Question about Intel Motherboard
I purchased a new motherboard, CPU and RAM at the weekend. Replaced my ASUS MB and AMD x2 3800 with a Gigabyte GA-MA74GM-S2H and AMD x2 6000 with 2 x 2gb DDRII RAM.
Fitted the MB and chip, booted the PC and checked the bios values OK. However, as soon as it loads windows (XP home SP2) to the login screen, the system powers down.........power just cuts.
Things I have tried:
* New power supply
* New hard drive - formatted, started OS install routine, got to the point of loading windows, powered down.
* Removed all peripheral connections so only had Motherboard and HDD connected to power
* returned both MB and CPU to shop and exchanged as I concluded it must be faulty. Fitted replacement MB and chip - same again.....powered down.
* run the motherboard outside of the PC chassis
None of the above had any effect.
I can run the bios prog for an extended period of time. It's only the loading of the O/S which causes it to power down.
Any thoughts? I'm tearing my hair out here.......I feel like I've troubleshooted for everything.
usually it is over-current that will make PS_ON go high. However, the opposite is true: if not enough load draw, PS_ON goes high and never goes low. Not exactly certain about link to 12V2+2 connector, although same theory may apply.

If you don't already have a case speaker hooked up to the board, you might want to connect one since there isn't an on board speaker and you will not hear error beeps otherwise.
Also, if you have another non-phenom AM2 processor handy you should really update the BIOS to latest release. Many late model Phenoms will not work on motherboards that have earlier BIOS releases and you will not be able to post. You should then choose "Set Optimized Defaults" and save the bios without any changes then shut down (not reset). When you power on again it should post and you should be able to get into the BIOS.
A third thing you can try (after you get a case speaker hooked up) is using a cheap pair of ddr2-6400 RAM to get the board to post so you can get into BIOS and change the voltage to the correct settings for your RAM if it requires a higher voltage than the bios expects.
