My 18 month-old MSI 8800GTS 320MB OC has started to go on the fritz. It's been intermittent blanking out for 5 to 30 seconds or more (needing reboot). Neither DVI out channel works correctly, and the cable is good (it's working fine with the motherboard video out).
Even putting the fan to 100% and taking off the top of the case with a cold fan has no effect... it's not really hot on the GPU board, and the exhaust is not hot. In fact, the temps are only around 50C or so.
So, I filled out the RMA tech help page on the MSI website... and we'll see how good they are at honoring the 3 year warranty. Hopefully "shipping and handling" will be reasonable. I don't think they will ship to my FPO AP PO Box, so will have to have it shipped to family, and have them send it on...
UPDATE: MSI approved an RMA. They don't ship to PO Boxes (like my overseas military address), so I'll have the repaired unit shipped to a family member, and have them ship it over. Updates to follow.
