Built a system using an Athlon 3200+ 400fsb and a GA 7VT600 1394 mobo.VIA
600 chipset. Had a lot of reboot problems.
When?
Doing what exactly?
What operating system?
If win2k or XP, disable the reboot-on-error feature and note
bluescreen info if applicable.
Was told the VIA wasn't to good
with my CPU
Whoever told you that is just plain wrong.
Nothing wrong with KT600 but there are a few minor
difference:
1) No dual channel memory - not important without
integrated video, only 1-2% performance loss if that.
2) PCI bus implementation not as good, if you had several
(2 or more) high bandwidth PCI devices you might need tweak
latency settings per each. For example, a PCI video card,
PCI Gigabit NIC, PCI RAID controller and fussy sound card
all together may result in one or more exhibiting
sub-optimal performance. That's also true of nForce2, the
aforementioned is pushing PCI bus limits to begin with but
moreso for Via than nVidia chipsets. Via does not however
still have the infamous PCI issues to the extent of data
loss when combined with certain soundblaster cards, that was
several southbridges ago.
3) No PCI or AGP lock - Overclockers might lose a minor bit
of FSB increase, but overclocking past 200MHz/DDR400, the
dividers are high enough that it's not so significant a
problem as some would us believe... should still get up to
220/DDR440 unless there are other limitations unrelated to
the chipset and dividers.
A simple "Via therefore reboot" or any extension of this
argument is simply not true. At worst some setups will have
a 4% lower performance or need latency adjustments. It is
offset by lower prices most often, as with any other choice
the user picks a minor performance increase for slight price
increase or not... though today that pricing is going in odd
directions due to it being aged/retired technology.
... so I switched to a GA 7N400 Pro2 ver.2 (NVidia ULTRA 200) and
it's been fine for about 2 weeks. The CPU was an OEM not retail. Last night
I hooked my digital camera into a USB slot and the computer froze.
Front case USB which (may or may not) be pin-comatible with
the motherboard, ie - wired correctly at the connector, OR a
port on the rear of the board itself?
Had to
power down at the PSU.
What does this mean?
You had to flip PSU switch or pull the plug?
What power supply make/model/rating/etc?
Is your motherboard jumpered to use 5V or 5VSB (consult
manual) for USB and PS/2 ports?
Does the power supply have a rated (labeled) or real
(name-brand PSU so we can trust the label) 5VSB current
rating high enough for all the USB and PS2 devices which
might be jumpered as powered from 5VSB?
Now it won't post at all. Blank screen. Tried
different v-cards, monitors Etc. nothing. All fans run fine and it kind of
grunts like it's trying to boot but nothing. Can't get into the bios at all.
No beeps at all. If I leave it on for an hour the CPU, chipset HS etc. are
not even warm. Any ideas? PS Quadro FX 500 V-card.
Try clearing CMOS with AC cord disconnected, then reconnect
AC & power-on system.
If you have a spare PSU lying around (of sufficient
capacity) try that too. Take voltage readings at
motherboard connector(s) with a multimeter if possible.
If you have the ability to trace the USB port circuit on the
board and test continuity of the fuse that might be
revealing too... if it has a fuse, Gigabyte boards usually
do. Also compare the USB pinout to spec, that 5V, data-,
data+, and GND (or at least 5V & GND) are on correct USB
socket pins.
Can we assume this USB camera had been working, connected to
another system sucessfully to the extent that we can rule it
out as a suspect?
