Yes your right, it's bios error, it won't beep at all when I start it
I've been mixing a little with some harddrives and cd drives... But that can't be the problem, couse bios would start anyway...
I hear everything spin up, but then I don't know what happends...

If it's not beeping the problem is probably something other than the bios. A failing power supply (bringing some power but not enough), or dead cpu would be more likely. If you have a multimeter you can check the former. Stick the probes into both a spare drive connector and the one on the mobo (a loose connection, or failing mobo parts could make the voltage levels different here than on a drive connector). Black to Red should be 5V, Black to Yellow 12V. A deviation of +-5% is within accepted bounds, more than that could be the problem.

OK, I don't got a multimeter... I think my dad got one, but he's  now.
I'll have to do it tomorrow...

I take it this same screen and graphics card have worked together before?
You'll have to forgive me for asking a few questions before I can say anything else.
Does the machine actually turn on and post? You should hear one short beep on startup. If you hear any other number of beeps look here[^] if you hear "no beeps" indicating no POST operation occurs take it to a shop, or look here.[^]
outside of that, you can check to make sure the VGA cable is connected tight (a loose connection can decide to move enough to stop connection just by time and gravity). Make sure you have the right VGA cable connected (some monitors have more than one input).
Without more information on what is happening durint POST I can't help much. If it is the video, and you have a friend who lets you open up machines, you can swap video cards. If your computer boots normally on his card, and his computer does not show video, you know the problem is with the graphics card and can replace it (thank him with a beer/soda as per his preference and head off to the store).
The easiest way to troubleshoot failed technology is with spare parts, making it more difficult for the average person. With some more details on what the computer is doing, can you pop the case open (preferably without damage) and peek to make sure the video card is plugged in, CPU fan starts turning (and GPU fan if appropriate). Any northbridge cooling that is on the motherboard also, basically if it has a fan, make sure it is turning. If not, that's a strong indication of where a problem started, though it may not end there.

Thanks for your reply.

I didn't think of the possibility of bios errors...

Does anyone have a link or article featuring the components and roles of the video card? If you also have a link or article for data routing in video capturing (recording and previewing) it would be much appreciated... This is because I want to know how it is related to video recording. We are having problems with simultaneoudly capturing video using 4 usb webcams(same brand and model). We pin-pointed that the video card may be the source of our problem... Thank you very much...

I can't find the one I was looking for. This may help a little as far as explaining the complexity of the graphics system: Windowing_System_on_a_3D_Pipeline_Slides.pdf[^]
Now, until Vista, the windowing manager is not within the 3D pipeline, it is consider a raster only process. Most of a raster process in the IO to the card.

I'm looking for a cheap laptop (probably new not second-hand) for a student. Mainly for word processing, a bit of spreadsheet stuff, etc. Certainly no programming, and I don't care about games!
Since it is certain to be lost / stolen / broken / filled with coffee, I have no interest in buying anything even remotely state-of-the-art.
I have seen a laptop using 1GHz VIA C1, 256Meg RAM, 40Gig HD, WinXP Home, for 25% cheaper than any other new laptops. Any comments?
|
|
|
|

IIRC the via chip only does half/cycle as a p3/athlon does, so performance wise it's a athlon 500, or p4 650. Shouldn't matter for what you intend but you should be aware of what you're actaully getting.

Thanks.
For what it's worth, I got the processor wrong - it's a VIA C3, not C1.
I found some reviews (Tom's Hardware, etc) which indicate that the floating point unit on a C3 is lousy.
On benchmarks, the 1GHz C3 performs between a 433MHz Celeron and a 1GHz Celeron (depends on the test.)
Since I was happy until recently with my 667 MHz Celeron (when I wasn't building projects in Visual Studio 6), a student can live with a 1GHz C3 notebook!

I've got a compaq presario notebook with a relatively small and slow 60Gb/4,200rpm drive. I want to upgrade to something bigger and faster but I'm having trouble finding info on the type of drive I need.
The drive I have has 2 rows of female connectors. The drives I've seen have 2 rows of male connectors. I'm assuming this is a UDMA/ATA issue but googling has only muddied the water.
Can anyone give me the low-down?
cheers,

Whats the model of your notebook? I have only seen notebook HDDs with male connectors.

Well found this pdf[^] on this page[^]. On page 5-16 of this pdf look for "To Replace the Hard Drive Holder". This section mentions how to reuse "holder" from old HDD. I hope that helps.

[Edit: Mystery solved. Your pointer to the PDF about the holder made me open up the case again to have another look. Lo and behold there's a gender-bender attached snug to the HDD. I'm back on track]
Thanks! Just a pity that the illustration and what I have in front of me are completely different!
No holder, just a HDD with female bits.

Hello,
I am developing a project and l need to be able to access the infrared port on my computer.
My project has 2 applications that run on 2 notebook computers. I have data that I have on one notebook that has to be sent to another notebook.
The client will click a button and all the data that is being displayed in the text boxes will be sent to another notebook to be displayed in some other text boxes.
Does anyone know how to do this. I am using the c# language.
Thanks in advance,
Steve

when I am executing SET MAX ADDRESS(0xF9) of ATA command, it is Aborting...For Aborting there are 2 reasons specified in "IBM HD Spec.pdf"
> when Volatility bit -1 for permanent removing of HPA is specified and in Address offset mode, command is aborted...
> READ_NATIVE_MAX_ADDRESS should be immediately called before SET MAX ADDRESS, otherwise command is aborted...
I wish to remove HPA temperorily and take care of the above 2 precautions, still SET_MAX command is aborting... IDENTIFY_DEVICE, READ_NATIVE_MAX_ADDRESS cmds are executing perfectly...
Before executing READ_NATIVE_MAX_ADDRESS, IDENTIFY_DEVICE cmd is executed...When IDENTIFY DEVICE cmd is issued 10th bit of word 82 is 0 returned by device i.e, HPA feature set is not supported...If that is the case, I'm able to execute READ_NATIVE_MAX_ADDRESS CMD and with one tool I'm able to create & remove HPA...
Please send me suggestions or solution if possible for not aborting SET MAX ADDRESS cmd....
Regards,
mohan.

I am trying to send ATAPI commands to a cdrom in VB.Net. While researching this it seems to me the VB is not the best at this. I am sure their is a way though. Can anyone steer me in the right direction? I read something on calling the Windows API to do some hardware speaking, but it said that that is being Phased out with VB.Net.
I am able to send these commands through 2 other test programs that we use.
Thanks!
Ken

I am Sushanti, Msc Part 2 student from Mumbai, India. I have selected JTAPI as my project topic. Till now I have planned to add the following features in my project :
1) Making phone calls from PC.
2) Receiving phone calls.
and if possible
3) Conference
4) transfer
5) answering machine
I have downloaded JTAPI 1.2 class files. My java files are getting compiled successfully. I have doubts regarding the hardware
configuration required to run these. Will I be able to really make a call by using a microphone, speaker or even by using our modem. Is cost required for each call. Is a provider service is obligatory. How should I go ahead with this project if I won't be able to show the examiner the call really being processed. Need your guidance in this. Waiting for your positive response.

hello there
we did a similar project in VB for our final year engineering... you need a modem... a full duplux voice modem.... and ofcourse a phone line connected to the modem.... making calls through PC is like having phone instrument virtually in the PC.... call charges and others are same as that of using a phone... u wont need any special hardware..... actually you can show the examinar the real process like we did.... Note: remember we did our project in VB using TAPI... we have some dll's and ocx using that we did this project.... our project is an answering machine.... it is going to be implemented in our college... our project is like when a parent or some one calls this number the PC will pickup the call and ask for the detail they want, like college detail or student detail then the calling party can respond by pressing option number in their phone.. the software will read this signal called DTMF and then respond as per the option or choice dont worry this is simple and if you have any other doubts you message me........ my email id is urdreammaker@rediffmail.com

You're taking on a huge project for a student, but it can be done. I think you may have found a great resource in Madhu - he's been there, done that. I found TAPI utterly baffling when I attacked it with VC++ and the MFC classes, but the Java community has done a far better job of implementing classes for communications of all kinds than Microsoft has ever done. I would certainly embrace any ideas that Madhu offers and run with them. Spend some time on the Sun website, too. They offer some very good tutorial material and sample code, if you can find it. The website isn't organized as well as it could be, but it's an excellent resource. Best of luck to you....
BTW - When you're done with this project, it will be a great article to post here to help others learn from your experiences.

hi
Tapi is difficult but possible and i have used ocx so it was quite easy like wise you can refer for helps in jtapi which will help you a lot.... you will be able to finish your project only if you try using available functions... if you try to implement functions then that itself will become a project........ take care

In your opinion, what is the best laptop for programmers? What attributes make a laptop better suited for programmers?
Currently, I have a Thinkpad T40 and find it more than adequate. Getting a little old though, so I thought I would ask.
