Low Voltages - Should I Be Concerned

My positive voltages are reading a little low, but I don't know if it's enough to be concerned about. I've never really paid much attention to them before, but since I want to do some OC'ing, I'm noticing them now. I'm using a Antec TruePower 330w which came with my case. I thought it was supposed to be a good PS, but now I'm not so sure. Also, the voltage readings differ between Core Center and the bios PC Health readings. Here is what they show:
Core Center: 3.3v = 3.47 - 3.48, 5.0v = 4.87 - 4.89, 12.0v = 11.66 - 11.72
Bios: 3.3v = 3.21 - 3.25, 5.0v = 5.0 - 5.06, 12.0v = 11.68 - 12.01
The readings fluctuate between the numbers shown. Do I have power supply problem? Will I if I start to do some OC'ing of the system and video card? And finally, which readings are more accurate, the bios or Core Center? Thanks.

There will always be some fluctation even with the most powerful powersupply, depending on idle / load mode, what hardware, MoBo, what bios / software used etc etc. However the critical levels, according to the ATX std.is
11.40v min. on the 12v
4.75v min. on the 5v
3.14v on the 3,3v
In idle mode, even a bad PSU could hold the values quite good, but it´s differant under a longer period in load mode.
To find out what values you got under load, you can use speedfan ( or other alike software) , which gives you min./med./max-values on the differant lines.
Speedfan is a good alternativ to Core center for temp / voltage control.

If it´s a newer truepower 330w model, you should have 22amp on the 12v line, which should give some possibilities for OC with stability. If it´s an old model that have less then 20amp, you could be on the limit.
D/L and use 3dmark03/05 and prime95 to check stability.
https://forum-en.msi.com/index.php?topic=33850.0
OC stability is not only about a good psu, it´s also a lot of bios settings that needs to be done.
The most important ones would be mem.voltage / agp/pci lock and disable spread spectrum.
Max RAM speed depends on RAM quality, if it handles 1:1 OC or if you have to lower speed to 333mhz (5:4).
You also could add your spec./sig with what Radeon model you´ve got.

Third-party cookies: Should I be concerned that I am forced to accept in order to access a site, if I delete them after every Firefox session?

Friday 16 August, 2012
My internet service provider (https://my.gci.net/) blocks my entry to eMailGuard (a GCI spam and virus isolator) when I have third-party cookies disabled
When I allow third-party cookies I am able to access eMailGuard. I have used GCI eMailGuard and Firefox together for years and have had no such difficulty in the past.
This problem commenced 2-3 weeks ago.
I have followed all directions at http://support.mozilla.org/en-US/kb/websites-say-cookies-are-blocked-unblock-them to clear all cookies and cache, with no change. Also, my default setting (see below) is to “Clear history when Firefox closes.” If I understand correctly, clearing history will also clear cookies and cache, so I do it every time I close Firefox.
Has Firefox changed third-party cookies parameters recently? GCI of course claims this is a browser issue. Should I be concerned about third-party cookies if I delete them after every Firefox session? Any comments or thoughts are greatly appreciated.

''Keep until: I close Firefox''
That's what I use for all cookies. If you start a new session every time you start Firefox, i.e., you don't resume the same session over and over, websites cannot track you 'across sessions' using cookies; you are a new person to them during each session (unless/until you log in).
Note that "Flash cookies" need to be managed separately.
As for this particular site, if you want to spend some time research it, you could install an add-on such as Firebug or the external Fiddler2 proxy. Both will show you each request made by the browser when you load a page. Then you can see which third party sites are involved and if you like make a specific entry to allow them in the Exceptions dialog.

Strange Mobile device tried to connect to my iMac via Bluetooth! Should I be concerned?

I woke up this morning with a pop-up message saying that a mobile device tried to pair with my system but was rejected most likely from an incorrect password. I've always had "bluetooth" enabled. Never used it though, I have a wired mouse and keyboard. I never thought about possible threats occuring from this until now. I originally had all default settings turned on for bluetooth but no sharing enabled. I clicked off "discoverable" and turned bluetooth off altogether. My concern is that I am seeing a "T-Mobile myTouch Q" Smartphone in the list. I don't own this type of phone. I've never had a t-mobile phone or know anybody who does. I tried to "browse" the device but I get an error. I am unable to remove the device from my list.
It doesn't appear to be connect or ever have been connected to my knownledge but I would like it taken off.
Is there any way somebody can hack your iMac via a mobile device? I went on a researching rampage this morning but am unsure of what to think at this point. If bluetooth only operates up to 30 feet of range, who could possibly have wanted to connect at 4-5 am in the morning? Also, if they were paired, exacly what information can they gain from being paired via bluetooth to a mobile device?
Should I be concerned about this? I have Mac firewall enabled in stealth mode. Have Sophos installed and up to date and running. All sharing is turned off. What else can I do and how can I remove this device from the list so I can use bluetooth in the near future without any worries?
Thanks for any help!

Bluetooth is very limited, in range (20 to 40ft on a good day)....
The Bluetooth on my wife's iPad, before I turned it off, put out a signal much further than that. Out of curiosity, I took it down to the lobby of our building, easily a hundred feet or more--just guessing--through one floor and a number of walls. It was still getting a healthy signal there. Maybe the Mac's Bluetooth isn't so powerful. Probably depends on the device being used. I know if I move my mouse not far away from the Mac the connection is quickly lost.
That is an extraordinary connection distance for BlueTooth, did you happen to investigate the data rate at that range?
This really only applies to older Blutooth devices (so should exclude an iPad)
Many USB Bluetooth adapters or "dongles" are available, some of which also include an IrDA adapter. Older (pre-2003) Bluetooth dongles, however, have limited capabilities, offering only the Bluetooth Enumerator and a less-powerful Bluetooth Radio incarnation.[citation needed] Such devices can link computers with Bluetooth with a distance of 100 meters, but they do not offer as many services as modern adapters do.[clarification needed]
The spec for Bluetooth is a bit vague but here is some general info.
But wireless is a bit like playing Roulette

Into my download stack which appears to be a Facebook login page to someone who is not me but has my e/mail as the primary account,should I be concerned?

I have clicked on a link received in my e/mai which has put a download into my download stack which appears to be a Facebook login page to someone who is not me but has my e/mail as the primary account,should I be concerned?

I would do the following just to be safe.
Change your email password so anyone trying to use your email address won't be able to or delete that email address from where ever you got it after getting a new one.
I would trash the download.

Offset printing- should I be concerned

I'm printing a magazine and exporting it as press quality. When I do so, it says I have overset text on so and so pages. Now does this mean the printer from the place I am printing it on will not print the text that lies outside of the margins? Or what?
Is there a way around this. For example, could I convert it to a jpeg and bring it in to indesign and place it in it's position. I guess I'm thinking a printer does graphics on the page and then it goes back over it and applies the text parts. I don't understand how it is capable of printing the graphics but not the text that lies outside of the margin, if in fact that is how it works. Any help is appreciated. Thanks

For offset printing, you should be very concerned about fixing overset text.
What you see on the page with Preview mode is how it will print. If you don't see the text (and you won't see the hidden overset text), and it will not be part of your publication!
Use the Preflight panel to find and fix your overset text. If it's just a line not showing up, expand the text frame. Otherwise, you may have to change the size of the text or change your layout.

Likely not but without specific information it's impossible to say. Please download a OS X temp monitoring app and reply with actual tempratures.

My ipad air charging plug is getting hot. Should I be concerned?

My original iPad Air had to be replaced because of a hardware problem. Then my charging cord also had to be replaced. Now I am noticing that my charging plug is getting hot. Should I be concerned? Thanks. This is the plug on the end of the charging cord that came with my iPad, of course.

Make sure you are using the 10W/12W charger.
5W charger will get hot if you use it to charge the iPad.

Getting low voltage from the Macbook Pro Case

I'm getting low voltage throughout the casing whenever the brick is plugged in my 2011 macbook pro 13". I can run my fingers across the case and get the 60hz hum from the ac current. Pretty neat effect, not sure if it's totally safe or not. I tried plugging it into several outlets and changed the surge protector, with no changes happening. Anyone else getting this issue? Thank you for listening!!!
Jason

I have exactly the same problem. How did you fix it?
Is it magsafe adapter issue?

Should I be concerned with these temperatures?

While gaming on my new 13" MBP, the fans take a few minutes to respond. After about 5 minutes, I've seen temps of over 100 C on the CPU before the fans kick in. Once the fans spin up, the CPU seems to stabilize around 84 C.
It's not uncommon for me to play for 3 or 4 hours straight, should I be concerned about these temps?
edit: temperatures according to istat nano v2.2, laptop on flat surface.

to manually bump the fan speeds up when temps are getting hot, download and run this application:
http://www.eidac.de/?cat=40
It is called smcFanControl and many of the people on this forum use it. I use it on my MBPro 15" to bump my fans up just to be on the safe side.
The current version allows you to select different fan speed profiles based on whether you Mac is charging, on battery power, or on AC power.
Very usefull APP.

Mike, thanks for turning me onto that Apple Support article. My aging MacBook has been a good computer. Recently it has had a few problems which required me to erase and restore everything. I suppose I'm trying to treat it gently by doing more frequent maintenance on the disk health. I thought doing an occasional repair permissions was in keeping with a more active preventative maintenance attitude. This way of thinking may be completely wrong on my part. If you could suggest other ways to promote healthy MacBook aging I'm all ears. I think I know one way is to try to use only up to 75% of it's memory capacity, but currently I'm at about 90%.

Another device is using my IP address. Should I be concerned?

I received a message on my computer. Another device is using my IP address. Should I be concerned? What should I do to prevent this?

The error message reads: "Another device on the network is using your computer's IP address. Try connecting again later. If you continue to have problems, change the IP address of this computer or the IP address of the other device. Contact the network administrator if you need more information".
I do not have an iPad and my iPod is turned off. I DO have an Apple TV device. Could that be it?

BT Speedtest result - should I be concerned?

Hi all, bit of a doofus whith all this im afraid so a simple question for you.. Im learning tho honest! Have had intermittent and complete loss of internet connection problems for some months now. Original problem was with excessive noise on the line which was resolved with an engineer visit. Very helpful and on time too he was i should add. This was back in July, have had 2 similar issues since and having had my speed reach the giddy heights of 7/8mb Ive just run a speedcheck and its down to 4.0 again. The engineer did say that if the speed didnt stabilise then the problem may be the hub. Internet has NOT been a problem with this speed but given its dropped back to 4 and has been there for some days should i be concerned it will dip again and I'll have the same issues as before. Also have BT Vision and this sometimes has a little interference and Im wondering if this would be down to the current speed again? Its getting a bit tiresome now, dont want to give it the commentators curse but if it should become an issue again this would be the 4th time in 2 months. Is 4.0 perfectly acceptable or should I be concerned. Sorry if this is simple stuff but im not sure if this is deemed an ok rate or not given it was up to 7/8 and the engineer did say if it drops too far I'll have issues again. Just wondering if it would be the hub itself or not as the guy suggested, Ive got one of the 'old' white ones. Apologies again for not being very technical!

Hi imjolly, thanks for that. Ran the adsl Ip test.. i think.. wasnt sure how to 'navigate to adsl' after entering in browser but if ive done right downstream was 4541 and all the subsections had a green tick next to them? Ran the speedtester and this showed a download speed of 4065 and stating 1000-4000 acceptable rate of speed for my connection so I assume this is then all ok. How do you 'navigate to adsl' after entering the Ip in browser tho, not sure i did that, how do you get all the reults of noise on line etc? Cheers

Pending Charges: Should I be concerned?

Hello Folks,I've been thinking over this for about a week now. Last week, I noticed a couple of small pending charges on my Chase card. Two, from YopMail.com, were a credit and debit of $1 exactly. The other, was for something along the lines of Kalinchita.com for about 91 cents. Obviously, I have no knowledge of either of those sites, and none of the charges wound up getting confirmed.I know that in many cases, scammers will test the water with small transactions such as these before hitting with a big one. Should I be concerned about these? If so, what should I do?Thanks.

The same happened to me on my US Bank Cash Rewards card, but I check my accounts all throughout the day (I've done it since I discovered unauthorized charges some clown did in Missouri for an Onstar purchase a few years ago). Contact Chase NOW & let them know you do not know those charges.

I allowed PC Update Support to take over my computer. When they were off I checked them out and discovered they were most likely scammers. I ran my antivirus program and changed password but should I be concerned about installed malware?

I allowed PC Update Support to take over my computer (long story) When they were done I checked them out and discovered they were most likely scammers. I ran my antivirus program and changed passwords. Should I be concerned that they may have installed malware?

If you are sure they were scammers the only way to be 100% sure they left nothing behind is to wipe your system disk, do a clean install and restore from a backup you are sure was made before the scammers got onto you system.
There is no other way to be sure that thye did not leave somehting behind. In addition if you have used any credit card numbers while on the system, back account (or any other) passwords, tax returns, etc. You need to be alert fo IIdentity Theft | Consumer Information. It may be a good idea to place a fraud alert with one of the credit reporting agencies (the link above will detail what to do)
And of course change the passwords right away.
good luck

Do not enter symbol on iwork icons but can access them. Should I be concerned?

Do not enter symbols on iwork icons after getting hard drive replaced. I can access my work on all three, pages, numbers and keynote. Should I be concerned?

First, drag the iWork applications off the Dock. Then, go to Applications folder and drag them to the Dock again, so the Do not Enter icon must disappear
