A new problem with my Z97-A MB. after turning on computer and within 15-30 minutes i lose user control. For example the keyboard will not respond and the video will not refresh. I have to reboot at this point and If i continue to use the computer it will continue to work but if i leave it alone for 15-30 minutes then it becomes non responsive. What should I start to look for? Asus suggested i flash it with the most recent BIOS however the problems remains. thanks

Running windows 7 Pro..

No hub or KVM switch, computer connected to a home use router and then to a dsl modem.
What the rep from Asus told me to do was also to reload my OS. This I am not convinced is necessary.
I have run a couple of speed tests(aei.ca speed test) and it is normal for the connection I have....until the computer becomes unresponsive within 15-30 minutes.
I am using the lan port, the SATA ports plus several USB ports.
I looked in device manager and found a yellow flag on one of the entries for network adaptors. I deleted this yellow flagged entry and it has not come back even when I scanned for new hardware.
I forgot to add that if i actively use the computer, surfing and opening and closing windows the computer will function correctly.

hmm, so I assume that you're running the latest possible drivers for the board's chipset? you can get those from either Asus or Intel ARK (the latter might be a bit trickier since Z97 is EOL)

I've run into similar issues where it ended up being a bad stick of memory. I would start by clearing CMOS, using default BIOS settings, and using just a single memory DIMM while you try and troubleshoot.
 
You lose control or the computer crashes?

So under active use it doesn't freeze, but if you let it idle it will freeze?

What if you turn off sleep/hybernate/turn off screen/ turn off harddisks in power management settings?
 
What happens if you leave Task Manager open, and look at the Disk 0 graph, or the CPU graph (make sure to select the options to "show as logical cores", and "Show kernel times").

I had something similar happen to a system of mine, CPU would stop, Disk 0 would go to 100%. Either Win10 was remotely imaging my disk over the internet (who knows what kind of spying capability that they really have in there), or I had some sort of SATA error, that hung a disk access, and then from that point on, Disk Access for Disk 0 was basically at 100%, because no further requests could go through.

The mouse would move for maybe a few seconds, as would the CPU graph would update a few times, then everything basically hung. No BSOD.

Never solved that problem.

Edit: It wouldn't manifest itself right away, it waited a little while after boot, after the system was running for like 10, maybe 15 minutes. It sounds kind of similar to what you're experiencing.

Edit: That was with Windows 10 (a few versions ago). I see that you edited your post to indicate Win7 Pro. I haven't heard of this problem happening in Win7 (Pro or otherwise), but maybe...?

That is the problem i am experiencing. As long as the the compyter is active it works just fine. I ran a benchmarking program called Performance test and it showed no issues. I will try your suggestions.

It is a crash in a way of course except that is not dramatic like a blue screen....

I think i found the issue with the computer shutting down. There was a lot of dust built up on the cpu fan heatsink and the CPU was overheating. Once I get the dust blown out I will see if it is stable.
