  • Constant crashes in windows 7 64bit when playing games

    - by yx.
    I've tried everything I can possibly think of in trying to fix this problem and I'm totally out of ideas, so any help would be appreciated: The problem: whenever I fire up a game, it works for a short while with no problems and then it would crash. Either its a hard crash, forcing me to reboot, or windows would report that the display driver has stopped working and recovered. Here is a list of things I've already tried: Drivers - tried the latest drivers (catalyst 9.12) as well as the stock drivers that came with the video card. Also have the latest BIOS/chipset Memtest - Ran Memtest86+ overnight, had no problems, the windows diagnostic tool also does not find any problems. Overheating - Video card/cpu temperatures are well below peak (42 and 31 Celsius receptively) PSU Voltage - CPUID shows that the voltage levels are all above what they should be. The PSU itself is only roughly 16 months old and is a good model. HDD - No errors when checked GPU - Brand new (replaced previous card since I thought it was the problem, apparently not) Overclocking - Everything is at stock levels, memory voltage is set to manufacturer's standard Specs: Motherboard: ASUS P5Q Pro CPU: Core 2 Duo E8400 3.0 ghz OS: Windows 7 home premium 64 bit Memory: Mushkin Enhanced 4GB DDR2 GPU: Sapphire HD 5850 1GB PSU: SeaSonic M12 600W ATX12V DirectX: DX11 Event Viewer after a crash always has these logged: A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 1 The details view of this entry contains further information. A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 0 The details view of this entry contains further information. A previous card that I had (4850x2) also had these errors, so I changed video cards, but the same thing is happening.

  • Unexpected behaviour in a Lotus Notes programmable table

    - by Mark B
    I'm designing a workflow database in Lotus Notes 6.0.3 (soon upgrading to 8.5), and my OS is Windows XP. I have recently tried converting a tabbed table into a programmable one. This was so that I could control which tab was displayed to the user when it was opened, so that they were presented with the most appropriate one for that document's progress through the workflow. That part of it works! One of the tabs features a radio button that controls visibility of the next tab, and a pair of cascading dialogue boxes. One contains the static list "Person":"Team", and the other has a formula based on the first: view:=@If(PeerReview = "Team"; "GroupNames"; "GroupMembers"); @Unique(@DbColumn(""; ""; view; 1)) The dialogue boxes have the property "Refresh fields on keyword change" selected. The behaviour that I wasn't expecting is this. If the radio button is set to "Yes" and a value is selected in one of the dialogue boxes, the table opens the next tab. If the radio button is set to "No" and a value is selected in one of the dialogue boxes, the entire table is hidden. I can duplicate the latter by switching off the "Refresh fields on keyword change" property on the dialogue boxes and instead pressing F9 after selecting a value. I have no idea why the former occurs, though. The table is called "RFCInfo", and I have a field on the form called "$RFCInfo" which is editable, hidden from all users who aren't me and initially set by a Postopen script, which I can post if necessary - it's essentially a Select Case statement that looks at a particular item value and returns the name of the table row relating to that value. Can anyone offer any pointers?

  • What desktop boards support VT-D or IOMMU?

    - by Jeff Shattock
    I'm looking for a desktop board that supports either VT-D (Intel) or IOMMU (AMD) technology. This is the IO virtualization technology, not VT-x for CPU virtualization. I've found a list of chipsets that are purported to have this, but every board I look at, the vendor has decided to not support that feature. I would really prefer a desktop board over a server board for this. Does anyone have a specific model that is known to support this technology?

  • When and how often to start connection to database in php?

    - by AndHeiberg
    When and how often is it good practice to start the connection to your database in php? I'm new to databases, and I'm wondering when I should start by database connection. I'm creating a api with an index, controllers and model. Should I start the connection in the index and then pass it to all the other files, start the connection at the top of all files and call it as a global in functions as needed or start and end the connection in every function?

  • RAM upgrade, what options are suitable?

    - by user55150
    I have a Dell GX520 optiplex model (mini tower), and I want to upgrade its RAM. I currently have 1GB RAM and I want to upgrade to 2GB. All I know about RAM is its capacity, and I've heard about speeds lately like 400mhz, 533mhz, 800mhz, 1333mhz. I want to know what are the differences among them and can my PC support all those types of speeds or not? And what is the most suitable one for my Dell PC, to avoid any problems or limitations.

  • Any free Exchange hosts out there?

    - by Pure.Krome
    Hi folks, Are there any free Microsoft Exchange hosted solutions? I understand that Microsoft Exchange is a paid/licensed product, but I was curious if there might be a host that has a free hosting model (e.g. for <= 3 mailboxes per domain)? Larger mail boxes per domain == cost. ?? Finally, please refrain from suggesting other mail services (eg. sendmail, etc).

  • Firewall/Router upgrade

    - by Atlas
    We've been using a SonicWall TZ170 for several years, it's been working fine with occasional glitches. Now we switched to a 100Mpbs broadband, and the firewall has become the bottleneck for internet access because its max throughput is around 20-30Mpbs. Any ideas for a replacement? Brand/Model?

  • What apps can you only get on Mac and not Windows?

    - by ytk
    What apps do you absolutely have to use a Mac to run, and there are no decent Windows PC equivalent? This is not a religious war. Please be specific and practical It doesn't have to be a direct 1-2-1 comparison, but overall usefulness to the task I'll start off with a few: KeyNote -- the animations are quite cool and not available in PowerPoint iTune's photo sync -- on Windows it makes copy of all the photos you want to sync, effectively double the space taken up by your photos. On a Mac it's easier as long as you use iPhoto Keychain -- a centralized password manager tied to the OS. The benefit of this is you don't have to set a Master Password (like Firefox) which you need to enter when starting the browser. And it doesn't reveal your password (like Chrome, which makes no effort in hiding the password you have stored in Options) Time Machine -- 0-configuration backup in the background. Easy interface for restoring a file, or even just a contact in the address book. Text-to-speech -- works in any program, and sounds better than Windows computer voice Quick View -- press space bar to preview a file. Windows95 had quick view, but was removed.

  • Music player for Linux which remembers the playback position

    - by pts
    I'm looking for a music player for my Ubuntu Karmic desktop. I need the following features: supports multiple playlists remembers the playback position (file and time) for each playlist preferably, remembers playback position even when the process is killed lets the user adjust playback speed, without changing the pitch I don't care if it's a GUI or command-line player or it uses a client-server model. I've tried Rhythmbox, which doesn't have features 2., 3. and 4. Which player would you recommend?

  • Monitor programs accessing my keyboard?

    - by Anti Earth
    As of a few days ago, my computer is behaving 'erratically'. When I am typing, my pointer will randomly move to another place in the text and start typing a semi-random string of characters. ("gvyfn" is common; It has typed this about 8 times whilst I composed all the text above) It often highlights part of or all the text and overwrites it. It sometimes goes into loops of pressing Control-alt-delete down, bringing up Windows 7 menu thing. It sometimes even messes with mouseclicks; they have unexpected results, like requesting admin priveledges from applications, instead of switching to their window. I believe this is because it is holding a alt-function key down. This behaviour happens periodically, in waves. It might subside for an hour, then continue to haunt me. I believe it to be a virus or malicious program. My anti-virus (Symantec) and multiply MS rootkit removers could not find anything suspicious. I've noticed that sometimes it re-maps keys, and types gibberish when I press certain keys (though no pattern is evident). I believe a malicious program has installed a keyhook on my computer. I'm wondering... - Is there a way to let me view which programs are emulating keystrokes? - Is there a way to view what keyboard hooks are installed? (I'm also at liberty to try any other techniques to remove this blasted thing. It is easily the most fustrating computer problem I've encountered). Thanks!

    - by dom
    My gateway laptop model nx570xl originally rebooted normally. I don't know when it happened, but now when i try to reboot it Keeps trying but it never happens forcing me to shut down and wait a random amt of time before it will start up again. Its very annoying and wastes a lot of my time. I don't think its a cpu overheating problem because its random when it starts up after i turn it back on. Any ideas?

  • Series of abstract classes and NHibernate

    - by Chris Cowdery-Corvan
    Hello, and first off thanks for your time to look at this. For a research project I'm working on, I have a somewhat complex design (which I've been given) to persist to a database via NHibernate. Here's an example of the class hierarchy: TransitStrategy, TransportationCompany and TransportationLocation are all abstract classes. The XML configuration I have is presently: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Vacationizer"

    Hey! So I'm trying to code something on wordpress for the first time but the validator doesn't seem to like me. Look at the error I got while validating: Line 87, Column 33: document type does not allow element "li" here; missing one of "ul", "ol", "menu", "dir" start-tag I've searched everywhere, I'm not aware of any missing or misplaced li or ul tags can someone help me out on this one? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head profile="http://gmpg.org/xfn/11"> <title> Blog</title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta name="generator" content="WordPress 2.9.2" /> <!-- leave this for stats please --> <link rel="stylesheet" href="http://localhost/wordpress/wp-content/themes/cmc-milagro/style.css" type="text/css" media="screen" /> <link rel="alternate" type="application/rss+xml" title="RSS 2.0" href="http://localhost/wordpress/?feed=rss2" /> <link rel="alternate" type="text/xml" title="RSS .92" href="http://localhost/wordpress/?feed=rss" /> <link rel="alternate" type="application/atom+xml" title="Atom 0.3" href="http://localhost/wordpress/?feed=atom" /> <link rel="pingback" href="http://localhost/wordpress/xmlrpc.php" /> <link rel='archives' title='March 2010' href='http://localhost/wordpress/?m=201003' /> <link rel="EditURI" type="application/rsd+xml" title="RSD" href="http://localhost/wordpress/xmlrpc.php?rsd" /> <link rel="wlwmanifest" type="application/wlwmanifest+xml" href="http://localhost/wordpress/wp-includes/wlwmanifest.xml" /> <link rel='index' title='Blog' href='http://localhost/wordpress' /> <meta name="generator" content="WordPress 2.9.2" /> </head> <body> <div> <h1><a href="http://localhost/wordpress"> Blog</a> </h1> Just another WordPress weblog</div> <div id="container"> <h2><a href="http://localhost/wordpress/?p=8"> Teste Post 3 </a></h2> <div class="post" id="post-8"> <div class="entry"> <p>Aliquam erat volutpat.

  • JPA entities -- org.hibernate.TypeMismatchException

    - by shane lee
    Environment: JDK 1.6, JEE5 Hibernate Core 3.3.1.GA, Hibernate Annotations 3.4.0.GA DB:Informix Used reverse engineering to create my persistence entities from db schema [NB:This is a schema in work i cannot change] Getting exception when selecting list of basic_auth_accounts org.hibernate.TypeMismatchException: Provided id of the wrong type for class ebusiness.weblogic.model.UserAccounts. Expected: class ebusiness.weblogic.model.UserAccountsId, got class ebusiness.weblogic.model.BasicAuthAccountsId Both basic_auth_accounts and user_accounts have composite primary keys and one-to-one relationships. Any clues what to do here? This is pretty important that i get this to work.

  • EF4 generates invalid script

    - by Jaxidian
    When I right-click in a .EDMX file and click Generate Database From Model, the resulting script is obviously wrong because of the table names. What it generates is the following script. Note the table names in the DROP TABLE part versus the CREATE TABLE part. Why is this inconsistent? This is obviously not a reusable script. What I created was an Entity named "Address" and an Entity named "Company", etc (all singular). The EntitySet names are pluralized. The "Pluralize New Objects" boolean does not change this either. So what's the deal? For what it's worth, I originally generated the EDMX by pointing it to a database that had tables with non-pluralized names and now that I've made some changes, I want to go back the other way. I'd like to have the option to go back and forth as neither the db-first nor the model-first model is ideal in all scenarios, and I have the control to ensure that there will be no merging issues from multiple people going both ways at the same time. -- -------------------------------------------------- -- Dropping existing FOREIGN KEY constraints -- NOTE: if the constraint does not exist, an ignorable error will be reported. -- -------------------------------------------------- ALTER TABLE [Address] DROP CONSTRAINT [FK_Address_StateID-State_ID];

  • Architecture choice about representation of collections in Business Objects

    - by Rajarshi
    I have made certain choices in my architecture which I request the community to review and comment. I am breaking up the post in smaller sections to make it easier to understand the context and then suggest/comment. I am sorry that the post is long, but is required to explain the context. What am I building A typical business application where there are application users, security roles, business operation/action rights based on roles and several business modules like Stock Receive, Stock Transfer, Sale Order, Sale Invoice, Sale Return, Stock Audit etc. and several reports. The application is a WinForm application since it has a lot of rich and responsive UI requirements and has to operate in disconnected mode (with a local SQL Server), most of the time. What have I done I have built a framework - nothing to boast about, but just a set of libraries that serves the repetative requirements of my application, e.g. authentication, role based authorization, data access, validation, exception handling, logging, change status tracking, presentation model compliance and reasonable loose coupling between components. No, I have not written everything from scratch, you can say I have consolidated many things together like some concepts from CSLA, Martin Fowler for Presentation Model, blocks from Enterprise Library, Unity etc. to build a set of libraries that will help my developers be productive quickly without having to look up Google for many of the technical requirements. I have tried to keep the framework generic so that it can be used in typical business applications and also tried to follow some best practices that will support the same Business Objects to be used in an ASP.NET MVC environment also. My present architecture serves my objectives well, and have built several modules (on WinForm) without much trouble. The architecture also lent itself well to build some usable prototype on ASP.NET MVC with the same set of business objects, without changing a single line of code. My Dilemma I have used Custom Business Objects since that gives me a clearer OOP representation of the problem scope in my solution scope, and helps me visualize my entire solution as collection of objects with data and behavior rather than having a set of relational data (DataSet) and implement behaviours (business logic, validation) etc. separately. With rich databinding support in .NET 2.0 binding Custom Business Objects to UI was a breeze. Now while building my business objects, I am still in a dilemma about representation of collections in business objects. Currently I am using DataSets to represent collections while I have seen many suggestions to implement custom collections. For example, in my vision, a typical Sale Invoice Object will contain 'Sales Invoice Items' as a collection. Now theoritically, I can accept that the each 'Sales Invoice Item' should have its own behavior along with their data (ItemCode, Name, Qty, Price etc.) but typically managing of Sale Invoice Items in a Sale Invoice is handled by the Sale Invoice Object itself, e.g. adding/removing Items from collection. Additionally, we can also put business logic/rules for the Sales Invoice Items like "Qty should not be greater than the ordered qty", "Price should be max 10% above the price in Sale Order" etc. in the Sale Invoice object itself. With that kind of a vision, I felt that most business object child collections can be managed by the parent itself, including add/remove from collection as well and implementing business logic for the collection items, hence the collection items hold nothing but data. Additionally, typical collections are represented in UI in Grids, where ability to support DataBinding becomes very important for any collection. Implementing a custom collection, in that case would also mean, I have to implement robust DataBinding support as well, for the collection, which is of course time consuming. Now, considering child collection behaviors are implemented in the parent and the need for DataBinding of child collections, I chose DataSet to represent any child collection in my business objects. In the above example of Sale Invoice I will have 'Invoice Number', 'Date', 'Customer' etc. as attributes of the 'Sale Invoice' but 'InvoiceItems' as a DataSet. Of course, when I say DataSet, it is not a vanilla dataset but an extended DataSet that supports business rule validation and the same role based security model of my framework to allow/deny any business operation to rows/columns of the DataSet, automatically. This approach has allowed easier collection management and databinding in my business objects and my developers are able to deliver modules rapidly. Questions Do you feel that the approach is reasonable? Do you see any shortcomings of this approach? I am recently thinking of using 'Typed DataSets' as child collections, for easier representation in code, that will allow me to write 'currentInvoice.InvoiceItems' (for the DataTable) and 'invoiceItem.ProductCode' or 'invoiceItem.Qty', instead of 'drow["ProductCode"].ToString()' or '(int)drow["Qty"]' etc. Does this choice have any demerits? Thank you if you have read so far and a salute if you still have the Energy to answer.
