Blue screen - WINLOAD.EXE corrupt or missing

[UnitedAs1]

Ok so yeah I have installed 3 clean copies of vista64 on to 3 seperate hard drives and they all come up the same with a blue screen error at first "memory dump" and then later i get WINLOAD.EXE corrupt or missing I then go on to put the repair disk in and it will work fine for a few hours but then it goes back to WINLOAD.EXE corrupt or missing, I have checked and its there,

and now my computer just seems to get stuck in POST or when windows is loading.

Is this a hardware problem or software? is it best to just install windows7 over vista?

If you need anymore info let me know i will see what i can do,

Please help

Thanks In advance

Have you tried the CHKDSK utility??

Are you sure you have a 64 bit machine?
