I hope some one can give me some advice. My computer was put into storage for near on three years. I got it out last march and it started no problems. I have recently pulled it out again and when I turn it on it starts to load then stops and the hard drive keeps starting up as if it is trying again to load each time it stops. I thought it may have been a battery problem so replaced that. I have removed all cards out of the PCI slots and replaced the IDE cable. All the drive lights come on and you cant put any disks in as it turns off before loading them. Each time it restarts it goes for less time till eventually it just sits. The most it has gone to is the screen which shows the options of loading windows by the last known good config, safe mode etc. Have tried moving the ram around only using one in the first slot but nothing seems to work. Have also unplugged drives and the same thing happens. When i have left it off for a while I have enough time to get to the bios but shuts down before I can save anything. I am thinking it is hardware rather than software because as I said its at a different place each time. PLEASE HELP!
