I dont know what the hell has happend to my PC  . after winXp is loaded, few(varies from two minutes to 20 min) minutes later gets rebooted as if you "unplug-n-Plug" the power cable. Before restarting, the monitor flickrs, the small light in the mouse dims and brightens.. then.. f*cking restart.
I changed SMPS.
I Gave motherboard for service.
I removed mouse.
I removed NIC.
I removed USB.
i removed everything.
It works well in DOS command prompt (and in the BIOS screen atleast)
what could be the problem ? someone please help me get a clue.

can a virus go down to that level?? if its in DOS i'd believe it.

okie, i have another back up HDD, i'll try with that.

Bad memory chip. I had that exact behavior happen to me once.

Eeek!
BTW, I could be wrong! I mean, there are lots of failure points. But let me know how it turns out.

No problem Marc!!  .. atleast i get some hope to repair it. and moreover i'm happy for this moment.

The only thing i didn't replace was the RAM. damn.. see what i do today. i'll surely burn it on fire. grrrrrrrr.. that took me almost a month to identify.. almost damaging my HDD and getting the blame on my innocent SMPS, MotherBoard and even Mouse( ).. i even thought the problem is with the PS2 connector with the board( i have a old 810 board)... hmm i hope this would be the judgement day. thanks again Marc.

This could also be a temperature problem. Check the fans and heat sinks in your machine.

Yup, all fans are running. and moreover, in 2 minutes how does it get that hot??

You would be surprised. The CPU fan on my box at home failed. Sitting idle, it would crash in 10-15 minutes. If I started a game, it would die a minute or two later.
You may also want to check the heat sink on your CPU and/or your graphics card. I had a retaining clip on a CPU heat sink come loose once that caused a problem. I think it happened when I plugged in a card.

hmm..i'll see to that. but you described it a "crash".. , but my case just restarts...

yeah sure. i'll check the CPU heat sink.. No graphics card with me. everything onboard but low end.

Sounds like overheating to me. Try this: Take the case off, get a little desk fan and point it at the motherboard (probably the CPU/RAM is the best place to aim). If the computer works ok, you need to improve the cooling in the case.

Try number 32 :

I'll do that  .But do you think, the the fault can be with the SMPS-Motherboar power connection point. i tried changing the SMPS. but still the problem is there. but wait a minute. everything works fine in DOS. HOW??..as said by mark, i feel like turning the aim on RAM again. i'm waiting for a spare RAM from my friend. once i get it, i'll see it that's the point. or i'd move on to try number 33.

I've occasionally had to swap power Supplies out after 2-3 years due to weird drops in voltage (usually on the +12V rail). If you've swapped out everything but RAM and PSU you may want to get a tester (some of the simples ones run only 20-30 bucks)
Hope you can pin down the fail point.

If you think it's the ram, and it's happened to me too. Then try memtest86 at memtest86.com I like the ability to make a bootable cd myself from an iso. Anyway If you have 2 chips just pull one and test it, then try the other.
Make sure you put it into extended test mode since I had one that would only fail when I did that.
My experience with this type of problem has always been, RAM, Cooling, bad power supply, and once a bad CPU. Most of the time it's RAM and Cooling though.

your system might be infected with virus. try installing an antivirus program.

Hi There,
I am trying to import NMEA protocol from Magellan brand Meridian gold GPS into matlab through serial port and getting port is not avilable and time out.

I have written a program using C++ in my personal computer. It is an image processing application which performs basic function like edge detection/ histogram equaliztion etc.
Now i would like to move it out of the PC into a stand alone h/w system where i feed the pixel values and i get the processed pixel values as output.
I understand that this area is known as Embedded Systems.
I have my PC, a few image processing algorithms and a book on emebdded systes design. What more (h/w and s/w) will i need to convert my PC based program to a stand alone system?
I am a novice when it comes to h/w , so please pardon incase me post sounds funny to anyone here

basically it will come down to your choice in embedded system. There are few standards in embedded systems. In fact you can even get a PC based embedded system, kiosk style or much smaller. Image collection will be even less uniform, we use one brand of capture boards which includes a image processing library (though we found that Intel's was faster).
In the end, "how" will come down to what hardware you choose for the embedded system.

Hi everybody,
I want to transfer files between 2 computers by the modems. I don't know if there's any library or API functions I can use. Help me if you have any idea. Thanks a lot.

In which language you are expecting the solution.

I think Visual C is appropriate.
