Solve : PC mysteriously crashed and has not powered up since? |
|
Answer» DUAL boot Windows XP / Linux Soyo Dragon 2 KT880 MB 1.5GB RAM, dual channel 512x2 + 256x2 Coolmax 400W power supply The computer powered off in use without warning and has not successfully powered up since. On pushing the power button, the fans spin and the hard drives start to spin up but everything stops and powers down before there is even a BIOS display. Attempting to power up again rapidly, while the drives are still spinning, doesn't change anything. On the theory that the power supply MAY be worn out, I have disconnected all hard drives and disc drives to see if it would at least get to BIOS, but the same thing happens. Transplanting with a power supply from a computer that works doesn't change anything. Replacing the CMOS battery has not changed anything. Using the clear-CMOS jumper does not change anything. I have not changed any hardware or major software recently. I GOT a battery UPS a few weeks ago but I doubt that would affect anything. Thank you for your time.I would do a visual inspection of the motherboard. Look for any blown capacitors. There don't seem to be any damaged capacitors, but I suppose the bulging ones could be difficult to spot. I've discovered that if I do not connect the secondary motherboard power cable, everything starts up normally but it doesn't actually boot up. I'm not sure that really proves anything useful.Remove power from all drives, remove all RAM sicks except for 1, connect keyboard & monitor. See if it will POST. Also, check your connections. This was similar to yours (see #11): http://discussions.virtualdr.com/showthread.php?t=249180Then swap in a known good PSU of the same or greater wattage...borrow one since it may not be the culprit.I've moved several of the RAM sticks around among all the sockets, removed the CMOS battery, and traded out for another power supply. Nothing seems to have changed, no boot, no chirps. I suppose it may just be dead then, I think I backed up everything important about a week before this happened so it's not too bad. I've owned a few SOYO MBoards in the past and never had 1 give up the GHOST on me... However judging by what you've tested this may well be the case... A local PC shop can test it for a nominal fee to determine if it is in fact the MBoard. At any rate Best of Luck...Quote from: Computer_Commando on July 20, 2011, 12:41:56 PM I would do a visual inspection of the motherboard.

If possible, try reapplying THERMAL paste. But first check the bristles like of your processor for any dust,oxidation or broken pins. |
