Okay so following advice I reset the BIOS.

Anyway the computer started up okay afterwards, but I haven't switched it off since so I don't know if it fixed it or not.

Anyway after the screen which shows press so and so to enter BIOS, it came up with 'CMOS Bad checksum', and 'Time and Date incorrect'.

So I press F2 to load up default settings, and and so far everything's fine, but I wn't know till I turn my pc on and then back on.

So is this CMOS thing something I should be worried about?

Problem still persists, it's really getting on my nerve now.

You might want to take out the CMOS battery, for an hour or so just to make sure it's cleared properly. Twiddle your thumbs then put the battery back in. this should clear it to its defualt.

Make sure all your aower connectors are attached properly. My new seasonic plug's catch clippy thing does not attach to my new ASUS motherboards power connector very well. It didnt seat properly for me the first time and I had a heart attack when the Mb lights turned on but nothing else. (I then had more problems that I wont bore you with)

You should only be worried if the time is never set properly

Tried taking the battery out but it looked pretty impossible unless I pryed it out with force, any particular technique to these things?

wang a screwdriver in and yank

unless theres something actually on top - if theres a jumper as you said there is then that should be enough anyway....

Seriously?

I was going to be that brutal but than I thought 'No, I bet thats how a lot of people break mobos in a noobish way' Lol.

I'll try that than, and do the caps again just like the Manual says.

Disable onboard vga if you're not using it.
If you run 1400x900 resolution, there is a bios update for it.

Also if you have a scanner/printer, try disconnecting it, they can cause problems booting up, but usually after the post screen, so probably nothing to do with it.

Man it took ages to read all that. OK so the only problem is that the monitor doesnt receive a signal from the video card?

You seem to have a motherboard with on-board vgs - disable that - some one said that above. also is it an LCD panel? If so are you using a 15pin DSUB or DVI cable to connect?

If you still cant get it going thru your graphics card, try plugging in the monitor thru the on-board VGA and see if you get a picture.

My Radeon X850 Pro doesnt actually signal my NEC LCD to power on thru the DVI. I have to have both DSUB and DVI cabled plugged in to see my POST and bootup. Once it enters windows it automatically switches to the DVI.

Right well first things first.

Took the CMOS battery out, okay for not as long as an hour but I also did the uncap thing, as said to do in the manual.

Basically it loads up with:

'CMOS Checksum Bad
CMOS Date/Time Not Set'

As for the monitor, it's a CRT 17", and I keep the resolution at 1024x768.
I've also tried plugging the monitor into the Mobo's own onboard GFX, but nothing would show up, even if it showed up on the GFX card.

As for changing settings in the BIOS, the monitor goes blank yet again if you save the settings..

Bad checksum? So reseting the BIOS using the jumper on the board didn't help? Did you set the BIOS up correctly with time and date after it was reset, save and reboot and you still got bad checksum?

Well, I set the correct time and date, and exited BIOS with saved changes. But when it rebooted it just went back to a blank screen

_________________

Hmmm, sounds very strange. You could try booting with the gfx card out and just the on-board VGA running to see if its interfering.

I had a quick google search for your motherboard model but I couldn't find anyone with similar problems. You could try posting on the ASUS forums...

http://vip.asus.com/forum/default.aspx?SLanguage=en-us

If you do make sure you post all component details and exactly what happens.

BTW how can you change the BIOS if you can't see the screen? Does it work OK when you reset the BIOS, but once saved you get no signal?

Exactly what it does, 9 boots out of ten and there will be no signal, but every once in a while it will load okay.

Plus it loads up fine after a BIOS reset, and will load to windows if you press to 'Load default settings'. Problem is when you shutdown the computer, it will go back to not booting up again. And if you go to 'setup', once you exit the BIOS setup the screen just goes blank again and windows doesn't load up.

I browsed through those forums earlier, using google and some of the words like 'A8V-VM CMOS Check Sum Bad' and it seems a few people have similar problems, but they go way over my head in technical talk.

As for my full sysytem, well I wouldn't be able to say for deffinate what my RAM is, all I know is that it's DDR 184pin 2700, but the two 512 sticks where bought at different times from different places and manufacturers.

This is the Mobo I bought though.

Atleast the BIOS error is gone. Do u see the POST screen? And then when it switches to windows it goes black?

Hit F8 and try and get to the safe mode options (I'm sure u hav tried this). If safe mode pops up...select Enable VGA mode and it should boot up.

Once in windows clean off ur Display drivers and try reinstalling them.

Failing that. Take any PCI cards off ur Moboard. Just leave the CPU, RAM and V Card. Try it again. Double check all the jumpers ( you never know).

Also, do u hav another machine that u can try the card in? Process of elimination.

EDIT: Above this post u say Windows does not boot up. Are u sure. Does the PC still buzz and whirr as tho it is loading? I hav had this problem before with my old Asus and I fixed it.

I don't see anything lol.

Basically imagine turning on your computer, and turning on your monitor, except your monitor is not plugged into the pc, it's a blank screen all the way.
