Computer powers on for split second, then dies
Posted 28 October 2007 - 10:55 PM
Also, i'm not sure if this is relevant (i kinda hope it's not), but about a week ago I was playing B&W 2, (kinda graphically hard for the computer) and my computer just died. This problem I actually fixed, by looking inside my computer and finding it full of dust (the area between the GPU fan and heatsink was completely blocked off, so no air got to the GPU at all.) Given that, i decided that my gpu had overheated, causing the computer to automatically turn off. Once i had let the GPU cool down, and cleaned out all the dust, I booted up and my computer worked fine for about a week, untill this incidedn i just talked about.
Any help would be very much appreciated!

and yes, i agree with MO on this, id look at the PSU before getting a new GPU

after another 5 mins of tinkering, i think it turned out it was the graphics card. correct me if i'm wrong, but the fact that when i took out the graphics card it turned on fine (couldn't see anthing on the screen cause there was no graphics card), does that not mean that my g-card is shot? also, will this card work with the comp in my sig? it seems to have gotten good reviews and looks to suit my needs""
Could be that without powering your graphics card there was enough power.
Have you tried disconnecting all your drives except for what hard drive your OS system is on? Also- swap some of the cables around. Too bad you don't have a PSU checker- I got one just for this purpose, cause a bad PSU can look like alot of different problems depending on what voltages are affected.
Although a bad graphics card could keep your computer from posting I have not heard of it keeping it from turning on, unless the MB was bad.
It is becoming more evident that to solve this mystery you will have to start doing what MO suggested and swap out parts. You could also try taking your video card to another computer- an easy swap and it will tell you quickly if something is wrong there.

You can find less expensive ones also--
Anyway-- just some advice-- I spent $70 on a PSU when it turned out to be a bad memory module.

edit: also i'm tempted to think its the g-card, cause i did overheat it like hell the other day. it burned my finger
edit2: yes its PCIexpress x16
edit3: are there any things i can do with just my one computer to see whats wrong with it? unfortunately i don't have another one to swap with to check to see if certain parts work

It's probably why most of us keep extra parts around- just to make diagnosing easier.
