Liquid cooling still requires a good, thin thermal paste application between the cooling heatsink plate and the cpu.. If it's separated, or cracked, then cooling doesn't get done. What kind of temps are you getting when you check internal temperatures.
As to it possibly being a RAM issue, try removing all RAM except for one stick.. Place the one stick in the #1 slot and run the computer.. See if it causes a problem. Switch RAM sticks and slots till you can identify if the RAM or the slots are faulty.
Occasionally, it's not hardware at all. Try running Chkdsk (place CHECK marks in both boxes of the Chkdsk options window) to fix minor file and sector errors and optimize the hard drive. After this, run Defrag to fix other small minor issues.
Hope this helps.
I have a 3 year old computer running windows 7 that keeps restarting on its own and I can't figure it out. I am fairly good when it comes to computers but this one has me baffled. I checked that all cables are properly connected and it restarts each time I boot the computer but never right at the same time. At first it takes awhile then after it restarts the time between is less and less. I had this issue before and thought it was the ram so I replaced it and it worked for about a week then it happened again. So I thought it could be the slot I was using for the ram so I changed that and thought it fixed it and again it worked for another week then started up again. I've already tried system restore and removed any files that I didn't need and even now when trying to use the windows disc to repair it's restarting. Before when I had it in safe mode it also still kept restarting. I've run numerous virus and malware checks last week so I don't think it's that. I also just finished cleaning it out two weeks ago with a compressed air can so it's not that. I don't think it's the power supply as it's a corsair 700 and the entire computer was built for me 3 years ago and tested. I don't think it's overheating either since the CPU is liquid cooled. Suggestions?
