Random blue screens

By Carlito

  1. Hello all.

    I have the following pc specs and would like to know if there is a possible solution to my problem:
    System Manufacturer:ECS
    BIOS: Default System BIOS
    DirectX Version:10
    Operating System:64Bit Vista Ultimate
    Motherboard:Elitegroup P4M900T-M2 Supports DDR2 667 up to 4GB
    Power Supply Unit:450Watt
    Hard Drive:Seagate 160GB SATA
    RAM:2046MB (2x1GB DDR2 667)
    Graphics Card:Zotac NVidia GeForce 8600GT; 512MB dedicated video RAM(total approximate memory:1264MB); Pci Express; DAC type: Intergrated RAM DAC(not that I know what DAC type is)
    Sound:On board
    Display: Dell 21.1" wide LCD

    The problem that I have is the fact that I get random blue screens. The stop messages are listed below. This happens very often and I even tried formatting and while I'm in the process of installing Windows then I get a blue screen with either one of these messages. There is no particular order in which it happens so I cannot predict when it happens and therefore can't do troubleshooting or process of elimination on my own. Even installing XP makes no difference. I've tried removing the graphics card completely and uninstalling all the software and drivers for the card and running from onboard VGA as I initially thought that this could be a problem relating to the graphics and as I've said, process of elimination does not work/help. Some one on the forum suggested to some one else with a similar problem to simply change the fast boot setting (in CMOS/BIOS setup) to normal boot and this also doesn't help. I've done memory diagnostics test and even then do I get a blue screen. I have, however, managed to complete the memory test with 3 passes and this says that there are no problems. I assume that the problem is then therefore not a sustainig or constant one for the tests to detect it but rather one that just happens at a certain point/time. A friend told me that I might need a higher powered power supply, but for crying out loud, I have a 450W unit which should suffice and it came with the system. I also checked that all my fans (CPU, PSU, and Graphics Card fans) are working properly and they are. At least they seem to be. So that should rule out overheating. What to do, what to do. These blue screens seem really dangerous and I am a little concerned that if I continue to use my machine then it will break for good. Is this the case?

    Another question that I have is do you think my motherboard can support DDR2 800 RAM and could it be that I need this particular RAM? Although I, myself, doubt this.

    PAGE_FAULT_IN_NONPAGED_AREA
    STOP:0X00000050(0XFFFFF6800685FA58,0X0000000000000000,0XFFFFF8000988A317,0X0000000000000002)

    I really do appreciate all the help and thanks alot.

    When you say memory test were you using Memtest? The reason I ask is because Memtest needs to have run for a minimum of 7 Passes. That error list you gave is a strong indication of bad memory.

    Also, just because a power supply says it puts out 450 watts doesn't mean it does so. Many people here build systems and very few would trust a power supply that comes with a case. Since it is a Dell maybe it is fine.

    Your one 0x50 error listed ntfs.sys. Try this:

    1. Run ChkDsk

    2. Run a full harddrive diagnostics.

    I've tried MemTest and the blue screen just won't allow it to go even beyond 100%. What I have,however, done was to remove one of my ram cards to determine if the test will run better with only one. I've done the memtest to check both ram cards and all seems fine. It runs up to over 600% on both cards installed individually/seperately. What I can now deduce from this is that I need a better powered power supply, because there is (possibly) not enough power being sent for the ram to work together and that's Possibly why I can run better with only one installed(1024mb ddr2 667mhz). I've also used Seatools to determine if my hdd(Seagate 160gb) could posibly be faulty and this is not the case. I've run chkdsk also with no errors. No viruses either. It seems to all point to power issues. I've been running for 3 days now with one ram card and no errors, although some games and programs run slower(obviously). So until I can buy a new power supply I'll just use 1024 ram.

    Thanks for now and I appreciate the help.
