    Thanks for the response... I appreciate it.

    The PC is a Micron Millennia with the following system components from mpc: (previous mistake on motherboard, Garibaldi)

    CD-ROM Drive Lite-On 52X IDE CD-ROM LTN526 CDI001263-00

    Processor Intel Pentium IIII 1.9GHz 400FSB 256K Socket W CPU002058-00

    Case Odyssey Base.Chassis.W/300W 12V PWS CSE001633-00

    Floppy Drive Panasonic 3.5 in. Floppy Drive FDD001234-00

    Keyboard Lite-On SK-1688A 104 Keyboard KBR001118-00

    Motherboard Garibaldi II - Intel (Standard 4) (P4) Motherboard MBD001150-04

    Modem 3Com V.90 PCI Modem (Condor) MDM001045-02

    Software 3COM 3C90x NIC Family Media Kit MED001271-04

    Video Card MATROX G450 32 MB SGRAM.MEDIA MED001388-01

    Memory 64M x 16 128MB 800MHz RDRAM RIMM MOD001849-00 (UPGRADED TO 256 MB)

    Network Interface Card 3COM 3C905CX 10/100 Network Interface Card NWO001481-00

    Memory Rambus Continuity Module (Compec) PCB001155-00

    Software Windows XP, Symantec Endpoint Security Sofware

    Video Card Matrox G450 Dual-Head 32MB AGP Video Card VCD001470-03

    The PC is intermittant, ususally after two hours of wait time, I can boot, go through auto scandisk/chkdsk, backup a few files and then the CPU fan stops, followed by the case fan then the motherboard and all components power off. There are two lights near the power button, one amber the other green. When the PC shuts down, the green light extinguishes and the amber light (moon) illuminates. I can press it for 5 seconds and the amber light extinguishes. After that the PC does not respond other than the amber light on and off. The mother board has a green LED (CR6FI) that stays illuminated while I have the power cable connected and goes off when the cable is unplugged.

    Additionally, I changed the CR2032 watch battery, swapped the AGP video card for a backup PCI video card, ensured all SRAMS are inserted and seated, unplugged the power lead to the mother board and reseated it back into the motherboard, all to no avail.

    Thanks again epr1977

Thanks again, I've had trouble all day attempting to reload Intel Active Monitor, to the point where I attempted the patch for XP and even editing the Registry to try and remove an older version for eventual upgrade to the newer version, no luck in getting the new version to load due to the setup identifying an older version. I will attempt dropping the RAM to I believe the first pairs.

    I've seen similar problems; all of those, are related to the power supply. Is there a way you can try another similar power supply?....

    another recommendations:

    -Just leave one chip of memory

    -Does the driver for the motherboard has any diagnostics for the temperature of the processor. sometimes if the processor is not cooling enough it will shutdown automatically.

Inspiron 518 - intermittent power up, amber light blinks once and then stays off

Usually if it has boot issues it is from the ram memory ..specially if it does like you said ..only ask for repeated action when it is cold..So , check the ram memory to be well plugged in ..and if you made changes , check for the specs on the newer ram module and be sure it is not on a higher speed or so ..cause it will not read it well and issues will be caused by it ..
another thing can be some bad points on the hard disk ..and if you get a bad on the system it may fail to load for good..The idea is to reinstall the operation system from scratch using a boot-able disk ..and this may fix the issue for the moment ..until it will be stuck with a system file in a weak point ..
The reinstalling is recommended also in case you added more ram memory and never reinstalled This action will force the computer to recognize the ram memory in proper way and run better ..
If you see it is always makes issues when you put it to sleep mode or shut down may enable the hibernate mode (from the power management panel ..(somewhere near the screen saver settings in the desktop properties ) ..and after that select for the actions when you press the main button to go to hibernate mode..This mode will always save what you have running and it is slightly different from the shut down cause it saves the running program and teh configuration used on moment ..and just load back the same way ..and it may force it to use the same points on the hard disk all over again when it starts ..
I used this mode on computers with hard disk issues and it always worked better than starting over again ..
I hope it was helpful and please do not forget to rate my answer ..
Have a good day !

Computer locked as though in sleep mode - screen dark grey colour. Power light lit and 'moon' illuminated. Any ideas hoe to unlock?

Remove the battery and mains and hold the power button down for 30-60 secs, then replace battery and mains. It should now hopefully turn on.

Compaq presario CQ50 106CA. When powered on the power light and wireless light illuminates. The DVD sounds like it's initialising and fan runs, but screen blank. Ihave tried all basic fault finding...

Have you tried turning it on and selecting the function key combination for the screen? For example some screens use FN+F7, hold down the Function key and F7 to cycle between presentation modes.

Amber colored power light on eMachine W3503

The amber power light indicates that your computer has been "sleeping" or "hibernating" and usually all it takes to restart the computer is tapping a key on the keyboard. If this is not the case, try holding the Power switch down for 6-10 seconds to force the system off. Restart in Safe Mode and try to find the settings for Sleep/hibernate, open the control panel and open the Screen Saver. Select "Change Power Settings" and set it for "Never" on sleep and hybernate.

What does the half moon lit up mean, No screen.

The half moon usually means the computer is in SLEEP MODE. Normally, pressing the spacebar will wake the computer up but I have noticed that sometimes, the computer can get "stuck" in sleep mode. If that is the case, you can hold the power button down (until the power turns off and the moon disappears). Wait a few seconds then hit the power button again to turn the laptop back on.

can you try this? unplug the pc, hold down the power switch until the amber light goes off, then (with the pc still unplugged) push the power button to see if the amber light comes back on, if it does, repeat the first step. do this until no light comes on when the power button is pushed. after you've done this. plug the pc back up, then hit the power button. what happens?

ive had this happen to a lot of my dell pc's here at work, but all i can figure out is that its a mobo problem, i also have tried swapping PSU's, but it didnt help.
