Hey all; After finishing lunch, then having a conference phone call with a Russian Oil Rig with a 1 second delay somehow it popped into my head that I really need to sort my home computer out. I've got this strange issue, When I start the computer, it will take several boot attempts before it actually starts. Here's the full step through story; Was running windows XP, turn it on, boots, gets to the XP loading screen, pauses, then reboots itself and makes that bios beep sound. Continues to boot again, gets to the XP loading screen, pauses, reboots making the bios beep sound (sound which is always made as the computer boots) and continues. After several attempts it decides it's happy and just runs normally no problems. At this stage the computer had been running at a server with no protection and I figured software wise it was totally fooked. Formatted the sucker and installed Ubuntu as the OS. Same thing happens. I turn it on, beep, starts loading at the Ubuntu load screen, pause, reboot with beep, continues. Does this 2 or 3 times before it loads properly. Now, what the hell is wrong with it?? Is it a bad sector on the HDD? The current HDD in use was the main storage HDD for the HTTP & torrent server so I was thinking the constant wear made have worn it out. Is it the RAM? Motherboard? What ever it is it has created cracks in the side of the case where I have tried percussive maintenance. Stats (if i can remember, its almost 3 years old). Asus MB (no idea on serial), x64 bit processor dual core AMD I think. 1GB Ram OS / Boot HDD is Sata 320GB. Power supply is 430W and pushing 4 HDD's, MB, very basic graphics card, wireless card, Raid card and rarely a DVD drive... (too much?) Any ideas computer Guru's? thanks in advance.
