Before I start, let me say that all you at Bleepingcomputer.com have been incredibly helpful to me in the past, in resolving virus/malware/spyware stuff, and for fixing another game problem. However, now we come to another hurdle to leap over, as is the norm with computers.
So I got a new computer about 2 1/2 months ago, and I must say it is a pretty nice rig compared to my old one. Here are the specs (for referencing any known problems with these devices, and, well, to brag):
CPU: AMD Phenom 9600 Black Edition (The one with the unlocked multipliers, however NOT OVERCLOCKED until I can fix this problem)
Gfx: ATI Radeon HD 3870 512MB GDDR4 (Powercolor, PCS version)
Memory: 4GB Mushkin 800Mhz DDR2 (Running in Ganged mode)
Mobo: Gigabyte GA-MA790FX-DS5
HDD: 500GB WD Caviar (SATA)
OS: I run XP SP2, because Vista is an angry vampire
Here is the problem:
1.) Started playing Bioshock, glorying in my new gfx, having a boatload of fun at 1680x1050 on all maxed out settings, still getting like 90 FPS or some such.
2.) After a while of playing, my video locked up. The cursor was still free for a little while, and the audio kept playing as normal, but then the screen flashed static for an instant, and went to black, meanwhile the audio started looping. Eventually the monitor completely shut down, but the CPU and HDD were still working, not like something that would happen in a CPU overheat or a surge.
Here's what I did to try to fix it:
I immediately tried to play another game to see if the problem was only Bioshock-related. I tried playing Supreme Commander, Company of Heroes, and the emulated version of Halo 2. Same thing happened. After this, my thoughts immediately turned to an overheat. I checked the temperature sensors using AMD Overdrive up until a few seconds before the crash, my CPU temp remained well below my margin of 80C that I set for the warning alarm, my two motherboard sensors (one at the North Bridge, the other at the South) were fine. I checked the GPU sensor, it read a very stable 41C. My next thought was that the sensors might be faulty, so I ran the game up until the crash while having a friend point an infrared thermometer into the GPU of the vcard, to the side of the CPU (under the heatsink), and on the memory as well as the N & S Bridges; the temps were completely stable.
Next I thought it might be a driver problem. I installed newer display drivers, new chipset drivers, new CPU drivers, updated Windows fully, then went to BIOS and set everything to Fail-safe (but kept the temperature settings the same) The problem still happened.
Then I thought it might be the TLB database erratum thing that the 1st and 2nd stepping AMD CPUs were supposed to have. I enabled the BIOS option to fix it, and also disabled the Auto-Express stuff for the GPU and CPU. Still had the problem.
Then I ran an Adaware, Panda, AVG, and a Panda Online scan, and they turned up with nothing whatsoever.
THEN I reseated all the hardware, including the CPU, vcard, RAM, and turned all the fan settings up to high, nothing helped.
Now I need help, PLEASE come through for me, Bleepingcomputer.com
