This message relates to a problem which occurred earlier this evening with my Acer Aspire Model G600 PC.
I booted the system at around 4pm in order to print-off some information. the system all appeared to work just fine. I identified the folder containing the work that required printing and after identifying the exact files sent them to the printer for printing, where upon the black ink cartridge showed a low ink warning. I aborted the print and went off to find a new ink cart. Whilst getting the replacement ink cart I was asked to do some other things and as a consequence didn't get back to the PC for about 40 minutes. At this point there was a message on the screen saying that the chosen documents had failed to print (something that I have seen quite frequently before when changing ink carts, so I didn't think anything of it until I went to move the mouse. It seemed that the whole syatem had locked-up and there was no visible mouse pointer. I tried ALT CONTROL DELETE but even this didn't do anything, so I resorted to switching the entire system off, and then back on after about 15 seconds. As soon as the system powered up I noticed that the green light behind the ON button did not seem to be as bright, I think because there are more than one LED situated there, and maybe one or more are not lighting as usual (although I cannot confirm this). The system sounds to be starting, there is some limited hard-drive chatter and some of the normal sounds made by the DVD ROM and DVD-RW drives, but this all rapidly stops and the system just sits there doing nothing. The leds on the keyboard are all blinking on and off rapidly (something I have never seen before on this system). After a very short time (a few seconds after switch on, the led behind the ON button just goes off altogether!). There also appears no drive to the TFT display so I guess I can't get into BIOs.

I tried to think rationally, and so unplugged all USB and other devices from the unit, in case one of these was causing a fault. No luck.

Using an anti-static wrist strap, I removed any cards that I have added to the system over time from the expansion slots, in case one of these was causing the fault. No luck.

I disconnected all but the FDD and Hard Drive. No obvious improvement.

I tried replacing the PSU with a known working unit. No Luck.

DO I assume the thing I fear the most - that the motherboard is 'fried!'.
Or, is there something stupid that you know I am overlooking?

I cannot see a Makers name on the motherboard, but it does display the following - M7NCG VER.3.

the PC is a Pentium 4, with 512meg ram. If you feel that the main board is the problem, would I be able to replace the PCB, or would you replace the whole base unit? If I replace the board, should I also replace the Processor, as presumably this could be the problem. How can I tell? Am I able to purchase a motherboard with processor fitted, as I am not really confident about inserting a new processor onto a PCB.

Incidentally, I am not absolutely certain, but I am not aware of the system making any alarm beeps at boot-up. Is this relevant.


In other words.........HELP!!

Howard: The M7NCG is a Biostar motherboard and is an AMD board so it cannot use a Pentium 4 processor. You are reading something wrong.
Post your specs on this machine so we can try to diagnose your problem.

Something told me that the processor was a pentium 4, but now i have had a rethink, I believe it is actually a AMD Athlon 2800. I know that the rest of the info relating to the amount of RAM etc. is correct. The mainboard has a onboard Nvidia processor, but I added a somewhat better spec. graphics card, a TV capture card, additional 4 socket USB card, all of which are currently removed. Does this help?

Howard: I don't think the motherboard or CPU is fried. Go into Device Manager and seee if you have any Yellow flags there. They usually indicate a lost or corrupted driver.
The fact that it shuts down suddenly may indicate a heat problem. Can you just run the computer with the side off and check that all the fans are running? Check the ones in the PSU too.
