partition repair-- startup repair failed: Error code= 0x490

I did the windows recovery several times choosing option 1 one partition, then 2 and 3.  Did a re install with recovery disks, it starts and says setting up for first use, and checking video performance and it turns off, now i have the following messages;  file: \boot\memtest.exe  status:  oxcoooooof.  Info  The selected entry could not be loaded because the application memory is corrupt, and

 System Disk= \Device\Hard disk 0
window directory=
auto chk run=0
number of root causes=1

then it runs tests and then it says 

root cause found

No OS files found on disk

Repair action: Partition table repair
Result: failed Error code= 0x490
time taken= 13276ms

So what now?

Please and thank you
