This is quite weird, but anyway you can expect anything sometimes.
For the boot problem try these steps:
Advanced>> Hard Disk Pre Delay >> No
Advanced>> Peripheral Configuration >> Disable the eSATA Port.
Go to Boot Menu
Boot Menu: Advance
Boot Priority: Hard Disk Drive First
Boot to Removable Devices Disable
Boot to Network Disable
Boot to Optical Device Disable
USB Boot Disable
Boot USB Device First Disable
USB Mass Storage Auto
Now regarding the slow running applications:
Try the system with only one memory module:
Try the system with the two memory modules on different slots: (dual mode, non dual mode)
Repeat the steps above if you have three memory modules
Let me know how it goes.
Yeah you are right, if there is any problem with the new bios version, hopefully they will issue a new one later. But one more thing, when doing the tests, Intel always uses the memory which is on the Tested List.
So if your memory is not list, they wont even know that there is a particular issue with them, and thus even in the new future bios version, it may not be fixed.
Anyway, for now, it is wise to use the previous bios version till they find something on this luckily.
Unfortunately, i could not help you further on this, may be next time. I am always glad to help.
