Crash when I install AV

Well, I still have a problem. As I said, I wiped the hard drive (format) and re-did the W7 install. As soon as I then installed Avira , and then undid it and installed Avast, the PC went into crash mode. IE, it powered off both times.. From where did you download the Avira installer? Did you download the latest version available from Avira's own web site? Same queries regarding from where you obtained Avast and its version. After uninstalling Avira (which you said already exhibited defects so that taints a subsequent AV install) and BEFORE installing another anti-virus program (Avast), did you reboot the computer? A full (cold) reboot, not a hybrid or hibernate reload. I re-did the same W7 install, and tried free AVG, and lo. it has not crashed yet after 24 hours. Task Manager says AVG is indeed running. What do you think now? FYI: AVG was acquired by Avast. https://press.avast.com/avast-closes...g-technologies |

You had all three anti-virus applications running at the same time? one at a time Okay. Then tell us which one was running when you get your crash. -- David E. Ross http://www.rossde.com/ After the 12 August tragedy in Charlottesville, Virginia, President Trump issued an evasive, equivocating statement. This is quite understandable. After all, Trump did not want to alienate his core supporters, many of whom are white supremacists. Trump's staff tried to explain away his statement and put a positive light on it, but they were merely putting lipstick on a pig. Only after pressure from his own Republican party did Trump denounce the KKK, neo-Nazis, and white supremacists as criminalson 14 August. His delay in backtracking his prior equivocation makes me doubt his sincerity. All doubt was erased when Trump appeared to backtrack again, returning to his prior equivocation on Tuesday, 15 August. |

A good, tight connection is *so* important with the parts inside the case. And moving a machine in transport can loosen those connections. The thickness of multi-layer PCBs, isn't controlled that tightly. When the press operator inspects their laminate collection, they have to pick and choose laminates, to get the correct overall dimension. On controlled impedance products, there isn't a lot of maneuvering room when it comes to thickness (each layer thickness also has to be controlled, to meet the measured electrical impedance target). A "test coupon" on the edge of a larger PCB assembly, is where a TDR is connected to measure the impedance. The test coupon is a means to accept or reject a PCB lot, for electrical performance. We had to reject one shipment of finished blanks at work, because they'd managed to go more than 10% over the specified thickness (too fat!). They can also err in the other direction, and make things too thin. Usually, a too-thin item, it's a "purposeful" error. The person making the product (blank), knows what they're doing, and they've done this when compromising on some other requirement. Fabrication requires the operator of the press, to trade all the requirements, and stay within the tolerance envelope, so the customer won't be ****ed off with them. I've seen DIMMs like that, and the surface finish and reflectivity tells me non-standard (unusual) material choices were made. Maybe the dielectric constant was quite different or something. And this is still a fiberglass and resin based product, but something is different about it. We had a local representative, who would come in, and in a two hour lecture, attempt to explain all this stuff. But it's pretty hard to cover everything the guy knows, in two hours. So he's only able to give a rough feel for the job he does. Basically, when you send him a design, that dude is adjusting *everything* :-( No aspect of the job you send him, is "untouched". Everything is translated, and fed through a $5000 piece of software, to meet the spec, rather than the actual data in the design file shipped. Very unsettling. If the plot file said to make a copper track 5 mils wide, he'd adjust it and make it 5.2 mils wide. You'd need a microscope to see these corrections. He does an ERC check to make sure no modification he's made, caused a short circuit. I had one of these twits, *erase* something they noticed in a design. Now, normally I would reward such a person with a "good catch" verbal award. Except, he didn't phone me. He didn't warn me. That there was a short circuit in the color keys... It looked like a photo-plotter error. A second company, upon receiving the design, phoned me immediately and warned me. And sure enough, I could see the plotter error. (The plotter uses a light, an aperture wheel, and "flashes" light patterns on to a photo-resist. The wrong aperture had been selected by the software.) So when you get a DIMM or a motherboard, that something is out of the ordinary, "wee willy adjuster" could've done it. I don't consider this a good engineering workflow, but what are you going to do ? They're all doing this, so you cannot punish all of them for messing around. We did actually put some of these shops on the banned list. It all depended on what sort of grief they caused. ******* The edge of the DIMM, the finish has varied from one generation to another. Ones shaped like this (seen on DDR2 and DDR3 here) | | |__| those are likely to be making poor contact because they're not actually fully seated. It's difficult to get a satisfying "click" from the latches with those. Those hurt your fingers to install, especially when the heat spreader doesn't have an area suitable for fingers to push on. So maybe one end is riding high. The older ones, the edge-card had a finish like this. This is considered "optional" in terms of a JEDEC spec. They don't have to do this. This involves more process steps, although with NC machines, it's just time on the machine. They have to mill a profile, put the keying slot on the thing, so some amount of NC is still required. The square edge in the above one, can be covered by milling the entire edge. { { { | \/ The contacts in the socket, don't have any spring action to them. (Not like the contacts in an RJ-45.) There's no compliance to them that I can see. And the finish on the top of the contact, when mixed with the squared DIMM profile (the top one), had better deflect the DIMM so it doesn't catch on a contact. That's called "connector capture" - the design has to encourage the items to mate, so they don't bind and stuff gets broken. Mechanical engineers do overall tolerance analysis, to make sure stuff like that works. It's been a long time, since I saw an actual "bend" to a contact in a memory slot. Nothing like that has happened to me recently. The bent pin (a slight bend, not a 90 degree failure like in a male IDE connector), was long enough ago, I can't even tell you what generation of RAM that was. Could have been SDRAM, or FPM/EDO or earlier, it was that long ago. I can't see how you could bend something like that, back into place. At least, if the contacts are as stiff as the modern ones are. It's bound to continue to stick out and get in the way. Paul |
