Super weird error. I have no idea. Help

[Hans Voralberg]

K it started this morning. i turned the comp on. Everything goes on, lights up, fan spin. EXCEPT there's no POST. Look at the debug leds, it said no CPU detected, WTF. So i clear CMOS no help. After being left on for bout 2 min it POST, CMOS reverted to default settings. Everything went normal again. So i turn it off and go to school. But this afternoon the damn thing happen again :|. What's wrong ??

I checked there's no shorting/no malfunction hardware/no misplaced component, nothing

[dodgybob]

Two things I can think of:

I had a similar situation ages ago with an nforce 2 board where for some strange reason it was cured by reseating the cpu even though it was properly seated and had been for a while.

The second thing is perhaps the cmos battery is dying and causing weird effects. Have you got a spare from an old system you could try?

[Hans Voralberg]

Im thinking in the direction of the battery, dont have one atm but it's doesnt seems right, i just bought the mobo last week o_0

[Dav0s]

u overclocekd too much....bub bye opty

no seriously..u killed that beautiful cpu

[peterb]

Try reseating the CPU...

[madkez]

i was gonna say.....sounds like the cpu is on its way out makes one wonder whether its worth it going for the overclock

[Hans Voralberg]

LOL. K i reseted the CPU and change the battery. It takes ~1 min to Post now, otherwise it's running fine. Damn i dont wanna to spend on another CPU now, but overclocking is an addict lol. BUT SERIOUSLY GUYS, IS IT DYING ???

[Hans Voralberg]

Now after a while it's working normal, well sort of. Now it randomly shut down. And not the Windows routine shut down, it shut down like there's a power loss or something like that. But my comp is surge protected ??? And there's no electricity problem ??

i doubt its dying, most probably the mobo is fubar'ed as its the only thing that could have an effect on all of them things.

I presume its flashed to the latest bios? (although i have no idea what it fixes)

[Hans Voralberg]

Yeah it's running the latest one. Although i got no idea how a mobo could get fried overnight while the machine was turned off ??

[Frostbyte]

Hans,
It sounds as though you are fairly computer savvy, so without offending......... It does sound like it's motherboard related. Try reinstalling the most current BIOS and chipset driver's for it. Do pay attention to make sure BIOS is compatible with the current driver's. I forgot to do this with my A8N-SLI during an update and got all kinds of similar probs. I got the updated drivers and all has been well for months.

[[DW]Cougho]

Well if its gonna break it will be the initial surge of power from the PSU which kills it id say. Although it may not be the motherboard, it certainly is a strange problem.

One thing i do doubt is that you have killed the CPU, it *may* have been damaged from the start but i doubt you have killed a perfectly healthy CPU, but id still say its the mobo at fault.

[Hans Voralberg]

Damn im dont have time to dissemble the whole machine to test just the mobo. And thx for the help guys. BTW, i re update the latest bios and chipset driver etc. Currently testing it with S&M

[tungst3n]

What PSU have u got?

It could quite easily be a failing CPU.

That could after Post and cause random reboots. Have u got any other PSU's to test?

[Hans Voralberg]

Running the Akasa PowerPlus 650W. I chucked a multimeter in already, all lines are stable. This is a server class PSU so i doubt it's the source of problem. Any how the system is running under constant load for 1 hour now. Nothing yet.

[Hans Voralberg]

Oh well. Don't have to worry bout the problem now. The mobo just gor fried, literally. The chipset got a nice black mark on it. God know what's wrong with it. I got no idea watsoever. The PSU doesnt smell burned, or looks boomed but guess ill have to check.
