Ok i have a tiny problem, evry once in a while my PC shows no intention to boot, since MSI has teh diagnostic LEDs they show me that the machine is stuck ast the early chipset initialization, if it passes this part ist hangs ant Memory detection, so I have to pull the plug ( restarting doesn't help), after that i get the nice error message CMOS/GPNV checksum error WTF??
I cleared the CMOS but it doesn't helps.
SO what to do?
Is that maybe a sign that my MBO is slowly dying?![]()

Could be the mobo but it makes sense to eliminate other things from the equation first. Firstly, set all o/c's back to defaults, always best when troubleshooting, voltages espicially as they can really do some harm. You may wish to try the latest BIOS followed by another clear (some pop the battery out for 2 mins) then reseting back to BIOS defaults. Ensure all cards (PCI, AGP, RAM etc) and cables are firmly attached, perhaps re-attach them or try running with just the essentials. If possible try each component in a known working PC. The problem part is likely to be one or more of; mobo, CPU, RAM, PSU or on the outside gfx card.
If your CPU is TbredA then it may simply be too much at 1.825mhz, the TbredB has an extra layer which is why they clock so much higher. Another thing to consider is FSB speed ... is it FSB or multiplier you're using to o/c? SiS745 was designed for 266FSB (2x133), some components really dislike o/c'ing and o/c'ing has always been a big weakpoint of SiS chipsets, you are certainly likely to come into problems going above 288FSB (2x144) as the PCI, AGP, RAM and IDE are all running pretty far out of spec. Your PC2100 is also designed for 266FSB operation and may not like going higher even with slow timings. Finally your 9500PRO SHOULD be happy with that o/c, it shouldn't kick in until Windows anyway but set it back to default just to help eliminate it. Did you severely stress test your system before settling for those o/c's?
147FSB (294 inc DDR) is pushing it a bit far really, the mobo uses a 1/4 PCI divider as that is perfect for the 133/266FSB it was designed for. At 147/294FSB your PCI is running at 37mhz (rec'd max is 36), AGP = 74mhz, AGP4x mode = 296mhz (rec'd max 72 & 288), RAM if synced is running 294mhz (PC2100 is designed for 266mhz), RAM if 4:3 = 392mhz, RAM if 5:4 = 368mhz and as for the IDE that varies on implimentation, VIA are picky but SiS should be better, though you may be pushing that a bit far too. Your vcore is a little high, Tbred CPUs are designed with a 1.65v max in design but up to 1.70v should be okay if the extra speed you get from it warrants the extra stress and heat put on the CPU. However you should find you get around 1.7-1.8ghz with only 1.50-1.55v. BTW the rec'd maxes are dependent upon specifics, with the right parts you can go higher, with other parts you'll be even more limited.
I'd rec you return to stock speeds (and voltages) for a while and see how you get on. If you get instability try putting good parts in there or your parts in another PC (one at a time) to try to ascertain the cause(s). Considering prices it would make sense to upgrade ...
