"System Failed CPU Test" ---> The SOLUTION

[The Pentium Guy]

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARGH!

That problem propped up at a LanParty once, and my system woudln't boot (ASUS P4P800-e Deluxe).
It happened to me twice before. Now it happened agian. Alright, after reading about this problem for over 4 hours, I figured out the solution.

When does this problem happen?
-When you shut off your system without shutting it down
-When your CPU overheats and it shuts itself off
-When you overclock and the computer shuts itself off (See above)

What others do to fix this problem
-If you read around some forums, people will say that they couldn't boot with their ASUS so they return it and get a different board (ex: Abit or something).
-Some people say replacing their PSU works/
-For some odd reason, by all this the VIDEO CARD is affected. Everytone with this problem seems to relate this to their video card.
-Everyone that tried to clear their CMOS says that clearing the CMOS won't work

My Hypothesis
-I think it's a video card conncetion problem. When you swap your motherboard with something else, the video card is obviously reseated onto the new motherboard and it "surprisingly" works
-When you get a new PSU, you connect the molex connector to the video card, and people claim that it works

Solution
Here's what I beleive to be the fix for most(aka NOTall of these problems:
-Be sure all your connections are firmly tucked in, and that your CPU isn't overheating.
-Disconnect the Molex connector from your graphics card, and reseat the graphics card, and put in the connecotr again
-If that doesn't work: then use a different molex connector

I really don't know why this is a "System failed CPU Test" problem, but what I did (see "Solution") made it work for me. I did the same thing at the LanParty, it worked too.
All I did was simply reconnect the 4-pin molex connector and that fixed the problem for me.

I hope this helps the people wth an ASUS P4P800-e Deluxe/ASUS P4C800-e Deluxe/ASUS A8V Deluxe (I see this problem on those boards typically).

I have a feeling that this issue has been resolved on the new ASUS boards (A8N-E/A8V-E/A8N-SLi).

Thanks for posting this.

I've just had the same problem with my brother-in-law's P4C800-E. We figured the CPU gave up since we had been OCing it and then is just stopped after stress testing. He was ready to upgrade anyway, so he used it as an excuse. But you've given me some hope that we missed something. I guess we will give it another run.

:thumbsup:

you are a prince among men.

thank heavens i was desperate enough to give such a far-fetched solution a try..it worked! i signed up to these forums just to thank you for this post. i'd been reading through pages and pages of this crap for months, bitchin' betty was driving me nuts for ages with the system failed cpu test! system failed cpu test! system failed cpu test! system failed cpu test! ARGH. props to asus for the most annoying and misleading error message ever.

ggeeeee thanks for this post, now i have an idea... i just got an ASUS P4P800-E Deluxe for 3 days now (very cheap - 5mos. old 2nd hand with complete stuff of the box still)... so far i'm doing fine, setup was pretty straight but except for the on-board audio, though haven't really tweaked it out yet coz i'm quite busy at work as of the moment... but anyways, i hope i won't be able to encounter this problem though...

and oh, now i have an idea of why my friend gave up on this mobo................

TY!!! It WAS my Video Card! The set screw holding my Video Card in made the Card skew a hair. Removed the set screw, reseated Card andunplugged and plugged the power for it. Working 100% now. Funny the message was CPU FAILED???!!! TY again for your post and WORKING FIX!!!
