The oddities of my computer issues (random restarts)

ok starting the from the beginning ( last week Tuesday)

Came home to find that the computer is booting but no display showing up. Open up my computer to find the half the transistors to be blown (open, the inside of the fibers coming out. So i replace the broken 7600gs with a 9400gt. and it seem it was all good.

late Sunday night, while playing some games (wow/mass effect), the computer randomly shutdowns. reboot up, then try to load the game again, automatic shutdown upon loading into a town for wow. Ok so i thought my wow was bugged so I try a game with less demands of power, warcraft3 (only low game i have) still shuts down. So i go for the first thing that was change, return the 9400gt and replace it with a new one. put it in same problem, check my power supply cause that what seems like it the same issue, to find the amps isn't high enough and that it was border line with its maximum efficiency so i went and replace it with a ozc 600w slientXstream.

boots up fine seem like it worked, load a game and crash again. The added bonus is that it would now crash doing normal operations (surfing the net). REclean the computer and place new thermal cooling on my cpu (thought it was overheating) still the same issues.

the question comes down to this, do i have a bad cpu or a bad MB cause im down to only enough cash to replace one of them and I'm leaning to the MB

[edited] I have also ran a mem test and it shut down during that (while it having no errors)
ran a stability test with no issues
ran a video stress test it sometimes crashing

 

Sorry for the double post but it would not let me edit the post.

I found my issues and fixed it. There was a shortage somewhere on my MB( my guess is where the pci-e slot is at) I just replace it and it is acting all good agian.

 

Most likely this is an overheating situation. Itunes, RealPlayer, Windows Media player, etc. require a lot of processing power to decompress and decode music files, which can cause the system to get hot.

If your CPU is running at over 60 degrees you might be at risk of burning it out. Some systems shut down automatically when the temperature reaches an unsafe level.

Every few weeks I open my system unit and clean the fins on the heat sink that sits under the CPU. When they collect dust it restricts the airflow and prevents proper cooling. I just did that on my system and the CPU temperature dropped by ten degrees!

Download the free Speedfan utility and it will tell you the temperature at which your CPU and hard drives are running.

Hope this helps

 

nope it was actually a random short that was on the MB when the 1st video card was broken. It stop occurring once the MB was remove and replaced
