I have a 9010 SFF that was working fine, except that it would not install the Windows 10 Anniversary Update. Repeatedly, about 30% through the update it failed with a BSOD. I tried several times.
Somewhere I read that the BIOS might need updating so I headed over to DELL support. I let the website automatically detect my system and it found a recommended BIOS update, version A24.
I initiated the BIOS update from the website and it seemed to run successfully but when the PC rebooted it hung half way through POST.
On a second attempt to start the machine - nothing - no display, no light, just will not start.
I tried clearing the NVRAM as indicated on the DELL website here: www.dell.com/.../SLN284985
I tried both the RTCRST jumper method and the battery removal method.
The result - it now continuously reboots but still no POST, no display, nothing.
I should add that during the original BIOS update, the PC had a Quadro 600 graphics card and a LSI 9200-8e SAS adapter card inside. They had both been working faultlessly and were removed when I tried to reset the BIOS NVRAM.
Any suggests on what next to recover my "bricked" desktop?
The CMOS could be corrupted meaning replacing the motherboard. During this no POST, what are the states of the power button LED?
Initially, nothing happened at all when I pressed the power button.
But since I reset the NVRAM, the orange power light comes on briefly, then it goes off and the machine is quiet and nothing more happens.
If I leave the power connected, after a little while, the machine tries to start again and the same thing happens - whirr of fan, DVD light flashes, power light flashes orange, then lights and fan go off - nothing.
I'm guessing that you're right and only a new motherboard is going to fix it.
