Built a completely new system from scratch, and everything seemed fine under the normal Vista environment.
Sadly, once I loaded up Crysis things went awry.
I'm now getting IRQL_NOT_LESS_THAN_OR_EQUAL BSODs after seemingly random periods of time under heavy graphics demands. Can happen within half an hour, sometimes goes hours without a hitch. More often than not it cans out on trying to load a new level.
Anyway, here's the system specs...
Windows Vista Home Premium 64 bit
Q6600 Core 2 @2.4GHz
2 GB OZ 1033 MHz DDR2
BFG Nvidia 8800GT
Arctic 700W power supply
Samsung 500Gb SATA drive
Ideazon Z-Board USB keyboard
The IRQL BSOD is really unhelpfull as it could be lots of different things causing it.
Memory checks out fine on a memtest.
Vista fully up to date and hotfixed with the 940105 GeForce hotix.
Currently running 169.25 forceware drivers.
My current thoughts lean towards something being amiss with the graphics card/driver setup but I'm not skilled enough to go any further to proving it.
I certainly can't tell if it's a hardware issue and the factory overclocked card is physically damaged or whether it's a simple case of drivers not yet catching up with the OS. I'd rather not send a perfectly fine card back and be without a rig if I don't have to.
Anyway, any hints on where to go from here to nail down/fix my issues would be appreciated!
Have you configured your RAM in BIOS? Increase the memory voltage first of all. Set the timings manually to Mfg. specs. If BSOD continues to occur, try increasing the NB voltsg. If problems still persist try some other RAM.
