I am using a windows xp PC and it was running fine, today I was away for a while and when I came back I could see a blue screen, So I have manually restarted the machine
and then I could see that while the boot screen came there were lines flashing(some thing similar to the attached login screen) and the machine hangs without loading OS.
And after several manual restarts I could reach the login screen and in the login screen (as in the attachment) flashing lines started to come and the PC hanged/freezes there.

So I kept restarting and un predictably machine stopped working in either while BIOS loading or When Login screen loading and sometimes it just started to automatically restart when loading OS.

At a point I tried to login into safe mode and stopped all the services and I could restart and login in the normal account use browsing for a while but again I got these lines and flashing screen and the PC hanged.

Now the PC behavior is totally unpredictable some times it's freezes before loading, sometimes it freezes at login screen and some times it doesn't show anything in the monitor (black screen), when ever PC hangs/freezes I can
see these flashing lines.


Please help me in this regard.

Thanks for the reply, again got blue screen just when I just visited the control panel... it might take some to restart successfully and login in to the PC, I will try to uninstall the drivers once I login.

Blue screen was saying BAD_POOL_CALLER

I have reinstalled the GPU drivers which doesn't resolve the issue.
Just now I have cleaned the mother board and cashing ( not sure whether it make a difference but I just cleaned everything ), I could login the system now, but not sure when I am going to encounter the same issue again. It usually comes all of a sudden.
Let me update the thread when I get it again.

I thing I was not sure is isolating the issue, whether it's a hardware fault (probably on-board VGA, power-supply, bios) or Windows issues (probably VGA drivers) . Further I have just noticed several USB ports not functioning properly yesterday when I used one of these ports through a extension cable to connect internet with a external USB dongle. And most of the time I was getting the flash lines issue most of the time and very frequently.
Today I have identified one USB port only which is working properly without any issues and using it, I have removed all other USB devices now.
But my guess on USB ports malfunction and flash lines(PC hang/freez) may be totally wrong.

Let me check little more and update the thread. Thanks for the suggestions so far.

Good point, I will keep an eye on it. After cleaning the board and cashing I didn't get the problem again, at the same time I didn't try to use all the USB port. I am selectively using 2 USB ports only.
