This is my first time at upgrading a PC and am having trouble from the start. Please excuse the long post.
I bought a new Motherboard (ABIT VH6-II), processor (PIII 1GHz HS+fan 370), and Micron 256MB DIMM PC133. I am attempting to swap these with the components from my old Pentium 166 Micron system.
From the specs everything seems compatible (ATX board, ATX PS, ATX, box), but when I finally installed all the hardware and turned on ……. NOTHING, as if there is no power. AH, but there was power, because the monitor LED light was blinking and the fans would turn about a half or a revolution and then stop.
I spent the last two days researching, until I happily stumbled onto this board. I have a few hunches and would very much appreciate some suggestions from the experts on how to proceed.
First the specs:
ABIT VH6-II 370 socket ATX w/ softmenu VIA chipset with onboard audio
Pentium III 1 GHz /133 MHz FC-PGA2 with HS and fan
Micron 256 MB PC133 DIMM
ATX full tower box w/ exhaust fan
ATX 250 Watt power supply w/ exhaust fan
Maxtor 11GB 5400 rpm disk drive ATA33
Diamond Stealth 3D 2000 4 MB grphics card (PCI)
D-LINK DFE-530TX PCI network adapter
US Robotics Sportster33.6 Fax internal (ISA)
Floppy
Hitachi CDR7930 8x (an old IDE)
I followed the recommendations in some of the posts about disconnecting everything except the MB, processor, memory and PS, and HD. That did not seem to help.
So here are my suspicions:
1) The system fan and PS fan are hardwired and do not have connections to the MB (3 prong plug). Is it possible that the MB does not detect the health of the fans and shuts down? Is there a way to fool the MB by shunting the tachometer signal on the board? Can these safety features be disabled?
2) The PS is old style ATX, which may be providing a low standby current (less than 1.5A). I disconnected the WOL plug and disabled the modem wakeup. Still no change. Perhaps the standby is just too weak.
3) The power supply may NOT be asserting the Power good signal at the correct time, causing the MB to keep the reset.
4) Interference from the graphics card.
5) And of course, I may have a bad motherboard.
I would hate to go and buy another box or power supply if I can make use of what I already have (cheap, non polluting).
Suggestions and more theories would be greatly appreciated.
