I have an old Pentium 4 PC that I wanted to use as a Linux machine. It has a Transcend 512 MB DDR400 DIMM RAM module, and I purchased the RAM module just a year ago, so I dont really think it could be the problem. Then there's a Seagate Barracude 7200 RPM 80 GB Ultra ATA drive. And the motherboards an Intel D101GGC. It has been a few months since I last used it, but just yesterday, I started it, and then, the moment I plugged it into the wall socket, the PSU turned on along with the CPU fan, but there was no beep. Earlier, whenever it would turn on, there would be a beep, a single beep, for about a second, but this time, there was nothing, and the monitor also did not turn on, like, it remained in standby. I tried shorting the PSU with the green and black technique, and the PSU turned on. I haven't tried anything else yet, but what could it possibly be? I need help here.
Well, It looks like your computer will take either pc-2700 or pc-3200 ram/memory.. I would try another ram, or test that ram in another pc, Next try another hard drive.. If its the Motherboard, It probably blown a capacitor, Which can cause the same problem. Its just going to be hit and miss here... First try another ram stick or test that one. Then the hard drive.. And Motherboard last.. Do you know what socket your Motherboard is ?
The LGa 775 socket is at least easy to find and does not cost that much IF you have to replace it.. Just make sure you buy a good Brand name.. Like Gigabyte or MSI or Asus..
Did you test your Ram and Hard drive ?Just because the PSU turns on, does NOT mean it is still good.. What is the make and model of this PSU ?
