well back again looking for some help... my computer is hard locking randomly. at 1st noticed it when i was playing WoW. at random my monitors would show loss of signal then computer would completely hard lock .i had to hard boot it.. some days would do it several times others not @ all. I started to run stress tests to check hardware. Prime95 on CPU, Heaven, AvP, 3dmark 11 on video cards, Memtest86 on ram. zero issues passed all tests. also anti malware/spyware etc. tried another PSU i had laying around for a while it hard locked w/ that. gave same PSU to a friend to use and been working great for last several months for him.
after messing w/ computer for several months (4-6) i decided to take it to a repair shop to have a fresh set of eyes look at it. they had it for 2.5 weeks. ran several tests i did as well as some others. never a issue for them, even let them play WoW to see what happens. still no issues. they decided to un Prime95 w/ a HPU stress test @ same time didn't lockup. they told me if i wanted the to look further i said go ahead. but i got a call the next business day saying they were too "scared" of my water cooling on computer. so i picked it up....knowing what was going to happen when i got it home..
hooked up PC @ home and w/ in 1st 35m hardlocked 3 times. it also did a hard lock w/o any games. just on desktop w/ maybe pandora radio playing while i was serching for answers on web. being i checked alot i started to look @ Bios. making sure mem voltage etc were good. they were but one thing i did notice is my gauge inside my case is reading 4ghz for CPU speed. i have a 2600k which i have never tried to overclock yet, bc when i wanted to is when these issues started. in bios shows the stock speed @ 3.4ghz and my mutipler is correct.
i'm about to check myself into a rubber room this is driveing me crazy. i built this rig and worked great for 3+ years no issues. i can normaly fix problems but been working on this for so long i fear it's something stupid that i've overlooked so was wanting some fresh "eyes" to try to help me
