In theory it doesn't matter. In practice, bridge rectifiers use typically bigger diodes internally and the form factor allows for better heat dissipation and more current carrying than using general purpose diodes in a bridge configuration. Using discrete diodes instead of a single component bridge …

Yeah, you can often tell by just having a quick look in a PSU, whether a PSU is a complete gutless wonder or not. Things like missing input filters, using 4 x diodes rather than a bridge rectifier, wafer thin heatsinks, more board than component (like the L & C board). A bridge rectifier is …

Isn't the FX 5600XT just an overclocked die-shrink FX5600? I'm pretty sure the "XT" nvidias were always inferior to other versions. Default core/memory of 5600XT works at 235/200MHz, while 5600 works at 325/275MHz. Actually, by default 5600XT is even slower (though older) than 5500 (270/200MHz, …

Found a couple of these IDE mobile racks, always wanted one of these for my win98 build to fill out empty 5.25 bays, I guess you could plug a CF adapter inside too, but does anyone really have a use for these nowadays? A large storage drive for transfering CD images between builds perhaps. https:// …

1) The Libretto 50CT runs fine without CMOS battery. 2) I just checked the default behavior with no hard drive attached. First, it shows the BIOS version. Then it tests RAM and then flashes the "_" sign. If you try to turn it off at that moment id does a lot of beeps as described. 3) There are two …

A long time ago I made a *.bat script that copies autoexec.bat and config.sys into a folder named after current date on startup. It should serve as a working example, but I don't really remember the contents anymore 😀 I'll drop it here once I get home in a few hours.

I'm only taking a chance on this board because it's about as high end as Socket A gets, and thus trying to replace it would cost more than trying to fix it. Similar boards sell for $80 and up and I paid $47 shipped for this one. GA-7VT600 is surely good, yet I would not call it "as high end as …

As nd22 already mentionned, AthlonXP likes beefy +5V. That said, new PSUs hardly ever work with them. In 2014 I bought a new budget Zalman PSU only to find out it could not handle the load even though my motherboard (GA-7n400S) has a separate +12V header.

Do you even need a floppy drive? Once you have your system installed and configured, it's pretty much useless.

Guys, are you sure it's a good idea to raise EvieSigma's hopes? Let us be honest. The board is probably dead for good. If EvieSigma had the skill and the resources to fix it, he/she would not have made this thread.
