Hello there,

I have this problem with my pc and im almost going mad...

2 days ago i was minding my own bussiness when suddenly my pc restarted itself. It loaded up Windows and everything went fine till the end of my session. Yesterday, same thing happened out of nowhere as the day before, pc restarted itself but this time as soon as it loaded up windows it restarted itself again. Then after the 2nd restart it wouldn't load up anything, it just stayed like that with a black screen but everything was powered up (dvd, cd-rom, the fans etc). I had to manually shut it down using the on/off button. Then i let it cool for about 2 mins (i thought it might have been some overheating that had caused all that) and powered it up again. It worked with no problem untill the end of my session. And finally today the big hit. It did the same thing, restart and worked for about 2-3 hours when again it restarted itself but this time it went to that state i described above where i got a black screen, everything has power but nothing happens, it won't even go the first steps (detecting ram, processor, cd etc). And to this moment it still is like that. Oh now i cannot shut it down using the power button as i did yesterday, if i keep it pressed long enough, it just restarts the system and stops exactly as before (black screen - although i forgot to mention that monitor says "no input signal from input A" or smth like that - usually i know u get that if monitor was plugged in and turned on before the pc and the message dissapears as soon as the pc starts) so I have to switch it off using the power button located on the power supply. Also the restart button does not work when the pc is in that state.

I saw that everything receives power (the led fans, dvd, cd-rom, processor cooler, even hdd i could feel some small movement, usb ports too, i connected my ipod to one of them and i saw it turns on when i do that but it does not recharge itself, so there is power on the usb ports too imo). I tried unplugging all cables as i said, no success. Oh and psu didnt seem to be too hot, neither anything else. No burn smell aswell.

My system specs:
p4, 3.4 ghz (socket 775)
1gb ddram (2x512 Apacer/infineon PC 3200)
HDD 200gb Maxtor
motherboard: asus p5gd1
psu: Aeropower II 450 W
OS: Windows xp home SP2

PC has 1 year and 4 months...

Im using microsoft antispyware beta and avg as protection but (shame on me) the last scan was done quite a while ago (but i rarely found spyware and i cant recall the last time i had a virus). Altho avg was always active. Also i never did a defrag on my HDD or reinstalled windows since i bought the pc.

Now im gonna go try and start it up again, maybe it works. And if it loads up Windows, what do u suggest i should do while im in?

----------------------------

I have searched all over the net for something similar but i couldnt find smth exactly as my problem. PLEASE HELP ME, im desperate as untill monday i have to finish my 3d project to be graded ((

sry for the huge post, wanted to give u as much details as possible, thx in advance guys.

In Windows you could change this setting to try to get errors:

rt. click My Computer then click Properties then Advanced then Startup and Recovery Settings then unclick Automatically restart

Also: look in your Event viewer: rt. click My Computer then click Manage then Event Viewer.
Or: Administrative Tools/Event Viewer or Start/Run/ eventvwr
Open the system as well as the application tabs & look for X errors. Click error line for details.
Post back the source & event id & Description especially of errors that seem to coincide with this issue.
Also check the Information lines that might coincide with this issue.

This sounds like a hardware issue to me tho. 1 year & 4 months? Is the warranty still valid?

You could try a new BIOS posted below. Sounds more like a PSU issue. Although there is power there may be some voltage irregularities etc.

Other suspects would be RAM; CPU; Graphics Card; Motherboard herself

Try removing one stick of RAM. Feel the air coming off the CPU fan: does it get noticeably warm? Do you have another Graphics Card to try?
