Hello everyone, I did something without using my brain. I was in my bios screwing around with the settings, I set my fsb as 166mhz and then I saw the memory frequency and then I changed it to 200mhz, stupid stupid now I can't boot up, when I turn on the computer nothing happens it just sits there on, nothing on the screen, no beeps. So I'm thinking the solution to this problem is reseting the cmos right? How do I reset the cmos in a ASUS A7N8X-E Deluxe? :helpsmile:

Look on your motherboard right beside the battery. There are jumpers marked: CLRTC1

See page 37 here: http://www.asus.com/pub/ASUS/mb/socka/nfor...8x-e_deluxe.pdf (http://www.asus.com/pub/ASUS/mb/socka/nforce2/a7n8x-e/e1322_a7n8x-e_deluxe.pdf)

Probably too late now, but with that mobo you DO NOT need to clear cmos to boot after you've screwed the timings.

There's another jumper CPU_FSB to the left of the Northbridge chip (and below the cpu). Normal position (pins 1&2) allows bios controlled FSB (266/333/400 MHz). Alternatively pins 2&3 forces FSB speed to 200MHz (100MHz base frequency). Although this is intended for Duron processors, it gives a setting which allows you back into the bios without losing all your other settings.

That's a nice little feature.

Yeah. There are some motherboards that will undo a too high clock setting if you hold down a key on your keyboard while you power on.

Funnily enough I thought I'd seen Asus boards with that feature instead. Prolly on the few A7N8X-X I've installed.

My problem was the ram not the cpu bus

It sets base speed to 100MHz not 133MHz or above, so it affects ram timing too.

and prying the battery out was hard too

You shouldn't have to pry out the battery.
It is retained with a little spring clip...pushing in the clip pops the battery right out.

Well you could try what I did the other day. I dropped a metal screw in the case. If you can believe it ,while putting the case on it's side to retrive the bloody thing . I reset the cmos . :lol: Scared the hell out of me, on a reboot. I swear I pulled the power cord too.


Edit : Was installing a PCI card .

the screw touched something and made it reset? :blink:

how lucky is that lol.

i've had screws, heatsync, all sorts of stuff fall on my video card WHILE IT WAS RUNNING and nothing happened any of the times. :01:

Yep, Hmmm default settings or optimal settings ? Oh what the hell it&#39;s a p2 266 mmx a friends child&#39;s puter . So I hold my breath and cross my fingers, go for the optimal ever time &#33; ;)
