Hi,
Recently I got a blues screen crash and on reboot I get a flashing cursor in a black screen at top left corner of screen. Prior to that I got a couple of other BSDs which I couldnt pin down to anything in particular. Unfortunately no crash dump file was saved for unknown reasons (dumps are enabled).
It seems to be something to do with the motherboard, as even with nothing attached except a bootable usb flash drive which works on other PCs, I still get the cursor.
Before testing with a usb drive I tried a bunch of stuff:
-tested power supply to hard drive by powering up hard drives using power supply then connecting them via sata adapter to other PCs. The drives can then be read on the other PC.
-changed ram sticks and slots
-tried different sata ports and 6g sata ports on motherboard
-cleared CMOS, reset BIOS, remove and put back battery, switched to other BIOS (the motherboard has option of switching between two onboard bios).
-completed BIOS flashback
-disabled all onboard devices and tried with BIOS configures for IDE.
-Tried on board j-micron sata port.
-tried with other video card and other video card slots
At boot the motherboard LEDs light up as normal and then go off as they should. They do stall a little longer on the 'boot device' LED though, and 4 very faint beeps coming from the board (not the drives) which dont sound like the normal loud POST beep which indicates no CPU fan is connected (I'm using a fanless heatsink)
Any drives attached are detected in BIOS in the 'sata configuration' section and in the 'boot devices section', but regardless, after POST I get the flashing cursor.
I recently switched to an SSD from mechanical. Perhaps the sata controller got overworked? Would that also cause boot from USB to fail as well? Thanks for any suggestions.
