Videocard as the cause for program crash ?

Question

I have got an MSI mainboard and an MSI video card. I overclocked my CPU modestly (FBS 200 MHz --> 244 MHz) with the corresponding decreasing in HTT and RAM speed, and keeping the timings very relaxed, and turning off the spectrum spread. However, my game Half-Life 2 and Internet Explorer crash from time to time. If I overclocked my video card, this significantly increased the frequency of crashng events.
It got me thinking: probably, the reason for crashing is that the frequency of operation of the overclocked mainboard does not match with that of the video card. I searched the BIOS for the settings like "locking the PCI bus frequency", but could not find any.
What would you recommend ?

do not OC everythink in a same time..(keep VGA at stock parameters)
find out 1st max stable freq. for your CPU. (give vcore only when need, make test and ensure that its stable. watchout CPU temp during testing and ensure  its in normal range.)  look here for testing applications: https://forum-en.msi.com/index.php?topic=107133.0
I had kept the VGA at the stock parameters, while having overclocked my CPU from FBS 200 MHz to 244 MHz. I found out that if I put BSB to be equal 250 MHz, then the computer crashes and starts to reboot in a loop. Thus, I decreased the FSB to 244 MHz. Using CPU-Z, I found that at such an arrangment, the FSB:DRAM is CPU/7, and the memory frequency is 331 MHz, which is close to the stock ferquency 333 MHz. Perhaps, this is an explanation why I cannot go higher in FSB than 224 MHz. In fact, I was already asked on this forum to post the CPU-Z details on memory timings which I did, and the comments were that the timings were relaxed. I control the temperature of CPU with CoreCenter, and the temperature has never been higher than something like 50 CD when I was running the CPU overclocked at FSB 244 MHz.
I have addedd the details on my PSU into my signature.
I re-state my problem: when either CPU or GPU is overclocked, I get the game HL2 crashed often (something like 5 times in a 2-hour session). I have now returned both CPU and GPU to standard settings, and I will watch the occurence of crash. So far (2 or 3 1-hour sessions), there was no program crash. I will watch for longer.
