Try replacing the battery. A lot of machines have problems booting if it's dead.

Look at this to see what is stored in PRAM. Not replacing the PRAM battery in desktops, and not keeping the backup battery in portables charged, is inconvenient at least and terminal at most, and a false economy of effort and money.

Ok, I left ONLEY the MB and PSU and Battery, and the battery is charging. When I first checked it it was 0 volts. Now it is 1.0 volts!
I will post if anything comes up.
P.S
i noticed how easy the IIvx is to take apart! Wow! only 4 screws! ;D

PRAM batteries are not chargeable... trying to do so will probably just make it explode [xx(] ]'>

Oh, so the motherboard does not charge it? Well why did they use lithium? :?:

Nope, the motherboard does not charge it at all. The reason they used lithium is because of the long life offered by lithium batteries.

There are primary, one use non-rechargeable, and secondary rechargeable batteries. There are lithium cells in both categories. Despite the appearance of USD0.01 primary lithium half-AA 3.6-V cells in eBay sales, there is more reason to applaud the recycling intention behind them than the utility of the batteries. New lithium primary cells are cheap-as-chips (about USD4) from eBay sellers such as ronaldo101, and have a life of 3-7 years, depending as the Mac is always powered from the mains or not.

I had a IIvi and it was quite a stinker. You may be able to rig something up, I know for my Quadra 840av I put two double aa's in bracket and attached it to the terminals and it worked.

The IIvx isn't one of Apple's better moments in computing history. I swapped in a Q700 motherboard into mine, but a Q650 board would be a better choice if you can find one. The IIvx is just snail slow compared to a Quadra. I'd upgrade that sucker as soon as you can.

About 6 years ago I swapped out my IIvi board for a Quadra 650 motherboard. It was a lot better, you could run OS8 and use 72 pin ram.
