editRAM compatibility
editHi, my computer mainboard support up to DDR333/PC2700 RAM (using sis650 chipset) . Can it use DDR400/PC3200 and run it at 166MHz (the speed of ddr333/pc2700) i.e. underclock without any crash or instability ? Rockvee 03:02, 1 July 2007 (UTC)
- Yes. --antilivedT | C | G 03:45, 1 July 2007 (UTC)
- Thanks. That was my first feeling. I saw some computer store sell same brand same sized RAM which pc2700 has a higher price tag than pc3200. Are they trying to trick us or what?Rockvee 03:56, 1 July 2007 (UTC)
- Yea it's kinda illogical but the PC2700 may be better made (using better chips etc.) than the cheapest PC3200 ones, or just to trick people for their "incompatibility". --antilivedT | C | G 04:02, 1 July 2007 (UTC)
- OK. Just to make sure, can I use PC2700 and PC3200 at the same time? Rockvee 04:15, 1 July 2007 (UTC)
- Yes you can use them both at the same time, at their lowest common speed (in this case PC2700). If you want Dual-channel you'll need same capacity sticks though. --antilivedT | C | G 04:28, 1 July 2007 (UTC)
Ok thank you very much Antilived :D Rockvee 04:34, 1 July 2007 (UTC)
Can a .pdf file be infested with a virus?
editI got an email from some spammer with an attached .pdf file. I didn't open the file, of course, but I was wondering if there have been cases of .pdf files being infested with virii? Corvus cornix 03:14, 1 July 2007 (UTC)
- PDF files can run some scripts. There had been PDF worms using embedded visual basic scripts. Here it is said that Acrobat Reader is not vulnerable because it cannot run embedded files. -- ReyBrujo 03:31, 1 July 2007 (UTC)
- So then if I had opened the attachment and pdf reader got started, there would not have been a problem? Corvus cornix 03:48, 1 July 2007 (UTC)
- It seems that spammers are using PDF instead of images to have their spam contents (usually trying to pump up the price of some odd stock)
- Any file can be infected with a virus, but some document files ment to to be opened by programs might stand a chance (very unlikely), viruses can be encrypted into PDF files; this file you got, do not open it! Tcrow777 talk 00:34, 8 July 2007 (UTC)
I've just set up a M0n0wall server for routing and traffic shaping and it seems to run well. I have a modem/router to my ADSL that's at 192.168.0.1, which connects to the WAN port on my M0n0wall server and my computer connected to the LAN port side. I can go online from my computer, but I just can't access my modem's config page. I can ping it, but otherwise it just times out if I tried to HTTP or telnet into it. Also, I can't set my computer to static IP address anymore, no matter what IP I put for the gateway (tried both M0n0wall and modem's address). Can anyone help me? I'm quite new at these network stuff. --antilivedT | C | G 03:50, 1 July 2007 (UTC)
- Turn off the client and you can ping it as easy as a pie. AW 02:28, 2 July 2007 (UTC)
- Huh? What client? And I can ping it no problem anyways, it's just that I can't HTTP into it. --antilivedT | C | G 06:23, 2 July 2007 (UTC)
- OK, it's just a joke. I'm not sure if I can help, anyway. To solve the problem, you should give more details about your modem (product, manufacturer, revision...). Have you changed the default password of your modem? See this list for pass of each type of modem. As you say, you couldn't telnet or http it. Now the only way is to reset the modem, reconfig and remember not to tick the line "Prevent access to 192.168.0.1". Hope this help. AW 08:39, 2 July 2007 (UTC)
- No I can HTTP into my modem no problem when I'm directly connected to it, but I can't do it if it goes through my M0n0wall server. --antilivedT | C | G 11:45, 2 July 2007 (UTC)
- OK I've solved it myself: I turned on the half-bridge mode on my modem so my m0n0wall box have the external IP and then I can access the modem's configuration page if the "Block LAN traffic on WAN port" setting on M0n0wall is not set. --antilivedT | C | G 09:24, 3 July 2007 (UTC)

Youtube Burning
editHello. Anybody happen to know how to burn a Youtube video on to a blank DVD? Thank-you!Jk31213 04:00, 1 July 2007 (UTC)
- Have a look at this page. It downloads the file, you'll need an FLV player to view the video (such as VLC media player). - Akamad 04:12, 1 July 2007 (UTC)
- After you download it to an FLV, you can use the SUPER video converter to convert it to VOB format and burn it to a DVD. I think that would work, although I'm not entirely sure. --ParakeetSong 08:19, 1 July 2007 (UTC)
- Total video converter is another suggestion for conversion. AW 02:08, 2 July 2007 (UTC)

Microsoft Word Problem! Please Help!
editHi I'm using Microsoft Word 2003 and this problem seems to be getting out of hand. Whenever I try to copy a picture and paste it in a document, instead of the picture appearing a white box occurs. I tried copying different pictures and the picture doesn't appear in the document. Furthermore, when I copy a chunk of text with pictures in between from a website and paste it in word, only the text shows, the image part shows stuff like "<IMG.." or something similar to that. Even if I download documents with image added in, the image does not display but only that small tag
Anybody help?? I need to paste this picture in the file for my coursework!
- Some things to try in the meantime:
- In Word, try zooming out, and waiting a few seconds
- Try clearing your internet cache (Temporary Internet Files). In Internet Explorer 7.0 , click Tools -> Delete Browsing History... Then next to "Temporary Internet Files" click "Delete Files"
- Rfwoolf 13:16, 1 July 2007 (UTC)
- Instead of "copy paste", try saving the picture to your computer, and then use the Insert Picture (in the Insert menu). This may help. Nimur 17:22, 1 July 2007 (UTC)
- Yeah, I recommend using the Insert process. Corvus cornix 18:59, 1 July 2007 (UTC)
- Maybe the problem comes from your firewall. Try changing the default from "high" or "medium" to "low". I'm not sure this can help. If it doesn't work, get advice from this. AW 02:39, 2 July 2007 (UTC)

Noo! I tried inserting and what I get is a blank picture with borders around it! Right clicking it to format it doesn't work! The button "Format picture" is not visible when I right-click! What do I do?! I just re-installed it and when I paste a picture into word document, this is what I get {INCLUDEPICTURE "http://office.microsoft.com/global/images/default.aspx?assetid=ZA100741741033"\* MERGEFORMATINET} Does it mean anything? Please help me fix it :(!
- That URL is not for the photo, at least not directly. That tells the webserver to go out and retrieve a specific file with "asset ID" ZA1007.... You need to get the actual JPEG file onto your computer, and then insert it into your Word doc. --LarryMac | Talk 20:35, 2 July 2007 (UTC)
