When I power it on, the fan, power supply, hard drive and everything turn on. The hard drive does its beep, the ethernet card lights up, etc. However, the video card's fan does either a partial revolution or none at all, and then stops. When I was able to boot it up, I always knew that it would when the video card's fan kept going. Sometimes If I held the power on button a bit longer it would jump start the fan (it may have not started going at first, but a second later it did). The LED on the monitor just flashes at me (which means it is not getting a signal or any information).
We at first thought it was the motherboard. We got it replaced. Nothing. Then we thought it was the video card. I just got its replacement in, and that didn't work. We have tried the removing the sticks of RAM and just trying them independently. Nothing. The power connectors should work, because we also got replacements of those, and they worked with for example the DVD drive and the hard drive. We also tried a different monitor which we knew worked. Still nothing. I unplugged everything from the back except for the video card, power supply, monitor, mouse, and keyboard (and there are no other cards within the system). It still did not work. I feel like there is nothing left to try. This weekend we're going to try a different power supply just in case its not getting enough power, even though I think that it should be capable of giving enough power.
Below is a list of the hardware in the computer.
Logitech Labtec Internet Desktop Keyboard & Mouse
Microsoft Windows XP Home Edition OEM Version
Corsair Value Select 512MB PC3200 DDR 400MHz CL2.5 (2x)
PNY Personal Cinema FX 5700 128MB AGP (The video card)
Chaintech MK8M800 Socket 754 Motherboard
AMD Athlon 64 2800+ Socket 754 NewCastle CPU
Toshiba 16x Dual Layer DVD +/- RW OEM Black
Codegen ATX Mid Tower Case, 400W, Front Media Port
Maxtor 120GB EIDE HD 7200/8MB/ATA-133
The power supply came with the case, and the 400W is the maximum. I believe the more realistic figure is 350W.
The processor is a 1.8GHz I believe.
The system requirements for the video card are as follows.
* Microsoft® Windows® 2000, or Windows® XP
* 800MHz Pentium® III / AMD™ equivalent processor or higher
* 128MB system RAM (256MB or higher recommended)
* A 250W system power supply
* A motherboard with an AGP 2.0 or 3.0 slot
* 5 GB of available hard disk space
* DVD±RW/±R/CD-RW (for users who want to watch and/or create DVDs on their PC)
* A free USB port (required for remote control)
* DVI or VGA compatible monitor
Please help and if you have any questions I will be checking often.
If the second power supply does not work, I might see what Best Buy's policy is for fixing computers.
