Windows 7 professional Driver Issues I am using an Intel board made in 2009, model  P5KPLAM-IN series but today I've upgraded it to a DDR4 supported Mother manufactured by ASUS with Intel I3 7th generation and I deployed the same hard disk and I don't have old motherboard for some reason.  Nnow whenever I boot up the old HDD in the new motherboard Windows 7 booting logo starts loading but before fully loaded on screen  Windows 7 reboots automatically.  I tried booting with Windows7 bootable DVD but mouse doesn't works at Windows 7 installation GUI, I also tried loading driver from USB and rescan drivers but nothing happens, Windows don't find drivers in it.  I connected the hard disk to another running pc with Windows7 it shows a single 470GB c: drive .  If somehow I load ASUS motherboard drivers in the attached HDD then I hope everything starts work normal.
Can Windows 7 be repaired to run with new motherboard? I have HP computer and it came with Windows Vista. It also had an option to upgrade to Windows 7 via upgrade disc. I have upgraded to Windows 7 via the special upgrade disc (It is special because it will only allow to install Windows 7 if Vista is already installed.  My motherboard recently died. I just replaced it and Windows 7 will not start up. It reboots and sometimes gives a blue screen of death. Very similar problem as described in this post: . Windows will not boot into normal or safe mode. Start up repair from system repair disc does not fix the problem. However, "" post on superuser describes that it should be possible to run Windows 7 on a new motherboard.  Is it hopeless to find a way to repair Windows 7 and I need to do a clean install? Is there a difference for repair options between OEM and retail versions of Windows 7? I remember doing this type of repair just fine in Windows XP days, so why am I unable to do so with Windows 7 - is it Microsoft or HP's fault? Should I stop buying HP computers or should I switch to Ubuntu?
How many bandits must agree? Problem  A group of $n~(1 \leq n \leq 30)$ bandits hid their stolen treasure in a room.  The treasure needs to be locked away.  The bandits want to ensure that at least $k~(1 \leq k \leq n)$ of the bandits must agree in order to retrieve the treasure.  They have decided to place multiple locks on the door such that the door can be opened if and only if all the locks are opened.  Each lock may have up to n keys, distributed to a subset of the bandits.  A group of bandits can open a particular lock if and only if someone in the group has a key to that lock.  Given $n$ and $k$, how many locks are needed such that if the keys to the locks are distributed to the bandits properly, then every group of bandits of at least size $n$ can open all the locks, and no smaller group of bandits can open all the locks?  For example, if $n=3$ and $k=2$, only 3 locks are needed - keys to lock 1 can be given to bandits 1 and 2, keys to lock 2 can be given to bandits 1 and 3, and keys to lock 3 can be given to bandits 2 and 3.  No single bandit can open all the locks, but any group of 2 bandits can open all the locks.  My thoughts  At first glance, I thought it was just a simple combinations problem ($nCr$), and the provided test cases confirmed my suspicions: when $n=3$ and $k=2$, $\binom{3}{2}=3$.  Likewise, when $n=5$ and $k=3$, $\binom{5}{3}=10$.  However, two cases where this doesn't work are where $n=2$ and $k=1$ and $n=5$, $k=4$ (it gives $2$ and $5$, respectively, when the correct answer according to the judging data should be $1$ and $10$).  Next, I bothered a colleague who's a math major, and he briefly glanced at it and suggested it might be a hypergeometric distribution problem.  However, if this is correct, I'm having trouble wrapping my head around it - all the examples I can find have 2 distinct categories, e.g. red and green marbles being drawn from an urn, and I don't see that here.  An example in the terms of this problem would be extremely helpful.  If this isn't correct, where do I go from here?  I've been spinning my wheels on it for quite a while.  Background  This is for homework for a CS class (I'm a CS major with 2 semesters of calc plus discrete).  I'd like to be able to understand the math behind it, because once I can understand it, I can program it.  This problem originally came from an ACM ICPC regional contest this year, but my professor has made it into a challenge homework problem. I've begun cooking Asian food in the past year or so, and in many Korean and Chinese beef recipes, I see instructions to soak beef in water. Just plain water, not salt water or anything. And every recipe seems to have a different  time - from 5 minutes to like, multiple hours.  I inquired about this and was given various reasons for this step, including "to remove the blood (because it is simply undesirable", "To remove the blood, because it gives the meat a bad taste" or "To soften the beef".  I'm wondering:   Does soaking meat in water really remove that much blood? How much of a flavor component is blood and why would it give it a bad taste (especially since i've never soaked beef before and I've like the taste just fine)? What is the action of solute-free water on a piece of beef immersed in it? Can it really tenderise it to any degree, or is there any osmosis occurring or other such physical/chemical action? Evalute $ \lim_{n\rightarrow \infty}\sum^{n}_{k=0}\frac{\binom{n}{k}}{n^k(k+3)} $ Evaluate $\displaystyle \lim_{n\rightarrow \infty}\sum^{n}_{k=0}\frac{\binom{n}{k}}{n^k(k+3)}$.   $\bf{My\; Try::}$ Although we can solve it by converting into definite Integration.  But I want to solve it without Using Integration.  So $\displaystyle \lim_{n\rightarrow \infty}\sum^{n}_{k=0}\frac{\binom{n}{k}}{n^k(k+3)} = \lim_{n\rightarrow \infty}\sum^{n}_{k=0}\frac{(n-1)(n-2).......(n-k+1)}{k!\cdot n^{k}\cdot (k+3)}$  Now How can i solve after that, Help required, Thanks Is it possible to find all php files within a certain directory that have been modified on a certain date  I'm using   find /var/www/html/dir/ -mtime -28 | grep '\.php'    to get files modified within the last 28 days, but I only need files that have been modified on the following date: 2011-02-08 Global variables in AngularJS I bought a new MacBook Air and was able to connect to the internet at first but now it won't connect.  I have other devices as well as other computers on wifi but my Mac won't connect.  When I try and click on the wifi, it tells me that it can't be joined.  How can I troubleshoot? The app forgets that I voted when I scroll the question How do I get money back for my foreign coins? Tonight I just cleaned my room and while doing this I found some money. I counted it and I found out that there are a lot of coins from 25 different countries.  I know that normally banks don't exchange foreign currencies in coins, but is there a way so that I can still get some money for my foreign coins? Deployment error regarding translations when generating package version Сanonical form of a quadratic form by Lagrange's method This is just an eg. to understand how to solve it.  There is a quadratic form as below we need to bring to canonical form using Lagrange's method and find the coordinate transformation.   Then find the positive &amp; negative indexes, rank of the quadratic form. Finnally, to investigate sign-definiteness of the quadratic form by two ways: according to it's canonical form and the criterion of Sylvester: $4x_{1}^2+2x_{2}^2+10x_{3}^2-4x_{1}x_{2}-12x_{1}x_{3}-8x_{2}x_{3}$  Any clarification on how to do it are very welcomed. When a body lies on the surface of the Earth it is under the influence of gravity. The force on the body due to gravity causes it to exert a force on the ground and the normal reaction acts in the opposite direction causing the resultant force on the body to be zero.  However, how can the body exert a force on the ground when it does not have any acceleration? Since force equals mass times acceleration how does a body without acceleration experience a force? Number of ancestors 750 years ago I have 2 ancestors, a father and a mother. Two generations back - 4 ancestors. Three generations back - 8 ancestors.  30 generations back: 2^n = 2^30 = ~1,000,000,000 ancestors.  If a generation is 25 years long, 30 generations are 750 years and 30 generations ago the year was 1,267. But the world population was only 400,000,000 people so how can my math be wrong? and is there a way to estimate the number of ancestors I had 750 years ago? Pluralizing abbreviations where the noun is not the last word It is well known that confidence intervals and testing statistical hypothesis are strongly related. My questions is focused on comparison of means for two groups based on a numerical variable. Let's assume that such hypothesis is tested using t-test. On the other side, one can compute confidence intervals for means of both groups. Is there any relation between overlapping of confidence intervals and the rejection of the null hypothesis that means are equal (in favor of the alternative that means differ - two-sided test)? For example, a test could reject the null hypothesis iff the confidence intervals do not overlap. How to set up USB for Virtualbox? Copy files from Network Mapped Drive I am trying to copy a file over from a mapped drive on a network to the current computer through a batch file.   I've already attempted the following below and still no results. The plan is to run a batch file to copy a file from a network drive down to the local C:\ drive.   @echo off copy H:\Videos\TargetVideo\TargetVideo.mp4 C:\Video\ How can I list all user names and/or home directories? I want to list all the users dirs on the machine.Usually, I will do:  ls -l /home   But I use it in a script that will be deployed on others machines and maybe on that machines they don't call it home (e.g. myHome). So I want to generalize it to ls -l ~. But it just lists my users home dirs instead of all users home dirs name (basically I want to get a list of the users names on the machine). How can I generalize it? A sci-fi book or TV show about a tribesman discovering he or she actually lives in a huge spaceship Inner Product on $\mathbb{R}$ and on $\mathbb{C}$ This is a question of the book Linear Algebra of Kenneth Hoffman.  Describe explicitly all inner products on $\mathbb{R}$ and on $\mathbb{C}$.  I think that if $&lt;,&gt;$ is one inner product on $\mathbb{R}$ (or $\mathbb{C}$) then $&lt; ,&gt;=K[,]$, where $[,]$ is the standard inner product. Is that correct? I have complicated math expression:    Vertical spacing between text and fraction line is too small. I tried to define new \frac command (with amsmath package) with adjustable vertical spaces.
