Hello there, Hopefully you guys can help me. I have a liquid cooled Pentium D that works amazingly. I changed the liquid coolant in it last week and all was fine. Then I go to snap some new ram in and when I boot the next time my PC shuts off. So I took the new ram out and put the old stuff back in. I go to boot and bam shuts off! So I let it sit overnight. Boot the next morning, runs for 5 mins and shuts off. A friend told me to look at my CPU temp in the bios. I watched it go from 50oC to 115oC and shut its self off in like 1 minute. I even have the side panel off of my case and it keeps doing that! The liquid coolant is flowing through the tubes. And it is that hot. I was in disbelief so I went poking around with my finger. Yeah, it was hot haha. Blister time. Any ideas on how to keep my PC running? It's not overclocked. Ross

How about going back to standard air cooling?

Since this problem cropped-up after a liquid change, you may have done it incorrectly. There maybe an air bubble trapped. Bleed the coolant of air. Plus, is this coolant, the proper one? There are no kinks in the lines? Seems odd that the problem happens after a coolant change. -----Willy
