I've solved the mysterious delete reset problem I had in the bios!

I slapped the USB keyboard in a different port on my USB hub.

No more resets when I press delete now when in the bios!

What's going on here and what can I do?

Seems like you might have a USB hub port thats going bonkers. Try connecting your keyboard and mouse to the USB ports on the mainboard.

Does the z68 (chip with v8 heat sink) on the motherboard get hot? I'm a bit confused here. On my board it seems to become very warm (hot to the touch) so I was a bit concern. From intel site the operating range seems to be up to 100C. Anyways I was a bit concern so I email asrock support and they said it should not be hot and should have a max temp of 35 Farenheit (which would be frigid) so I should return the board.

I am NOT using a dedicated gpu; but rather 2500k's as my gpu. This is also the only chip on the board that is extremely hot (cpu is around 35C - peak 60C when running prime95).

Here is my note and asrock response:
-
Also the chip labeled v8 (Z68) gets extremely hot (I would guess 70C or 80C but have no method to measure). Is this normal?

Their response:

When you mentioned extremely hot ,is when we recommended to return it , the motherboard chips does not get hot to the point the way you described.
the range is from 35 to 45 Farenheit .

Using my temperature gun (+/- 2% range) with the system idle in a case with the side panel off I measured 40.6c. (See Z68 E4 review link in my sig), I can well imagine in a closed case even with good airflow that temp rising to around the 50c mark. You have a few choices here really;

1. Remove your mobo and send it back.
2. It's very probable that the reason for your high temps is a poorly mounted "V8". You could remove the heatsink, clean off the TIM (which for stock TIM is actually quite good.. its no AS Ceramique though) check to make sure there are no "bumps and bobbles" on the HS base (if there is, simply sand them away with some sand paper) apply fresh TIM and remount the heatsink.

The latter of those options is likely going to be the fastest fix, albiet at some inconvenience. Just be aware doing the latter might void your warranty.

@ Users with eSATA / SSD issues: We are currently waiting on some devices to arrive. Once I know more, I'll let you know.

General Info;

I have suggested that the "Level" fan mode in the UEFI is replaced with a percentage method letting the user set a custom fanspeed between 25% - 100% for greater cooling to noise ratio control. Response is pending.
