On my desktop witch has a asus P5DV-VM SE




By aouate_chris on Jul 26, 2009

on my desktop witch has a asus P5DV-VM SE motherboard with a 2.77ghz processor a 512mb of non-ecc non-buffered ram with a thermaltake powersupply @ 430 watts, when i power it on it shows the post but then shuts down immediately, when i press the power button again it seems like it trys to power up (like it would if it was running on a low battery), at first i thought the power supply was bad (i just built the desktop today from parts i had laying around) so i replaced the power supply with another one, still shut off, tried another one, still shut off, so i tried about 5 more, still the same, i moved the parts to abit motherboard that took the same parts, the same thing happened, all the power supplys i was using were either 430 watt or lower, does a socket 775 motherboard like this one take a higher wattage?

- i tried that before, i will try it again and tell you what happens

- nope, still didnt stay on, could is possibly be the processor? it has thermel paste, and the pc shows the post, so i think the processor works

- and it doesnt give any error beeps, it shows the post then turns off, and when i press the power button immedially afterwards the fan revs and dies, if i give it a little time, then when i press thee power button it powers up, shows post, and powers off, i even tried taking out the motherboard and powersupply and connecting it without a chassis and used a old switch i had to turn it on and it did the same thing

- if it is overheating (just a idea) should i try putting a shitload of fans in it to see if it lasts any longer before it powers off, (again, just a idea)

Jul 27, 2009

- all the fans are connected

- im hoping its not the processor because i dont have one another one like it and me being only 14 years old, i dont exactly have enough money to go out and buy one, i have been repairing and building desktops and laptops for about 5-6 years and this time i am hoping someone can help because i dont know what to do now.

- i do not know why it keeps adding the same comment over and over again

Jul 27, 2009

- will do, ill tell u the results

Jul 27, 2009

- i think it may be the processor, oh well... guess im stuck with my old 1 ghz desktop till i get a new socket 775 processor

Jul 31, 2009

- i decided to try something i knew was stupid, using a high pressure water hose, spraying it down really good, then drying it with a hair dryer on high heat, i poped it into the tower chassis a day later (to let it dry i gave it a day) and powered it on, WITH OUT A PROBLEM IT POWERED ON, EVERY THING IS WORKING, IDE, USB, PS/2, FANS, SOUNDER, PCI, PCIE, ONBOARD AUDIO, ONBOARD VIDEO, ETC. i know i probaly caused a few problems that will arise later on but for the moment its a nice pc to use, but my thermeltake dual fan power supply makes a high pitched noise when the system is powered off, it does the same no matter what pc it is in, is that fixable because it is annoying?

430 watts should do it..strip it down to the very minimal you need to start it. Also make sure the processor is seated correctly and that you have used thermal paste.

- heres a good site that describes what is happening during boot

- did you strip it down to bare bones and then try it?
if still no go..if you have replacement parts..start replacing whats left one at a time until it boots..if you have put all those parts onto another board and have the same problem..one of them is the culprit to be sure!

- well you stated that it was made up from parts "you had laying around"..so the integrity of any of the parts could be in question. Like I said, strip it down to bare bones,try it, if no go, replace the parts one at a time..leave the processor last since you don't have another..eliminate all the variables!
