BIOS trouble

[Goose]

My PC no longer boots, and no longer posts. According to zee manual, there are 4 lights which go out as the PC starts up, indicating the stage it is currently on.

On my PC, only 1 light is illuminated, which says something along the lines of 'Everything else OK, starting BIOS'. I've not been playing around with it, so I assume these things just happen? I've removed the battery for 8 hours with no luck, should I try for longer? Could the battery itself be dead?

*hopes the board isn't dead*

Pray it's the battery Dude & try another with everything crossed.

If you can lay your hands on a spare PSU, try that. Also, make sure all your cards, RAM etc are properly seated and the contacts are clean. Try a new battery as well.

[Goose]

I've reseated everything, I'll try a new battery in the next few days.

Some mobos have a jumper that you can either remove on add to reset the bios?

[Goose]

Good point, I forgot about that. I shall give it a go tonight as the battery was fine.

[Goose]

Reset it, no luck.

Just wish I knew whether it was the mobo or the PSU. Thankfully, I have a nasty presentation to work towards this week, a week of work in Malta followed by the biggest mistake of my live the week after. Should keep my mind of that bl**dy machine.

I'd offer if I could but I don't have a spare PSU either and knowing how fragile at least one of my PCs is I fear I'd break something if I started ripping a PSU out. :(

[Goose]

Right, back from Malta and have replaced both the motherboard and the PSU.

Same problem. The little 4 lights still get stuck on 'Starting BIOS'. CPU?

[Mark]

I assume you've unplugged as much as possible - HDDs, optical etc., removed all but one stick of RAM (and tried both sticks individually). If you have a spare graphics card, try that too.

[Goose]

Tried both sticks alone, no joy.

The GFX card is fine. When I got back from Malta I put the new motherboard in, and the machine booted perfectly. As soon as I turned it off, it has never been alive since.

On board there are 4 debug lights. Originally, the last one wouldn't go out. At the moment 3 are staying on, which I *think* is bad news for the CPU. I'm wondering whether my old PSU was fubbared, and swapping the motherboard before the PSU was a bad idea.

[Goose]

Fixed!

All it took was a new PSU, motherboard and CPU...

[MarcLister]

Quite a simple fix then. :D

What mobo, PSU and CPU have you got now then?

[Goose]

The motherboard is identical to the old one, a DFI Lanparty UT. I loved the old board, so hit ebay to find an identical one. The CPU is the same, an AMD Opteron Danishbacon (or something). The PSU is now an Enermax 700W jobbie.

I have a lot of porn to catch up on.
