Help Please

Very good, Joker. Please post back and let us know how your system is doing one way or another. If you don't get another BSOD in a couple of days, let us know and we will mark this thread as solved. If you get another BSOD, post back ASAP.

Fingers crossed!

Thought it was too good to be true! Back to The freezing screens with horizontal lines which don't create mini dumps or if Im lucky a BSOD. I'll attach the latest mini dump if you guys would be kind enough to have a look at. I never had all these problems when using my nvidia gpu. Only started happening since HD 5850. I'm tempted to RMA but the card is superb in 3d and you don't see the reference design cards about anymore!

Again caused by memory corruption, with bugcheck 3b. This is likely to be your video card drivers, which sounds right on the mark with what you were saying.

You might try removing and reinstalling your video drivers, as admin.

I will try a reinstall of the drivers yet again. I have been using driver sweeper to clear out all traces of the old drivers. This seems to work for a bit then its back to the crashing again. If its a no go again then its RMA time which is a shame. I think if I disabled powerplay things would be fine but I don't want to be running 3d speeds constantly. Just out of interest, after the last crash I had problems even booting into safe mode. After a mobo battery change finally got it to boot and had another mini dump. Is this still pointing to faulty video card? If so would It mean that AVG wasn't the culprit earlier in the thread? Thanks again guys.

PC has been stable since the last install of 10.6 drivers but it did this last time and then started crashing again so not too hopeful. I have contacted MSI and given them all the details and will see what they say. Will probably involve flashing the gpu bios. Would love that to work as really love this card in 3d just not 2D. I have attached a pic of the screen when PC would lock-up and require a reboot. It would do this if I didn't get to the BSOD. Not the best of pics but shows the screen corruption.

That is definitely some screen corruption! Let us know what MSI has to say. I agree with Jonathan, I think it is time for a new card.

Hi guys. All seemed to be going very well until now. Just checked on PC and it had restarted and was left with the message;

File:\Boot\BCD
status: 0x000000f
Info: An error occurred while attempting to read the boot configuration data.

Befor I RMA the card was just wondering if it could be my motherboard or hard drive at fault and its just a coincidence things started to go wrong when I swapped GPU? I have run dskchk and everything was fine. I have also had a look at mobo and things look fine. No swollen or leaking caps. I'm gonna see if I can get hold of an nvidia card to see if things improve before I RMA ATI card. What do you guys think? Would it be worth formatting again? Tried this before and it was fine for a couple of days before it started playing up. Can you recommend some decent software to test hard drives? I have attached latest mini dump file to see if points to anything. Thanks again.

REFERENCE_BY_POINTER (18)
Arguments:
Arg1: 0000000000000000, Object type of the object whose reference count is being lowered
Arg2: fffffa8005f52900, Object whose reference count is being lowered
Arg3: 0000000000000002, Reserved
Arg4: ffffffffffffffff, Reserved
    The reference count of an object is illegal for the current state of the object.
    Each time a driver uses a pointer to an object the driver calls a kernel routine
    to increment the reference count of the object. When the driver is done with the
    pointer the driver calls another kernel routine to decrement the reference count.
    Drivers must match calls to the increment and decrement routines. This bugcheck
    can occur because an object's reference count goes to zero while there are still
    open handles to the object, in which case the fourth parameter indicates the number
    of opened handles. It may also occur when the object’s reference count drops below zero
    whether or not there are open handles to the object, and in that case the fourth parameter
    contains the actual value of the pointer references count.

This dump doesn't tell us much except that it points to hardware or drivers.

To answer your question, yes, it could be the motherboard; but I would have expected some different error codes if it were the motherboard. I am still leaning toward the video card based on what I have seen.

Thanks Carl. I think I'll see if I can swap graphics cards with a mate and see what happens. PC does seem to be much more stable with catalyst 10.6s' but i want it 100% stable. MSI have asked me to try another card before they send me a new bios. I will let you know what happens.

I've put in an old 1900xt for the time being so will see how that goes. Could the sort of artifacting I've been getting be caused by a faulty power supply? Just want to rule everything else out before I go down the RMA route. I bought the PSU at the same time as the card. It's an Antec Truepower New 650 watt. Would be strange as the PC runs 3d perfectly fine though.

Antec is a reputable brand, but every product has a certain risk of failure.

If the PSU is faulty, it can result in random errors difficult to diagnose. BSODs are a possibility.

If you have another PSU to test, for it.

Well it doesn't look like its the graphics card. I haven't had the artifacts again but computer has been locking up in windows and even in bios. I won't be able to test power supply until I bring my volt meter back from work Tuesday. Is there any software which can monitor voltages accurately? The CPU is fairly new so I don't think it could be that. I have run memtest overnight and it found no problems but I am running with just one stick of RAM to see what happens. which component do you think is the chief suspect?

Do you have any new dmp files? I have to suspect hardware since you are having problems in BIOS.

Hi Carl. Unfortunately the crash didn't create a dmp file. Since I have only been running with one stick of RAM so far the system has been stable. I ran memtest overnight and no errors were found. I will run it with the other stick tonight. Could the system be struggling to run 800mhz dual channel mode with ATI cards? If so could it cause crashes like I have been experiencing? It ran 800mhz fine with nvidia. Would it be worth running 667mhz and see if its stable? I noticed in BIOS that my motherboard won't allow me to enter the correct timings either. My memory is CM2X2048-6400C5DHX which should run at 5-5-5-18. I can only set 5-5-5-15. Was never a problem previously but I am wondering whether The ATI cards are fussier. I can rule out the power supply tomorrow when I can pick my volt meter up. Could intel speedstep cause issues like this? Sort of plucking at straws now!

I would say that since you are stable with one stick, the indication is definitely a RAM problem. We will know more when you test the other stick.

When you start asking about the capabilities of your board and its effect, you are out of my area of limited expertise. I am not a hardware guy. If your system is struggling to run your RAM, yes it can definitely trigger crashes. I have never delved into RAM voltages, overclocking, under clock, etc. But there are some good hardware folks here. I will post a call for help with your questions. Stay tuned.
