Could my memory be bad?


Recommended Posts

Hey all, I have a few questions for you. I apologize in advance for this being so long but I am trying to fit 6 months of info in here. I have been having major problems over the past 6 months or so, I get a lot of blue screens and other errors. It used to only happen when playing a game, then it started happening at random. Sometimes when I would open a program, sometimes while going to a website, and sometimes when it was just sitting there. I have not much time to do anything about it but it is happening more and more frequently, and I am starting to lose some data because of it.


This is what I have:


AMD 3000+ Barton 400FSB

ASUS AN78X-E Deluxe

1GB kit CMX512-3200XLPRO

Thermaltake Polo12 410W PSU - I bought an Ultra X-Connect 500W 2 days ago to try a new PSU

ATI Radeon 9700 Pro - I swapped in an old Geforce 2 just to see if that was the problem.

2 160GB Western Digital SATA drives - Were in RAID 0 before, now no RAID

Windows XP Home


The stop errors seem to be random, I get many different ones and they don't seem to point to the same place. They mainly consist of









Sometimes I get a driver listed as the cause, sometimes I don't.









I have gotten others but those are the most frequent.


Several times I would get a blue screen, and upon reboot my registry would be corrupted. I had to replace all of the registry hives to get my computer running. I had to do that 3 times.


I have been through countless forums, I have found posts with 1 or 2 of the problems but not all, and most of those pointed to McAfee and Roxio or software like that, I have none of the software mentioned installed. Several mentioned a Windows hotfix for something similar, so I called Microsoft to see if this would apply or if they could help me out. After a few calls and emails I was told to reformat, big help. I was trying to avoid that at the time because I had almost 200GB on my drives and did not have time to go through the back up process, but I was out of options. I reformatted my drives and did a clean install. That didn't help so it must be a hardware issue. I started with calling ASUS and talking to them. They had me RMA my motherboard, same problem. I called Western Digital and they had me RMA my drives, same problem. I had run memtest before all of this and there were no errors. I decided to run it again, I ran it with both in there and each one individually. All of them ran for 5 passes and there were no errors. So, I switched power supplies and video cards, and I'm still having the same problem. The only pieces of hardware that are still in and have not been changed is my memory and my CPU. If it is not one of them then I have no clue, unless it is a cable or something like that.


Since all this things have gotten worse and more frequent. Since the reformat I have had to replace the registry haves 4 more times. CHKDSK has run 3 or 4 times when booting up. 2 or 3 times when it reboots I get a pop up that says tells me my system needs to shut down. I don't have exactly what it says but it states that win/sys32/lsass.exe is corrupt or something like that. Almost every time I get a blue screen, upon reboot it says the system has recovered from a serious error. I keep getting errors that something has to close. If I am using Firefox, IE, Outlook it tells me it has encountered an error and needs to close. This also happens to some other things like Dr Watson's Post Mortem Debugger and a few other background programs. None of the issues except for the registry haive replacement happened before reformatting or the new harware. It also used to happen 2-3 times a day, now it happens as much as 20-30.


So my questions are:


1. Is memtest foolproof? Is it possible that my memory could be bad even though it showed no errors?


2. Could it be something between my memory and mobo? I had to adjust the timings to 7, 3, 3, 2.5 to get it to even boot, could this be something further with the incompatibility?


3. If I try new memory, I will probably just go buy new memory and if that ends up being the problem I will RMA the old memory so I can get it sooner. Which of the following would be best for my system? Preferably one that is actually compatible, not where I have to slow the memory timings and end up paying a lot for memory half as fast as it shoudl be. This is what they have.







4. If it is not my memory, does anyone have any other suggestions. Would it definitely be my processor? Could it be anything else?


I've included everything I could think of, but if anyone needs any other info please let me know. Obviously I would be grateful for any help you may have, but it is getting to the point where I need to fix this immediately so the sooner the better. And don't bother telling me throw my computer off the roof, I have thought of it many times.

you must mean the A7N8X-E?

You need to switch out the memory for a known working one!

Also go into your bois and set it to default settings. You could also try another os like xp Pro. Also if your cd drive is going bad it will corrupt data when its transfering; I know from personal experience.


When you troubleshoot:

1. start with the simple things

2. have everything set to default

3. install only what is needed to boot up your system. nic,sound card,raid,extra hd are not needed

Yep, A7N8X-E Deluxe, sorry about that.


This is known working memory, just unfortunately not at stock speeds. There were many posts about this combo when I first got it about it not working with the stock timings. This computer was also running for 3 months or so with the same hardware before any of these problems started. Everyone had trouble with it but with the relaxed timings it worked. It is listed on the Corsair site as compatible as well.


It won't run with default settings. When I first built this it booted up, locked up, and then on reboot I had no video. I cleared the CMOS and it kept happening until I changed the timings which fixed it right away. The only other setting that has been changed is bumping the memory voltage up to 2.8.


There have been different drives in here and the same problem keeps happening. When it started I had a CD drive and a CD-R drive. I bought a DVD-R drive and that was the only drive in when I reformatted. Different drives, same problem.


I'm not sure if this will help at all but when I said I was losing data, this is what I meant. I run a business so I answer a lot of emails. I will be answering emails and when I am done I move them to a different folder. If my comp shuts off and I reboot, sometimes those emails will be gone. They won't be anywhere on my system and do not show in the sent folder. Sometimes it goes back 10-20 minutes, so if my computer reboots at say 4:00, the emails I answered and moved from 3:45 to 4:00 are completely gone.


I have been through all of the simple things I can think of. I have called Microsoft, ASUS, and Western Digital support with none of them having a clue. As far as booting with only what is needed, I have. The NIC and sound card are both onboard, I am not using RAID now, and I have tried using each of the drives individually and have also tried an IDE drive.


Thank you for the reply, I appreciate any help I can get with this. Unfortunately I have been through pretty much everything you mentioned with no luck.


If anyone knows for sure which of the memory I listed works with this board at stock speeds, please let me know. I may just get knew memory anyway even if it is not the cause of my problems. I mean, I did spend $330 on memory that Corsair says is compatible and it is running at speeds that should not cost $330. So even if you don't know what the problem could be, if you have this board and have used any of the memory I have listed with no problems, please let me know. Even if it is not the cause, I have still felt a little ripped off on this.

:eek: It would be cheaper to buy a new motherboard!!

Right, but that is my point. The 3200XLPRO is listed as compatible with the A7N8X-E Deluxe, but it isn't. Sure, it will work, but why would someone spend that kind of money for memory with such a low latency and then have to relax the timings so much. Maybe ripped off was a bit strong of a statement but it is without a doubt misleading to say the least. My question was, which memory will run in this board with it's advertised timings. If it says 2-2-2-5 on the packaging, that is what I am paying for and that is what I would like to use it at.


This post may have been pointless though, ended up buying a new CPU and 3 hours in, so far so good(fingers crossed). Kind of sucks though, no place carries the XPs anymore unless I wanted to order it but I didn't have time for that. Had to go from a 3000+ XP to a 2800+ Sempron, but it will do for now and if it fixes this BS I can't complain.
