Hi,
I get a failure to post when I switch my computer on (I put it together in December 2004, I have not added anything in the last couple of months or so, although sometimes the computer would shut down by itself at night for reasons I could not figure out). No beeps (as far as I can remember the computer beeped once when it used to start correctly), the MB light comes on,the fans come on and in the beginning the HDD light just came on and stayed on. I started by taking off all the pci boards. I reset the CMOS by unplugging the computer, taking the battery out waiting for 15-20 secs, resetting using the jumpers and putting the jumper back in the original position. I even tried booting without hard drive and optical drives and floppy drive. As a last ditch I took out everything except cpu and tried to boot. I have tried to push down on the power connectors and everything I could imagine no luck, no beeps. I strongly suspect its the Motherboard. It could also be the memory or the PSU or the CPU. I don't have spares of either. I have tried the graphics card in another computer and that seems to work. Here is my system configuration

-Aus P5P800 865PE with AMI bios
-Coolmax True power 2.0 550 Watts power supply
- P4/3.2 Ghz 800MHz LGA775
-Mushkin pc3200 DDRAM - 3-3-3-8 timing (not a verified vendor by Asus but it has worked fine for close to two years)
-3-hard drives - 2 PATA and 1 SATA and 2 Optical Drives and floppy drive
-Radeon 9000PRo graphics card (the fan on the card does not come on. But the card works on another computer without the fan coming on)

Any ideas? should I get one of the computer stores diagnose components? should I just buy a new MB?

Please Help

I had the same problem, and I bought my computer in November '04, guess it wasn't a lucky quarter for PC buyers. anyway, I personally suspected it was my processor but I never found out because I fried my motherboard when I tried. only thing I could do is put it in a new motherboard and see but can't be bothered to waste the money. now I'm just getting a new CPU, mobo and graphics card, which should be fun

Quickly: No beeps sounds like your processor to me.
