| 75160 | 2002-08-31 00:19:00 | OK heres the thing... I accidentally set the cpu voltage too low in the bios now my computer won't boot at all. The reason I was playing was that I've been having crashes on every cold boot I do, and I got this hunch that it might be the voltage to the cpu or something. So I cranked it up and it fixed it. Then I was turning it down a bit, and thought that the next step after the normal setting would be ok, instead of the highest setting of all. Turns out though that the next setting "after" normal is actually lower than normal, not higher. So anyway I need to reset the bios somehow without actually going into the bios, coz I can get there.... hence, I need a method of doing it via hardware. I located a couple of jumpers labelled "clr_cmos" on the motherboard, but I'm not sure of the exact steps involved in using them ... any suggestions? i've got a gigabyte ga-7dx+ motherboard. |

| 75161 | 2002-08-31 00:41:00 | or will taking th battery out for a while work? I should mention that there are not actually any jumpers on there. there are like little solder dot kind of things with no jumpers actually attached to it... |

| 75163 | 2002-08-31 02:34:00 | I've never done it and know diddlesquat about it but I understand you can 'flash' the bios to reset it. maybe ask about that. | mark c (247) | ||
| 75164 | 2002-08-31 02:54:00 | Normally, shorting the pins marked "Clr Cmos" would work, but if they don't put pins there, I'd be a bit cautious .It shouldn't do any harm ;-), and maybe they're just penny-pinching. What does the manual say? (Of course, you haven't got a manual). Removing the battery will clear the cmos settings, or most. I don't know if CPU voltage is classified as a "BIOS" setting --- it wasn't part of the settings for the 286. Remember, when removing the battery (a cell, actually ;-)) you have to remove the mains cord too ... ATX supplys keep some volts on the board even when turned "off", and this includes the CMOS backup supply. |

| 75165 | 2002-08-31 03:12:00 | Do a search for your M/B manual. This will tell you how to reset your the Bios. Every one is slighty different, but will not be too hard to find. Don't even think about re-flashing. Bye |

| 75166 | 2002-08-31 03:40:00 | I don't think loser could reflash it, Peter. The problem is that the CPU doesn't do anything, so it's in a fairly safe mode. :-( | Graham L (2) | ||
| 75167 | 2002-08-31 05:27:00 | You are so right. A quick look an the gigabyte site states that the Bios auto-detects CPU voltage - the manual is there in PDF format as well but didn't feel like doing a big D/L. Bye |

| 75168 | 2002-08-31 05:34:00 | yeah I don't really want to be shorting out random things when I don't really know what to do... I'm hoping that resetting the bios will work. Of course you would never have had to do it on a 286, coz they have all the jumpers and stuff physically on the board, but I believe that most new motherboards now use the jumperless design that was phased in during the early pentium days... (ok, someone correct me :D) I'll try the battery first. I did have a look in the motherboard manual but can't find anything explaining how to do it... (would i need to boot up while the pins are shorted etc? or do i just short them for a couple of seconds?) I'll have a look online for a manual anyway. Cheers everyone. Oh and Graham (I think) is right, I couldn't re flash the bios, unless there is some strange way to do it without booting up... ;) |

| 75169 | 2002-08-31 05:42:00 | Have you tried holding down the f8 or whatever key it is while booting? Bye |
