Arcolite Posted June 5, 2011 Share Posted June 5, 2011 The last two weeks I've been getting the odd BSOD followed by POSTing failure direclty afterwards which I can't for the life of me pin point where the problem is. It started about two weeks ago when I installed a USB Laser Printer onto my machine. Within an hour of that I got my first BSOD ever on this machine. I immediatly removed the printer and uninstalled the drivers hoping this was the cause. However the blue screens have stayed with me. They aren't daily and follow no pattern. They can happen while gaming, web browsing or sometimes even while the PC is just idling. Sometimes it's just the one, sometimes it'ls multiple back to back. All of my components which are listed in my profile are at stock and have never been overclocked. All BIOS settings are as default straight out the box which has worked perfectly since August 2010 when these parts were purchased. The only hardware change recently aside from the printer was to switch from a 5850 to a 6970 at the beginning of April. As it was ATI to ATI I didn't reinstall Windows but I did uninstall ATI software and run DriverCleaner before reinstalling drivers for the new card. It ran fine for a month before the first BSOD. So far I've tried the following to track it down: Upped the RAM Volts to 1.65v which they're rated for rather than the 1.5v the BIOS gives it by default and checked the the timings are correct.I've left memtest86 running for over 12 hours and found no problems with my RAMI left Prime95 running for over 12 hours and no BSOD occured.I left 3D Mark 2011 running on a loop for 6 hours without a BSODRun IntelBurnTest Multiple times without a BSODRun FurMark BurnIn without BSODMultiple AV Scans to check for nasties lurkingMonitoring Temps with CoreTemp and MSI Afterburner (all fine)Bought a new PSU just incase it was the PSU failing - which didn't solve itUpdated the Motherboard BIOS to the latest version I can't replicate the problem through stress tests and I've updated every driver I can find! It's really starting to frustrate me. It'll be fine for days and days then out of the blue for no reason it'll blue screen. After the blue screen I'll have to switch it right off for a minute of so before it'll post again. At which point the ASUS Bios will say "Overclock Failed" even though there is no overclock....unless it's doing it itself!! An example of some of the BSOD's...

I left the machine running over night and went to bed only to find that it had again blue screened while idling. All drivers have come via Windows Update so there shouldn't be any issues there and I haven't installed any software yet. This install is completely vanilla. The bluescreens from last night were...

Just incase it is the sticks, or just incompatability, I'm currently running just two and seeing how it goes. What confuses me is how I can go from a completely stable rig to this flakey machine through changing just a GFX card and installing a USB printer. I'm really struggling to proove where the fault is! I can't force the bluescreens to happen nor can I diagnose the faulty sticks, if they are indeed faulty. Memtest comes back clean every time and stress tests cope fine. It's just a case of waiting for something the might not happen...very time consuming and completely random. Annoying :P Link to comment Share on other sites More sharing options...
