Craziest Hardware Issue Ever

I've been building my own computers since I was 12 (21 now) and I have never seen anything like this one.

First the specs:
Chaintech 7nif2 matx mobo
Mobile XP 2400+ 35Watt
512mb PC3200 Corsair Value Select RAM CAS 2.5


Ok, about 2 months ago I had been wanting a HTPC/Gaming Server, so while building a computer for someone else, I tagged on the CPU and mobo to his order and didn't charge anything for putting his together. Fry's had the RAM for like $30 AMIR so I thought I had my computer for dirt cheap. I put it together, had to pin mod it to get the voltage and multiplier right (defaults to like a multiplier of 6 and 1.5ish volts). After set the pin mods to 1.35V and a multiplier of 13 for the 2400+ (being an HTPC I wanted it to be quiet, hence the lack of OC'ing) Ran fine for a couple of weeks, but it seemed like the hard drive was dying. Files corrupting here and there. No huge deal, all my stuff was on an external one anyway and the one in it was a 3 year old white label maxtor; I figured I'd just ride it out and replace it. Well, finally Windows corrupted to where it wouldn't boot anymore, and that's when it all started getting wierd.

I swapped out HDs and tried to reinstall windows. I'd get past the quick format and it would start copying files and then say something to the effect of "cannot read file (fill in the blank), possibly a bad CD. X to retry, Y to ignore, Z to abort" So I'd put in a different XP CD and get the same error. I tried this at least a dozen different times as the "corrupted files" were different each time and totally random. Then on some off chance I decided to do a full format instead of a quick one. While formatting it came up an error saying that the HD partition was bad and to install it on a different drive. So I swapped it out for another drive that I know is fine and it does the same thing.

A friend suggested that I test out the RAM with memtest and sure enough it's got errors galore. Well now I've solved all the worlds problems I thought. Grass will be that much greener and no more wars and... you get the idea. But alas, NOPE. I swapped it out with my 512 stick of CAS 2 XMS from my gaming rig and reran memtest to be sure. No errors this time. Great! I thought and proceeded to install windows. Same exact errors.

Also I have a DVD norton ghost img of a preinstall of windows that I use with my gaming rig. So I put that in and cloned it to the HD and everything seemed to work. For about 4 or 5 reboots, then stuff got so corrupted again that it wouldn't boot.

Recapping, I've tried:

about 4-5 windows CDs (all of which have tested out fine in other systems)
3 CD ROM drives
2 different PSU's (both of which are decent PSU's and tested out fine in other systems)
2 sticks of RAM (one of which tests out and is known to work in my gaming rig)
a img of a windows install cloned onto the hard drive
3 different hard drives
4 different IDE cables

I am not OC'ing at all. My bios shows my Vcore to be 1.34
I have no PCI slots installed
I am using the onboard video
I have turned off the onboard sound/LAN
Cooling is not an issue


That's about all I can think of. Any ideas/suggestions would be appreciated. Also, does anyone know how Corsair's warrenty/RMA department is, as it looks like I'll be talking to them tomorrow? I really don't want to RMA the mobo to newegg, (they are a pain when it comes to RMA'ing stuff) but it's looking more and more like that's exactly what I'm going to have to do.

BTW, here's my gaming rig for parts that I can swap with my HTPC to diagnose stuff:
XP 2400+ Mobile
Gigabyte GA-7N400 Pro 2
512mb Corsair XMS PC 3200 CAS 2
Radeon 9500 non pro (which soft modded into a 9700 pro ;) )
Antec 350w PSU
WD 10k 35gb HD (also of which I am quite proud of)

Thanks again for any help

Well I don't know if you have tried increasing the voltage ont he RAM. try 2.7 volts and see if that will improve these errors that you're getting. That is the only thing that I assume you haven't tried. It seems like you have tried everything else. GOod luck trying that!

Thanks for the input. I haven't tried bumping the voltage yet, but that shouldn't be a problem with the RAM out of my gaming rig. I tested it in the HTPC using memtest without a single error. So bumping the voltage might save me a RMA to crucial, I don't think it's the key to getting windows on this thing.

Maybe I have the first mobo with built in AI and this is it's way of telling me to install slackware on it.

Voltage could be the problem but my real question has nothing todo with your problem . i would like to know why your ghosting way back when it was ok but why now

I'm not sure I understand your question. What do you mean by "ghosting way back when it was ok"?

Edit: oh, sry, i'm stupid, norton ghost. I have a DVD with a windows preinstall with drivers and such for my gaming rig. I have a 10k rpm sata drive that I boot off of, and no floppy drive to install the drivers off of during the windows install. So I installed windows on an IDE drive, loaded on all my drivers, customized windows how I like it, grabbed all the windows updates, loaded on Zone Alarm, Opera, and a few more things, and burned it all to a DVD img. So now when I want to reinstall windows on my gaming rig, I put in the DVD and 10 mins later I have a fresh install with service packs, windows updates, zone alarm, and the like. Very handy as I generally reinstall windows before every major LAN that I go to.

I tested it once on my htpc because it was a way to get windows on the drive without going through the windows install which wasn't working.

hi,
are you getting any errors (like ide ones) in your event viewer logs? i've seen (only one or twice) the bridge chip go bad and corrupt the hd data. but it usually gave errors in the event logs.
bummer if this is the case, it's a mb rma.

Well, the thing is off to newegg, and I am $8 poorer. (dumb newegg rma) I didn't even think of checking the event log. Great idea though. Should have done that, but afterall, it did only boot into windows for about 3 times. I guess we'll find out in a week if that really was the problem.

I had tested my ram with memtest also and it was fine. Went through all the tests really well. But when I bumped up the voltage, windows was running fine. I would get strange reboots for no reason. Well hopefully when you get it back it runs fine.

BIOS virus...happened to me with an MSI K7 series board. Tried to install Windows 98SE, and that didn't even work. Couldn't even swap a working HDD with OS. It wouldn't even boot. Its extremely uncommon, but of course it would happen to me.

Got a new mobo back from Newegg a couple of days ago. Everything seems to be working fine. The new mobo still doesn't like the bad ram, so I'm running some different RAM right now. I'm going to RMA the bad RAM as soon as finals are over this week and I have time to think. Mobo seems to like my new $200 vanilla 6800 from compusa, that unlocked and is now running at 6800 GT speeds. :cool:

There is one thing that's not making sense to me. When using the onboard video the chip claims 32mb of your main RAM. With this setup you can't take the RAM past pc2700 (a.k.a.fsb of 166) speeds. Now that I've sold my other gaming system I've got a AGP video card in this one. (6800) Still however when I set my FSB above 166 it will not boot.

Oh well, thanks for the help guys. It seems it was a buggy mobo after all.

You do realize that the CPU requires a certain minimum voltage to operate properly, right? Both the apparent HD and CD data-corruption could easily be caused by undervolting the CPU. You can underclock + undervolt, but I wouldn't recommend undervolting by that much at stock speeds. That's just asking for trouble. I would crank the voltage back up, run the system at stock, re-format/zero-wipe the HD, and attempt a re-install.

If you've done any BIOS flashes since undervolting, I would possibly re-flash at stock as well, if the re-install again fails.

All completely consistent symptoms of undervolting. (Same result as OC'ing without giving enough volts - data corruption.)

Oops, nevermind, I missed that this was an old thread. Sorry.
