System specs:
Motherboard: Foxconn C51XEM2AA-8EKRS2H
CPU: AMD Athlon 64 X2 5400+ Windsor
Memory: CORSAIR XMS2 2GB (2 x 1GB) (PC2 6400)
PSU: Antec Neo HE 500W (12v rated at 17A)
GPU: eVGA e-GeForce 8800 GT Superclocked
Sound: Realtek ALC882D
2 HDDs
1 Optical drive
2 USB peripherals (mouse and keyboard)
4 case fans (80mm)
My system locks up in 3D games, usually when GPU temperature is high (68-71C).
Graphics get corrupted, sound stutters, system becomes unresponsive and has to be reset.
No events in windows event manager.
System status:
-Hard drives are defragmented often
-CPU, GPU, and Southbridge heatsinks have had fresh thermal paste applied recently (IC Diamond paste. Fujipoly pads for GPU VRAM). Problem occured before these changes, still occurs.
-System is de-dusted often
-2 fans in back, pushing out, 2 fans in front, pulling in
-All component/chipset drivers/BIOS are up to date
-Driver Sweeper used to clean out old drivers when updating (multiple safe mode reboots, etc.)
-DirectX is up to date
-Soundcard acceleration set to Standard (notch below Full)
-GPU set to standard clock speeds (superclocking removed)
-CPU is at standard clock speeds
-Memory is at standard speeds
-Memory has been reseated several times
-GPU 6-pin power cable is on seperate rail from other devices
-All cables are well-connected
-No hardware conflicts in device manager
Stress tests:
-Furmark and eVGA OC Scanner did not cause a lockup, and were stable despite much higher temps (85C)
-Memtest86 found no memory errors
-Prime95 had no problems and CPU was stable
-System was stable even if Furmark, OC Scanner, and Prime 95 were all running at the same time (simulating max load).
Possible culprits:
-Power supply is 500W and 6+ years old now. Maybe not powerful enough to handle everything/Failing?
-PCIe slot is fidgety. Switching graphics cards sometimes causes system to not POST correctly. LED error codes, some related to memory, but as said, memtest finds no errors, and memory has been properly seated/reseated many times. Jiggling/reseating Memory eventually allows system to POST and boot up correctly, though it will say previous BIOS settings were not stable and prompt for BIOS entry or to continue.
-Southbridge heatsink fan is right underneath GPU card, may be getting too hot. 40mm fan.
-Northbridge has passive heatsink, gets too warm to touch (1-2 secs = ouch). Maybe too hot?
Speedfan readouts below:
Min. Max. Avg.
GPU: 48.0 68.0 49.0 (idle)
System: 50.0 54.0 51.1
CPU: 50.5 54.0 51.1
Aux: 50.5 56.0 51.3
Local Temp: 35.0 41.0 35.3
Remote Temp: 33.0 52.0 33.5
CPU: 40.0 60.5 41.0
Local: 38.3 52.0 39.2
Remote 2: 39.8 60.3 40.8
Speed02: Setting to anything but 100% causes CPU0 Fan to go to 0 RPMs
Speed05: GPU fan
Altering other Speed0X settings causes no change in fan readouts.
+12v fluctuates between 8.45 and 8.70 (doubt these readings are accurate, or my system wouldn't even be able to boot, eh?)
No hardware program I've tried gives the same +12v reading (some are extremely high, some extremely low), and BIOS has no +12v info in it.
Other voltages have negligible variances.
Any ideas would be highly appreciated, and sorry for the wall of text.
