    Default Weirdest Problem Ever? EP45UD3R last attempt getting help before RMA...or exorcism

    Disclaimer: I hope the "RMA" in the title does not flag this for moderation in light of the sticky topic on this board. This post is not about RMA'ing.
    __________________________________________________ __________________________________________________ _________________________________________________

    I don't know computers as well as most on these boards. Nevertheless, I do not hesitate labeling this issue as bizarre and indeed perhaps the most bizarre I've ever heard of.

    Succinctly, it can be summarized as an issue of random restarts. The computer abruptly restarts. Blank screen, no BSOD. It's been going on for months. People on other boards didn't believe me that it was random, so myself and some friends (as we often do) decided to make it a point. We recorded processor load, all temperatures available by the sensors in the machine, voltages, hard drive rpm, what have you. It correlates with none of them. And I'm not just saying that, the p values were >0.05, indeed the lowest was 0.22. Yeah, it's weird I made that measurement. But that should convey the degree of frustration. And further, the restarts are random. Not slang random, but mathematically random. The only nonrandom part is that as time goes on, the average time until the next restart decreases along a logistic curve. Component failure? Perhaps.

    A computer repair guy, however, suggested changing the hard drive...perhaps it was feeding the mobo irregular voltages, or somesuch. So I did. New terabyte drive. And it worked! for 48 hours at least, then it restarted. And again. And again. And lo and behold, the average time was bumped back up the curve and was restarting its slow descent into "this damn computer can't run continuously for more than a half hour!"

    What else have I tried? Piecewise removal of RAM, DVD-RW, HDD, GPU, all USB components. Fooled around with the BIOS numerous times, which had no effect. I even posted here, got some great suggestions. Flashed the BIOS three times. Installed Win XP x64, x32, Vista, Fedora, Ubuntu and even tried Knoppix. None had any effect. However, the system can run continuously when one uses the Ubuntu livedisk. At least, it didn't crash the whole time I was testing it. Weirdly, when an OS is installed on the HDD, the DVD-RW is reclassified (in windows) as a DVD-RAM and (on all OS's) ceases to operate. Until I replaced the HDD. Now it does. But for how long?

    So, does anyone have any more diagnostic suggestions before I replace the PSU or the motherboard? Those are the only two options left at this point, and really, they were the most likely culprits all along, I just didn't want to admit it. Here's some (current) data:

    OS: Windows XP x64

    Mobo: EP45-UD3R

    BIOS: Version F6

    Processor: Intel Core 2 Duo E8400 Wolfdale 3.0Ghz (which my computer misinterprets as P3 Xeons, for some reason)

    RAM: 8Gb G.SKILL 240-Pin DDR2 SDRAM 800

    Power Supply: Rosewill RX850-S-B 850 watt

    GFx: PNY GeForce 9800 GTX+ (VCG98GTXPXPB)

    DVD-RW: LITE-ON 20x DVD-RW

    Hard Drive: Seagate SATA 3.5" Barracuda 1Tb

    Any ideas? My previous posts are all located in:

    You'll be fine about having RMA in the title. Lsdmeasap (Moderator) and others are more than pleased to help and advise with RMA advice. The sticky is there because there have apparently been cases where this forum was used to post abusive comments and generally stir up trouble about RMA's people weren't happy with etc.

    From what you say, I'd also come to the conclusion that it's the PSU (try first) or the motherboard. That is as long as you have verified all the other components by testing them in another machine.

    I've read both your original post, and this one and can't see if you've removed the board and checked for shorts. If your case came with rubber/paper stand offs, are they fitted? It can become an intermittent problem if part of the board contacts the case, possibly due to vibration from fans and hard disks. It's obviously not shorted perminantly, or you'd probably have more severe problems.

    Being able to try a different PSU would be very useful. Can you borrow one from one of your friends? It would be a shame to buy another PSU, only to find out it's the board. If the problem still happens with the borrowed PSU, I would assume a motherboard problem, maybe a dry solder joint, or a failed component(s) (capaitor, resistor etc).

    Having been building PCs for a long time I've got a load of spares I can use to identify problems (PSUs, Motherboards of all socket types, RAM, processors etc) but I can apreciate it can be a pain in the arse if you don't have spares to hand. Definately try and get a hold of a PSU first. If you do have to buy one, may as well buy a quality one of around the same capacity. Good choices are Corsair HX and TX models, Seasonic, BFG* (*only the ES-800 which is awesome, other BFG models can be dodgy), FSP, Tagan or Zalman.

    I believe you had settings over there at that post?
    Can you copy the current setting on the motherboard to this post?
    Makes it easier to see whats about

    As its been previously indicated swap a psu to start.

    I didn't test it personally. Rather, I had someone else do the testing for me and *they* said it was "fine. it's not the power supply," but I can't be sure.

    I have friends with spare PSU's but, they're all in the 300W range, and I don't know how much of my computer I could run off that or if it would give me an accurate estimation.

    One other quick question, how much should the +12V, +5V, and Core voltages fluctuate? (what is acceptable +/- ranges?) and if they exceed that, is it the PSU or the Motherboards fault?

    Also, thanks for the quick replies!

    Sloth-

    Thanks for the suggestion, I'll try that ASAP. But I dont' know if the problem conforms to a BIOS configuration issue since it was fine for ~3 months and then began to develop the problem, without any changes (at least, changes I was aware of) to the BIOS. But I'll certainly try it.

    You should be able to power all of your PC from a really good quality 350W PSU for testing purposes. Don't run the GFX card in 3D mode though (including full screen gaming and windowed 3D). I've tried powering my system from a 350W FSP while trying to see if my old Hyper PSU was dead (it was), all went well.

    Again, if you have a spare GFX card you can swap in (preferably one that draws all its power from the PCI-e slot, not a 6/8pin connector) it would ease stress on the borrowed PSU. I'm willing to bet your system (in 2D use) is drawing less than 300W from the business end of the PSU, even at full processor load.

    You didn't say if you've removed the board to check nothing is shorting out on the case. This isn't impossible, and can lead to the kind of problem you have.

    Default Re: Weirdest Problem Ever? EP45UD3R last attempt getting help before RMA...or exorcis

    Hi guys I am curious what brand (model number?) of case he has holding it all together? Could be a bad connector thats shorting or grounding a wire. Its happened to me!
    Also, Do you have a utility to keep your graphics card cool like Rifa tuna? (riva tuner). My geforce card runs too hot and does not regulate the fans well to control the heat in case and on card. I think its a possible reason my last board died, that and no southbrige heat sink.

    Hope you get it sorted out.
