I've recently built a new PC. It boots fine runs fast but will randomly shut down like someone pulled the plug.. I've always related these kind of crashes to an overheating problem. Most of the time it runs for 1HR + before crashing and wont crash idle but when gaming, etc.
The PC:
ASUS P5N32-E SLI LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard
Intel Core 2 Duo E6600 Conroe 2.4GHz 4M shared L2 Cache LGA 775 Processor
ZALMAN CNPS 9700 NT 110mm 2 Ball Ultra Quiet CPU Cooler
Antec Performance One P180 Silver cold rolled steel ATX Mid Tower Computer Case
EVGA 320-P2-N811-AR GeForce 8800GTS 320MB 320-bit GDDR3 PCI Express x16 HDCP Video Card
CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory
HIPER HPU-4S730-MS ATX12V v2.2 730W Power Supply 100 - 240 V
All the above is new. I re-used my old Hitachi 80G SATA HD, DVD and CDR Roms.
What I've done:
I've used a few different programs to keep an eye on my temps (nVidia Monitor, RivaTuner and Speedfan. The CPU seems to idle around 32'C and the Vid Card around 60'C (after I turned the fan speed to 100%). Every time I crash I try to feel for hotspots but dont seem to find any so I dont thinks its a heat problem. My case runs 3 120mm fans (Top, Rear, and lower chamber) and the PSU has a front and rear fan.
I was running 4GB of the CORSAIR XMS2 and my BIOS found all 4GB but XP would ony show 3GB. I read some stuff on why that was (32bit OS) and even found a guy who was having the same problems as me and drop his comp to 3GB and it went away. Pull a stick out and ran 3GB, still shut down after an hr or so. Took out another and rag 2GB and still the same problem.
Pulled CPU fan off whipped thermal paste clean and applied Artic Silver and re-mounted the fan just to make sure the CPU was keeping cool.. I've never used a fan this size before so I didnt want that to be the problem.
And last I thought maybe a PSU issue. Rearranged some of the power, made sure everything was seeded tight and HD,DVD and CD had its own line with a fan on the CD, DVD and Floppy lines. Vid Card is using its own PCI-E power line. I used Speedfan to check the voltage but I have no experience with voltage, amperage, etc. Here is a quick view:
Vcore1: 1.25V
Vcore2: 3.20V
+3.3V: 0.00V
+5V: 4.95V
+12V: 12.03 - 12.10V
-12V: -16.97V
-5V: -8.78V
+5V: -4.87V
Vbat: 3.01V
Ran a stability test for 10 mins, 50 passes all completed. Ran idle all last night 11:45PM - 8:00 AM. Was going to run a Prime95 stress test but wanted to get the system stable first.
Please help.. PSU? MEM? Overheating?
