I recently purchased a second hand pc, i was told it had problem starting up, and it keeps rebooting, got it home plugged everything in and now I can hear the HDD working but the MB doesnt pick up the monitor or anything attached. I am assuming the MB is stuffed and I am looking to by a new one , not wanting to spend much. the current MB is the ms 7060 with SIS964 chipset, the HDD video card, mem etc all appears to be ok. is it possible to replace this board or is it worth getting the ms 7104??? thanks.
