Re: Dell 2405FPW intermittent power fault
I'll likely order caps while I'm in the guts, but don't want to just shotgun parts at it without knowing what's really failed/failing.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Dell 2405FPW intermittent power fault
Apologies for necro-ing this thread, but was there ever a solution found? My 2405FPW is doing the self power-off/power-on thing as well.
Any pics of which board is which I can use to try the heat test? My issue definitely seems to be temperature related as it happens a lot more often during the day than at night.
Thx!

Re: lenovo t430 no backlight
Not quite the same issue with my daughter's T430. Backlight works during POST and for all BIOS setup stuff, but then shuts off after the Windows splash screen is displayed.
Booted a live CD (Kubuntu if it matters) and it seemed to work for the 30 mins or so I had it running.
Yesterday, I had it sitting in BIOS setup and got pulled away for a couple hours and came back to find the backlight turning on and off every few minutes. Planning on tearing it down tomorrow to check all the fuses etc... Any other things I should check...

Re: Abit AI7....
Not a single minidump file on my entire machine. Settings say it should be in %systemroot%/minidump.
When the machine BSODs, it locks up hard and requires a power-off reset.. Expecting my caps from Mouser today so we'll see what recapping does...

Re: Abit AI7....
Not a heat issue unless Motherboard Monitor and the BIOS's System Health info are lying to me. I've never seen any sensor temp top 42C, even when rendering or playing games. Machine was overclocked until the problems started (p4 2.8GHz @ 3.15Ghz - no voltage increases required) when I set it back to 'stock' and it's been there since.
I'll look for the minidump file.. One of my other machines puts it in C:\Documents and Settings\[username]\Local Settings\Temp\[some_odd_named_folder]\
so I'll look there...

Re: Abit AI7....
No such animal on my machine. Most BSODs totally hang the system and require a power-off restart - can't even mash the reset button to get it to reboot....

Re: Abit AI7....
Well crap.. The BSODs are back.. Different stop code now tho.. 0x0000008E. Seems to be something with the Nvidia DLLs, but got one this morning referencing the page fault again..
WTF? It ran for a couple weeks with no problems and now it's acting up again..
memtest still shows no errors even after letting it run overnight, the WD diags say both drives are good but here's a nifty twist. The brand new 80G drive is showing 80k of bad sectors in the same exact spot as the failed 40G drive.
BIOS hiccups?? Didn't have time...

Re: Abit AI7....
Nope. Dimension 4100. Locks up after about an hour of use - gotta be hardware because it's only got a fresh install of Win2k server on it.
BTW: For anyone interested, the WD drive shows up as "Limited Warrany Not Available". Must've been an OEM (i.e non-boxed) drive....

Re: Abit AI7....
No, I ran memtest right off the floppy. Haven't had any errors since the 1st time through on this AI7 or the borrowed MSI board I ran over the last weekend.
Drive never made a sound and a surface scan shows no bad sectors at all. WD tech support thinks the controller board on the drive took a dump. Not sure if the drive is still under warranty or not. Gotta dig up the receipt for it and find out.
I've got a couple days on the new drive without a crash and was able to burn a bunch of video to DVD last night without a...

Re: Abit AI7....
OK, figured it out. Almost every cap on the AI7 is Rubycon so I'm satisfied it's not the mobo. Memory tests fine on another machine I borrowed for the weekend and swapping video cards still showed the problem. Only thing left was the HD. It's a Western Digital WD400BB 40 gigger and WD's diag software showed it as failing the S.M.A.R.T test. I backed everything up and let the WD software do what it wanted to do to the drive and it failed every test thrown at it. Picked up an 80g SATA drive and bolted it in. Running perfectly now, even at tasks where I could get it...

Re: Abit AI7....
yeah, took a look at the caps on the board. Didn't see any obvious bad ones and it looks like about half of them are Rubycons (Well, they're purple like the Rubys) but I can't see for sure unless I pull the board out. Funny, but it's been running fine thus far today.
I did swap the PSU a couple weeks ago but the problems persisted so I put the original back.
Now I'm wondering if perhaps my system drive (WD ATA133 40G 7200 rpm) is the problem. With the page fault errors it's something between the memory and the drive. Frustrating....

Re: Abit AI7....
OK, now this is wierd.. After I posted my initial message, I went to the garage to work on my ATV for a bit (Replacing the clutch if anyone cares. heheh) and then came back in to the office to see how memtest was going. For giggles, I restarted the tests and sat there for a minute watching the results. Not a single error as it completed test 4. I left it alone to finish up my work in the garage and when I came back in around 12:30am, it had finished the 1st round of tests and was starting test 2. STILL no errors... WTF??
I hate to just shotgun parts...

Abit AI7....
Bought an Abit AI7 early last year and built up a new machine for myself. A couple months ago it started locking up and would throw the occasional BSOD. I figured with all the installing/uninstalling of crap I do, the registry was baked so I backed up all the good porn.. er.. I mean my documents <grin> and formatted the drive and started over.
Took a few evenings to get it all put back together and re-import all my mail from the archive files and all was peachy for about a month when it started acting up again. Now it's tossing 2 BSODs.. PAGE_FAULT_IN_NON-PAGED-AREA with...

Re: Resurrection weekend...
Oops.. Guess I should have popped back in here sooner. No way to tell waht the component number is/was. I tossed the board a couple weeks ago...

Re: Resurrection weekend...
OK, did some more poking and prodding with my meter and found what I believe to be a bad VRM. Unfortunately I can't make out any nomenclature on the thing so have no clue what part I might be able to replace it with... Oh well, 2/3 is still a 67% success rate.. The "saved" machines are rock-solid with over 72 hours of Prime 95 time on each of them.
$35 in caps, a few hours of my time and a couple Newcastle Brown Ales made it all worthwhile.

Re: Resurrection weekend...
OK, armed with that bit of knowledge, again, how does one check VRMs or Mosfets for shorts/opens??

Re: Resurrection weekend...
OK, I guess the VRM isn't what I thought it was.. Can someone post or send me a pic with that I should be looking for (and how to check for shorts/opens??)
This has become sort of a personal challenge now..

Re: Resurrection weekend...
Pardon my ignorance, but I just walked in from another 13 hour day and my brain is fried... What's a VRM and what do they look like? Voltage regulator? I know what those are... That'd be nice if that's what it is..
Thx!

Anyone ever tackled a Dell Dimension 4100??
Got the machine as a freebie from my Bro-in-law. 1g Ram, GeForce 3 and a PIII-1Ghz.. Started "singing" last night and locks up after about two hours of operation so I figured I'd have a go at it and see if I can get a couple more years out of it..
