Blue Screen With Irql_not_less_or_equal Error?

ok my problem. at random times i get blue screen. sometimes blank and sometimes error codes. one error code i took a picture of on my phone says irql_not_less_or_equal top: 0x000000000000a then does a physical memory dump. i think this is common with alot of blue screen errors although im not to sure. there is no pattern to this at all. it happens at total random times. sometimes when running cpu for awhile and sometimes right at rebot before windows. usually when it does happen it happens alot. and when it dosnt happen it dosnt do it at all untill next rebot. when it does happen and i rebot i hear my hard drive click when it comes to the S.M.A.R.T. capable but disabled part. made me think i had a bad hard drive. so i tried reinstalling windows to make some partitions. when i boot totaly from xp cd i get blue screen after it loads Setup files and says Setup is loading windows. get this everytime. once i have got to where it states Press enter to install windows xp but my cpu froze. so i tried installing windows onto my rather new 100 gig hd that i have never had any problems with and the exact thing happens. Things i have done to try and resolve this issue other than what i stated above are changing ide cables to new and taking out 1 stick of ram at a time to see if maby one of them could have gone bad. still same results.
