I purchased this computer 3/25/12 from Newegg (items that were purchased at separate times: case, internal fans, pci slot fan, fan controller). Mainly the issues I've been having revolve around system stability and random system crashing.
The problem was intermittent for such a long time (and I was in college) so I never bothered to get my system rock-solid stable. I've been able to get by for about 14 months without serious issues, but now the problem seems to have gotten worse. Initially my system would crash (as in the computer would restart itself and/or shut down) after 4-6 hours of gaming. I was playing a lot of Star Wars: The Old Republic at the time, if that matters. So I troubleshoot online (read: Googling), and my feedback is that it's most likely heat-related (In the reviews of my GPU people recommend having software-automated fan control for proper cooling). My GPU is rated at 100° C max on the NVIDIA site (http://www.geforce.com/hardware/desk...specifications), but it reaches upwards of about 80-85°C during heavy gaming. Now--my Lian Li case's airflow design is reversed from the traditional design (intake fan in the lower back, exhaust fan in the lower front) so the areas around my GPU tend to become a pocket for heat. Also the front of the case has very few vents for exhausting heat. So at this point I'm convinced that the random shut-downs must somehow be heat related. I did several things to correct this: Added the pci slot fan above the GPU, added another fan onto my CPU cooler, and cut a 120mm blowhole out of the front of the case. So for heat control I have four 120mm fans, the pci slot fans, and the fan controller. She's one windy beast with the fans fully cranked. Idle temperatures for my GPU are 35°C and for my CPU 38°. Peak stress-temperatures reach 75-80°C for my GPU and 50°C for my CPU. I had been really busy with school so for a time I didn't know if the problems disappeared. Fast forward a few months.
So I've owned the computer for about 18 months now, and it seems pretty clear that the problem is not heat related. Also, instead of random shutdowns or restarts nowadays, my system crashes and the screen goes black (but the computer stays powered-up). Sometimes, my GPU fan will kick into full throttle during these crashes. I have to hold the power button and hard reset. Unfortunately, the memory is not on my motherboard's qualified vendor list (Located here: http://www.asus.com/Motherboards/M4A...3/#support_QVL).
Also, my motherboard has been unwilling to boot lately with 16 GB of ram installed. I'm fairly certain I used to have 16GB installed, but took 1 stick out several months ago while troubleshooting and now I am running 12GB. At first I attributed this to the motherboard's stinginess (in this mobo's reviews on Newegg, people pointed out difficulties in running 16GB). But now, I think my DIMM slot number 2 is somehow broken. Currently DIMM slots 1,3, and 4 are filled. I have tried booting with just 1 stick of ram in DIMM 2, and with 2 sticks of ram in DIMM 2 and 4. I've also tried using MemOK to help detect boot settings unsuccessfully. I just can't seem to POST using DIMM slot 2 at all. Maybe that's obvious indication that my motherboard is failing and that it's likely having issues elsewhere. I don't know.
It seems like, at times, I can stress my computer without issue and without crashes, but at other times the system will crash not long after booting up a game or watching a movie on Netflix.
Troubleshooting that I've done:
--BIOS update (I already have the latest version)
--Followed the memory timings for black edition CPU using this sticky in the AMD BIOS settings forum (http://www.gskill.us/forum/showthread.php?t=7688). I've also tried the DDR3-1333 settings ("Fail-safe defaults") with the same issues.
--Swapped the 6-pin GPU power connector
--Run ChkDsk without problems
--Run Memtest on all 4 sticks of ram individually (in DIMM slot 1) without errors
--Run Memtest on 3 sticks together (inserted in DIMM slots 1,3,4) without errors
--Run Memtest on 2 sticks (inserted in DIMM slots 1,3) without errors
--Run Prime95 "Small FFTs" for 8 hours without crash
--Run Prime95 "Blend" for 12 hours without crash
--Run Furmark GPU Stress Test - fullscreen, 1920x1080 4x MSAA Burn-in test for 30 minutes without crash
Ways to force a crash:
--Run Prime95 "Large FFTs" for 6 hours until crash
--Playing any graphics-intensive game. Sometimes the system will crash in 20 minutes, other times in 2 hours under the same timings/voltages. Very random.
--Tried my on-board MemOK button to auto-detect fail-safe defaults (sets my memory timings as 11-11-11-28-2T). My system froze several times in BIOS, and also while loading Windows)
--Tried running Memtest with BIOS fail-safe defaults (everything is on auto--crashes very frequently without manually entering RAM timings)
I've attached photos of my BIOS to help guide the process of finding the correct timings (and sharing other BIOS settings just in case).
My computer is usually stable if I'm doing nothing but web browsing or word processing. But it has crashed several times while watching Netflix or while using Adobe Photoshop. Unfortunately I don't have a spare PSU, GPU, or other computer to swap components but am willing to RMA if possible. I'm also willing to buy new hardware if it means testing/fixing the problem.
Sorry for the long post. Very frustrating. Please let me know if you have any suggestions. Thank you for your time.
