ok so my computer died and i figured it was just a bad power supply. i got a new one and now it boots again but i get no video signal. no bios nothing

its a gigabyte board. i bought it like 3 years ago i do not remember what kinda. it has a 3500+ amd 64 byte cpu. i the video card works in another computer.

if i disconnect the HDD the mobo gives a constant beep. if i i dont put the power in to the video card the mobo gives the same beep. i did not have the speaker plugged in so i got no other beeps. i still have to try that.

does anyone know what this could be? i was thinking bad mobo or bad cpu what do you think?

how can i tell if the cpu is working? the ram?

any info would be great thanks
 
A constant beeping would point at the cpu, memory, or video card. That's the usual cause. You can likely rule out the video card having tried that on another system and found good.

Besides the cpu as the likely answer however you may be looking at bad memory. Try removing all but one dimm if you have more then one installed. The cpu would stall everything and sometimes sees a visual failure message come up onscreen when first turning the power on.
 
well i took the battery out and i got it up. but every time it restarts i have to take the battery out again or there will be no video out put. what would cause this? also when it starts up it says cpu clock is at 200 mhz it is a 3500+ amnd 2.2 is this normal
 
The 3500+ is a 2.2ghz Atholon model. The clock speed in the bios itself would be 200mhz for that model.

As I mentioned on the second thread you started try replacing the battery since a weak battery can explain a list of problems that can be seen since it maintains the cmos information. While the battery is out a charge is held long enough for replacement and a likely return to the factory defaults.
 
i have to take battery out to get video 1 time. then i have to take it out again.

i start it up, restart, no video, take out battery, replace battery, start up with video.
 
When you say replace battery is that the same or a new one? The problems you are having if you already went ahead and put in a totally new battery would be with the board itself. On one older build here the board ate batteries for breakfast after a few years of use. Sudden restarts or shutdowns while in the middle of something, the fsb setting had to be lowered from 200mhz down to 166mhz in the bios or it wouldn't even get past the post tests, etc..

At first it had appeared there that the cpu was toast upon seeing erroneous 74C then finally 85C cpu temps. Then the problem with lowering the fsb was the last straw since high temps were still being seen with a Zalman 9500 sitting on the cpu! A year or so after disassembling the entire case a fresh battery saw everything running normally again for the time being anyways.

Are you using onboard video or have a separate card installed? A flaky board that eats batteries will see problems with anything onboard.
