Blue Screen while using JTAG

[Altera_Forum]

Hi all, 

I am new here and need a help.   I am working with Altera JTAG device on windows XP using NIOS IDE. Sometimes all works fine but in many cases when i trying to enter debug mode i getting a blue screen :( with an error of: "IRQ_LESS_OR_EQUAL".    Does someone familiar with a similar problem?  Can someone help please, once it was rare but now its happens a lot and wasting a lot of time.   Thanks :), Michael

I had this issue with my VGA. Same error. No cures :( Anyway, check if You're NOT plugged Your JTAG adapter to USB3 port. Sometimes USB3 doesn't work.

I hit get new data and then BSOD -> Page Fault. This only happens in SignalTap all others tools (and there are some memory intensive ones I use) run fine. Didn't get this in the past on older versions of Quartus on the same machine either.   I use Quartus 12.0 Build 178 05/31/2012.   I cannot reproduce the error, but it seems that the bigger the SignalTap is (use of internal memory, amount of data watched), the sooner the BSOD occurs. Sometimes I can debug for several iterations (compile, debug, correct, rinse&repeat), today the Tap BSODed me on the first read after starting my PC and Quartus.  Gotta ask my boss for an updated license I guess, hopefully the current build is more stable again.
