A customer brought in a 21-a013w AIO PC that had a power related failure. The AC connector on the power adapter was quite charred. When I applied a new charger to the PC, the power LED near the power socket lit, but the computer would not power on. I called it a motherboard failure and procured a replacement (reclaimed), installed it, and booted it up. The PC did power up, but when the BIOS splash came up, it did so double on the screen and completed the boot with two desktops (mirrored) in a horizontally split screen. The computer functions fine with the exception of the double desktop. I've set aside the OS as a cause, as the split screen shows up as soon as soon as you power on. Any thoughts would be appreciated. Thanx

I cannot find 21-a013w in any HP site that I know of. Google shows a 21-h013w
Maybe that is the one?
If you used the original CPU then should boot using same HDD.
IF CPU is different on the board you obtained then the wrong driver is loaded.
Should be able to uninstall the old driver eg: intel GT1 or GT2 and scan for new hardware and get the driver for the newer or older CPU. You may have to uninstall the CPU using the device manager if new one is different.
**bleep** strange HP blanked out their on s.u.pp.o.rt number
