I have been tweaking my set up for the past few days no problem. I have saved alterations in the bios and booted into windows at least 10 times or so. Tonight I made an alteration to my ram divider and then the computer held at the tab, del option screen. I reset cmos using the easy reset at the back of the computer, selected my settings in the bios, and rebooted. Same again it held at the logo screen. Now when I reboot I am prompted to install a floppy and there is a bios checksum error message. I have tried resetting cmos x 2 and get the same problem. Now if I reset cmos and don't enter the bios it boots into windows. Any ideas folks please. Is my bios balked and does it need a reflash? I am using the shipped bios 11 at the moment.
 
you will need to clear the cmos by removing the battery and the mains from the psu for a good 5mins, while they are out flick the clear cmos switch on the back.

Go have a cup of tea and then come back and put the battery back in then the mains and make sure you flick the switch back to normal position. Click your heals three times say a hail mary and then power up the pc.

All being good should work :D
 
Couldn't get the battery out (don't laugh:D) Left the comp powered off for 5 mins, reset cmos , rebooted all seemed well, then I got a blue screen, and a prompt to install the Vista cd something about a corrupt kernel and repair? tried to boot into safe mode, no joy it just prompted for the repair. I reset the cmos again rebooted and didn't go into the bios and here I am back in windows. All this for a lousy 100Mhz on my ram lol. I'd got the Q6600 from 2.4 to 3.4 prime stable, my ram was 4,4,4,12 memtest86+ stable and this last push has brought hell to town:D What should I do?:)
To sumerise, go into bios= heartache, stay out of bios at pants default settings= windows,and forums.

Also for some reason I cannot restart from within windows. This worked no problems before hand. I can shut the computer down from within the OS but not restart it. Any attempt to change settings in the bios, gives me a checksum error and prompts for a floppy. Help! I need my max settings back lol.

Ok I got the battery out :) Left it for 5 mins, reset cmos, powered up same problem. I cannot restart from within windows, and I cannot boot into windows without resetting cmos, if I do go into the bios and try and restart I get the bios rom checksum error, detecting floppy drive A media. Clear cmos and reboot into windows. I am stuck in a loop and I wanna get out of it lol.How do I proceed now?
Thanks.
 
once in bios, halt on setting, put it to no errors, that should get yah going also before clearing cmos at back, try holding power switch for a wee bit.

mercyless, dont go anyhere I need help :) Is that the psu power switch or the power on switch. I think my windows is borked as I am getting the odd error at the moment. "halt on setting, Put it to no errors" where is that please m8? I am reluctant to repair or reinstall whilst I still have a life line to you guys. Could I reflash the bios, or leave the battery out for any longer. Sorry for the questions. Please let my bios not be dead jim lol.
 
Ok I've tried that, no joy. It just will not save anything I change in the bios. I even tried the hold the insert key whilst powering up as advised in the manual. The other thing that's concerning me is, that on post with my Vista dvd in the drive I am not prompted to boot from it? (This may be because boot from cd is not selected by default in the bios). If I need to reinstall or repair I can start that off from within windows, but I cannot reboot, only power down, reset cmos and power up again. Not sure what to do next? At least for now I can get on line :) Thanks for your help btw.
How long do you leave the cmos battery out for. Reading around, some say 2 hours, some say over night. I left it out for 5 mins, is it worth doing again ? Can this wipe a corrupt bios?

I cannot use my floppy, I have a usb key, and Abit flash from windows. Will flashing overwrite a bad bios? Also if I do it from within windows, I cannot reboot, only power off. If I do it from the usb stick, I will need guidance. Sorry to be a mare lol I have the latest bios downloaded, a bootable usb stick ( ah crap I cannot get my boot order changed, and usb isn't a default setting).
 
best not to flash through windows if system is unstable. i have'nt tried usb sticks for flashing as yet so cant help you there.

what psu you have btw
 
been some reports of corsairs psu's not working well with this mobo, with same symtoms you having, iirc seasonic / corsair are the same.

its one avenue you may need to try if all else fails.
 
PSU would be a last resort, obviously I can't rule it out, but it's been prime stable o'clocked the best part of 3 days. It will allow the cmos reset and the bios does go to defaults it just wont let me F10 anything. Do you have any links to the posts about the corsair psu problems?
Thanks again.
 
Hey thanks mercyless. It does indeed look very similar to my problem, infact this guy describes it better than I did, but it is exactly the problem I am getting:

Re: IP35 Pro CMOS Problem
Just to clear some things:

My problem:

Can't save any changes in the BIOS. Even if I just change the system date, save and exit, system tries to reboot, fails, then displays code "86".

To boot back, I need to clear cmos. When it boots at default settings, it displays "CMOS Checksum error". If I enter bios, make changes, the problem occurs. If I hit F1 to continue, it boots fine to Windows.

In Windows, anything I can change in Uguru gets save and reflects in the BIOS. That's why I can change the required 2.2V for my Crucial RAM, and managed to overclock my quad. Once I do the changes in Uguru, I can reboot normally. The CMOS checksum error is gone.

I ran memtest and checked RAM, no problems.
Hmmm looks like the psu. I suppose I can read up some more, see if there's anything else to try, and then make a decision. Thanks for all your help :)
 
Update. I just powered down, hit power button on case front to drain capacitors, switched easy cmos reset, removed the cmos battery, and noticed that I had fitted a 4 pin molex in the 8 pin socket on the motherboard. I also noticed that I do have an 8 pin molex connector. Fiddly as it is to work around the behemoth that is the Tuniq tower I connected the 8 pin. I also had the main power connector to the motherboard unplugged whilst I did this. Anyway, reconnected all cables, plugged in psu lead, reset easy cmos switch, powered on and booted up. Went into the bios, changed only a few things F10 and bingo, it booted into windows. Also a could restart from within windows aswell :) My stomach turned over when I noticed my cmos battery still on the desk:D Fitted that and back to square one. Checksum error on boot. I think progress is being made. Does this mean I will have to leave my battery out longer? Also does this mean the bios isn't corrupt because when I booted up without the battery it allowed me to save in the bios and boot into windows no problem.
 
clear CMOS, enter BIOS & select optimised defaults (set higher Vdimm if required), save & exit.
 
Seasonic 600w, It's been rock steady for a year on my old set up, I don't think it's that.

Hmmm now i had similar problems, but clearning the cmos and battery out resolved it, but then i also had a seasonic s12 psu, which i have since junked as the rig was unstable. Dont laugh but im now using a jeantech storm 700watter and all is fine.

I would still say though, that if the battery out and power off for a while does not resolve the issue you have a courrupt bios. As the others have said try flashing it, but not from within windows. i wouldnt do that on a good day never mind when my rig was playing up.
