My PC is being naughty!

Hi All,

I'm having an issue with my PC which has me stumped, any comments appreciated.

4/5 restarts will not beep and it hangs on the black screen before anything happens with the bios, machine is on/fans noise etc.

2/5 regular boot ups are the same problem.

If I make any change to ram timings etc it will often one long two short beeps.

Otherwise, it's fine - better than ever in fact! All was fine with it and then one day without making any changes the above happened.

Any ideas.

It's a;

Asus A8n premium
3700 AMD, (no over clock)
Ballistix pc4000, (default timings 1.6v)
GT7800 BFG pre o/c
Seasonic 600w
network card

latest nvidea driver, asus website nforce 4 driver

Erm are you sure that your memory is running at 1.6v? As it should be more like 2.6.

Yes your right it's at 2.6v. The stock voltage on the crucial website is 2.8v but it wont run on that.

First reset your bios to default values, check thats not the culprit. Then download memtest and boot it from floppy, run the tests and check that your RAM isn't at fault. After that it starts to get a bit vague.

Thanks Dureth I have already reset the CMOS and run memtest for 2 hours with no fault. I'm totally there with the bit vague feeling!

Ok I am officially stumped! If I think of anything else I'll post again.

The only other thing is test your components 1 by 1 in a friends machine if possible.
