hi everybody... after a 2 days stress session for my little 'puter (), here are my latest thoughts about it, but let me tell you that I've definately fixed all my problems

- put both graphic cards back in blue PCI-e slots. back to normal value under 3D Mark '06 (13467 points 1680x1050,4AA,Anisotrop.). with a better cables placement (replaced IDE and floppy cables from MSI bundle for rounded), no more temp problems, even if the southbridge and the heatpipe are still so hot
- CPU temp : 37 idle, 51 full (according to RealTemp 2.24). I put some arctic silver 5 instead of noctua nh-t1
- GPU temp : 46 idle (both), 63 full, and no freeze, bsod, etc... (using latest nVidia drivers 174.74 beta) after playing crysis for more than 2 hours
- horrible sounds : gone !!! there are tons of awful crackling sounds when I put the X-Fi in one of the 2 free PCI-e 16x slots. with my graphic cards in both blue PCI-e, there's still some place between them to put the X-Fi in the free PCI-e 1x slot. no matter which drivers I use (from MSI CD, from MSI website, from creative website, or from youp-pax), there are no more problems, so I'm gonna leave it here with official drivers
- I finally received my LG GGC-H20L which is my first SATA optical drive. I was curious about that problem that is sometimes happening with nforce chipsets and SATA opt drive. I tried to install both XP SP2 32bits and Vista SP1 64bits from this drive, and I didn't get any problems. also, I've never had to remove any of my memory sticks to install any of the OS. 4Gb all the time...

nothing else to say. I'm running a very stable and performant computer. sorry guys, but I won't report any overclocking attempt for now. I'm still too scared about it. my computer is exactly what I was hoping it to be when I decided to build a new one, and I don't regret any of the components... (this doesn't mean I won't post anymore. I'm staying with you all the time )

PS: before I forget, I'm running bios 1.16b
