Computer will not start after OC attempt

post #1 of 27
Thread Starter 
Howdy OCN,
Last night I was continuing my attempts to get this 1100t BE to stay stable at 4ghz. It almost did, too. My settings were as follows:
Multi: x20
RAM: 9 9 9 24
CPU voltage: 1.478

It ran through some benchmarking software fine, which it never had before. It then remained stable on all six cores in P95 for about an hour until. Highest temp it reached was 63 but it hovered around 58/59c.

Then, unfortunately, it stopped. The entire computer turned off and would not turn back on. The power button does nothing; it doesn't even attempt to boot. It's a pretty sorry situation.

What do you suppose I killed, and how? I know that 1.478 is just barely outside AMDs recommended voltage range but the temps weren't bad and I've seen people go higher. Is the motherboard fried? I don't even know where to start... My setup is as it appears in my disc. I've tried resetting the CMOS on the mobo to no avail. Any guess as to what happened would be much appreciated. I'm gonna go weep in a corner for a little bit...

Turn off PSU,then remove battery and switch the mobo on and off till the onboard lights go out,or the fan attempts to spin,leave it five minutes and put battery in and turn psu then computer on.
Chin up! everything is fixable,it just costs money sometimes

The thing is the temperature dieods on these are off by up to 13C, I always add 10 to my temps as a rule of thumb so I never go past 50 if I can help it....

I honestly don't see any good coming from those H50's either, I have an air setup at the sam voltage and I'm hitting 47-50...on air. You might want to add another fan or something with temps that high.

Ok... Turned off the psu, took out the battery... Held the power button on the mobo and the light flickered on and then went out, will not come on again. I follow you, now. ;D

Waiting a bit... Alas with everything back in place the onboard light comes on but nothing else moves.

Another MSI VRM failure I guess. Remove the 8 pins 12V plug and then push the power button.
If it start then it is the VRM.

You unplugged it from the wall too right? When you do so take out the battery and hold and press the power buttons. You want all the loads on the capacitors out.

Trying the discharge with the wall plug out as well... Still just the cold blue light of defeat.

Gonna try removing the 8 pin from the VRM next...
