The manual doesn't tell you much, does it.


The DDR3L should work, but it''ll likely run a bit hotter since it's going to run at 1.5V. The motherboard will force it to go to 1.5 and it will. 3L can do that.

Yeah, that's what I was afraid of. It's a nice computer, but it runs hot. I was hoping to improve that as well.

Thank you.

Let's say I've a PC with two hard drives, each HD with a different operating system (win7, win10). Is there a way to set up dual boot without having to reinstall either?

Yes.

Either one will support booting the other from their appropriate BCD.


https://technet.microsoft.com/en-us/ff541231(v=vs.96)

You would just add a BCD entry for which-ever drive you choose to be the secondary one, on the primary one.


EG, if the win10 disk is the primary, you would edit the win10 deployment's BCD with BCDedit (or one of the GUI utilities out there) to add the other drive as a bootable medium with an entry.  It would then show up in ntldr's menu with a countdown.

Thanks, that might work, once I learn how to use it. Continuing my adventures with this particular system - I've a broadband connection on the computer. I need to configure it on the Win 10 partition (because I carelessly deleted the connection to stop updates while I'm setting up the dual boot). The owner does not know login&pass. The Win 7 partition has the connection working, the Win 10 one doesn't. Is it possible to read the login&pass somewhere from Win7 level?
The interwebz apparently only know about wifi, not broadband.

Too vague.

login/pass for the wireless lan connection?

If so, YES--

If you mean "Active Directory username and password"
I'll have to look into that.

No, not the wifi connection. That one I know.
There's a wifi modem, but the PC is ancient and doesn't have a wifi adapter, so the connection goes through a cable. When you try to set up a new broadband connection in Win 10, you're asked for the l&p. That's what I need to extract from the Win 7 system.

I am still confused.

Which of these is the case?

1) I need the local windows system administrator password

2) I need a connected network appliance's username and password


I have a solution for the first option. It's called the Offline Windows Password & Registry Editor.  You just promote your limited user to a local admin with it, and bob's your uncle.
https://pogostick.net/~pnh/ntpasswd/

Promotion in this manner works very simply-- It adds the limited user to the administrators group, which magically gives it full admin powers, even if you do not know the password for the actual local admin account. This makes it pretty safe to use for such promotion.  It *ALSO* has the power to strip a user account of its password.  Since passwords are stored encrypted in the SAM database, the tool cannot just tell you what the password is if one is set. It CAN delete the password though. Doing so has potential harmful effects if there are encrypted files, because the password is used in the encryption algo, and if you blank it, then files will no longer decrypt.  If you just need to get around the "naughty naughty, you are not an admin!" nag, then promoting your limited user temporarily will get your foot in the door, and you can do what you need and get out. (Run the tool again and de-promote, OR-- while being admin, go to the user-accounts control panel applet, and depromote it back to limited user again. Easy peasy.)


For the latter...

Two possibilities. One more sensible, the other less so.

1) Use the system that remembers what this is to log into the appliance, then SET A NEW PASSWORD.  Write it down. Tape it under the lid of the system chassis for the next monkey. It is likely to be you again. Save yourself the grief.

2)  Try to extract the credentials from the browser.

This probably counts more as "shopping" advice than computer advice, but should I wait a month for Black Friday/Cyber Monday deals before purchasing a new graphics card? There's a few other parts I intend to get, but the graphics card is the most expensive of the lot yet the one most needed. I have no idea what, if any, kind of deal to expect. A 20%-off deal might be worth it, but I probably won't want to wait if the discount is less.

I still have a cyber monday ad from last year. A card advertised then at $499 (US) is the same configuration and core as one that's selling for $599 now - and it isn't top-of-the-line in the midrange category anymore. There's no guarantees, but I'd suggest waiting since you're only a little over a month out. Alternatively, if you live near the right kind of store, you might be able to get a good enough price to justify not waiting.



As an aside, DO NOT EVEN CONSIDER buying a used video card. Any card that was used for cryptomining is going to be essentially burned out (as this puts massive strain on the card), and that's where a ton of the used cards on the market come from.

Black Friday deals are not deals. Find another time in the year to find things on sale.

Correct. I've seen prices that are higher "on sale" for Black Friday than normal.


If you're buying fairly high-end, wait until a new "the best" card comes out like people do with buying cars that just became last year's model. Mid-range, I'm not sure if the prices change much, I've not bothered following them long enough to find out.

I usually use the newegg power search to find the one I want, then go find a different website to sell it to me. If you don't know what one of the questions means, just leave it blank. I would start the search with condition: new only, because second-hand electronics have high odds of not working for long/at all. Also, you probably want to read some reviews, to see if the common problems are something you care about or not.

This is almost certainly unanswerable, but worth a shot.



I've been having a problem lately (Windows 10, over the last two dozen patches or so) where I click through the topmost window. For example, I might be trying to drag an Explorer window to my secondary monitor, only to grab and drag a Chrome tab instead, or try to edit a cell in Excel and wind up typing the value in the middle of a Notepad sentence. This happens with maximized windows, and in the middle of windows, so it isn't likely to be a case of misjudging the boundaries.

That's a weird problem. Maybe start by turning off all Visual Effects, see if anything is different.

Right-click on a "This PC" or "My Computer" thingy, select Properties, the Advanced tab, then in Performance, then Visual Effects, and Adjust For Best Performance. You may want to turn back on "Smooth Edges of Screen Fonts" however.

I got a new laptop BTW and Windows 10 was sluggish as hell on it. Doing this tip actually made it feel zippy.

What exactly would happen if I uninstalled "Update for Windows 10 for x64-based systems"? would that break my computer or would it just stop trying to update?

That's a particular update, it's not the "update service". It's a generic name for an update package, and it'll have a serial number which you can google to find out what's in the bundle.
