Can anyone explain why???

[Goemon]

I have an AMD 1.2Ghz with an ASUS A7V133 Motherboard running Windows 98 SE with 256MB RAM and just the other it all of a sudden the screen just went blank and the HD light came on but I couldn't do anything. I turned it off and then back on to find that my cpu fan(Dragon Orb 3) wasn't running, so I immediately shut it off. I opened the case up and checked the fan plug and it was fine. I switched it back on and as it was booting up there was an error msg "Hardware monitor dectected a fault. Check Power settings in BIOS"

So i went into BIOS setup and check the hardware monitor where it displays the VCORE voltage, +3.3, +5 and +12.

For some reason the VCORE was at 1.4 when it should be up at around 1.8 and the +5 and +12 were low and red.

The jumper settings are all default and its been working fine for around 4-6months but now all of a sudden the voltage drops and the computer is unusable after a short period of time.

If anyone can help me out I would be very grateful

well goemon, your power supply has gone dead.
check the wattage of the one in ur PC now, it should be 250-300 watts. If it's lower than this, there's your problem, too much drain on it and it's blown an unresettable fuse. If it is around 300 watts or higher, then either take it apart and check for a blown fuse, replace if necessary, or if u can't find any broken fuses, you will have to go buy a new power supply. Try for around a 350-400 this time, as it seems that you have too much power draw from it and it has had enough.

The other possible reason is you have blown a transistor or power rectifier on your mainboard. If you get a new power supply and the problem remains, then it's your mainboard... and you're up for at least $200 for a cheap one.

*(test your power supply by putting it in another PC and running a high-drain game, quake 3 or something that needs a lot of graphics grunt to run, this will test most power supplies to the limit. if it wont turn on at all, then its definantly the power supply)

*(test your mainboard in much the same way-get a few cables, connect the essentials from another PC to it and turn on. if it's still got issues, it is the mainboard)

If you eventually get a new mainboard and/or power supply and the problem still persists, well....sell the bastard.

Just as a side note...

If your mobo is fried, you could replace it with another A7V133 for as little as $77 after shipping (not $200). Alternatively while you're at it, you could upgrade the mobo to A7V266-E for as little as $125 and upgrade the RAM to DDR. Just visit Pricewatch.com for up-to-date info.

Just thought I'd shed some light on the situation in case your mobo was damaged.

Hopefully Not!!
