Soyo board resets during installs

Soyo / 7VEM

Specs: Ubuntu 8.10, 866/512
Well I was tinkering around with a old P3 board going to see how well Ubuntu ran on it when I ran into a strange problem.

I put in the disk, started it up and proceeded to install. It would read the disc, select English, check install and the computer would just restart.

Thought it was weird so I tried a damn small disk. Similar problem. It would boot then lock up and said something along the line of bios messed up.

Very odd as last time I used this pc it worked fine. So I cleared bios with jumper, checked bios battery, and tried again.

Same results. Next I figured i'd swap drives so I got another good dvd rom, then hard drive, followed by power supply.

Each time same errors.

Finally I decided to flash the bios. I booted up the computer with a boot disk, ran the awdflash, backed up old bios and installed the new updated one.

Same issues as before in Ubuntu and DSL pretty much the same but gets a bit farther before the random reset.

Tried swapping ram, cables, and again power supply.

No bios error with dsl anymore but nothing will install it just reset's itself.

The motherboard is s Soyo SY-7VEM

Any ideas as what would cause this anyone?

Thanks Chad.

Did you ever enter the BIOS screens to see what, if anything was amiss? You must enter the BIOS after a flash to reset the values as needed.

Yea I re entered my settings in the bios. Had to reset boot order, set date & time, disable floppy drive since I only used it for doing a bios update. It still recognizes my dvd drive & hard drive.

I'm not sure if it would be a improper bios setting or bad bios.

All I can say is I don't get linux's bios error anymore but still have the same reset issue.

You've covered most of the bases. A couple of thing I could recommend would be to reseat ALL cables, cards, RAM. Try entering the BIOS screens immediately when booting and monitor temps, if that is an option in that BIOS. Also, checj for bad capacitors. Look for leaking or bulging tops. Make sure HS fan is turning too.

Well I swapped everything possible and changed the 866 P3 to a celeron 700 and i'm running on ubuntu 8.10 live as I type.

I still have a few glitches as it took a couple tries to get to this point but I think you may be on to something with the capacitors.

There are two of them next to the cpu that look ever so slightly swollen compared to the rest. Which also compares to my voltage issue. It took 3 power supplies before I could get this to boot live. Plus I couldn't add a hard drive.


From what I conclude it must require a lot more power to make up for the swollen capacitors. I too notice there is a very high pitch noise from each power supply kind of line Morse code lol. This noise was not noticed by other computers so it must too be cap related.

I shall be looking for some caps now. 10v @ 1000 uF shouldn't be too hard to find. Time to break out the ol solder sucker.


One funny thing is I have a old Asus A7V8X which has very similar issues that I was troubleshooting about a year ago or so.

It too worked when I downgraded the cpu and put in a new 430W thermaltake power supply but sadly I could never figure out it's issue. I got it out of the box today and checked the capacitors but none show any sign of being swollen or leakage. So it's one for the soyo and athlon get's shot down again.

Thanks for the cap tip, if I ever get any caps i'll let you know how it turns out.

There was a period of time a while back when a good portion of all the capacitors used on motherboards were made using bad electrolyte. This of course made them go bad. There were class action lawsuits for at least on brand (Abit) and many others had the same problem. I personally replaced three boards with bad caps. None of the boards I replaced had leaking caps. All had bulging at the top where the cap is segmented. Had one board that you could move the capacitors up and down but the solder was intact. The leads were evidently loose or something.

The symtoms were the same. At first the computer generated errors. I think at that point the board caused data corruption. then it would take multiple tries to boot. Eventually they wouldn't boot at all. Below is a link showing typical bad caps.
