Hi, recently changed my motherboard. Got everything up and running and it was fine for a couple weeks. Then my power supply and cord that was attatched to it blew so I bought a new psu ( 450watt ) and put it in and it was fine for an hour. It reset while I was playing warcraft 3 then I went into the bios to changed something ( can't remember what ) but it wouldn't start. I went back in and changed everything to default then saved and exit. Now the screen gets no signal but all the fans and lights are on. I've tried the psu,vid card and ram in a athlon 1800+ and a celeron 1.3ghz and their all fine. I've also taken the cmos battery out for the night and put it in when I got home from school.. yet no change. I should also mention my dvdrw opens but my dvd drive doesn't I've tried unhooking the dvd drive but still no luck. Any help would be appreciated, thanks.
My specs:
Athlon 2600+
1gb ram ( 1 stick ) brand is legend
geforce ti4400.. =(
80gb hd
mobo is an albatron KX400-8xV Pro

If you need to know anything else tell me ill do my best to find out although I'm not too great on computers... still learning =P

First are u check the mother board espesifications is same as you change? Because the old have different drivers and the new have other you can star for that format and install drivers again maybe you have confict between old drivers and new if you what more info please email me at [email protected] or contactme on messenger thanks

Ended being a leaking cmos battery.. these forums are rather useless arnt they? That last guy told me I should re-install windows even though I couldn't see the post just saying this cause there might be other people with my problem.. rip out your cmos battery and check the bottom of it for any spills and clean your batery holder with alcohol

I wouldn't say that they are useless. I would have mentioned the CMOS battery to you as it was the most likely way to reset your system after your botched overclocking attempt.

You said you changed the mobo so we assume it's a new one, that makes the leaky battery option even more remote.
