Welcome to 7F. There is only one dump in your logs but looking at it I would suspect they're all the same.

[COLOR=Red][B]*** WARNING: Unable to verify timestamp for IOMap64.sys
*** ERROR: Module load completed but symbols could not be loaded for IOMap64.sys[/B][/COLOR]

Could not read faulting driver name
Probably caused by : IOMap64.sys ( IOMap64+1988 )

This is blaming an ASUS service. You have a lot of ASUS software installed on your machine and it would be wise if you removed it. Do that and test stability then report back.

thank you for the fast reply i had 7 or 8 dump files all with different caused by driver in the blue screen report but all with ntoskrnl.exe mentioned but they all got wiped when i formatted my drive and done a clean install I have now wiped all asus software but as the crashes are random and only on start up never when stress testing i can only wait and see again thank you very much for the help Im a bit of a newbie with BSOD trouble

Not a problem, upload any new dumps from any subsequent BSODs.
