CPU problem

I should've writtten, "since i've not heard of that brand it
would seem unlikely to be a decent make". I cannot be certain
that it's the problem and suggest taking voltage readings with a
multimeter. If you had a better spare PSU it would be a useful
test to swap them. Motherboard is known to run that CPU, video
card is known to work, all that's left (since you could strip
system down to just essentials) are memory, PSU, and CPU. Odds
are low the CPU is bad, and if new memory tests OK with old CPU
in system, that seems unlikely too. PSU is most likely suspect
even without knowing it's origin.

Oh how would I check the voltage from the PSU if I had a DMM?

Thanks,

Umm, ok. There are several black, red and orange wires in my motherboard
connector though.
 
Thank you. I've just gotta plug it into the mains and then do it, right
(my PSU doesn't have an on-off switch on the back)? Black lead from DMM
into black on the motherboard connector?

It should be installed in system and plugged into motherboard,
then AC plugged in. System should be turned on normally, left
"on" even if it isn't POSTing. Multimeter probes are to be
inserted in though back of ATX connector, and about 6mm down will
contact the back of the metal insert. The lazy way to check +5V
& +12V would be to do so at a drive connector instead of the
motherboard connector, but be sure to check 3.3V reading on the
motherboard connector.

Black lead from DMM to a black wire on motherboard connector, or
a drive lead, or case... anything grounded should suffice but
technically the motherboard connector is the correct way to do
it.
 
Hi, I got a new Athlon XP 2500+ Barton and installed it with its
heatsink/fan. When I booted my machine, I didn't see a POST screen and
the light on the monitor just kept flickering on and off. My memory was
266Mhz PC2100 and my motherboard (ASUS A7V8X-X) says it only supports
333Mhz RAM with a 333Mhz FSB CPU, so I bought some 333Mhz PC2700 RAM but
still had the same problem. Now, I've tried with my old memory and my
old CPU (Duron 800Mhz) and still no POST screen :(. Can anyone help?

Thanks,

Nick Chorley

What Kony said.

You need a larger power supply.

Good luck.



Have a nice week...

Are you 100% sure? Would a 350W one do?

Does your mobo have a place for a square, four-pin plug near the CPU? Does
your PSU have said plug and is it inserted? That provides power to the CPU
and most boards that have the socket won't run without the cable plugged in.

Of what? Of my opinion? Yup...100% sure. lol

I (and others here) do the best we can to help...with the limited info
we often have. This kind of help is only meant to provide some
clues...some ideas. Its then yer job to interpret the
information...and discard what you think won't work.

The solutions we provide are only worth what you've paid us for them!

Possibly? But why would you want to purchase something that is
already on the way to obsolescence?

Good luck.

No, it doesn't. I've used the board before..

Can't afford to get a higher wattage PSU, they're expensive.

Don't mention it.

In that case it's drawing a lot of current from the 5v rail, well over 100
watts, you need a good power supply for that, one that is weighted towards
the 5v rail rather than the 12v rail as most modern ones are. To get that
sort of current stably from the 5v rail you may have to get a modern PSU
rated as high as 500 watts or more. Check some PSU specs, you may find one
with high 5v witha lower overall wattage/price.

What BIOS revision are you running? Version 1012 is the latest, released two
weeks ago.

Decent modern mobos have the four-pin 12v plug I mentioned earlier to power
the CPU from, and modern PSUs have the voltages weighted towards the 12v
rail. (Some to the extent of having dual 12v rails to provide clean power
for the CPU when a drive spins up).

Other than that, all I can say is you have a VIA chipset board, you get what
you pay for.

I'm not sure what BIOS revision I'm running. I'd have to reinstall my
Duron and check, not got too much time right now. The PSU I ordered was
this:

What's wrong with VIA chipsets? Both the boards I've had have used them
and I've not had problems.

Thanks,

On second thoughts, screw it. I'll stick with the Duron cos this is
causing me too many problems.

Than what do you call what's going on now? :-)

Seriously though, many will argue but, from personal experience and maybe
bad luck, I've had a lot of trouble with VIA chipset boards in comparison to
other boards. Enough so that I wouldn't buy another one.

Well I didn't think it was a mobo problem :(.

Are nForce chipsets good then? I'll always stick with AMD CPUs in my
machine, dunno why, just don't like Intel much.

Thanks,
