It started about a month ago. I usually have my computer running all day and night going on standby when idle. I noticed that my computer was turning off on its own. Several days later i am on the computer and my monitor blinks out and comes back with a blue screen saying:
"A problem has been detected and Windows has been shut down...blah....blah..........
MACHINE_CHECK_EXCEPTION
Beginning dump of physical memory
Physical memory dump complete"
First time i had seen it. then throughout the next few weeks it was doing the same thing from time to time.
When i restart the computer, usually it boots up fine. Sometimes during boot up it stops and reads:
<Windows root>\system32\ntoskrnl.exe
and over time, occuring more frequently, when i turn my computer on it will not start. I see and hear all the fans working and dvd drives working, but my screen displays nothing. My computer wouldn't even beep.
I would resolve this by turning it off and back on. Now, since yesterday it will not start, no matter how many times i try.
This all started about a month ago. The only new things I have added in the past 2 months are a new Acer monitor and a Wacom Tablet.
I appreciate any help i can get since i need this computer for school.
I built the computer over 1.5 years ago. I use Windows XP SP2.
CPU: AMD Athlon 64 x2 2.2ghz
2GB DDR SDRAM
Asus ATX AMD Motherboard
Thx again for your help :)

Do you mean the computer won't power up or your computer won't boot into your o/s ?

Check you PSU (power supply unit) Per these instructions.

1) Unplug the leads to the case switch at the mobo and jumper them with a small piece of wire. Now turn on the main power switch at the back of the PSU. If nothing happens, we're a long way to proving the PSU is dead.
2) If above procedure caused nothing to happen, now we get a little more into it. Remove the 20pin PSU connector and the 4pin CPU connector to the mobo, all other psu connections can stay put. Using a small wire (a paper clip will do) jumper pins 14(the only green wire) and any BLACK wire (let's say pin 13 or 15) on the 20 pin PSU connector. Now turn on the main PSU switch. Your PSU should come to life (HDD spins up, and fans spin).
) If nothing still happens then start removing 4 pin molexs one at a time, starting with the video card (if it has one). This will eliminate any peripherals "holding" or "pulling" down the PSU. After all connections are removed and still nothing, then your PSU is dead for sure.
4) If after step 2, all fans spin up and HDD spins, but at step 1 nothing works, then it's most likely a faulty motherboard.

WTF was all that about?
You give instructions on how to test a faulty PSU(which are certainly not advisable for most people).
Then continue with "if nothing still happens".
Nothing still happens to what?
There is no power going to the motherboard so what is supposed to happen?
"After all connections are removed and still nothing, then your PSU is dead for sure."
Haahahhha
The OP has already said

when i turn my computer on it will not start. I see and hear all the fans working and dvd drives working, but my screen displays nothing.

Seems to suggest the PSU is at least semi functional dont you think?
Next time you copy and paste try to paste in a thread thats relevant.



Anyway,FlashFrame
Remove all unnecessary components from your pc(cd/dvd roms/sound cards ets.),leave the hard drive and 1 stick of memory.
If your pc has onboard video remove any other graphics card.
When you reboot tap F8 repeatedly and try to boot in safe mode.
Or keep tapping delete(under insert)to try to gain access to the BIOS.
If this fails switch to the other stick of memory and try to boot using only that stick.
Let me know if this works.

EDIT: Sorry replied to wrong thread.

1. Have you installed the Operating System?
2. Did you check the jumper settings?
