just built a new pc for my son-in-law. AMD64 3700 MSI neo4 mobo 1GB ram XP Pro sp2. Was working fine downloaded all updates and installed avg - ms defender - zone alarm etc. Transferred all data from his old pc and all appeared fine. I uninstalled my adsl software and took the unit round to his house. I plugged it in and the first sign of a problem was that the green light of the monitor went off after a few seconds. I then realised that I had heard no beeps. I have removed and checked the memory which is fine in my pc and the msi pci-e video card which also works fine in mine. With everything disconnected from the mobo except the power supply I get no beeps at all. At this moment I can only assume it is either the mobo connections from the psu [24 pin plug and 4 pin plug], the mobo itself or the AMD chip that has failed. When powered up all the fans run ie psu; cooler on top of cpu and small fan on the mobo. Could anyone suggest a way of determining which has failed. All suggestions appreciated as usual.
Not always the case, I know from personal experience, I spent hours one time trying to find out what was wrong with a PC that would not boot but all lights and fans etc were working, the last thing I tried, you guessed it, PSU, and it booted straight away.
brand new case with 450W psu - pci-e card does not have any power connectors and it works in my pc. I have just removed cpu fan and reseated it [I do not think it had moved] and am about to put the cooling gunk on it.
