cpu mobo buggin out.

[aintnothang]

Ok, so I got my new replacement hdd from seagate today and hooked it up. But now I cant get any display from either of my video cards. It was buggin out earlier and I thought since my hdd was bad this was my problem. When I turn it on there is no display and the fans rev up and down up and down. Could this be from a faulty mobo or cpu?

What happens if you pull out all the drives/etc?

[aintnothang]

including the ram and gpu, just leaving the cpu mobo and psu?

[x88x]

Well, it'll need RAM to do anything but beep at you that it doesn't have any RAM, and it looks like your MBB doesn't have onboard graphics, so you'll need to leave that on as well.

[aintnothang]

so just disconnect the hdd and cd-rom?

[x88x]

Yeah, and any other add-in cards you might have. Also, if you have a system speaker that you can hook up, do that. It might give you some useful beeps.

if it beeps at you your ram is bad. i just went threw this. if it just wont boot right its either a dead cpu or a dead mobo.

[aintnothang]

how can you tell the difference between a dead mobo or a dead cpu?

[blaze15301]

you have to swap them out pretty much.

[blaze15301]

do you have another mobo or cpu you can use if you have one or the other your set pretty much.

I find that a good can of RAID often helps when my computer starts buggin' out on me! Just open the side panel and let it rip!

My advice when stuff goes awry is actually to just take it all apart and put it all back together again. And I mean everything. If that doesn't work, then try going to the extreme and even redoing your heatsinks and thermal paste. That almost always does the trick for me.

[blaze15301]

lol we have the same philosophy..... never thought anyone else took the time to do that

When something on the MBB is bad, I've found that it will normally do something. If the CPU is dead...it won't.

[aintnothang]

Shame is I dont have another mobo to test it with. I might try to pull it all apart then reassemble it later today or tomorrow after I'm out of class. Could it possibly be a short?

[blaze15301]

its hard to say. ive had some pretty odd things happen to where i still cant explain what happen. ive had my entire computer freeze and would restart,and all i did was wiggle the monitor cord going into the video card and everything worked.

[aintnothang]

So I disconnected all the drives and no sound out of the speaker. But the fans still rev up and down continuously. Tomorrow I will tear it down and rebuild.

[x88x]

Come to think of it, it almost sounds like it's continuously rebooting...check all the power connections; make sure nothing's loose.

[blaze15301]

i secind x88x.s idea

[aintnothang]

ram was unseated. So now I have to install the new card and drives and install vista.

[Zephik]

Ah, the old RAM not being seated correctly problem. I've had that issue with my laptop before, but with different results. That's something about PC's I don't like. It could be a problem you've had before but with totally different symptoms! Annoying! lol

[blaze15301]

lol ive done that on my first build. you need to watch doing that tho you can fry everything from a short.

[aintnothang]

what can make it come unseated? just from moving around. Im sure this isnt the last of my problems.

[x88x]

Heat, movement, vibration, pagan gods, idk. When I was in charge of maintaining the computer labs on the college campus I was at, we had probably about 3-4 of the new computers each month that would suddenly stop working and had to have the RAM reseated.. Maybe they just weren't put in firmly enough at the factory or something, idk. /shrugs

[blaze15301]

yeah any thing really can make them come loose. kinda like a screw in a chair or some like that they just come out eventually.
