Computer only starts sometimes

December 16, 2007 at 09:46:06
Specs: Win XP Pro SP2, AMD Athlon 64 3500+ 2.2gh

Hi, my computer has not been starting up lately. Whe i turn it on, all the fans go on and all the lights go on, but nothing happens, all i get on the monitor is "no signal".

However, if i leave it for say 10 - 20 mins it will eventually boot up and load windows.

I have replaced the hard drive, checked all cables etc but to no avail.

My Spec is as follows:
AMD Athlon 64 3500+ (2.2ghz)
1gb Ram (2 x 512 crosshair)
Asus A8V Motherboard
Geforce 6600 graphics card

Any ideas?

I would say it is a failing power supply. There doesn't seem enough power to run your PC and thus the long loading time.

1- Do you get any blue screens?
2- Does the PC crash after awhile?
3- What happens if you boot up and tap the F8 key and try safe mode?
4- Does it load up right away?

1. No blue screens.
2. PC does NOT crash after a while.
3. I will only be able to boot it up in safe mode once it eventually boots up properly and i have started it in safe mode before and it works fine.
4. once its starts to boot up it loads straight away.

Th only problem is the initial powering up after i have completely turned it off.

It all stats and loads fine if i wait for a while, but i cant do this every time i want to turn the comp on. I need it to boot up staright away.

Cheers

Another note, my comp usually makes a few beeps when it starts up, and now it doesnt make these beeps, so this is how i know that it is not actually booting up.

I also tried taking out the kettle lead that powers my monitor from my PC, and then turning the comp on, and if i heard the beeps i then plugged this back in and it all worked fine.

all i get on the monitor is "no signal".

I would try reseating the video card.
Sound like the bios hasn't post and may be stopped at the video.

Have you throughly cleaned the inside of the Central Processing Unit Tower especially the CPU cooler as eccessive dust build upon this component cand cause reduced reliability.

Use compressed air to clean. No vacuum cleaners.

It seems the power supply is faulty. You indicate the PSU has an outlet that provides power to the monitor, and if you unplug the monitor power cable from this before bootup the problem goes away.
You should replace the PSU or failing that, use a different power cable for the monitor to plug it direct into mains instead of the PC.
If it were mine, I would do both. Get a new PSU and a new power cable for the monitor so it isn't drawing power from the PC.

I used to have a signature but it disappeared and I just couldn't be bothered writing another so please feel free to ingore this.

1)GO TO BIOS->select VGA/OR SVGA MODE WHICH is suitable to u
2)go to safe mode->check the vga resolution set it to normal,not to high
if these dont work, try to connect your CPU to other monitor,check if everything goes fine? let me know once u did these.or in your boot.ini add /basevideo.do let me know

venky
