and lint.
Then,try http://support.apple.com/kb/HT1436 Resetting SMU
After that, if you do not have an iSight, open the back and look for bulging or leaking caps (the little soda can). It's likely that either some caps are bad or your power supply unit is failing. Go to User>Applications>Utilities>Console and type in maximum temperature in the little box at the top right of Console. If you see any heat messages, then your problem is likely what I suggested.

IMac overheating and unusually loud

For about a week, my iMac has been strangely overheating and loud. The only reason for this I can think of is that I recently moved my iMac to a different location, but still there is really no reason for this to be happening. My mac has adequate space where it is right now, and I'm not doing anything on the computer to make this happen. Before I moved my mac, this never happened. It was always silent (except maybe when I was downloading something or watching videos) and really cool even when the computer was running. Now, even when my mac is sleeping, it is warm and when it's running, it is extremely hot. What is causing this? I was thinking that where the iMac was plugged in may have an effect, but that's just a what-if. Help!

Try resetting the SMU, if that doesn't work you probably have some swollen or leaking capacitors. If you can, take the back off and check for swelling or leaking caps, their tops should be absolutely flat.

Imac G5 shutting down of its own accord

now I know the first thing you will say is check your system settings but I have, have taken off all energy saving functions etc.
I switch on my machine and read emails etc, sometimes open Quark/Photoshop ready to start work, then go away for an hour (school run etc), when I come back it has shut down, I have not seen it doing it so can't say if it comes up with an error message but when I restart I get no error messages at all, and all works fine, have no other problems. It has only started doing it over the last week and I'm stuck as to what to do to fix the problem can anyone help?
Cheers

If, in Console, you see messages about maximum temperature exceeded for 30 seconds, you have a thermal problem, either a failing Power Supply Unit, dried thermal paste, bulging or leaking caps or a bad connection.
Plenty of choices, you can open your machine and look to see if any of the caps is leaking or swollen, you can also clean all the dust out of the machine and make sure the fans and air vents are clean.
Then reset your SMU:
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Press and hold the power button for 5 seconds.
4. Release the power button.
5. Attach the computers power cable.
6. Press the power button to turn on the computer.
After that, reset the PRAM and please post back and let us know how things went.
It would also help if you would list the exact model of G5 iMac you have.

SE/30 refusing to startup

I recently retrieved my beloved old SE/30 from 12 years in (safe) storage. Was working fine when I packed it away and is in great condition - except it won't boot.
Symptoms: Bright, well-adjusted raster and moving cursor; no startup tone, no disk icon, goes no further in boot process. If I insert a disk, nothing happens. Doesn't seem to get far enough to respond to keyboard commands either, so I'm really stuck. 40MB HDD spins up, as does the external (whopping!) 1GB SCSI drive. Tried internal 40MB HDD thru external SCSI port = no go. (Only difference was the cursor wouldn't move.)
With _no_ HDD attached and nothing in floppy drive, I get same symptoms (above).
"Programmers switch" does't help; one blanks the screen for an instant and returns it to same state, the other produces 000000F over 0000013 (which only means "don't do that again" near as I can tell).
I found leaking caps and replaced all caps on logic board (incl. C11, the 220mfd to nowhere), new battery, got all drives working, cleaned/reseated all chips/connectors. All that = no change.
I have Larry Pina's Dead Mac Scrolls, all 8 pages of the SE/30's schematics, and a growing list of 20+ SE/30 web sites. Hoping the gurus here might have a suggestion or offer the clue I can't seem to find anywhere else. Feels like losing an old friend…..
Are the Bourns RC network chips (marked 115-0002 C 558 8943B) at RP2, RP3, RP10 critical to startup as some suggest? Are they the next suspects?
Thanks,
Mike

Hi Jim, thanks for the kind words and response.
I'm in N. Cal. near Sacramento.
Another SE/30 would be a great help to be sure. I suppose I could dust-off my old Performa 6300, it has an external SCSI II that _might_ read the old MFS format. But - no display! No shortage of cables/adapters here, I have an old VGA - hmmm.....
I have 800K floppy drives, but only the one 1.44, and two 128K Macs (turned 512s) that are no help with the SE/30. I also have a SCSI Zip drive (and disks) packed with the SE/30 that might be handy eventually.
But I don't think I'm getting far enough in the boot process to blame drives yet. With no HDD and nothing in floppy drive, I should get a tone and disk icon/question mark, no? Machine has 5MB RAM; I tried removing the four 1MB SIMMs from bank 1 leaving four original 128s in bank 2, reversed banks, tried four 1MBs in each bank, no help (no other way to test RAM). Bad RAM would produce a sad Mac, right? "Mo" (short for Maureen) also has a Diimo board, with/without = no change. Even removed the ROM, result was horizontal bars.
This machine was my workhorse for many years, was always solid as a rock (menubar is burned-in to CRT).
If the ROM chip somehow went bad, would I still get a solid screen? And how is the mouse/cursor working without any OS/driver?? Then there are the Bourns..... (BTW, I have Pina's book because I used it to troubleshoot Macs back in the day.)
Assuming RAM passes, what's the next step in boot process?
Thanks again - I'm stumped.

Since loading IOS6.1 on my 4 it is constantly shutting down of its own accord

IMac G5 17" 1.6 GHz shuts down by itself

I bought an iMac G5 17" 1.6 GHz about a two weeks ago. There was a capacitor in the power supply went bad. The power supply has been fixed. But It would give itself a rude shut down about after thirty minutes of use. Any help?

It could be bad caps in the power supply, it could also be bad caps on the logic board. Open the back and inspect the board for swollen or leaking caps. You might also want to call the person who "fixed" it and ask them to do a proper job.

EMac shuts down when bumped.

I have an eMac 1.42 GHz PowerPC G$ w/ 256 RAM, OS 10.4. The machine runs quite fine most of the time (i'm using it right now..); but it shuts down, hard down, when it is bumped or knocked. It is in a school, on a desk, and schoolbooks get put down on the bench next to it; or a child will lean his/her elbows on it and bang, down it goes. I have had a technically inclined person investigate inside, to a reasonable extent, and everything seems to be screwed down tight or plugged in tight or inserted in the right places and latched. Still the machine shuts down. It will do this with peripherals attached or not (such as keyboard...) It will usually restart when the on button is pushed, but I need to have it running, not restarting all the time. To the best of my knowledge it is not under warranty for burst capacitors, according to the serial number. (It does not seem to have any burst or leaking caps anyway...) It is not under any type of warranty, and I can't really afford a significant amount of money to repair the thing. It's getting to the point where it's more fun to whap the left side with my fist and watch it shut down, than to use it. This, however, is counterproductive. I am open to suggestions and hope for the best.

I have tried several different power cords. Same result. However, I will check inside the case to look for loose contacts at the power-in juncture. Nothing was evident previously, on an inspection. A detailed and closer look is definitely called for. I had been thinking maybe the collar around the CRT tube, or something; though I don't exactly know how to go testing that; and it rather frightens me to try to discharge one of those things...

Como regresar a la pantalla a la normalidad? How returning to the screen to normal?

I have a problem with Mozilla Firefox which is that the screen is moved to the right (if you see it defrente) and whether or whether it should remain full screen to view all content. I would appreciate if you help me find a solution.

Did you use a wireless keyboard to reset the PRAM? If you have access to a wired one, please use that. Have you opened the back to check for swollen or leaking caps? Is all the dust on the fans and air vents blown out? Check the [LEDs|http://support.apple.com/kb/HT2831] as well.
Try booting from your install disc and using Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.

Power On Problem?

Hello again.A friend has a 17" Power PC iMac G5.Pressing the power button would not start it.I tried unplugging and re-plugging,And pressing the button again,and nothing.Finally,after more pressing,it started up.
After a minute or two,it shut down on its own.
I did this routine 5 or 6 times,pressing the button with no response,unplugging and re-plugging,then suddenly it would power on for a few minutes,then shut down suddenly.
The last time,I tried booting it in safe mode,which it did,but before the fans could die down, it shut down again.
Any thoughts would be much appreciated,thanks.
John

Hi again...well,I studied those pages on jimwarholics site and figured I could follow directions and do those repairs if needed.Packed up my buds Mac and brought it home to work on.Opened it up and to my delight,found two bulging and 4 leaking capacitors.Unfortunately,that repair is a bit out of my league.I think.
Anyway,I went through the steps in this artical:
http://support.apple.com/kb/HT2173
Pressing the internal power button,I was able to get to the desktop,but after a minute or two it would spontaneously shut down every time.
So,I'm not sure if the leaking caps are muddying the waters here.
Can't tell if it's the power supply,the logic board or the capacitors.Or any combo of the above.Any thoughts?
Thanks again.

Dell 690 Capacitor Blown -- Can I fix it?

I have a Precision 690 BIOS A08 that I am upgrading for a customer. It had a Dual Core and 4 Gig RAM. It is a MY171 board and I got 2 quad cores and 16GB ram for it. We were prepping it for Win 2008 or 2012.
I put the processors in it and the memory in it and it posted, and I was like OK, this is going well. I went in the BIOS and saw both Quad cores and all 8 2GB sticks of memory.
Booted to a USB stick to run Memtest and noticed only 8GB of RAM. Shut down pulled the battery and held the power button for 30 seconds, then left the battery out for 30 min.
Restarted and it complained about incompatible processor. So decided to pull the quads and go back to the original dual core and troubleshoot the dram. Booted up still have 1/2 the RAM. Went to pull the ram and and started looking at the dust that was there when I was installing the ram. I had blown the box out well just recently with a compressor. So I was surprised that this dust had not been blown out.
Pulled the sticks and noticed that possibly some dust might be in a few slots, and figured I'd pull everything but the first two sticks and start looking for a bad stick. Then I saw the Blown Capacitor that looks like it might be supplying power to "some" of the ram slots.
The box runs OK, if I had not noticed the RAM being off, I wouldn't know from the way it was running. Before I noticed the RAM issue I had created a RAID array.
Has anybody had experience with these Caps blowing like this?
How about repaired one?
It seems like it must be this one CAP because the box is running too well for anything else. It looks like this cap is part of a pair that may feed 1/2 of the ram slots.
www.turbonet.biz/.../P1000103.JPG

The capacitor is bad so you RIP it out(By pulling Gently so that the leads come out from the can) and then desolder each pin (One at a time) using mostly flux then vacuum out the hole with a solder sucker then put a new cap in. Trying to desolder a cap with the can intact will sink the heat away and cause you to pull out the thru hole leaving you with no connection and possibly a bad board. You also want to clean up the potty mess that the leaking cap left behind with 99 percent isopropl alchohol on quetip swabs.

X48c startup problem

Hi Everyone,
I'm having a problem with my x48c. It starts and shuts down within a few seconds. I have tried everything including a new power supply and it still does it. I've tried disconnecting everything too. Just started happening. If I hit the restart button right after I hit the on button, the computer starts and runs fine all day long. I am using it right now to post this message. Could it be a bad cmos battery?

It could be the battery, it could also be bad connections from your case on/off and reset buttons to the board.
Maybe do a test by removing the case connections and starting the PC by shorting the on/off pins with a flat screwdriver tip and see if that makes a difference.
Other thoughts are ageing/failing capacitors. How old is your PSU ? Can you test with another known good PSU.
Do a visual inspection of the MB for any bulging or leaking caps.

My games come up on the screen but then pop off

I can bring up various games on my Iphone but they immediately click off. What do I need to do to get these games to stay on the screen.

That sounds like the classic bad capacitor or failing power supply symptoms to me. You don't say which version of the iMac G5 you have, but early ones were especially prone to bulging/bursting capacitor problems on both the logic board and in the power supply. If you know how to open the iMac, do so and inspect the board for bulging or leaking caps. There are folks out there (myself included) that have sucessfully replaced the capcitors on these Macs.
If the board looks good, it may be the power supply. These are a little tricker to open, so be warned. Same problem in a PSU (bad caps)
The shut down issue is what prompts me to believe your machine is suffering from this problem. Normally a failed hard drive would just hang at the gray apple logo, or get stuck on the blue screen, or give you a flashing ? mark at startup; it wouldn't shut the Mac off.
Good luck!

Imac random shut off

I have a g5 imac that just started shutting itself off. Temp and fan speeds are normal. I have reset the SMU and it's still doing it. I found this in the system log-AppleSMU -- shutdown cause = -110. Anyone know what this means?
Thanks

Shutdown cause 110 is thermally related, it could be a failing power supply, a bad connection or not enough thermal paste. Bad capacitors will also produce the same result. Open your iMac (as long as it's not an iSight) and check to see if there are any bulging or leaking caps.
