IRQ problem?

[SpookyMark]

I am having a problem with my XP Pro, I keep on getting BSOD with this criteria "irql not less or equal" and I am wondering if having three components on the same IRQ could cause this, I have Sound Card, USB port & my Adaptec 2940U2W on the same IRQ.
Some people are telling me that the drivers for my ATI Radeon will do this error, but the strange part is the fact that i have had the same card on my other PC that does not have SCSI card in it & the problem is not happening there.

Any suggestions please

Thanx

well.. why dont you change the IRQ's that your cards are on, so that there are no conflicts?

worth a shot at least.

first off, have a read of this FAQ!
most likely due to a driver problem.
this is what you'll get from the KB!

"irql not less or equal" is indicative of an unstable system. If your system is overclocked, back it off a bit. You may also want to check your RAM.

The RAM I have is TekRAM 384MB three seperate 128MB sticks sitting on a ASUS CUSL2 motherboard.
Additional spects:
PIII 800 EA
ATI AIW Radeon 32MB DDR
WD 40GB HD 7200RPM
Adaptec SCSI 2940U2W
Plextor UltraWide 32X
Phillips 4X4X32 CDRom IDE
SCSI Zip Drive (kind of old)
DECAVIEW 17" G387 Monitor
Netgear NIC
Creative LIVE SoundCard Value

Unstable. RAM problem. Generally, unless your RAM is Crucial or Mushkin or very high quality RAM, the ASUS CUSL2 will not run all 3 DIMMs at 133MHz.

Even then, the board is running out of spec as the i815E chipset is designed to operate with only 2 double sided DIMMs at 133MHz. Having all 3 DIMMs is supposed to only operate at 100MHz. ASUS managed to get around the limitation, but as I said, you need high quality RAM and it is hit-and-miss.

Go into the BIOS and set SDRAM Data Driving Mode to Strong. That usually helps to run all 3 DIMM slots at 133MHz stably. You may also consider increasing the IO Voltage by setting the jumper on the motherboard.

IO Voltage is nominally 3.3 volts; ASUS factory default the VIO to 3.45 volts. You can increase it to a maximum of 3.56 volts (this board only has 3 settings). Anything up to 3.7 volts is safe, so there is no need to worry about frying anything.

Andy,
Thank you for the suggestio, it makes sense, I have another PC with a CUSL2 motherboard, PIII 800 EA, 256MB (2 sticks), ASUS V7700 GeForce2 Deluxe card, IBM 30GB 7200RPM Hard Drive, IntelNic, ASUS CDRom 50X
This one is not giving my any trouble,
At first I thought it had to do with the Video Card so I swapped them around, I have moved my ATI to the 2nd PC & GeForce to the first one & I still had the same problem with system rebooting itself, then I put the cards back & tried the standart Microsoft drivers to see if maybe there was a conflict or a problem with the drivers. That was not it, at that point I was a little stumped. That is when I posted the question here.

So now i will try what you are suggesting, but what if I was to get some other memory (2X 256MB) do you think that would help too?
