beeps while pc's posting

this is my prob, when I boot the pc, I get a high low repeatative pitch, I replaced the video card, checked the bios, the only thing I see wrong is that the cpu temp doesn’t register…once windows boots It stays up for about 1 min before it shuts down any help would be appreciated

yeah it tells me that its a cpu heat issue, the heat sink is running fine…

If it doesn’t tell you the temperature, it’s likely the sensor is faulty therefor is shutting down the PC to ensure it lives!
See if you can turn off the temperature monitoring!
