If the ICH chip (btw the P5P800 uses ICH5, not ICH6) had failed I'm not sure the computer would still boot. Asus usually makes good motherboards but maybe someone more knowledgeable than me with the hardware will know more. There seems to be some problem with ICH5 and the front USB ports so try to use the rear porst instead and see if it helps.
BIOS updates are most often used to add support for new CPU's and more RAM brands. What's your BIOS revision (should be written in some corner of the BIOS screen) ? I don't think updating the BIOS would change anything but you can give it a try if you wish. The latest BIOS for the P5P800 is from december 2005 anyway. Sometimes you can update it within Windows, else borrow some friend's floppy drive.
Your CPU temp is fine now, it's often higher in the BIOS than in Windows, either because it's using a different sensor to monitor the temp or because the CPU usage and frequency is lower in windows when the computer is idle (if speedstep is on it'll reduce the core speed to reduce the power consumption when the computer is idle). Use Asus PC probe instead of everest to monitor your temps and voltages, obviously everest doesn't use the right sensors (if the 5V line really was at 5.6V the computer would already have crashed). I'm not sure you can trust the 25°C temp from PC probe though, seems pretty low for me. Refer to the BIOS when in doubt, a 40-45°C or lower temp in the BIOS is ok.
All devices in the device manager look ok.
An overheating CPU can cause freezes like the ones you encoutered but there seems to be another problem if your computer froze again last night. See if there's some error in the event viewer at the time of the screen freeze. Also make sure you've cleaned the dust out of the video card fan/heatsink.
Right-click my computer => properties => advanced => settings under startup and recovery => make sure "automatically restart" is turned off. Then go to the c:\windows\minidump folder and see if there's some recent .dmp file there. If so zip it and attach it to your next post.
As I said, your PSU is not a very good one : it's overrated at 430W and its 5V line is too high (ATX specs say it can't go over 5.25 and as you can see it's very close to that). I would consider testing your computer with another good quality power supply to see if it solves the problem. You can borrow a friend's (try to find a 400W+ model and stick with good brands like Antec, Corsair, FSP or Seasonic) and see how it works before making unneeded expenses.
Use the
PSU calculator to know what wattage you're after :

Run
memtest to make sure bad voltages didn't damage your memory sticks. It'll take some time so start the test in the evening and leave it running overnight :

Leave memtest run overnight or at least do 3 full passes on your memory. It's advised that you test one memory stick at a time, removing the others from their slot. Report if it finds any error and double-check memtest's results with windiag as it runs different tests. |
