341983 2005-04-05 23:23:00 Hi all,
i've had abit of a search around on here and google but cant seem to find anything like my problem.

I'm trying to get a computer going but when i start it up the screen stays black, no beeps, no cursor, no bios,nothing and after about three seconds the screen turns off (power light for monitor turns orange).

Computer is a HP Brio 433mhz,
3.2gb hd,
64mb pc100mhz ram,
on board AGP graphics
with windows 98.

The only pci slot used is for onboard sound.

I tried another stick of 64mb ram(100mhz) from a working computer and no difference.
I tried a pci graphics card with and without cross over cable with no effect.
I hooked the box up to a working computer so i know the screen, cords are ok.
When i turn the computer on the hard drive starts and the fan goes but thats all.

Any ideas?
Cheers, Brian.

Umm when u say u hooked it up to a working computer, do u mean u connected the monitor that didnt go to the working computer? And it went?

Or did u connect the HP system to the working computer's monitor and it went?

If it has onboard sound, you wouldn't be using a PCI slot. So has it got a sound card in it? Then you need to disable the onboard as they will conflict.
What has a crossover cable got to do with graphics cards? A crossover card is a network cable.
You could have dead ram (it won't necessarily beep)
You could have a faulty power supply
You could have the CPU wrong, is it seated correctly? Heatsink on properly? FAn working? Motherboard has correct setting for that CPU, like the dip switches are reight, 133, 166 or whatever it should be on?
Once you have eliminated all those, then that leaves a faulty motherboard.

I meant i hooked the HP brio box up to a monitor,keyboard,etc thats from a working computer.

Sorry was meant to say, "the only pci slot used is for the network card"

The box was brought of trademe. Came with no hd,or ram. I've used a hd and ram from a working computer so can pretty much eliminate those two.
I can hear the fan and hd spinning so would that eliminate the power supply?
Anyway to test the mb, cpu or the graphics chip?

The 3.2gb hard drive i'm using in the HP brio is a spare that came out of a working system i have. I upgraded the 3.2gb hd to a 6gb hd. The 3.2gb hd has been laying around for a while. Would it of become corrupted?. I'll take the 6gb out of the working system and try that if you think it could be the prob?

That doesn't eliminate PSU - just means its not dead - could still be faulty though.
Cpu, well just check its in properly, the heatsink isn't on backwards or something silly, the CPU fan is dust free.
That leaves the MB and not really, you can't really test it exactly (well not unless you have tons pf spare bits that are compatible). But if you have eliminated everything else, it leaves....

TM, huh, can you get your money back?
I'd never buy 2nd hand hardware unless I could test it first.

341990 2005-04-06 03:28:00 I asked about hardware additions because in some instances if the power supply can't handle the voltage required for initial startup, it will shut down. In your case this doesn't seem to be the case. I doubt the harddrives corrupted, unless you had it lying round on the carpet or something Myth (110)
341991 2005-04-06 03:42:00 First check that the CPU is plugged in. The state of the data on the hard disk is irrelevant at the moment. You're not getting anywhere near that. You're not getting into the POST. But unplug the hard disk for the moment. While you are doing that check that the cable was connected "pin1 to pin 1". Some drives don't have keyed connectors; some motherboards don't have keyed IDE connectors; I've seen some cables with the keys wrong.:(

Is this one of the BTX systems where the power cable plugs into a board with the PCI slots, which the MB then plugs into ? If so, unplug and replug the motherboard.
