When you get the new psu installed boot into bios and let the computer idle while watching the cpu temp if it still is at 62C we need to see if that is accurate because it could be another problem so using the scale below and after the computer is ideling in bios for 15 minutes see if you can determine if the temp is accurate.
Very carefully touch the base of the HSF,
40C to 45C = comfortably warm
45C to 55C = need to pull away after 5 seconds
55C to 65C = need to pull away after 2 seconds
70C = burnt fingers
If you determine the cpu temp to be above 55C please reveiw this install guide. I see the hsf came with a thermal pad so this eliminates the possibility of using to much paste but is is possible to mount a socket A hsf 180 degrees in the wrong direction. The steped portion of the hs must face the part of the cpu socket that says "socket 462"
If you find out the temps are normal say 40C to 50C then load the fail save defaults and install the OS and we can tweak the bios settings later.
Let me know what you find out

I touch the base of the hsf and I would say it is warm but I can touch it for more than 10 second without having any burning feeling.
I will do the test when I get the new psu which will be arrive on Friday.

Now clear the cmos with the jumper, you should not need to remove the battery.
Boot the computer to bios and load "optimized defaults"
Now check in "SoftMenu" and make sure the fsb is set to 166mhz if not set it to that
Now goto Advance chipset featurers>DRAM clock/Drive controll and press enter.
The ram clock will most likely be set to "by SPD" highlite it press enter and set a value of 166mhz.
You need to change the ram clock because you are running pc 3200 ram witch when set at "by SPD" the bios would auto set the timing to 200mhz, this sometimes can cause problems because it ain't running at the same speed as the cpu 333/166 mhz.
Now save and exit bios and load the OS you should be good to go
After you load the OS and the computer is stable you could try running the ram clock at 200 and see if the computer remains stable mine does but if you have problems set it back to 166.

cfqta, would it be possible for you to post the context of the bluescreen, not just the line you posted? I can help a bit more from there as far as diagnosing the problem further.

The bluescreen error you're getting is definetly a hardware related error.... And Doby, mind if I join in in helping? Not trying to hijack a thread you're helping in though.
No problem, in fact I encourage extra help/ideas as long as its productive.

But when I try to do a fresh installation of Windows xp, I can only get to the point right before it asks you to choose which hard drive to install the window to and I will get a blue screen with error "Driver_IRQL_NOT_LESS_OR_EQUAL" error. Do you know if it will cause by CPU and RAM running at different speed?
I doubt it but lower the ram clack to 166 mhz for max stability and follow my other instructions to the letter and post back the results.
In bios under "SoftMenu Setup" what is the DDR voltage? It should be 2.65 if it is not set it to that and run memtest again and post back the results.
If the computer fails test #7 again then set the DDR voltage to 2.7 and run memtest again.
Now that you have the reboots fixed by replacing the psu I am trying to determine why the OS won't load it seams to be ram related but not bad ram. Its a well known issue with some boards failing test 7 I did not know the KV7 to be one of them. The makers of memtest recommend uping the voltage to the ram and this sometimes helps and I am thinking that the bios is not setting the voltage correctly thats why the OS won't load and the #7 test failure.

I also change to force DDR to run at 166MHz, and run the memtest again. However, it still fails the test#7. Then I try change the voltage to 2.7, but it didn't help.
And then I change the voltage back to 2.65 and try a fresh install of Windows xp. and I got a blue screen. Please click here to see the detail info of the blue screen.
