Having nothing but trouble with my new ASUS P8Z68-V board. About to RMA it, but wanted to see if maybe anyone had any ideas first.
i5 2500K and Corsair CMX8GX3M2B1600C9 (DDR3-1600 1.5v) installed.
First issue I noticed was legacy keyboard support not working. Even without any other USB devices plugged in the USB keyboard (and I tried 3 different ones) would sometimes not work.
Next issue the motherboard sensors seemed a bit goofy. Using Open Hardware Monitor, I noticed that sometimes and extra CPU temp sensor would show up. At first I figured it was the program. But it also seems like my CPU fan will slow down when this extra CPU sensor shows up, and so my real CPU core temps start rising due to the low CPU fan RPM. Made me afraid to Prime95 the motherboard because of this.
I dragged some icons onto my desktop. Later on I realized this icons were gone. If I look in the \Users\...\Desktop\ folder I could see those icons, they aren't hidden, but I don't see them on the desktop. Not sure if it's related to my motherboard issue, and didn't think much of at the time.
About every 2 or 3 reboots some of my USB devices would show up as new hardware again, even though they hadn't been unplugged. Even had one of my SATA hard drives show up again as a new device.
Sometimes one of the SATA drives wants to run a chkdsk when Windows starts up. And a large number of orphaned files are found (or so say the dialog). I've been using the drive with my previous motherboard and believe it's fine. And what is weird is every few reboots it'll come up again and again claim to find the exact same errors. Seems peculiar.
Also when I try to run some recently downloaded apps from a different hard drive, I get an error that the EXE file is not a valid WIndows program. If I redownload the file, it works fine. Seems curious.
And then things finally went south when logged in after a reboot and got a message from ASUS AI that there was an access violation error. I click OK and the app close. I tried to run another app and got another access violation error. I tried to uninstall ASUS Tools and got an Access Violation error. Some apps seem to work, while some don't. So I tried a system restore back a few hours. And still had the same problems.
So I thought maybe some of these issues are related to a bad OS install. I booted from my Windows 7 DVD and tried to reinstall, but for some reason not all my drives are showing up. However the one I need is there, so I tried to proceed only to get an error that I can't install WIndows do this drive. I deleted all the partitions on the drive and tried again and still can't install WIndows.
*sigh* Oh crap. I can't believe all these issues I'm having. I put my old P45 motherboard back in, with all the other same hardware (plus my Q9550 and DDR2 memory) and everything is back and running smooth. No USB issues, no more issues with any of my hard drives.
So is it just a bad board. Anything I could do?
The board has a BIOS version of 0301. I reflashed that same BIOS (it's the latest on ASUS's website). I reset the BIOS settings to factory defaults.
