At first it was "merely" tonelock; a problem which a few thousand users of Creative's Audigy 2 ZS seem to be experiencing. Guess what sound card I have? So I removed the sound card, did a cleansweep of all the Creative clutter on my system and rebooted. It ran like a dream for a few hours with onboard sound. And then... It crashed in the same fashion, just without the "squeal of death". And then... The BSOD's started. I've gotten numerous error codes with them: 000000c2, 1000008e, and most recently, 0x000000A "IRQL_not_less_than_or_equal". I've tried every suggestion given to me, at least once. Running memtest86+ for 24 hours, swapping out ram, swapping out CPUs, swapping out power supplies, installing new fans and heatsinks. I've done so much swapping, almost all the parts in my system are NEW. Originally, the problem(s?) would only crop up when I was running a high-end game like Doom 3 (Oddly, Half-Life 2 never had any problems...), Quake 4, etc. Now it seems everytime I look at the system sideways, it crashes. Even if it means a format and reinstall, or RMA-ing a certain part or parts, I just want my system to WORK. And please let me know if I'm not being very clear on things... Thanks.
