View Full Version : Put in a new 8800GT and took out will to live!
Hiya people of Aria, in need of a bit of support please!
Heres the predicament:
I recently bought a 8800GT and 2gb of RAM that crucial found as suitable for my motherboard.
Upon installing everything the whole PC just won't start up at all. No beeps, fan movement or anything! Nothing at all - as if it wasnt even plugged it.
The RAM was fitted in fine and was recommeded as compatible.
The 8800GT fitted in fine with room to breath and using the 6pin adapter to plug into some spare 4way thingies.
Everything looks OK but the PC wont turn on.
Here's what I have tried:
To try and find the cause of the problem I have tried changing back to the old RAM - Still nothing.
Unplugging the 8800GT power cables [because apparently even when they are NOT in the PC should boot up but make 3 beeps to say theres a problem] - STILL nothing.
Here's my system specs:
3.2gig Pentium 4
450 PSU
[NEW] 8800GT / Was using a really ancient Radeon X800XL
[NEW] 2 x 1gig of DDR2 Ram / Was using 2 x 512mb
Foxconn motherboard [cant remember the complicated name, and its hard to find out without normal PC up and running!]
Thanks so much for any help you guys can give like!
Does it still work with the old memory and graphics installed?
If so change one thing at a time, starting with 1 stick of the new memory, if that doesn't work try the 2nd stick of new memory if that works then one of the memory sticks is dead. If the memory doesn't work at all put the old memory back in, double check it still works, then replace the old graphics card with the new one. If that works then the memory is incompatible with the motherboard, if it doesn't then the graphics is either doa or incompatible or your psu just isn't man enough for the job, though as you say you should get sign with the psu unplugged, do you know what make the psu is? I am guessing dead / incompatible gfx.
Other options are to check the new items on a second pc, if you have access to one.
it may sound a little small, but check to make sure you havent accidentally knocked out the small wires which connect the power on button, reset, and LED's to the motherboard.
I would also try another PSU to eliminate that, and another power cable / fuse too. If the PSU is a generic one which came with the case it may be the case you have either blown the PSU or the power cable fuse.

I have tried old RAM and still got no response. Its as if its not plugged into the mains, only it IS!
I can't be certain, but even if the graphics card has no power / is dead, shouldn't the fans atleast start up or something?
The reason I ask is because its going to be a right pain taking out the 8800GT because its so wide that its fan covers the little release trigger [which is hard enough to use on its own anyway!] making it pretty impossible to release it!
I couldn't see a problem with the Powerbutton/LEDs connection either.
Can a PSU die without even making a sound?
Thanks for the replies guys.
I'd go back to the old setup of memory and graphics just to be sure, at least that way you know the rest of the pc is still working. It could be, as cleggy suggested, just a fuse OR if the psu is some generic one that came with the case, a fried psu as the 8800's are somewhat power hungry beggers and you really need a branded psu of some description. If it all still works then try my suggestion of changing one piece at a time.
Fuses can blow without a sound, next thing to do is to check these :)

I'm on it right now :>
EDIT: Just tested all the cables and sockets and they are all working fine.
Just spent a failry long amount of time trying to get the 8800gt out without damaging it.
The little release trigger that hooks the card in falls perfectly between the big fan and the card bit of the card. Its totally unreachable for a human hand. So I tried releasing the catch with force from the other side but its just not happening. Seems the GT is only coming out in pieces and I'm not ready to do that yet!!!
So the long and short of it is, I can't test my old graphics card in my PC. I'm not too concerned though because I think I would get -something- even if the card was totally dead when I pressed power. Just something like the LEDs or a spinning fan.
if you can get to the cables on the mobo, that connect to the switched on the front, try shorting them to see if you get anything. Could be your power button has broken. When you plug the Power cable in and turn the PSU on do any of the fans spin? on anything?? If not then i think you have a broken PSU :)
if you get nothing at all no beep fans etc evin if for a millisecond then id say mobo or psu . a dead cpu/ram/gfx will still allow a mobo to power up . what wattage is the psu ? is the motherboard shorting onanything ?
PSU is a Antec 450W.
After I had put in all the new stuff, I put it back onto my desk, plugged in all the cables etc. Pressed the power button and it was as if the mains house electricity socket hadn't been turned on. Absolutely no response. Not a millisecond of light/fans/anything.
Theres are chance that its the power button cables but they are a right pain to reach and I have no idea how to get to them / use them!
Thanks again for the help guys. I would have been lost a long way back otherwise!
OK guys, I'm probably going to try and solve this problem by throwing money at it!
How this for a new PSU
http://www.aria.co.uk/Products/Components/Power+Supplies/500w+%2B/+Xilence+700w+Gaming+Edition+PSU?productId=26715
Suitable or not? If not this what would you guys suggest?
Thanks!
take the motherboard out of the case , place on a piece of cardboard or a towel or somethin . connect everyting up and try that to rule oun the motherboard shorting on something in the case . Also do you know how to turn on a PSU without connecting it to the mobo ( to test that it works ? )
a 450w antec would defo be sufficient for that setup

Your Antec PSU is fine, I had an 8800GT on my 430W.
Have you tried singling out the problem? So make sure it isn't the RAM that's stopping it from booting?
try what GM8 said coz it could be the motherboard making contact with the case or something my mates done exacally the same thing

the case switch may have failed! take a flat blade screw driver and touch the 2 pins that the power button cables connect to... if it posts then the power switch has gone which measn new case or attact a switch elsewhere.. simple!
You could try this first http://aphnetworks.com/tutorials/psu_paperclip_trick

I have a spare one that may fit your case if you are interested.
