Re: Computer will POST only after a dozen boot attemps
Hmmm sorry for reviving this thread, but it would be nice to move it to the: "Power Supply Design and Troubleshooting" forum. I think what happened to me might be a very common problem; many persons out there might have a bad PSU that's causing a similar range of symptoms.
By the way, I'm still extremely happy of my new Enermax PSU. It outputs a VERY stable signal, no interference whatsoever. It was extremely easy to install (and the manual was very complete). The computer's behavior is back to norm...

Re: Buying a Sparkle SPI ATX-400PN
I had a bad experience with Fuhjyyu caps in a Deer unit. I live in a not-so-big town with only a few decent computer shops, so the choices are limited. I think I'll stick with the higher end Enermax (at 70-80$).
Anyone has a pic of the inside of a Enermax unit? And what kind of caps do they use usually?Leave a comment:

Buying a Sparkle SPI ATX-400PN
Hi! I want to replace an old crappy PSU in my secondary computer, and I don't want a high-end model.
(I've installed a Enermax in my primary computer and I'm very happy of the results (it's very stable, not noisy at all, and was a breeze to install) but at 70-80$ it's expensive.)
So I've found a computer shop where they sell OEM parts (without the nice looking box and booklet) and they had a few Sparkle FSP/SPI ATX-400PN 400W in stock.
Now at 40$ it's very affordable, and I've seen a few good reviews of this model on the net, but is it a good solution?... -
Re: P4B533 fan spins no post
From my recent experience, I'd recommend trying the mobo with a different/new PSU. Just in case the "no boot" problem is related to bad caps in the power supply.Leave a comment:

Re: PCV-LX920 BOOT DISK FAILURE!!! Caps??
Hey, it looks a bit similar to the problem I had in the last weeks: computer will only boot after a few tries. It is discussed in another thread -- we've finally figured out the cause was a dying PSU (power supply unit). The autopsy revealed 3 bad caps in the PSU.Leave a comment:

Re: Epox 8kTA3 - worth repairing?
Huh, but is this motherboard USB ready? One thing for sure, a 1998 or 1999 BIOS would probably not let you boot from USB.Leave a comment:

Re: Computer will POST only after a dozen boot attemps
For the record, here's a tentative picture of the 3 caps. Unfortunately, the goo over the 2 caps on the left had dried, and it partly went away when I cleaned up the board with a vacuum cleaner....Leave a comment:

Re: Computer will POST only after a dozen boot attemps
There it is:

It's about the least expensive of their products, but it's got the same quality as the more expensive ones.
Nice little thing. Saved my computer's life.
And it was a pleasure to install.Re: Computer will POST only after a ...heir products,Leave a comment:

Re: Computer will POST only after a dozen boot attemps
Was Enermax a good choice, then?
The only other option in the hardware shop was a 160$ PSU with a front panel display of the temperature and a knob. Nice, but too expensive for me.
I live in a not-so-big town so the choices are sometimes limited.
But I wouldn't trade the landscape for more computer shops!Leave a comment:

Re: Computer will POST only after a dozen boot attemps
This PSU is probably worth 15$-17$, I wouldn't bother recapping just for the fun of it. At least I know what failed -- the capacitors. But I'd say this PSU was producing low quality voltage from day one; it just doesn't filter right.
I've just realized how computer shops can come up with "fantastic offers" by using some cheap components where the customers won't look (PSU, USB cards, generic components such as CD-RW players). If you choose an excellent motherboard with the best CPU around, it's almost...Leave a comment:

Re: Computer will POST only after a dozen boot attemps
Yayyy! I've installed a new PSU and the system boots normally now! Even better, there used to be a slight case of interference on the monitor, and now it's gone! This system has always acted kinda strange. It's 2 1/2 years old but I suspect some of the components are older. In the past months this system suffered from a dead monitor, a dead keyboard, 2 dead CD-ROM drives. A serial killer feeding on peripherals.
My new PSU is a 350W Enermax with a lot of cool options. It's got a dual fan, is adjustable, not noisy...Leave a comment:

Re: Computer will POST only after a dozen boot attemps
Well I'm happy if the problem isn't capacitor related.
What type of PSU is good for a Intel P4? 400 watts?
I'll change the PSU and the BIOS battery, just in case. Just one stupid question: if I remove the BIOS battery, will the BIOS lose any information?
I've assembled or repaired many computers, but I'm really not an expert on components and electricity.Leave a comment:

Computer will POST only after a dozen boot attemps
Hi! My computer has been acting strange for a few weeks now. My caps look OK but here are the symptoms.
When I push the ON button, it powers up properly: the PSU fan starts, keyboard lights flash, the hard disk makes a sound and the internal speaker makes its normal short beep.
Then........ nothing. The screen stays dark and absolutely nothing happens. The keyboard and the mouse aren't powered (no reaction when I press the caps lock key). No POST, no more hard drive noises. The PSU fan is still running and a few diods are on, but that's all.
I then...
