Just Replaced My ASUS Motherboard And Now Random BSODs!!! HELP!
Hello. Replaced my motherboard with the same make and model under a warrranty program with ASUS. The motherboard is the P5Q. I did not have these issues at the last moments of using the original P5Q before sending it to ASUS. I noticed this issue right from the start after connecting the necessary hardware components to get the system running (motherboard, power supply (BFG 800W), processor (Intel Core 2 Quad Q9550), processor heat sink, 1 DVD burner drive (LG brand), and a hard drive (WD Caviar Blue 500GB), graphic card (ATI Radeon 5670), memory (installed 2 sets of Corsair DDR2 XMS2 2 x 2 GB modules or 2 TWIN2X4096-6400C5 for a total of 8 GB), mouse and keyboard). I used the same originally installed Windows 7 SP1 64-bit with the exchanged ASUS P5Q motherboard. I even thought it may be an issue with the Windows 7 64-bit installation with a new motherboard, so I did a clean install with Windows 7 64-bit again -- Still the same issues. The BIOS was flash updated at the ASUS testing to the latest version. I installed the latest motherboard drivers downloaded from the ASUS website.
I notice this issue happens randomly and most of the time when I am "Shutting down..." Windows 7 64-bit. Just after the "Shutting down..." phase ends, the screen for about a split second flashes a pixelated screen then the system does completely shut down.
Othertimes and more frequent when I have the system up and running, the system instantly freezes up for approximately 10 seconds. This happens randomly and I would say approximately 1-2 times per every couple of hours. The curser cannot be moved for 10 seconds and then the screen quickly turns black for a few seconds, as it flashes quickly and then the desktop resumes. Following the system freeze, I get a message above the notification area in the bottom right of my screen stating, "Display driver stopped responding and has recovered. Display driver AMD driver stopped responding and has successfully recovered.". Windows 7 Reliability Hardware Error reports it is a "Video hardware error" with the program event name "LiveKernelEvent" with BCCode of 117. I recall for two of the occassions that I was closing a maximized window when the system froze and moving the scroll bar down when it froze. I have used the built in Windows Snipping Tool and have noticed when the screen is being captured, the freezes like above too. I have also noted that response times when clicking on links can take a few seconds in instances that was not normal before with the original motherboard.
Additional notes:
1. No obvious error window messages posted on screen when issues develop except for the graphics card error messages that appear in the noitfication area.
2. I noticed if I enabled Aero in Windows 7, the crashes seemed to happen (randomly a couple of times per hour) more frequent than using Windows 7 Basic visuals.
3. File system issues? Ran sfc /scannow -- no issues at the conclusion of the scan.
4. Possible memory issues? Ran Memtest86+ v.4.20 (latest version, ran for 7 passes for 12 hours 15 minutes) and Windows Memory Diagnostic (from Windows 7 Repair Disc) -- no errors reported.
5. Let me expand on the memory issues. I noticed when I removed 1 of the 2 sets of the memory modules from the motherboard (Having only 4 GB total), after the first system reboot after the partial memory removal I get CHKDSK to run automtically after reboot. I let it run to the conclusion and I see it fixes many errors after finding system files corrupted. However after the fixes, this issue still lingers with 4GB. I restored my memory back to 8 GB.
6. Possible power supply issues? I bought and tested the same hardware with another comparable power supply. I used a A-Power 750 W new power supply thinking the amps and voltages were becoming weaker with my older one ultimately causing power loss. The same issues still presented themselves.
7. Let me expand on the possible power supply issue. I have kept records using the software CPUID HWMonitor. It reports electical and temperatures of key components of the system. I notice with this exchanged ASUS P5Q motherboard that the CPU VCORE voltages and the DRAM voltages are lower than the original ASUS P5Q motherboard when at idle.
Original ASUS P5Q CPU VCORE Range (min./max.): 1.22 V - 1.22 V
Replacement ASUS P5Q CPU VCORE Range (min./max.): 0.94 V - 0.95 V
Original ASUS P5Q DRAM Range (min./max.): 1.46 V- 1.46 V
Replacement ASUS P5Q Range (min./max.): 1.20 V - 1.21 V
Any issues here related to my issue?
8. Possible graphics/video card issue? Uninstalling the latest graphic/video software downloaded from ATI thinking the installed ATI Radeon driver or software could be the issue. When uninstalled, the system used the Microsoft drivers. Same scenarios as above regardless if the ATI drviers and software were installed or not.
9. I ran my Norton Internet Security 2011 and also the popular Maywarebytes' Anti-Malware softwares as a full scan. No malware detected.
I have included below images of the minidump files from my Windows 7 64-bit using BlueScreenView software to aid in the determination of this/these issue(s). I notice that the driver ntoskrnl.exe has caused this issue in most cases. I see the address ntoskrnl.exe+80640 was involved in most cases too.
Please reply with possible solutions to my issue.
Thanks!
