Hi, I'm new to this forum so I hope this is the correct place for my issue.
I have a 4 year old computer with a Athlon64 4200+, Nvidia 7950GT Pci-E card and WinXP that has run games very well with at 1280x1024 on my lcd monitor.
A year ago I bought a Fw900 crt monitor with 1920x1200 and happily gamed on.
But six months ago the monitor began turning off randomly- funny thing is that the computer was still running...
Just 'no signal input' and an orange button.
So I restarted the computer - no biggie. I tried to switch the monitors, but the same happened on both of them.
However, recently in BOOTING, not necessarily after a monitor-blackout, the bios-post and screen with the green windows-loading bar are covered by short, horizontal green or red lines stacked on each other in 4 vertical lines. After that, a lot of thick white horizontal lines appear, and then the monitor turns off while the computer seems to continue booting.
I soon found out that by booting in 'safe mode' with the minimum drivers after a blackout, the computer would boot and run fine. NOTE: When reading the drivers on safe booting there are red lines on the screen.
Then I could restart in 'normal mode' with the newest nvidia drivers until the blackout occurred again. Therefore it seems to be a software, rather than hardware, related error.
However in GAMING, even with my old, tiny lcd monitor the graphic card now heats up to 100+ degrees C which causes red dots on the screen. Within two minutes the monitor turns off. Years back I did notice that the gpu was running very hot, but it didn't cause any problems... This is supposedly my graphic card dying after the use of a higher resolution and insufficient cooling.
BUT! Within the last month the monitor has been more frequent in blackouts - for example when I was updating Adobe flashplayer. When it reached 100% and I could press done, the monitor turned off.
And it keeps getting worse and more mysterious. Today I was playing/streaming a music track on a webpage and halfway through the track, the monitor turned off :-/
Well, instead of just rebooting instantly I let it play (the music was still playing) and pressed F4 to try and shutdown the webpage, but the music and the blank screen lived on. Funny thing is that when the track was over, the monitor turned on and the webpage was gone!
The windows log states no problems except a warning about a mouse driver, but the blackouts are getting more and more frequent and random.
I know it is a lot of information and that I probably should just get a new computer, but I don't see why I should if I can fix the random blackouts and live without gaming.
I sure hope someone can help/point me in a direction.
