Mobo, CPU, ?? I am stumped.

I have a AMD XP2000+ with a Soyo SY-K7V DRAGON Plus! mobo. 2 sticks of 512MB of Ram. It was working fine until yesterday. Just died...beeps once then 2 seconds later it beeps many times and stops booting. Does not power down.

Replaced cpu heatsink and fan. Didn't affect anything
Took both RAM sticks out. Didn't affect anything.
Tried one RAM stick at a time. Didn't affect anything.
Clear CMOS. Didn't affect anything.

Tried CPU on another computer with other computer's CPU heatsink and fan. It worked. Tried "broken" computer's heatsink and fan on "good" computer...doesn't work. Tried good computer's heatsink and fan on "broken" computer and it doesn't work.

Not sure where to go now....

It's not the CPU. Not the RAM. Not the power supply.

The only thing I can guess is: it's the "broken" computer's heat sink and fan along with something else...I am starting to think it's the "broken" computer's mobo.

Any ideas or things I should try? This one has me totally stumped.....

 

Clear CMOS.

 

Already tried that and it didn't change a thing.

 

I'd say it's about time for a new motherboard then.

 

ya that's what i was thinking...just was hoping I was missing something....don't want to dish out more $$$ on this computer if i don't have too.


thanks for the help.

 

Happens to the best of us...I may have to replace my 4 1/2 year old Asus A7V here unfortunately.

 

Yeah, I'd say your m/b seems like the faulty bit here. I had the same trouble a while back and when I got a new m/b, all was well. But that was when I didn't realise that static in your body can blow your m/b ... I quickly bought an anti-static wristband! lol

 

Well, got a new mobo....and same prob....figured out it was something i never even suspected...the video card.

Never had a video card go bad on me...guess there's a first for everything.

It was about 1.5 yrs old (so out of warranty)....eVGA NVidia Personal Cinema FX5200 128MB video/video cap card.
