This is my first post. I have to say that this is an amazing forum!
I've been having a strange issue of late with my machine. I recently returned from 2 years in England and brought back with me a system which I've updated to the specs listed in my signature. The updates consisted of:
Changed AUS A8N SLi Deluxe mobo to DFI CFX3200-DR
Changed 2 x XFX Geforce 6800GT for 1 x HIS Radeon x1900xfx
Changed AMD Athlon 64 3800+ Newcastle to AMD Athlon 64 x2 4400+ Toledo
Changed AMD HSF with Ninja Scythe & Nexus 120mm
Since I made the changes, the machine has been freezing/hanging and rebooting (very inconsistently). Sometimes the machine will just freeze, and won't reboot. Other times it freezes and then reboots. Sometimes I can run the machine for days before it happens. Here are the things I have done to try and solve the problem:
Enabled manual forcing of BSOD (because it doesn't happen by itself), but unfortunately the keystroke combination doesn't work when the machine has frozen and hence I can't extract any form of memory dump and I can't point the finger at a driver.
Made sure that all my drivers are up to date, but one thing I have noticed is that the ULi SATA controller doesn't appear in the device manager (I have many ways to get it in there, but all I can see are the two separate HDDs listed, no controller).
Stress tested the HDDs with no errors.
I have run memtest86+ for 10 hours with no issues being reported.
Disabled my wireless network card to see if that was the issue, but it made no difference.
Stress tested the CPU overnight using SuperPI, Prime95, SP2004. No issues reported, and no crashes.
Removed antivirus software and firewall software to see if this caused the problem, again this made no difference.
Monitored CPU temperatures to see if it could be an issue with heat, but rarely do the temps get anywhere near the levels required for the system to become unstable.
I'm starting to get to my wits end, and I'm not sure where else to turn. I haven't overclocked the system, or done anything to improve its performance. Have you guys seen anything like this at all before? Is there any chance you could please give me some advice as to how I might go about tracking this issue down? I plan to do the following when I get the chance:
Install WinXP x86 to see if the same issue happens outside of my WinXP x64 install.
Remove software such as SetPoint which could also be causing issues.
Run memtest to see if there are any issues with 64-bit memory addressing.
I have a friend who has said that I should check my memory timings or somesuch, but I'm not sure what that means. I'm a coder by trade, so I'm fine with anything sotware-based and usually am fine sorting out hardware. I haven't been able to speak to this friend of mine for a while and would ask you techies to point me in the direction of how I would "fix" memory timings please
I have attached a few screen-grabs of the stuff listed in CPU-Z, just in case you find that of any use. Please let me know if there's any more information I have missed that you might need.
Any help would be greatly appreciated. I look forward to your responses.
