I built a computer back in February and have been trying to get the thing to work since then. At first I thought it was a power issue, but now with an 850W PSU there is no way its a power issue. All of the components power up and the fans start whirling, but it won't post. Every once in a blue moon I have been able to get it to post for some seemingly random reason, and was able to install windows xp on it. It ran fine as long as I didn't turn it off and then when I would the next time I tried to power it back up it would be the same old no post. No connectors were touched,nothing was changed. First of all here are the system specs: 850W Thermaltake Toughpower PSU Asus A8N32 SLI Deluxe Motherboard AMD FX-60 CPU Nvidia Geforce 8800 GTS VGA 1 GB Ultra Ram 1 750 GB SATA Seagate HD I've contacted Asus and they were of no help. I rma'd the board once and got a new one back, same problem. I upgraded psu's to a 650w and finally this current 850w just to make sure it wasn't a power issue. I've reseated everything inside the case multiple times and that doesn't seem to be the issue, this includes the vga, memory, cpu, and all of the various power connectors. I tried holding the sata cables to make sure they werent loose during post and it didn't seem to help. I took it to a guy here in my city to check it out and he couldn't find the problem either. He got it to post as well, but basically said he didnt know why it wasn't posting. The easy plugs are in the board so I know thats not the reason, and I checked the connectors inside the plugs to make sure that they would be actually connecting. I dont know what else to do.
