-------------------------------------------------------------------------------- Is it possible for a PSU to power up the fans, yet still be defective sometimes, and not produce enough power to boot the machine?

yes as your system is a low spec, that PSU may power it, however, try using a simple cheap multimeter to check the output voltages both with the system assembled & switched on and with all equipment disconnected from the PSU and that PSU has a really low output on the 12V+ rail (13A) what are the results of the multimeter test (both connected & disconnected) BTW you may find that 1 or more outputs from the PSU is 0 (zero)
Hey donkey. I was jsut wondering if there were any conventions for the number of amps going through teh rails in your average PSU?
That information should be listed on the sticker on the side of the PSU. If a PSU doesn't provide enough juice to get the system going completely, a common sign is the fans spinning, but the motherboard not POSTing. You don't have a super high-powered system, but it's quite possible the PSU, while a fine unit, is simply incapable of providing adequate power for this system.
23/08/07 Hi PSU Couldn’t get a Multimeter [live in Spain – closed for August, the country that is] Took Power supply from another machine No Branding, just MODEL LPT2 [Googled, nothing] 300 Watt Sounds healthy Turns the fans Good draught from PSU Fan Graphics Card Took from another PC RAM Took ddr400 from another machine HDD Put into another machine as Slave Run Chkdsk /r Comp Mgt > Disk Management Healthy NFTS 4 Partitions Copied file to it – No problem Seemed AOK BIOS Managed to get into BIOS sometimes [though most times it went to black screen] Loaded defaults Changed Boot Order Floppy/CD/Disk 0 Disabled SATA POST Found Boot OK on IDE 0 Operating System missing Install Operating System W2K from CD Boot Run straight through to ‘Starting Windows 2000 Just hung Enable SATA in BIOS POST No Sata or Pata found Boot from CD F6 Raid disk from ASRock Website Installed from Floppy Run straight through to ‘Starting Windows 2000’ Just hung Got back into BIOS Changed setting from PCI to AGP Rebooted No Change Found Boot OK on IDE 0 Operating System missing Install Operating System W2K from CD Boot Run straight through to ‘Starting Windows 2000 Just hung Boot from Seagate Disk Wizard cd [Downloaded from Seagate site] Loads Hangs after few minutes [Progress bar to about 1/3] NEXT STEP ??? not done yet Put Hard Disk into another machine Reformat to single Partition Put Disk back into machine Try to Install again Getting Desperate COMMENTS When it is doing something, like starting Windows Setup It goes like a rocket No Display problems Just wont do the rest.

I am in the wilderness there. I have an Emergency Boot CD that will give me a lot of Info about the computer, but a lot of it is over my head However, if someone can think of a Question, il get the info. I don’t expect miracles, [I have started praying for them though] I have tried everything I can think of Any thoughts will be welcomed like fresh air on a thick smoggy day Cheers Kevin
as far as i can tell, your PSU is from a company called: Power Link International LPT2, i think this is their website BTW: have you tried reseting the BIOS / CMOS, failing that, i would say it is probably the PSU
