His old graphics card ASUS dual cooler 560 series, I think ) To replace a 3yr old Dell Alienware that was failing.
Build went well, booted up fine.
Once it was all running, and he'd restored his backed up files from his old computer, he wanted to have a look a a gentle speed up.
First tried CPU Level up in BIOS. Clicked on 4.2 level, and when it rebooted, it got stuck on the BIOS logo screen, and would not go beyond. Just sat there. No response to Del or F2. No response to turning it off or on. Tried the reset button on the MB. Got stuck at code 64 (something to do with CPU.) moved memory around, disconnected HD and SSD... nothing seemed to work. Reset the CMOS; took the battery out. About to give up, when after removing all the usb stuff plugged in, it finally restarted.
Had to rebuild the RAID, since it didn't recognized it. Reinstalled again (he has good backups.) Everything running fine on defaults.
Today he's looking into AI Suite 3, not resetting anything ... but had it run the fan opt ... on reboot it was stuck at the logo screen again. Turned it off. I was at work... when I came home and turned it on, it booted fine. In AI Suite, temps at 29 - 30 degrees for CPU and MB.
Looked at the 4 way optimization, and clicked go ahead ... and it seemed to get stuck at the logo screen after rebooting. We waited several minutes, thinking this was part of the optimization, and then, with no response to keyboard, and with a dread feeling, hit reset a few times. Nada. Tried turning it off and on, and after doing that a couple times, it restarted (whew) .... and came up in AI suite in what seemed to be third stage of optimization (not quite sure about that.)
And ... now at 4.2 MHz ... so he's pleased about that.
Question, after all this ... is it supposed to sit at the logo screen for minutes at a time after hitting the CPU level up, or running AI Suite? Or is there something haywire with this MB?
Happy to provide more details if I can..
