HokieRif Posted July 11, 2006 Posted July 11, 2006 Here's a softball for the forum... I recently installed a second 7800gt in my system and everything appeared to be in good shape since the install - Windows XP runs fine, Aquamark and 3DMark ran beautifully, and I played around with a couple games (Half Life 2, C&C Generals, nothing too taxing). Last night the fun begins when I finally install CoD 2 and I crank all of the settings up to the max and enable the "SLI" feature in CoD2. While playing straight for 5-10 minutes I started to get some warnings from MBM5 saying my GPU and GPU ambient were beyond the threshold (it was set at 70c) - I ignore it and keep going... a few minutes later the whole system shuts down. A few seconds later I power the system back up, it gets to the BIOS screen, and it powers right back down. So, thinking I may have a heating issue, I wait some more, power it back up and it gets all the way to the Windows startup sequence before it crashses. I wait another 5 minutes, try again, and I'm finally back to Windows. Long story short, the above sequence continues to happen and I suspect that I'm either running in to a cooling problem with my PSU (I kept the case open during my run earlier this morning and it managed to go a few minutes longer ~15 min.), or the addition of the new card has pushed the PSU to it's power limits and I need a few more watts to make this setup happen... So, my question to the group is am I thinking along the right path, and if so, do I place a house fan next to the psu to help with the cooling or do I need to look at a new PSU based on the equipment in my sig?
