thanks guys
i used AsusProbe and MBM and logged everything possible - voltages, temperatures, fan rpms. In fact I sat staring at the screen most of the time trying to spot inconsistent patterns. The system ran fine for 2 1/2 hours, and there seemed nothing wrong with the data (cpu at a constant 50 deg and MB at 40 deg)and then AsusProbe says ..error accessing some memory location (in hex) and before i could note the message down, I get this BSOD "IRQL_NOT_LESS_OR EQUAL". The system reboot after doing a mem dump and just as the desktop comes up I get another BSOD "PAGE_FAULT_IN_NONPAGED_AREA" and the system refuses to boot again with the beeping . This last error makes me feel it's got something to do with RAM.
OR can it still be the CPU/cooler? It's always run at 50 deg.
I'm going to do 2 things, get the sytsem fully cleaned up (there's not much dust really)and get a volcano 7 or anything u advice... I've a volcano 3 at the moment.

If the CPU is running at 50 degree then i think it is find, must be something to do with the RAM. buying the Volcano 7++ will not help cause the processor is running at ideal tempreture. Why don't you try to borrow RAM from your friend or whatever and use it, see if this fix.

Best of luck.............!

case closed!
yes, it was RAM indeed! thanks a lot guys. I just replaced the stick with another (Micron) and the comp has been up for like a dozen hours now :wink:

now plz don't go ebay and write:

I sell xxx MBs of RAM which is not tested ....
no gaantie at all ..... I really hate that .... some days ago I have seen somebody who really has to be send into jail .....

his article:
GeForceFX 5900 with MB ? dunno (could not really translate it from german since there is no word for "dingsbums")
sell a GeForce FX don't know what card it is .. (and some other BS ...)


hmmm OK ... but 150€ ? .. so I looked up his ID card ....
This ****ing guy is buying a GF FX5200 for around 60€ then putting the carton into an auction which looks like you buy card ... and next to it the above text just for the card ....
