my mac(2011) 13 inch running windows 10 has a weird fan. it turns on when in regular use like browsing online or word processing, having multiple windows kicks the fan on in a long but almost silent hum. at random times it is high pitched and very loud. is there something wrong?

I have a 320GB SATA drive that I was using as an external drive when, rather suddenly, the drive stopped functioning. Windows XP (which is what I was running on my old PC) didn't even recognize that I'd attached the drive. Well, I held onto the drive (it was actually under warrenty, but I couldn't get anyone to drop it in the mail for me) and not long ago someone suggested I try a program called MiniTool Power Data Recovery to see if maybe that would help with the drive. Well, I can't get it to recover any data, but …

Hello everyone! I have a server/client application running in 4 internet cafes, and i have a packet duplication problem in one of them. I have thoroughly examined my code and tested it in my lab and cannot find any bugs whatsoever. So on rare conditions some of the clients seems to receive duplicate packets. (I installed wireshark to investigate the problem in the specific shop). I am not sure if this is causing my application to crash but i have nothing else to blame! :) So the question : **Is there any chance that faulty hardware (router, switches, NICs) or …

I recently installed ubuntu 13.10 onto a desktop computer - dual boot with windows 7 - , however the system would always fail to connect to my wifi network. I decided it would be better to upgrade to 14.04 before trying to fix any problems, and at first 14.04 appeared to have the same problem. It did, however, connect on second try! But I have since only been able to connect perhaps 50-60% of the time, and often it will disconnect after some time. This is extremely frustrating, and over the last couple of days I have been wanting to …

Hello! My friend has Acer Aspire 9305WSMi laptop which does no longer boot when powered, it only gives error message with sound, which is three beeps: One longer, two short. Screen does not react a bit, attached external screen does not react at all. Harddrive does a little of work after the beeps, then the laptop does nothing. Removing battery has no effect, as well as removal of DVD-drive. I tried "nulling static charge" from the motherboard by holding the powerbutton down for >30 seconds while battery and powercord was removed, but it had no effect. I've tried to find …

Here's a fun problem for you geniuses who know SharePoint and networking. We upload videos to our SharePoint site. Regardless of the size, when we play it here at the corporate office, it will play about 20 seconds in and then reset to zero and you would have to refresh the page. If you try to download the file, it will race until 70% complete and the slow the F down and then (in Chrome) say "Failed - Network Error" and in IE it says "The [file name] download was interrupted." When downloading or watching videos outside of our network, …

I have a tale of woe to tell which is all the worse because of Microsoft's abject failure to put things right. On the first day it became available (26th Oct), I started the Windows 8 Pro download upgrade process. It's only £24.99 from here in the UK. On my first attempt, when prompted to enter payment details, I used my debit card. The response was an error message saying that the payment could not be processed and the software wouldn't go any further. So I then resorted to using my Paypal account to acquire two keys and a backup …

I asked question in [another forum](http://www.daniweb.com/hardware-and-software/pc-hardware/threads/89265/toshiba-satellite-pro-laptop-will-not-power-up-help/2) but noticed that a question above my own had not received any response within last month, so I decided to start a new thread. My Toshiba laptop yesterday shut down cold in middle of work. No lights. No sounds. No nothing. I several times unplugged it then plugged it back in but noticed that the power light would only occassionally flicker for split second; other than that ultimately nothing. I've not quite seen this question in my scan of the previous forum. Additionally, I removed battery and tried plugging it in again. Same results. …

Basically i have made a binary class that inherits from a matrix class. and aparantly when i make the binary image the deconstructor doesn't work properly. the program runs, reads in the files and makes the binary matrix. However when the binary deconstructor and matrix deconstructors are called, the program fails and shoot to this line of code. ` /* verify block type */_ASSERTE(_BLOCK_TYPE_IS_VALID(pHead->nBlockUse));` I don't know what this means even after looking online, I'm going to guess the pointer isn't being deleted, so maybe somebody could help me.

Nevertheless, after the installation, a couple of messages appear every time I initiate the computer, saying that there's a failure with "C:DOCUME~1userLOCALS~1applic~1micros~2winini~1.exe" specified in the registry. Also, even after the antivirus update and scannings, there is a message that appears 2-3 times per minute over the Symantec Endpoint Protection in the Desktop Bar, indication,saying "[SID:24142] System Infected: Trojan Download Request detected" [] .

So I'm having this weird issue, where I can do SELECT statements and INSERT statements just fine, but when I do this UPDATE statement, it sorta works. It runs without errors, and even outputs that 1 row is affected. But when I check the MySQL, nothing is updated. I've echo-ed out the UPDATE statement, which has all variables being passed to it correctly. When I take that echo-ed statement and input directly into MySQL, it works fine. I've double checked that $login_count is actually an INT Value. I've even tried converting the statement into an "INSERT ON DUPLICATE KEY UPDATE" …

Hi Whilst I have checked both the HTML and CSS for errors and have found none I have an issue with rendering using IE8 and IE7. IE9 is fine as are the other browsers. When I click on the navbar, the display loses all styling and displays for a second or less a default white background and text stretching across the full width of the display. Since my website background is a very dark shade of grey, almost black, the effect is most unpleaant. Has anyone any idea why this is happening? Geoff

We use Microsoft Online Services Sign in Tool to allow Outlook to access Microsoft's BPOS online Exhange and Sharepoint services. I recently had a user reporting that the Sign in tool was reporting "incorrect username or password" even though the credentials were correct. The solution turned out to be simply un-installing and re-installing the Sign in Tool. I hope this may be helpful to others facing the same problem.

Hi Everyone In the interest of not hijacking someone else' troubleshooting thread, I'm starting a new one, but I don't know if anyone will be able to help me at this point. Here's the situation: I passed an older HP computer "sight unseen" on to a friend to let his kids use so they wouldn't keep bugging him for his laptop. It was all "new" (three years ago!), sealed in the box and never used (the person that bought it passed away) but now that my friend is trying to set it up, it won't boot.

Ever since my team upgraded to Infragistics NetAdvantage starting with ASP.NET 2010 vol 2 from 2010 vol 1, I've been having nothing but troubles. Since there is a no backward compatibility between versions of NetAdvantage (2009 vol 1 controls cannot just be left in place if a different part of development is using 2010 vol 1, for example), you either need to get to a common version or have all the previous versions still active and in place (the former is definitely preferred). That said, I started up a fresh install having removed NetAdvantage ASP.NET 2010 vol 1 from my …

Turned it on,it posted, and I started to install windows 7 on it. About a quarter of the way into the setup (it had just started installing the OS files and such) there was a sharp high pitched humm from inside the case and I BSOD'd and it shut itself down. It now wont do anything. Every once in a while if I try turning it on the …

When I try to switch the laptop on the lamps go on and the DVD drive starts to spin..everything normal. But then after about 3 seconds it switches off before it can reach the bootscreen - like I would remove the power cable. The very weird thing is that sometimes, let's say every 1 of 15 tries the laptop starts like it should and boots up from my …

So I tried to fiddle with the hardware, while doing so I think I unplugged the harddrive because when I tried booting again it did not detect the harddrive/windows installation and I guess it tried to boot from a floppy (which I …
