A common issue with a difference

[dr4g0nf1y]

I was playing around with the overclock settings in bios for all the major commonents early this morning and now my pc won't do anything.

 

It's plugged in and when I turn it on all the fans start, leds light up and then it cuts out. I was toying with the idea that my 550watt psu is too weak to cope so it just shuts down.

 

I disconnected all non essential parts with no success. I reroved the 4 pin eatx 12v connector and for some reason the pc starts up and stays on. Nothing loads from the harddrive and nothing appears on the vdu. Both of the standby and restart buttons (board and case) work to turn on but not off.

 

All the leds on the board are showing crazy mode.

 

 

Best thing to do is to turn the bios back to the original settings.

 

Saying this I've turned the clr cmos switch on and off, held the I/O on the back during startup holding delete, unplugged and discharged and also removed the battery for 30 or so minutes.

 

I now some boards require longer so I'm leaving it overnight with the plug out too.

 

I think it should be fine if I can wipe the bios memory and seems like the only way that it will happen is if I bleed it dry.

 

 

Anyway, it's a little old but here's the specs:

 

intel e8500

Rampage Formula (Republic Gamers Edition)

4x 2gb OCZ 800mhz

2x 1gb ati radeon hd4850's

and a colorsit 550 watt psu

 

Any ideas?

 

Thanks :)

Hello and Welcome to Extreme Tech Support - Free PC Help

Enjoy the forums :)

 

Try another PSU first and see what happens. Tell us what the outcome is ;)

when the board powers on are you getting any bios beeping at all. if so what sounds.

it gives out a code basically,,,check your manual and it should give you a description of the beeps...

post back

no beebs.

 

I left it over night, so would have had to have been a good 12 hours, same problems.

 

The board still states crazy, so some how the bios has remembered what I set it up to, which in all fairness it shouldn't, not without the battery.

 

 

Things like this with the led poster displaying cpu init which I think I forgot to mention in my last post (it was late) always mostly seem to end in the same way, with an rma.

 

It's very strange, is it the motherboard, or the cpu.

 

The computer starts up with no beebs without the 4 pin from the powersupply connected to the board, but when it's plugged in power gets everywhere then shuts down after a second.

 

The 4/8 pin gives power directly to the cpu... so why does it work without and not with.

 

 

Obviously the fact that it's working and not beebing means the cpu is still actively working, so I don't know :(

[danzil]

the 4 pin needs to be connected,,,, this is part of powering your board fully.

can you obtain a spare CPU to check with....or a try your cpu in another board

I've read elsewhere... well saw on youtube someone with the same issue, but he had no lights for his cpu status, if that means the cpu is screwed so be it but I'm still going to have the motherboard set to those higher settings.

 

The battery has been out for 24 hours, going to leave it for another just to see if it fully discharges.

 

My other pc is AMD/Geforce bases so I can't swap anything over :(

[danzil]

that should of discharged ages ago i expect that it has, but the CPU is causing the problem,,, if it is dead can you borrow or obtain another cpu and pop that in and see if it post's

You don't need to leave your PC battery out any longer than a few seconds - as long as your mains lead is disconnected.

 

It will have reset by now.

 

Disconnect all drives, all USB devices, leave it so you have mainboard, PSU, video, keyboard and mouse connected only.

 

Remove 1 stick of memory, power it up, no good, try it with the other stick.

 

When you were overclocking did you increase the CPU core voltage, or leave it on Auto?

 

Did you keep an eye on the CPU temp?

 

If the volts was left as Auto I'd go with a board failure rather than CPU, but unfortunately it could be either.

[dr4g0nf1y]

I can order a new cpu for £40 so I could get another but because this was my first intel I don't have any spares.

 

If it has discharged and the cpu is causing the problem, why would you say the board is still on crazy mode?

 

I overclocked:

 

The north Bridge

Memory

CPU PLL

CPU VTT

 

 

Once I saved these in bios the computer restarted then turned itself off after 2 seconds. Now everytime I turn it on that happens, unless the atx 12v isn't connected then everything runs but not posts.

 

I had no chance to measure the cpu temp lol

 

I'm now using my amd based pc although I'm on my mac now, but the other is so out of date, doesn't even have xp sp3 :p

 

 

I'm going to leave it until the weekend before I have a look at it but unless those motherboard settings haven't gone down, I won't risk putting anything else in it.
