EVGA 790i Ultra SLI EVGA 9800GTX+ OCZ OCZ3N1800SR4GK PC Power and Cooling 860 watt WD Velociraptor 300GB Q9300 Ever since I built my computer I have had the occasional freeze from time to time, and no matter what I do I can't figure it out. I have posted this same topic on the EVGA forums and on the Nvidia forums, maybe you guys can help me out. Basically, my computer will freeze on random once or twice a day if I'm playing left 4 dead, warcraft 3, or call of duty 4. It'll freeze about once during a 20min video I'm streaming off of the internet (sometimes more during the episode, sometimes less) and finally it freezes A LOT if I try to work with photoshop. I have frozen once right after the BIOS posted, once after windows made it to the desktop and was loading my startup programs, and once in firefox loading an image from an email. I have never frozen in any stress test program such as 20 passes in Intel Burn Test, OCCT, 12 hours of prime95, or 14 hours of memtest (I have ran these programs numerous of times, have never frozen) I've never frozen in more intense games such as Crysis, Crysis warhead, Unreal Tournament 3, and alittle less intense, Aion, and Team Fortress 2 (which uses the same source engine as Left 4 Dead) I posted my BIOS template over at EVGA and tried every BIOS configuration there is. I'm an overclocker so the funny thing is I was able to get this "stable" at 1800FSB, no errors in the stress programs listed above. I also have water cooling so temperatures are not a problem. But for the sake of trying to figure this freezing problem out, I'm running at stock link/sync 1333. What I have done so far to try and fix this: Reformatted 3 times, twice with Windows Vista, Once to Windows 7. RMA CPU RMA Motherboard (3 times) RMA video card (twice) RMA Harddrive Bought a new Harddrive Tried a buddies power supply (same make and model) RMA Ram Bought new RAM Tried one stick patriot 1333 ram Tried ram in all slots Tried BIOSes P06, P07, P08, P09 Unhooked everything but my core needs (vid card cpu psu 1 stick of ram and hd) Tried stock cooling Bought an UPS Bought a new monitor Tried different mice and keyboards Added plastic washers to all of my screws Replaced the SATA cable 3 times That's all I can think of for now, I'm sure theres more. There has to be some kind of hint as to why it freezes a ton more in photoshop, than playing a game, and why it never freezes during more stressful games/programs. Thank you for taking the time to read all of this, I really hope I can find the problem. I'd like to upgrade and keep this computer for along time, but from what I'm seeing after substituting everything on it, it's going to be impossible to fix. I've built plently of other computers so I don't know why this one is giving me trouble.
Try increasing your vcore and vdram voltages, could have stability issues. check your cpu and rams maximum voltage limit and try increasing the voltages by about .1 or .2 I know you ran prime95 but should also try running ortheros.
My ram is said to work at 1.9 but I've tried 1.95. I've also tried my CPU at 1.45. It seems to be more stable with more voltage, as it takes longer to freeze in photoshop.
