Help. PC wont boot.

trydowave · May 28, 2013

My main pc just died. Well won't boot. The message I get is bad cmos. and another one that says dqs (i think) memory will now run at slower speed.
When i go into bios the date and time will no longer hold? I have 4 gigs ram, win7 64bit ultimate, 1 terabyte hdd, nvidia 9600gt. I will try to get more information if anyone needs it. hopefully thats anough to go on for now. ive tried different batterys to reset cmos. no luck.

Your CMOS battery died. There's a flat battery on your motherboard holding your bios settings, switch that for a new one.

On the CMOS battery replacement make sure the writing is facing up. There a plus and. - side to those batteries. If the CMOS chip went bad itself you can try and reflash it or see if replaceable and contact the mb vendor for a replacement or check online.

smorizio :

I tried puttingng in another battery... still nothing. first I get a message saying "DQS" training failed on previous boot, reverted to slo9postwer dram speed. then it says bad cmos. I go into bios and load defaut settings.. when I go to reboot it dosent even load bios post. I get a flashing cursor top left.
I have a ECS GeForce 7050m-mv 2.0 motherboard with a amd 64x2 6000+. ill try and locate the cmos reset switch or jumper today. if that fails ill look into replacing the cmos chip. I hope no soldering will be involved.

Cheers
Tony

Tony the black screen with blinking cursur is a hung mb. Try unplugging power to your hard drive and see if no boot device pops up.

Mostly all of the time a CMOS is soldered on, so i would be looking for a new mobo if i where you. Maybe time for an upgrade too? ^,^

aatje92 :

I only upgrade when I have no other choice (i'm writing this from an acer 270 travelmate that I found in the bin

)
I looked on my motherboard and found a rom chip. I beieve it to be the cmos chip and its not soldered. It looks like it could be pulled out (like the rom chip you'd find on an old amiga computer but smaller).
I also found a link to this site...
http://bios-repair.co.uk/Programmed-BIOS/ECS/Socket-AM2+ECS.html
my motherboard is is referenced at the middle bottom.
Can someone out there confirm if this is the correct chip to go for?
For now though ill proceed by taking the pc apart and booting without the hdds.
Cheers
Tony

idk i never changed a CMOS chip i always bought new board if it died

Sometimes, motherboards just die. I'd remove the HDD, get all the important data off with a Linux LiveCD onto an external HDD and buy a new motherboard. They are nice and cheap these days.

Ive got no problem with buying a new motherboard but i dont have the money currently to get all the other stuff to go with it. Appropriate ram, cpu etc.
I'll have to get the same motherboard or something similar.

amdfangirl · Jun 2, 2013

What socket is your current motherboard?

aatje92 · Jun 2, 2013

amdfangirl :

AM2+, he said it earlier

amdfangirl · Jun 2, 2013

I'm getting old.

Wouldn't be hard to find a direct replacement.

At least it's a new motherboard :/.

And he could slap a 965 in it for an upgrade too in the future.

trydowave · Jun 2, 2013

... i think i got it working now...
i resetted all the components including the bios rom. fiddly little blighter, i bent the legs on it and thought i had killed it for good.
After that i went to bios and loaded optimized defaults, got my boot order sorted and saved the time date etc. It saved this time and booted into windows.
Not sure if im out the woods yet but it looks promising

amdfangirl · Jun 2, 2013

Very nice. WOuld you like me to pick your own solution as the solution? xD

trydowave · Jun 3, 2013

amdfangirl: yes pls

Just thought I'd mention that the pcs been running fine for a while now. The gadgets sidebar crashed to start with but a few registry fixes sorted that out. Doing some more checks to make sure everything else is ok.

Thanks all for the responses.
