Specs: Microsoft Windows XP Professional, 1.995 GHz / 1471 MB
i have a msi k9vgm-v ms-7253 ver:1.1 it will not power on the power led flashes that is all it does i had it on a 300 watt power supply with a amd athlon 3800+ socket am2 processor and 1 cd rom drive and one ide 80 gig hard drive no other add on cards were installed all onboard is what i was trying to run

If this system was working fine previously and you have NOT been fiddling with connections inside the case and have NOT changed which ram is installed in it since it last worked....

Failing power supplies are common and can cause your symptoms.
Check your PS.
They often partially work, fans and hard drives may spin, leds may come on, yet you get no video and the mboard will not boot all the way.

i changed the power supply to one that i just took out of my other pc and it still doesn't work it will not turn on at all the only thing that happens is as soon as you plug the power to it the power light on the front of the pc flashes

Did you have a power failure event, or did you try to flash the bios, before the problem in the first post?


Did this apply intially??:

"If this system was working fine previously and you have NOT been fiddling with connections inside the case and have NOT changed which ram is installed in it since it last worked...."

E.g. installing ram that is not compatible with the mboard can cause your mboard to NOT BOOT in the worst cases.

Did the PS from the working computer have at least 300 watts capacity?
Did you remember to plug in the extra power connector from the PS to the mboard other than the main 20 or 24 "pin" one?

If yes to both, or in any case.....
power supplies sometimes damage something else other than themselves while failing. That's especially likely if the PS is an el-cheapo.
What's the make and model of the original PS?
........

Unplug the case/power supply.
Power off your monitor.
Check all the connections of the wiring to make sure they are all the way onto their pins and into their sockets, especially the main connector from the power supply. The wires close to the mboard going into the main connector/socket should be more or less perpendicular to the mboard surface rather than at an angle. Make sure all cards in slots are all the way down in their slots.

While you're in there, if the cpu fan/heatsink has mung (dust, lint, etc.) on it, clean it off, but DO NOT use a vaccuum cleaner to do that (they produce a tremendous amount of static electricity when running, and anything connected to them can discharge that to your components) - use canned air, or an air nozzle if you have access to an air compressor, or an artist's brush that can be used in small spaces, etc. It may be difficult to clean the top of the heatsink under the cpu fan - the most likely place to have mung on it - and the bottom side of the cpu fan blades unless you remove the fan. If you have a case fan, clean that too if it needs it.

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:

the ps i took out was a asus 300 watt the one i put in is a hippro 300 watt also there is no cards installed it was running all onboard i tried cleaning the ram it has no dust on any thing in it i used a duster can to blow it out for electronics the ram it has in it is ddr2 800 in it 1 gig i have no clue what is up with it besides it is a pos lol

You haven't answered all of my questions.
.......

Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

This was the original bad capacitor problem - has some example pictures.
History of why the exploding capacitors and which mboard makers were affected:

What to look for, mboard symptoms, example pictures:

- what the problem is caused by
- he says there are STILL bad capacitors on more recent mboards.

Did you try this:

............

If you have tried or examined EVERYTHING I have mentioned above......

Is there a possibilty this computer was exposed to
- a nearby lightning strike?
- a static electricity discharge, such as if it's in a location with synthetic wall to wall carpet and the humidity is low there?

Sometimes a defective drive can cause strange problems, especially if it's logic board has failed - .
Try unplugging all drives, with the AC power to the case removed - and then trying to boot

If you have a floppy drive and when it's hooked up, does the led for it light up, AFTER the usual brief flash you usually see while booting when there's no floppy in it, for a while, then go out?

If the led is on all the time after attempting to boot, one end of the data cable is installed backwards - that can cause booting problems.

Have you ever had a PCI-E X16 video card installed, or other cards installed in slots, on this mboard?

Try removing the mboard battery for a few minutes, with the AC power to the case removed, re-installing it.

If it then boots, you will have to set the date and time in the bios Setup

Did you move the clear cmos jumper?
If you did, did you place it back on the pins for "normal" - the mboard may not boot if that isn't on the proper pins, or if you removed it and didn't put it back on.

Alternately, you could try moving the clear cmos jumper with the AC power to the case removed, moving it back, but you may need to consult the mboard manual regarding that - the markingson the mboard can be confusing.
.......

If none of the above helped, you have truly done and checked everything, if it doesn't pass this test it's probably dead.

Make sure you have a speaker or speakers or the equivalent connected to the mboard so you can hear mboard beeps (see your mboard manual if you need to).
Remove the AC power to the case/power supply.
Remove all the ram.
Restore AC power.
Try to boot.
If nothing else is wrong, you will get no video but you will hear a pattern of beeps that indicate no ram is installed, or a ram problem.
E.g. for an Award bios or a bios based on one, that's often a beep of about a half second, silence for a half second, a beep of about a half second, silence for a half second, continuously.
.......

In most cases, there's nothing wrong with any of the other components, and replacing the mboard with one that can use the same pieces yields you a working system.
