powerbutton power lag and restarting

Asus P4p800 deluxe motherboard

Specs: Windows XP
My pc staretd acting funning. At first I would be typing and only every few words would type and I would get a pc beep like the keys were stuck. I reset the keyboard and that seemed to work. I didn't think anything of it. Later on, I put in sleep mode and the pc would go into sleep mode, then after 5 sec, would shut down, and restart. It gets into this loop of doing start up checks and then once it tells me it was shut down propertly and to choose an option and I click to start windows normally, or last good config, it proceeds to load windows. As it is doing that, it shuts off and then will turn on 2 sec later and keeps doing this. I can get into safe mode without it restarting on me.

Also, when pressing the power button nothing happens. After 3-5 sec it will power on itself, but pressing the power button wont turn it on that second, I have to wait 2-5 secs for it to turn on itself, the power button doesn't seem to work immediately.

I tried to go into safe mode with networking. When I did this it reset again. So I thought maybe something was wrong with the ethernet plug. I unpluged that and then restarted, it loaded windows fine. I noticed it shows my soundmax icon with a x through it, when moving the mouse over it, it pops up that no soundmax audio present. I do have sound though, so not sure what this is about.

After loading it up and then going into standby mode, That works now and will come out of standby without restarting computer. Plugging in a new ethernet cord, but not connecting it to anything caused the pc to shutdown and then turn on to restart.windows loaded normally after this, with cable still plugged into the back, but not to actual modem it loaded fine. Plug in cable to modem and interent workls fine. Tried standby and it shut the pc down like a hard reset like it has been doing. now keeps going through same loop as before. So I am not sure where to go now.

I can get into the bios as well. this is just too frustrating. ANY help would be appreciated

Eww, lots of issues there. Sounds like it needs a thorough bench
testing & diagnotics. Could be HDD, MB, PSU, RAM,
OS/software corruption etc.

Just another stupid saying...

UPDATE: repalced the power supply and all is back to normal. I am getting some different beeps in the bois start up and takes a little longer to go through it, but everything is running the same now. One thing that is not is my standby mode. It will quickly try to turn everything off and then come right out of it. I have made some changes to the settings and reinstalled drivers but still nothing.

I wonder if your ACPI settings in your BIOS might be disabled in
the BIOS? That is, instead of having ACPI ON where the OS
then controls power management, your ACPI might be OFF,
then BIOS power management settings control power
management.

Not sure what your BIOS settings are, do you have the Asus: P4P800 Deluxe, or Deluxe -E?

I couldn't download your MB manual (pdf) from ASUS website, the download is hanging.
