Was contacted by a friend who has his computer go cold on him and asked if I could come check it but he was sure it was the power supply that died. At this time, it was not responding to any input, so I opened it up and double checked all the cables and that the power switch cable was connected. Still dead, so replaced his Hairong ATX-480W with a Coolmax V-400. He really wanted to get it back up and running that day and the only PC shop in town sells this model only. I was worried it might not be enough power and it was not really a top brand PSU.
Installed the power supply in his system, and it booted up first time with no issue other than there being some pretty good air noise from the power supply fan. 2.5 months have passed and he called me saying his computer is "going black" and he thinks the hard drive might be dying.

Coolmax V-400 power
MS 7309 v1.3 motherboard
Athlon 64 x2 5200
2x1gb ram
Serial Adapter card with 2 serial ports
Firewire adapter card
Twin CD-Rom drives(IDE)
Twin 120gb seagate hard drives(Sata)
Zip drive(disconnected and used to cover 3.5 hole for now)
Floppy drive
Single rear 80mm fan
On to the symptoms....
Depending on what seems to be blind luck, the system can do different things on boot including:
1. Boot up and into windows just fine and provide a random amount of time(up to 1-2hours) of use until it either goes to a black screen or simply reboots. No entries are found in event viewer.
2. Boot up, then between post and windows, drop again to a black screen. Once at the black screen no input is recognized and the cd drives won't even open. Reset also does not respond at this point. Only holding the power button works.
3. Power on the fans and CD-ROM lights up for a moment, however never post or beep. Fans spin and no response is given from the system.
Once the black screen is reached, the HDD light stays solidly lit even if there are no drives installed in the system. I tried to run memtest with nothing in the computer except for the cdrom drive, floppy, ram and cpu. It never posted and HD light was solid with fans spinning. I turned it off for a few minutes, tried again and memtest ran for 3hours with no issue and memory seems ok. I was thinking since it was rebooting that it may have been ram.
Hard drive possible issues(2 years old):
- passed Seagate's diagnostics and tests, currently copying to a backup drive just in case.
- was making tremendous noise and extremely fragmented in his computer the few times I got to windows
- making very little noise at all now that it is on a transfer cable on my desk and backing up to another drive
- not sure what to make of the drive acting so terrible in his computer but then being quiet out here besides the reboots severely fragmenting the operating system/pagefile.
The hard drive will sort itself out I believe either by transfer to a new hard drive or fixing the booting problem.
My only three theories are the motherboard is going bad, the power supply is insufficient or bad already after 3 months, or there is a short possibly somewhere in the case. The randomness of the issue is what is puzzling me however. It can act completely normal and fine(except for the disk check and slowness from fragmentation) and then next time refuse to post completely.
