running whit gforce 8800 gtx.
screen text flickers a bit in startup window before windows turns on. it also has small dots of green all over the scren. Windows will not load unless i runn savemode. and when windows is loaded in safemode the screnn has red stripes all over from topp to bottom. What i did was deactivate the gforce, then reboot. all the errors are the same here, except now windows loads in normal startup. now runing on standard vga and still there are red stripes on the screen. tested all fans and they work.

This is more than likely an issue with the monitors themselves. Does this happen on the main monitor is you move the secondary cable over to it? What kind of monitors are you using, how old are they, and do you know the refresh rates on them?
Your monitor has a 3 year warranty through Samsung. The issues you are having indicate that your video control board in the monitor is beginning to have issues. You need to get an RMA to have it serviced before the warranty runs out.

This certainly sounds like the card is over heating, 120 celcius is way to high for the card to be working as mine is the 8800 GTX and runs at 60 celcius at the most. The blue screen just confirms this further as windows will do that to stop it from getting too hot. I would make sure that the fan is working properly on the card and if it has dust in it or anything like that then remove it and try again.
It sounds like you have a monitor with a common problem. After a few years some LCD monitorswill blow a power supply. The problem is caused by parts calledcapacitors overheating in the confined space of the monitor. If you aregood at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should workfine.We just posted a repair guide showing how to remove the case ansreplace the parts. The capacitors do need to be installed with thecorrect + and -connections, note the stripe on the old one and insert the new one thesame way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.
I hope this helps, if so please rate my solution.

White screen is an indication of a faulty video board.
A blown fuse in the actual screen will cause the same effect but usually these do not reset on a fresh startup.
You can check the ribbon going from the video board to the back of the
screen to see if it is somehow working loose, but I think based on your
description that this isn't the problem.
Check with www.lcdrepair.net if you want a repair. Something is wrong with your LCD controller and or GUI interface circuit or the circuit supplying power to it. If your technically endowed, you may want to open the monitor case and clean the dust and lint from around the circuits using a Small paint brush to sweep away any built up dust. These circuits take the Signal from the computer and controls the 2.5 million pixels on the LCD screen. Dsut can cause major problems with handling all that data. Give it a shot, what do you have to loose, its not dangerous if the monitor is unplugged.
