DEAD COMPUTER, SUSPECT MOTHERBOARD

[flyted]

Home built with Asus A7N8X, Athlon XP-2800, (2) 1GB memory sticks, ATI 9250 video card, 400W ps. Also been on high quality surge protector, line conditioner and UPS since new. Never been overclocked or overheated, temps are always low do to excellent due to excellent cooling. Unit is 4 years old, the only symptom was about 1 month ago it started not wanting to shutdown and would reboot just a second before turning off. I ran anti-everything, removed all programs I didn't need, ran CCleaner and did a XP OS repair. The shutdown issue only got worse, but that was the only symptom everything else worked great. I did notice the fan on the video card never seemed to be running but since I don't do video games I assumed it was temp controlled. Now, the only way to turn on the system is via the ps switch, the front case panels dont work and no video or HD noise. No smoke, no pops, no burnt parts on the MB, All the fans spin, the green standby power light is on, all the voltages from the ps are correct but nothing else happens. I removed all devices from the motherboard and the battery to let everything reset, still no luck. I had also just ran the extensive smart program from WD for the HD a few days earlier and no issues. 1) could a bad video card bring down the whole MB? 2)How can I verify its the MB before I buy a new one, I plan to keep everything else as I like it? Never had a failure like this before.

Thanks

1. DON'T POST IN ALL CAPS!

2. Sounds to me like the fan on your video card failed, and then the video card fried.

3. There is no way to tell, no matter how amazingly experienced we might be, what exactly is wrong with your machine without actually testing it. Basically you need to start swapping parts until it works. Swap video cards, does the new one work in your machine? problem solved. Does the old one not work in another machine? problem identified. (most likely, unless it has compatibility issues with the other machine). Swap the mobo, swap the ram, swap everything step by step until it works.

Sorry about the caps, didn't realize it until I started typing the text. Spend a few hours straight working on an issue and getting nowhere and you might actually make a mistake also.
