Building my first system. All went well, until I began to update drivers. I get random crashes, resulting in BSOD's with ndis.sys and DRIVER_IRQL_NOT_LESS_OR_EQUAL. These crashes seem to occur with the beginning drivers from windows 7, or from most updated ones. I have re-installed windows 7 several times.
I have ran memtestx86 for 6 six hours with no errors, so I think the RAM is ok.
I would greatly appreciate any advice.
Thanks in advance,
My system specs are:
Corsair 750W PSU
M4A79XTD EVO mobo (0704 BIOS)
X4 955BE AMD CPU (C3)
4 GIG 1333 DDR3 RAM GSkill
EVGA GTX 260
Windows 7 64bit OS
I really appreciate the response. Unfortunately, as I am running the 195.62 NVidia driver, this does not appear to be the problem. I see these random BSOD with either the default driver that Win 7 installs, or with the most recent Nvidia drivers.
As near as I can tell, my drivers for ethernet (Realtek) are current.
Before I attempted to confirm that RAM settings are stock (not sure how to do this, yet), I got a response from ASUS. They politely suggesting I remove the CMOS battery to get back to default conditions. Did this, same BSOD after a reboot or two. Then they suggested I breadboard this system - also done. (Sigh....all my work on cable management!) After rebooting a few times, same BSOD. Their next suggestion was to re-install OS. So, as I start that, I get this BSOD error on the intial boot with WIN 7 in the Odrive which should bring me to the boot menu. Instead, I get:
Your RAM will have a sticker on the side with the rated speed, timings, and voltage. You should start by manually setting all those values in the BIOS. This is a pretty common error when the RAM isn't getting enough voltage. Memtest86+ is great for finding faulty RAM, but not great at detecting incorrect settings. I would bet that the RAM isn't faulty, your motherboard probably just isn't giving it enough voltage under "Auto" settings.
Hmmm....when I load up one stick of RAM...call it stick A...I got the BSOD mentioned above. When I load up stick B, same RAM for the same 2 stick package, I get no errors at all...after 10 reboots, loading OS, drivers, etc.
The ram is 1.5V stock, which is pretty low (I think?). I do not understand the ASUS bios well enough yet to set the ram voltage...looks like I may have to do that in the OC section - even tho I have no intention yet of OCing.
And yet, I did run memtest86 v4.00 for 6+ hours on with both sticks in the machine...and got no errors at all.
So, somewhat confused, but proceeding carefully on the assumption of one bad stick of ram.
