No post w/ 680i LT, e8400 cpu's fault or something? plz help!

[aNoN_]

Hello, i installed my new parts yesterday and everything seemed fine. Until i tried to start the computer. All fans were working, the graphic card was working, the harddrives were spinning fine, all cables seemed to be in place. But no post screen, nothing its just black. Its like the computer starts but there is no signal to the monitor or something. I also have no power to the keyboard and mouse it seem, they are both connected to the USB ports on the back of the case but they are dead.

Can this have anyting to do with my Intel C2D E8400 woldfale CPU? I heard you have to update bios unill the new intel cpu's will work, is that true? I dont know what to do here, so i am asking.

[the_dope_chaud]

you probabbly have an old bios on your motherboard, one that dosent support your processor.
your best bet is to find an old socket 775 cpu to boot and install latest bios.

[aNoN_]

So you are basically telling me to get one of the older s775 intel CPU's like the e6600 or the e6750? to update the bios with? That sounds totally retarded, i cant just borrow one in the shop like that. And buying a CPU just for that purpose doesn't seem sane at all. What shall i do?

How did you others do with the 680i LT and the new wolfdale?

[Miker]

I though to 680i LT doesn't support 1333FSB, only the 680i does?

Right on the money I think.

You'd have to update your BIOS to P07, if you don't have a CPU that will allow you to boot, then I'd suggest go to the shop where you bought the mobo and ask them to update your BIOS for you...they should be able to help you out there...

Search for MB-N680-ILT9, then down the bottom, check the notes for XFX BIOS Update BIN File

You shouldn't need to update your BIOS to be able to boot with the Wolfdale CPU. Worst case scenario is you boot but the CPU info is displayed wrong so that doesn't sound like the issue (so I have been told, haven't tried myself). New builds are tough to troubleshoot to say the least. Have you tried some of the components in another system to ensure they are working correctly?

[aNoN_]

No i havn't tried them elsewere... If i upgrade the bios will i be able to boot then? Because for now i cant even get to post screen, the USB ports seem to be dead too. Altho i am not 100% sure i connected all stuff and cables the right way since its the first time i am building a computer from scratch. So i am getting it to a service guy i know who is really good. Hope for that, if it doesn't work after that then am gonna try to update bios.

Thanks for the help all...

Well I had the same problem and I updated the BIOS, it boots after that. The only problem is on the BIOS screen CPU info si dispalyed wrong even with the update. Yhe only problem is you don't get any video. While you load windows XP it becomes black. Anyone one got idea about what's going on?

[samr350Z]

Its your motherboard buddy... i went through same problem... alot of these 680i LT are bad...just read the reviews on tigerdirect... i got myself a EVGA nForce 680i ...works! same memory...same CPU..some power supply.

[aNoN_]

Na u gotta be frigging kidding me. U mean its the damn motherboard? What shall i then do? Return it and beg for another one?

Thing is, this motherboard had everything i wanted. Supported intel c2d, 1333mhz it supported SLI and it was a good overclocker. I read several reviews on this card and they all said it was a very good card. Besides it had also a really good price. I cant believe this would be a bad card. It MUST be working on my system. Shall i mail XFX and ask them? Or can i get an answer what to do here?

Oh, lemme try to update bios. More exactly how do i do that? First i need an older s775 cpu like the e6600. Shall i talk with the place i bought my motherboard from and tell them to update bios for me? This is a damn problem and any help is appreciated...

I have the same issue with my xfx 680i lt board with an e6750 processor. It worked for 1 1/2 months, but it just stopped working yesterday. It loads the initial "XFX" screen, then just sits for a long time. After a while, it reboots stating that I should reboot the CMOS or change memory timings. Everything is set to default. I've already tried pulling the CMOS battery out and putting it back in, but it still will not make it past that screen.

Now my new computer is a $700 paper-weight. Please help! :frown:

[srpeters18]

No, it is not necessarily your mobo, it may be, but not a certainty. People overreact when they read some tech support forums on the internet and assume that means most of them are bad. You just don't get positive reviews.

I actually had the same problem with my 680i LT after I upgraded my PSU. Reset the CMOS jumper, pull the CMOS battery, let it sit for a couple hours or even overnight. That's what worked for me.

[samr350Z]

Im not over reacting...this forum alone has a few threads about the xfx 680i, similar setups...but they all do the same thing!... no signal to monitor, no post...and NO straight answer to the source of the problem.. i went through TWO xfx 680i's...same crap...i paid a few extra dollars for the EVGA nForce 680i ...which i think its about the same thing except for the 3rd PCIe port....and im HAPPY! no sweat on post or anything.

[samr350Z]

oh yeah return it! tiger direct was pretty good in understanding the problem...now you got two options...

1) RETURN IT!... and wait.. till they received it and ship you another one, which takes about 2 freaking weeks.

OR

2) Buy the mobo AGAIN..and return your bad mobo and wait about a week..then a few more days to get your credit back to your creditcard.

[srpeters18]

You paid a few dollars more for a 680i instead of a 680i LT. That's the difference. But because you see a few threads here and a few over there doesn't mean there is an especially high percentage of them. There are just a LOT of 680i boards out there. Anyway, like I said, pulling the CMOS battery out for a few hours solved the problem for me. Same with the 780i. Ran into a problem where it wouldn't complete the POST, even tried resetting CMOS. After a couple hours of no battery though, it booted just fine.

[samr350Z]

I know what you mean..but why take chances ... :icon_tiphat:

[aNoN_]

I wont return it if i am not 100% sure its broken. I wanna try what i can first. I tried to move the jumper back and forth one time and pulled out the battery for 10 minutes but it didn't help. Maybe i shall try to leave the battery out over the whole night?

Is the CMOS jumper important or can i just remove the battery? When i move the jumper to the left, then back again is that the right way to go?

Finally i wanted to add that i only have a 4-pin power cable connected to the 8-pin ATX_12V power connector located at the top left corner of the motherboard. Do i HAVE to have a 8-pin connected to it for it to work? Because my Hiper PSU aint got this 8-pin cable so what can i do? Can i buy a different cable or a converter for it or do i have to buy a totally new PSU?

Thanks for the help all, however i would be glad of someone from XFX had something to say about this!

[srpeters18]

Well, the 8 pin is for the CPU power. I ran a Q6600 on the same board with the 4 pin with no problems, but the e8400 may be different, I don't know. As far as I know you can't get an adapter of any sort for that, you would have to get a new PSU.

Well good luck buddy....

Well good luck buddy....

That didn't help me much... :|

[Ursul]

I had the same issues as you. Only that i have the q6600. Changed the PSU and it worked for 2 weeks, now it won't POST again, nothing changed in my system....it was great while it worked.

[aNoN_]

Ok i solved the problem. It was as easy as i thought. I just updated bios to the latest version using one of the older conroe core 2 duo cpu's and it worked with my penryn, wolfdale :wink:

However, in the strugle of changing the cpu to use for flashing the mobo i accidentically fried my PSU with some nasty static electrisity :frown:

But its Hiper so its 3 years warranty, and mine is just under 2.5 year old so i hope i can get a new one for free.

Never touch anything inside your PC with out moving it to a table, in a room, with no carpet.

[srpeters18]

Never touch anything inside your PC with out moving it to a table, in a room, with no carpet.

Some of us don't have rooms without carpet. Just be smart and touch your case chassis every time you get ready to touch something else. OR even better, get one of those anti-static wriststraps.

[Miker]

Anti-static anything won't help if you are working on carpet.

Now my new computer is a $700 paper-weight. Please help! :frown:

I posted this a couple days ago, and I decided to give my computer another try. No change. Then, I decided to unplug the USB ports for my printer & ipod. It freaking worked!

Now, I tried to re-plug in my USB printer and ipod, but the USB ports they were in were bad (can't recognize anything plugged into them). It seems that my POST problems were due to bad USB ports. Maybe it was trying to find bootable media??

So, my computer isn't a $700 paperweight, but I have 2 bad onboard USB ports. I'll still need to send it in, but at least I know it works (sort of)! :lol:
