A friend of the family decided to "build" a computer and didn't go as planned. Apparently he installed Windows 7 and for whatever reason decided to replace the CMOS battery after. He may or may not have replaced the RAM too. Now the computer does not boot up. All I get is error 0xc000000e "the boot selection failed because a required device is inaccessible". I tried a clean install but as soon as I try to boot up from the cd I get error code 0xc0000017 ramdisk device creation failed due to insufficient memory. Any help on this would be appreciated. Windows 7 RAM: Corsair CM3X2G1333C9 (DDR3 1333mhz 2GBx2 Motherboard: M4N68T-M Power Supply: Thermaltake TR2 600W Power supply - 600 Watt Graphic Card (newly installed): Radeon R5 230 2GB HDD: Seagate 1TB Thanks.
