LORD HELP ME *Fried CPU?!

[Homerboy]

I was just in my bios, tried upping the FSB jsut a few ticks from the 133 stock, dropped out and rebooted
Upon reboot, I get no video and beeping from my case speaker "dee-dee dee-dee" Over and over. "oh sh!t WTF just happened" So I reboot same thing.... same thing same thing.
Power off and walk away for a min or 2. Reoot and I get nothnig. PC seems to power on but no vid no post no nothing. I check the cute little "D-Bracket 2" which came with my MSI K7N2 mother board (v1.0) and has 2x2 LED display to help diagnose issues. Specically my LEDs are showing 2 red 2 green which translates to "System Power on: THe D-LED will hang here if the processor is damaged or not installed properly"
Ive tried CMOS clear, removed battery EVERYTHING

I tored reseating the CPU, the video card everything... SOMEBODY tell me Im not dead.

PLEASE.

AMD1600+, MSI K7N2 V1.0 as previously stated

How long did you keep battery out???

Try holding it out for awhile...Did you try the jumper to clear cmos??? Place it in the clear spot and actually boot it with it in the position....Then power down...


I doubt you fried the cpu since it did not boot from a mere fsb boost...The common thing s to clear cmos andyou are fine...however the board is older style so who knows....

Could have fried the cmos chip...

 

[Homerboy]

Tried clear CMOS repeatedly. I cant beleive that its fried either. Wish I had a spare XP laying around to try in there.
Battery was out for maybe like a min or 2
I tried booting with the jumper in the "clear" spot too... same thing.

Very bad idea.
This is very unhealthy to do to the motherboard.

oh, that's nforce2 gay board isn't it..

yep, it's the board.. your board is dead, that's why you're getting no boot. Nforce2 boards die if you overclock. Nforce2 boards die if you run it at default.. Nforce2 boards die if you underclock.. nforce2s are designed so they self-destruct any any length of time. That's the nature and you have to accept it.... 100 nforce2 boards will last you longer tho... and will cost you approx. 10,000 USD.

Yur cpu is fine.. they don't get dead easily.. as a matter of fact, they are very hard to be killed unless you take the sledge hammer and hammer the crap outta it..

get your manual out and lookup the location of the safemode jumper J10. I believe it is just above the agp slot a little back from the northbridge if i remember right move that jumper to the safemode position 2-3 and it will default the board to 100mhz bus so you can boot it up and get into the bios to undo what got you into trouble. the info can be found on page 2-31 of the latest manual revision. your board is not dead it is just unable to boot with the setting you gave it follow my directions and you should be able to boot it and undo what you did.

 

[MeowCat]

he already did the cmos clear old man..

once the board is dead, it's dead. cmos clear will no longer do any good.


nforce2 boards suppose to die... otherwise it wouldn't be normal..

 

[mechBgon]

Homerboy, you're clearing the CMOS with the system unplugged from the wall, right? You might try holding down the Insert key before and during power-up. Just keep holding it down for a while, and see if the system POSTs. Some boards take this as an override signal and revert to safe defaults... not sure if MSIs are like that, but it's simple to try Good luck!

 

[NesuD]

if you knew what you were talking about little kitty you would know i didn't say to clear the cmos. That board is equipped with a safemode jumper that locks the fsb to 100mhz in hardware specifically to allow recovery from the exact thing he did in the bios to wig it out. that board had 3 different jumpers on it 1 is for clearing the cmos and is located near the battery along the front edge of the board. there is another above the agp slot that you remove if you are using a 100mhfsb processor, and the third which is the one i am talking about is above the agp slot towards that rear edge of the board for forcing the board into safemode(2-3) which forces the board to 100mhz fsb regardless of what the bios is set at. the (1-2)default position on this jumper is for normal operation of 133mhz fsb on up. look at the manual if you don't believe me. I know what i am talking about this was the first nforce2 board i owned and believe me i did exactly what he did more than once in my overclocking adventures with it.

 

[NesuD]

Mech the insert key thing isn't how the K7N2 does that it used a safemode jumper on the board to force it to 100mhz default. It was one of the few Nforce 2 boards that included the safemode jumper from the original nvidia reference design.

Oh, gotcha You know what I really like about the AnandTech Forums, is that there are so many helpful people here.

:beer: Had that board for a while got to know the ins and outs on it pretty well.

Round 1

MeowCat vs NesuD

Faiight!

MeowCat stikes early with the NF2 Bash attack! NesuD fades with the blow and comes out of nowhere with the Newbie EyeToss! It connects!!!

FATALITY!!!

Back to the topic. I refuse to believe a few ticks could fry the CPU. I also highly doubt it killed the mobo. I'd follow Nesud's advice and if that doesn't work do what I always do. Let it sit for a while(30mins or so) and try again. Dunno why, but this fixes most of my computer related problems.

just boot with the 100fsb on/off?? and you'll be fine, had to do it with my msi k7n2 which is a great board

 

[cubanx]

It's not the CPU it's the MSI board. Same thing happend to me with a couple of MSI boards. Sometimes you can fix it with the methods NesuD described but the last time it happened to my K7N2-ISLR Delta no jumper tricks would resolve the issue and I had to RMA the board. Popped the CPU into a Abit NF7-S and it booted right up. I'll probaly just fleabay the rma replacement board they sent me.

I think this one has some life in it yet. usually the unrecoverable ones have the bios scrambled and are simply dead. Since it is beeping i would say it isn't scrambled just needs the settings straightened out. The board is quirky. You can't change to many bios settings at once or it craps. Basically make one change at a time and don't try going for the gold with it when overclocking just bump it up in short steps a little at a time until you find the limit. Still it was a pain in the ass board as far as i was concerned. Much happier with My Soltek SL-75FRN2-RL. Also if he was running that pc2100 ram in sync with the FSB then there is a good possibility that the ram doesn't like being overclocked as well. I know mine hated kingston ram.

Thats very dissappointing to hear about MSI. Although it is an entirely different chipset, my MSI KT800 board was DOA and had to be RMAd. I've never had any such experiences with the ASUS and Intel boards I had purchased before.

Odd Homerboy hasn't checked in.

 

[Homerboy]

And the winner is?!?!?!

Hot damn Im back in action.
Thanks to all that gave HELPFUL posts. MeowCat[b/] 33 posts in and your making enemies. Enjoy your stay.

Thanks again you guys. As always, anandtech owns liek no other. Saved me $$ of newegg.com... .then again Ill probably spend it ethere soon enough.

Godspeed.

 

[NesuD]

happy to be of help be sure to pass it on.

Agreed - i have same board, did same thing.
