So, what do you do when you start to experience a series of random reboots, some with no 'Blue Screen' in BOTH windows and Ubuntu?
Start to pull your hair out I'll bet!
There is no easy way to diagnose this, but I'll keep you informed as I try to fix it, with your help guys and girls.
Firstly the system:
Gigabyte EX58-UD3R V1.6 BIOS: FB
Core i7 920 @ stock, HT and Turbo both on. Vtt 1.235, others: Auto. Vtt raised to keep nice 'space' from VDIMM
Zalman CNPS 10X Extreme
6GB Crucial Ballistix [3*2] 1333 7/7/7-24 Turnaround:2 VDIMM 1.66 [Sticks say 1.65, but I can only choose 1.64 or 1.66. Crucial support say 1.66 is fine]
700W Cooler Master Silent Pro
Zotac Geforce 470 @ stock BIOS V70.00.1A.00.03
WD 1002 FAEX
Sony DVD R/RW Drive
D-Link DWL G-520 WiFi
CoolerMaster Scout Storm.
Windows 7 64Bit Pro
Symptoms are: At some, seemingly random point the system will either BSOD or just straight reset. Sometimes an application will freeze first, sometimes not. This can happen in ANY application, and does not seem to be just because of load. Once it did it as soon as I ran Prime95, once when I was doing next to nothing. Has happened a few times in Assassin's Creed, but not always.
Once even happened after I had been stressing the system with Prime95 AND Assassin's creed and a 4GB 64bit Photshop pounding and streaming a video. Seeing as it took this for half an hour I had closed them all and given up to just browse the web!
So far:
Removed the reset switch.
Checked and reseated all connections, cards and thermal paste etc.
Checked all temps and cleaned heatsinks [all temps are less than 60c, bar grfx which hits 90 under full load]
Gently shock tested the motherboard, RAM and video card [tapped them gently while running looking for a poor connection causing a reboot]
I have updated my BIOS to FI [from FB] which is 9 months and 6 versions newer, and gone through the BIOS options with a fine tooth comb.
The PSU's Rails all look OK [loaded and unloaded], bar the -12v which seems to be at -14v, but this may be because there is no load on it [I'm guessing at this]
Windows sometimes reports "There maybe a problem with your RAM" afterwards, but Memtest+ 4 runs fine for a loop, and has run before for a night [will test this again tonight]
I am not enjoying this one bit.
What is the next step after running Memtest+ for 6 hours I wonder? Any other suggestions?
Thanks in advance!
