Little help

[bizzare6543]

My E2140 has been running at 2.8ghz stably for about two weeks, then I boot it up today and its gone back to default. If i try to up the fsb again and restart it just loops "no signal" on the monitor and constant staccato beeps.
Any help?

I've not cleared the CMOS yet, but thats obviously an option.

It is constant beeping btw.

And also, It works fine at stock, but as soon as i increase the fsb it just doesnt boot and does the constant staccato beeps ;(

Everything is new btw (rma'd my previous gfx card and got the 7900 )

Also this was very sudden, last night it was working fine at 2.8 and now i cant get it past stock. Any ideas?

Loaded Fail-safe defaults in my bios and now I've booted at 2.8 So im running a stress test and ill say how she goes.

0 PCI cards in at the moment. But its all running fine now, but it was a bit of a weird problem to begin with.

Hmm, my mum booted it up this morning, apparently it was blank, had to restart and tis booted at stock again

What the hell could this be?

Just loaded the fail-safe defaults in the bios, and it boots straight back up at 2.8 what i had it at stable for 2 weeks

This is very strange
