Today I took my GPU out to reapply thermal glue to the heat sink, prior to this I had been booting fine.
When I placed the GPU back in I'm met with 'Disk boot failure, insert system disk and press enter.'
I booted from hard disk from the BIOS with no luck, I checked all the cables and BIOS battery, with them all being okay as far as I could see, and with nothing important on the computer, I decided I'd just boot from a windows disk and re-install, but beforehand I decided to do a startup repair wherein the root cause was
"A hard disk could not be found. If a hard disk is installed, it is not responding".
And I have nowhere to install a fresh copy of win7 onto.
Iunno, I did the same thing with my GPU as I always do when re-applying thermal glue. No variation. Anyone encountered anything similar?
I'm at a loss. Read through a fair few threads with none really having a fix.
