Re: Is a fan really needed?
Some supplies control the speed of their own fan to reduce acoustic noise. For at least some for of them, this goes all the way down to zero speed.
Using a supply like that would be more prudent than just clipping out the fan and hoping all is well. But if it stays cool, I doubt you have done harm.
Also, be sure you honor the minimum load requirements for the particular supply. Less load is not always better, in this case....

Re: LAN cables
Well, let me climb up the soap box and speak out of both sides of my mouth.
Side 1:
Hot connection is bad, and failure to take antistatic precautions is bad. I was a reliability guy for a very, very big semiconductor manufacturer for four years, and got to see many, many pictures of destroyed chips which died to both static discharge and other sorts of electrical events relating to end use--not our manufacture.
It was not my personal job, but the guys who had to try to persuade assembly operations to take better antistatic precautions...Leave a comment:

Re: Laptop battery...
I don't know the details, but I think the overall system design tries to protect your battery and your data by initiating shutdown _before_ the battery is actually unable to supply the load.
The difference you report is so large that I suspect that there may be a difference in the detection/response part of this process when running the two OSs on your machine.
If so, than despite its many other virtues, your machine under Linux is finishing the ruin of your battery faster, and taking worse risks with your data, compared to your...Leave a comment:

Re: Drilling out a hole?
as to where such bits come from:
Folks who fabricate PCBs use such bits by the jillion (did you ever wonder how all those holes come to be in the boards?). They discard them at a wear point which still leaves them able to drill for lesser uses. Plenty of surplus places will sell them to you in large lots for practically nothing.
Even the new ones are surprisingly cheap if you don't mind buying 50 at a time.
BUTTTTT... They are hard and brittle (need to be hard to last long enough to be useful in their original...Leave a comment:

Re: New system boot problems
The cyclic two seconds on, three seconds off condition I now believe was likely a separate issue. Most likely I got the CMOS settings to a bad state during one of the "blind boots" that are part of my main problem. The fact that resetting the CMOS made that go away is supportive, though not proof. My intended CMOS settings turn off fan warn, etc. Maybe the bogus settings I got to indeed thought I had overtemp or fan failure at two seconds and shut it off. Dismaying as that problem was, however, it is not my constant companion.

Re: New system boot problems
I'm more puzzled than ever, but currently suspect a true cold boot problem may be part of the picture.
Here is the narrative:
1. Removed PC from usage to work location--attached different keyboard, different mouse, and same monitor--no other change save on side and side panel off.
2. Reproduced previously observed two second power on followed by three second power off. Allowed to repeat several consistent cycles. Observed that the power off was almost simultaneous with turnon of the CPU fan.

Re: New system boot problems
To answer your questions:
I can't check beep code easily, as there is no case or MB speaker. Probably I should pick up on of thse $2.00 clip-on jobs for just this issue.
There are zero true IDE drives in the system, one floppy, two SATA HD's, and one SATA optical.
The case has a 120mm exhaust fan and two 92 mm front fans. For a Conroe E6600 system with a low-power graphics card, this system is extremely well ventilated--that is clearly not my problem.
The Seasonic supply is two weeks old....Leave a comment:

New system boot problems
I built a new system a bit over a week ago.
Gigabyte 965P-DS3 motherboard
Conroe E6600 processor
Arctic Cooling Freezer 7 Pro Heat Sink/Fan
Seasonic S12 430W power supply
Asus X300SE graphics card
I've loved it, but form the beginning there have been intermittent failures to boot--usually I'd just never see anything at all on the monitor, though sometimes the sequence of drive lights seemed about normal. This happened on perhaps half or a third of boots, but at worst powering off for a few minutes nearly always seemed to give me a normal... -
Re: The Great Capacitor Showdown - Rubycon vs Panasonic vs Samxon
After seeing the Solo here, and reading Williwake's and Topcat's favorable comments, I looked into it and selected it for my new PC build. I'm tired of listening to the fans on my PCs, so the provision of several quiet features (mounting on rather flexible grommets for the hard drives, and space for two 92mm front fans and one 120mm rear fan) together with a design that suited my taste better than any of the gamer-oriented radical stuff made me give it a try.
With two purchased Antec TriCool 92mms in...Leave a comment:

Re: Asus P4B533-E bad caps
Doubtless delayed a day by President's Day, my P4B533-E came back from Rolla by Priority Mail today. Despite my folly in replacing the power supply, CPU thermal grease, all three case fans, and three major data cables, my system came up apparently intact the first try. Lots of Samxon caps in place of my brown crud infested Taicon's. My three Rubycons were left in place.
One small comment on the Seasonic S12 430W--the otherwise admirably clear summary of connections is misleading in claiming 2 floppy and 6 "5.25 HDD" connections....Leave a comment:

Re: Anybody still using 800x600
A lot of laptops have widescreen monitors these days. Also if you look at larger LCD monitors (say 24 inch), I think you will find most are widescreen.
I like it for DVD watching, but that is because there is no television set in my house. I hear most people don't watch DVDs of their PC, so I don't know what drives the popularity overall....Leave a comment:

Re: Asus P4B533-E bad caps
I tried to peer through the slots of my new S12 430W which arrived today. Among the medium-small electrolytics I could see, generally the trade dress included a medium brown background with white or bright silver lettering. I don't think I can get a useful picture without breaking the warranty seal....Leave a comment:

Re: Asus P4B533-E bad caps
Your betting is good. I broke the warranty sticker and had a look. My pictures don't capture it too well, but:
1. lots of Fuhjyyu electrolytic capacitors
2. One really clear leaker, and one or two more slight trace probables
3. At least one bulge, probably one or two more
4. Perhaps more hidden under the mass of wire and other obstruction.
I've this afternoon ordered a Seasonic S12 430W supply. The 500 would perhaps have spared me a y-cable or two, and looks more future-proof, so it was a close call. My graphics...Leave a comment:

Re: Asus P4B533-E bad caps
The Antec is probably about three to four years old. The (cheap) original supply in this case died in, literally, small flash of light plus a puff of smoke coming out the fan exhaust. I hit the power switch instantly, and was much relieved a week or two later when installing this Antec that the system survived intact.
The previous supply had one component that obviously had been the smoke source. There was not enough left for me even to tell what it had been, but was axial lead, mounted horizontally on the board, quite near the main...Leave a comment:

Re: Asus P4B533-E bad caps
I fully took the system apart yesterday to pack the motherboard off to Rolla for a recap.
Lots and lots of Ost--but many seem to have RLS, not RLP mark. I even found three Rubycon. Nothing else I could recognize, though the black.bronze ones still eluded my camera capturing a useful logo.
OST and RLS markings
Rubycons-one near the 20-pin power input
and two more near the I/O panel
finally, some more pictures of the Taicon's near the CPU, both green 16V looking...Leave a comment:

Re: Asus P4B533-E bad caps
I've been slow to respond because I wanted to do extensive backing up before getting back into the box and removing enough stuff to get some answers. The box is pretty crowded, with five hard drives totalling 1.25 Terabytes.
Anyway, here is a general view of the I/O bus portion of the board after card removal.
Here is a detail picture of one type of capacitor which appears to be a major use in that portion of the board.
This smaller cap is used perhaps three time--sorry for the picture quality.

The numbers are fascinating. Which particular Maxtor drive were these systems afflicted with? My impression is that drive problems track models much more strongly than vendors.

Re: Blown cap on A8N Deluxe
I've heard that a lot of folks hot plug 1394 connections, and usually get away with it, but that there is a non-trivial severe damage rate. Not sure at all what the difference is between a "no problem" connection and one of the severe damage incidents.
Do you think it possible this board was a casualty of hot connect gone bad?...Leave a comment:
