Hi,
I built my PC around six months ago and frequently have problems when running games. It blue screens with the error message 'DRIVER_IRQL_NOT_LESS_OR_EQUAL'. I've got an MSI KT4 Ultra M/B with PC3200 RAM (512Mb), an XP2400+, GeForce4 MX440 (AGP 8x). Windows 2k SP3, Direct X 9.0a. I was told that it was linked to my video card drivers, so have tried the latest drivers as well as older versions. I have also been told it is a problem with McAfee VirusScan 7.0, but disabling this does not help either. Anybody got any ideas?

This error is almost definately referring to your gfx card. Make sure all the settings in your BIOS for your AGP bus are set right. Also check your memory timings - it might be these too. Make sure your PnP configuration is set to automatic - if it's been left on manual the system may be having trouble allocating IRQ's.

Hope this helps.

Cheers, I think this may have helped.

As far as I can tell the timings for my Samsung memory are:

CL 3
tRCD 3
tRP 3

I'm not sure, but have taken CL to be CAS Latency, tRCD to be RAS to CAS Delay and tRP to be Row Precharge. Is this correct?

Samsung also say that this memory should run at a bus frequency of 200MHz. With my processor (2400+) the bus rate is 133MHz(266MHz), could this be a problem?

Thanks again for your help.

If your RAM is only supposed to run at 100/200Mhz, then running it at 133/266 could pose a problem, yes. With an AthlonXP 2400+ though, you should really be running 133/266. Try and get hold of some different RAM which is definately 133/266 and try it in your PC, see if the problems disappear.

I shouldn't have drank so much last night, it took me 15 mins to write that paragraph.
