BSOD help needed

I have a 1 year old machine I built that has operated flawlessly until the last few weeks. Now I'm getting BSOD at random times, sometimes after a few minutes of use, sometimes hours. This is a Vista 32 Home premium OS. I get messages about unexpected shutdowns listing dump files, but I don't know what to do with them. If I look at the event viewer, there are several errors listed with different sources, again, I don' t know what to do with them. I don't think its an overheating problem. All fans are working, and the Asus board monitors show cpu temp 27C, system temp 36C. When I touch various components, they are just barely warm. All trouble seemed to start after we added a wireless printer as a network printer. It occasionally seemed to cause an IP address conflict message to pop up. I changed the IP address and have not received any more of those complaints, but maybe it did something? I've also received an occasional message from Trend anti-virus saying that unexpected shutdowns could be caused by a bad update and that it has reverted to an earlier versions to control that. So if anyone has any good ideas about how to investigate this I would appreciate the help. I do have snapshot jpeg's of some of the error messages I can email. I've tried to run memtest, but it blue screened after 1.5 cycles, although no problems were noted up to then. I also ran chkdsk, but it blue screened just before completion (92% into step 5 of 5), no errors had been reported up to that point.

  1. Welcome to the forums!

    Tell us about your power supply.
  2. It sounds like a RAM issue to me. RAM problems are the most common cause of BSOD's. What are your complete system specs?
  3. ASUS P5QE mb;
    Corsair 2X2Gb DDR2-800 dual channel
    Evga GeForce 8500GT video
    Intel Core 2 Duo E8500 3.16 chip
    Antec case/ps

    Antec case -- Sonata II if I remember with their 500W earthworks supply
  5. Run memtest86+ with one stick at a time, alternating memory slots.
    Make sure your memory voltage in the bios is correct.

    New Egg item N82E16820145484

    I made a mistake; the case is a Sonata III, 500W power supply, and the video is an 8800GT card

    I can do this; last time I tried was with both sticks and it blue screened after 1.5 passes. Do you mean something like slot 1, stick A then Stick B, then slot 3, A then B?

    Naive question. How is the correct voltage determined? I'm not overclocking or doing anything else to soup up performance. But, its been running fine for a year.
  9. Check the memory voltage on Newegg and put it in the bios.
    I am not getting the right part on Newegg.com.
    It may be the cause of your BSOD.
    Rerun memtest86+ with the correct voltage.
  10. Is that Twin2X4096-6400C5?
    Is this the correct model?

    http://www.newegg.com/Product/Product.aspx?Item=N82E16820145184

    The voltage for this is 1.8v. You don't need to make any changes.

    Yes this is the correct one. I think I read it as a CS and its really C5 but I will check the voltage. This is on my home machine, I'm at work now so it will be later this evening. I'm also going out of town on Thursday for several days, so it may take a while if I don't find the problem by Wednesday.
    Thanks for the help.

  12. Okay, I've done some testing.
    Memory stick A was tested in slot 1 for ~3.5 hours, 0 errors reported, 662%
    Memory stick B was tested in slot 1 for ~9 hours, 0 errors, 2220%, but then it blue screened
    Memory stick A is now in slot 3 for 5 hours, 0 errors, 1243%
    I'll swap in stick B shortly

    Is this enough to tell us anything? Is stick B suspect?
  13. Try running the computer with only stick A.
    See if there are any more problems.
  14. remove the most recent hardware ( the printer )
    remove the most recent comp drivers (the printer)
    remove the most recently installed software (most recently installed game, software, driver so on)
    set the pc to advanced system setting > system > starup and recover > settings > no kernal dump

    all this should be done in safe mode

    i hope this helps

    ps why do you think its ram bsod will shut you down as is anyway .....

    Hi again, I've been away for a few days.

    When I returned the computer was still running, hadn't rebooted like it does when there's been a bsod. I put both sticks back in and also ran registry mechanic, which found some errors. Has been running for a couple of days now without crashing, thats something of a record recently. I'm just going to watch it and see if it misbehaves again, but so far looks good.

    It was suggested on this forum that it was probably a ram issue. At this point I'm just going to watch and see what it does. If I have more problems I'll follow your suggestions, but tell me what happens if "no kernel dump" is selected?
