Re: LG Xboom PK5 demo mode..probably

It's possible.
But it wouldn't make sense to hardwire anything. After all, why do that, when you can just take any production floor model, and program a Demo mode to activate by pressing some...

Re: Dell U2715H no power

The power supply may be good, but check the smaller power circuits near the main chip. In particular, look for linear regulators like 1117, 317, 3084, an etc., as well as integrated step-down...

Not gonna lie: that build is indeed super cool! :cool:

Re: Dell Optiplex GX110- Error 8602 and No PS/2 Controller

For a machine that has sat outside for a long time, I think the first few checks to do is see if all traces are intact on the motherboard. Contaminated water and dust can cause tracks to corrode or...

Re: Are Rubycon YXJ for SMPS or not?

Yes, Rubycon YXJ series are really good for PSU use, especially in older power supplies that don't use very low-ESR capacitors.

I've been using YXJ for about 1-2 years now in some of my PSU...

Ah, good ol' MSE: one of the first things I disable on a new OS install, along with many other things. I haven't found a need for an Anti-virus software (be it free or paid) for a long time now....

Re: CPU Fans - Which, when, and why

^ This.

I have the same exact motherboard, and indeed the BIOS has an option called "Smart Fan" that is enabled by default. This option reduces the speed of the CPU fan to reduce noise, and only...

Re: Dell Dimension 1100? ...or is it? The Ultimate Sleeper System

Oh yeah, I forgot that one. :D (But now that you linked to that thread, I do remember reading it and thinking that's one really cool project.)

Re: Club3D HD7950 (aka R9 280) 3GB strange issue

Is that with another card as the boot/main card?

If not, and you're using the 7950 as the main card, and it boots and installs drivers OK without crashing, then try it on another PC to see if you...

Re: Raidmax RX-600 ringing noise and 0ms PG

Maybe.
But now that you mention this, it is worth nothing that some of the high end PSUs out there have 10 year warranty and all kinds of bells and whistles. If they were trying to save on...

Re: Club3D HD7950 (aka R9 280) 3GB strange issue

It's dead [GPU chip], Jim.

I have numerous cards that do the same thing: PC POSTs and some of the cards even wake up the monitor on analog and digital output, but display nothing.

Re: best cheap/free scores 1.1

Yup, bad caps is likely the issue with that monitor. If I remember correctly, some of the small "startup" caps in the PSU go bad. Also a few small caps on the logic boards can cause issue with image...

Re: Dell model L275E-01 pn: Wu142. Optiplex 755 small form factor.

That's not how it works.
If the PSU is not turning Off after turning On, first try using it on a different motherboard/PC to make sure there isn't something with the settings on the PC you are...

Re: best cheap/free scores 1.1

Don't assume the battery is good just because the CMOS date/time is correct.
I've seen it before (and in fact have one PC in the closet like this with a dying CR2032 battery) where the motherboard...

Re: Monoprice Hybrid Amp 13194 may need caps

Can never know if any of those Chong caps are bad or not (well, they always are! :tongue: ) just by looking at them.

Either take out of circuit and check ESR and capacitance or replace them...

Re: Cheap gaming computer with Intel 975 chipset

Just curious, what video card are you using?

20-30 frames per second is not really great, though enough for non-competitive gaming.

I'd look on YouTube for videos with similar PC setups to see...

Re: best cheap/free scores 1.1

Yup, seems likely to be a RAM issue.
I would do a full removal and re-insertion of the RAM. If you have any known good SDRAM of your own, try that instead. The RAM that came with this computer could...

Re: Dell model L275E-01 pn: Wu142. Optiplex 755 small form factor.

Not exactly, but close.

The thermistor doesn't give a "low voltage" to the standby circuit. It simply acts as a high series resistance device when the PSU is first plugged in, so that the...

Re: Dell model L275E-01 pn: Wu142. Optiplex 755 small form factor.

I don't have an exact part number for you, but SCK 054 is a very commonly used NTC thermistor for power supplies, so you can try that first, at least as a test. (Generally, most cheapo gutless PSUs...

Re: Post your system.......

Unfortunately, not that motherboard - an ASUS P5GC-MX (i945 chipset). It can only do 800 MHz FSB. That's not an issue, though, as I do have several other Dell boxes with 800 MHz FSB C2D CPUs that are...
