Question about Motherboards
I have a p5w DH Deluxe mother board and my PSU went bad overnight. After replacing the PSU, the motherboard now powers up whenever i turn on the PSU, but doesn't actually boot. the power switch seems to be inhibited, as i cannot hold it in to power off the computer and the problem still occurs after i dissconnect the switch from it's pins. i am suspecting a problem with either the mother board or my processor and was caused by dirty power as my PSU died. i have a temperature sensor on my heatsink for my CPU and it actually measures a decrease in temperature when the fans are active, which leads me to believe that the CPU is not receiving any power. i need to find a way to check the MB and CPU without actually removing the CPU from the MB... my heatsink is kinda a pain to get on and off, and i can't afford to replace both on a whim... i need to know what is causing it before i can move forward. also, this PC is used for my business purposes, so i need it repaired quickly. thank you.
You might try clearing CMOS as it may have been corrupted.
Had a similar problem when I was testing alternate CPU were board is "auto configure". Worked well when stepped up, but not down and then didn't want to boot. I would be looking very closely at "ALL" the capacitors on the board for swollen or popped cap's possibly from previous power supply defect!
Just because it turns on doesn't meen it will work.
When you say your PSU went bad over night it's a bit speculative since the problem likely started sometime previous. The real question is now how much damage and did you visually inspect everything? If it was off prior to discovering the dead PS you likely don't have CPU damage. You may also have chassis intrusion detection which could also lock you out!
Power switch should be related to bios settings for standby power management options. You can in most cases preset for soft off. sleep mode, standby.
One other suggestion; you might make sure your power supply is sufficient power for the load of your system!
Hope the information helps though I specialize more in mechanical controls but make sure you have power supply unplugged and discharged before you start playing and exploring the board!

Test your PSU or replace it if your power supply units fan
is not working your PSU is faulty
One bad lead can cause a computer to continue on a cycle or
to shutdown or fail to detect/ boot up a computer hard drive
Test all leads that attach to your hard drive including
the leads from your
"((motherboard to your hard drive))" make sure they have a secure connection and
are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error hope this helps
