Its broken!

Linoge

Hey,

Was wondering if some of you computer geniuses could help me

My brother blew up the mother board on my desktop. Between it and two other spare computers at home I took different parts to make a better system for me and a lesser system for the house. Now both of them are broken!

I just cant see whats wrong with them. On one when they booted up, no screen is displayed, not even the boot sequence or bios. All the fans are going and I can hear the hd clicking, so I can't see why i cant see anything.

On the other when booted up, the same again, no screen is displayed, no boot sequence or bios, but as well on this the cpu fan isn't running. The rest of the fans are running. It was working before, and I do have power running to it. I just dont understand it

And finally! I'm just thinking now that it might be possible that the mobo isn't blown. My bro was just checking the ram, but when he put it back in it wouldn't boot. The bios is giving long beeps continuously. Does this mean its blown? I always thought it was one long continuous beep for that. Checked the bios oem page and they didn't have an error description for long (continuous) beeps.

Any suggestions about how to fix this would be really appreciated!

Check if the cables for the HD and cdrom drives are in properly, and in the right way around. Some IDE cables have a blanked off pin, but more dont.

Those symptoms might suggest the 2x2 4pin connector isn't in right so the CPU isn't getting power. The rest of the system is getting power from the 20pin connector.

might be RAM? and look on the website not manual,

also, sounds stupid, but when I have long beens on one of my old pcs it's usually a Graphics card not sitting properly, try to put it in firmly

• Maybe one of the components was short-circuited? Can happen if you're careless, especially with RAM.
• If the harddrives are powering up, it doesn't mean your CPU will. Is it seated properly? (you didn't force it, surely!)
• Are you absolutely sure all of the components are suitable for each other? I.e., you've got DDR/DDR2 RAM in a compatible motherboard, and the correct CPU (AMD/Intel), with the correct no. of pins? (I know I'm being patronising, but still...)

  Are we talking smoke and/or fire here? :eek:

Now, on to a simple POST (Power On Self Test):

• Remove everything from the motherboard except RAM, CPU & monitor.
• Check power connectors.
• Turn on system.
• Pray (optional).

If it powers on without alarming you on their status, you can probably rule those two out (and give yourself a pat on the back).

The IDE cables that I have have blanked off pins, thanks though.

I've checked the connection again and again, nothing changes. Will check again though, thanks.

Thought it was the ram alright. My bro had taken it out and I only have him to believe that he turned it off first. I would have thought that ram was hardy enough though. I've changed the ram in the mobo twice and it gave me the same beeps, thats why i'm thinking it has to be the mobo.

Did check the webpage btw, might try to dig out the manual, might be better!
Graphics card is well in. Plus, i've 2 different cards, which i have tried in both. No change. Thanks though.

I was careful to ground myself etc and i'm dealing with 3 mobos here. Hoping that at least 1 would work!
CPU was never taken out of any mobo so I dont think thats not an issue i dont think.
Memory is all ok for the mobo.

Not sure about the smoke and fire. Must ask my bro!

Will do that the POST test. Thanks for that. Will defo be praying!


Thanks lads for all your help. I will prob end up stripping it and putting it back together to rule everything above. Thanks again!!

reset the CMOS on the motherboard and then try booting it again

Sorry, but i'm a nooooob. Is that just a matter of taking out the battery or pulling out the chip, or how would I do it? Thanks

cdebru

two ways
first turn off the PC and remove the power cable

one is the cmos jumper usually it will be on pin 1 and 2 move it to 2 and 3 for about 30 seconds then move it back

the second is with the PC off power cable out remove the CMOS battery wait for 20 seconds put it back in

then reboot the PC see if it made any difference

Thanks for that cdebru. Will try that over the weekend.

Take out the memory and reboot.If the beep is the same you know its a ram problem.if not then its probably graphics card.Is the ram in the right sequence,dimm1,dimm2 etc?

Did u check for bent pins in the monitor cable?

Is the cpu fan cable unplugged from motherboard or if not put it in one of the case fans receptple if it reaches.
