The front of the case broke off on an older system I built, and the parts have been sitting around for a few months. My friend offered me a case and I took it. I hooked all the front panel connectors to the motherboard but it wont turn on, even with 2 different power supplies (which i know work). I got frustrated and tried changing jumpers (not knowing exactly what i was doing).

The system was getting power but was not turned on...Until i lifted the clear cmos jumper off the normal setting, put it on the clear cmos and then took it off again. at that point the system turned on but with no lights or beeps. The only way to turn it off is by pressing the power swith on the power supply or ripping the cord out.

What could be wrong?

Any ideas?

Any ideas?

Welcome to G2G

Firstly, I want to just check something with you...
Are you saying you are moving the clear cmos jumper around whilst the power is connected? If so, then DON'T!

Can you give the basic specs please? i.e cpu/mobo/video etc

[Rhijaen]

yes i was =X

All it is is a motherboard and cpu..just trying to get it to turn on.

The mobo is a gigabyte ga-6vxc7-4x

The CPU is a celeron code sl46t (http://www.cpu-world...c/SL/SL46T.html)

OK. This is a P3 socket370 board, right?
What ram & video card are you using?

[Rhijaen]

Yes, thats right.

I'm not using either at the moment...do I need them in order to get it to turn on?

All it is is a motherboard and cpu..just trying to get it to turn on.

[Samm]

Er, yes a video card AND ram would help(!). The system won't post without them.

Also, check the dip switch settings for the cpu FSB & Multiplier :
FSB = SW1 = 1 : OFF, 2 : OFF, 3 : OFF, 4 : OFF, 5 : ON, 6 : ON (AUTO)
MULTIPLIER = SW2 = 1 : OFF, 2 : ON, 3 : OFF, 4: OFF

[Rhijaen]

Just tried all that, but still no response

[Samm]

Right, so you've tried powering up with only the cpu, agp card & memory installed, right?

Did you hear any beeps?
Did the cpu fan spin up?
If not, did the PSU fan spin up?

[Rhijaen]

Nothing happens...no beeps, no fans going, no sound at all...it doesnt turn on

Could it be that the front panel connectors are having problems? I got the case from a friend for $5

Yes, its possible

Please follow these instruction exactly

Disconnect the power
remove the video card & all ram modules
Locate the front panel header (should be in bottom right corner of board if you are looking at it the right way up)

You should see this :

..1 O O 2
..3 O O 4
..5 O O 6
..7 O O 8
..9 O O 10
11 O O 12
13 O O 14
........O 16
17 O O 18

Disconnect ALL the connectors from the front panel header block. Reconnect the speaker to pins 6, 8, 10, 12.
I can't tell from manual which pin is supposed to be positive, so try it with the red lead on pin 6 to start with.

Reconnect the power & power on the PSU (if there is a power switch on the rear of it)
Using a small flat bladed screwdriver, touch pins 11 + 13 on the front panel header at the same time (i.e bridge them together with the tip of the screwdriver). This should force the system to power up. As soon as you get power, remove the screwdriver. Be careful not to touch anything else.

If you get power but no beeps, power off again & switch the speaker connector round so that the red lead is on pin 12 & the black on pin 6. Then try to power it up again

Let me know if :
the PSU power up
the cpu fan powers up
you hear any beeps

[Rhijaen]

I did everything you said and it wouldnt turn on at first...

out of curiousity, i turned off the psu...switched the jumper to the clear cmos pins and powered it on, and touched the front panel connectors together, and it turns on, with a couple beeps

Connected ram and video card and keyboard...

I guess the power button works too, it just has to be on the clear cmos setting...

Everytime it boots it says "CMOS settings wrong" "CMOS/gpnv checksum bad". Press f1 to enter setup or f2 to restore defaults and continue. I hit f2 and it continued booting...it had no hard drives or anything in but im guessing it would work fine.

I'd rather have The bios settings correct and not cleared everytime i boot

I tried switching the battery with a known working one..didnt work..tried removing the battery for a couple mins and replacing it...didnt work

At least we're getting somewhere

OK, this makes me feel kinda stupid

I actually looked at the manual (for once in a lifetime) and found that the setting that I thought cleared it was actually the normal setting

The problem was because i had it on the clear cmos setting the entire time

Thanks Alot for all your help Samm

Funnily enough, after reading your last but one post, I was just about to check what position you had the jumper in!

Glad you've got it working
