from last 2 weeks my computer was booting almost after 30 seconds. Before 3 months ago, my computer hardware assistant had removed graphics card because of heating problem(as he said).

Before 2 days ago when i was working on PC, approximately after 20 minutes it started showing the same screen. I thought that it might be monitor problem and then i started connecting to PC with the laptop via homegroup and i was not able to connect because it was not functioning. Now last 2 days i am not able to start PC because its not booting. Any specific reason.

I have following hardware

AMD altlon x2 (6400)
500 + 500 GB Harddisk
Asus M3N-78EM motherboard

Motherboard has nvidia 8300 In-built graphics card and Before 3 months i removed nvidia 8400 GS. I used to run both in hybrid SLI.

I am using windows 7 home basic genuine version + Kaspersky Internet Security 2012 and i update both thing regularly.

This is my dropbox url to the image

You need to remove all devices one a a time (or remove all and add them back one at a time) until you see which module it is / isn't faulting.

When you say it doesn't boot, does this mean the fans stop as well or you just get nothing on screen?

fans are running but blank screen, the beep sound is not coming when its start – KuKu Jul 23 '12 at 10:06
This means the PSU and CPU are likely to be OK. Are you using your onboard graphic card now? I had a very similar issue to what you're describing, taking out the battery on the motherboard for literally 2 minutes and then putting it back allowed it to boot up. – Dave Jul 23 '12 at 10:13
I am not using graphics card now. Means external one. Motherboard has inbuilt graphics card. I will try and lets see what happens.! – KuKu Jul 23 '12 at 10:21
wow..! got the time in this weekend and worked. – KuKu Jul 31 '12 at 5:45

I would think that you have a hardware problem. You'd better take it to a computer service center.

One simple way to confirm is to just load up a Linux live CD (or USB). Get the latest version of Ubuntu and see if it boots up (do NOT install Linux!). If it does, then good - you do not appear to have a hardware problem. Otherwise, you might want to get your warranty card ready.
