Hi that is the first thing i have tried and 3d mark runs fine also checked for any hardware conflicts and there are none

[phillpower2]

Under what circumstances is the monitor going into stand by mode, when it is in use and if so when gaming, whilst on the internet or office work etc or is it when it is left unattended?
What is the make and model of the psu, how old is it and have you got or can you loan a known good psu to try.

it may be a setting for power saving on the monitor itself

HI here is the link for the computer tower http://www.amazon.co...8376005&sr=1-14 ATX / Micro ATX Computer with 650w PSU Black & Silver

it has had a new mother board fitted and the graphic card is a g force 9600 gt

the moniter goes to stand by and the hard drive is still working tried a new monitor and cable same problem and 3d mark works also prim95 test done no softwae conflicts tried changing to new power surge extention lead and the adaptor for the monitor was checked also in power managerment monitor and tower set to never to go into stand by mode

states no signal imput check video cable

came up with same message with a new monitor and cable
the monitor can stay on from 25mins to over a hour and the monitor will not switch back on still states same message and only way to restart the monitor is to rebooot the system
checked for any over heating of fans but all seems ok can include a screen print if needed

I noticed in the photographs of your case that there is no case fan for extraction, also for the price you paid the quality of the psu is questionable I`m afraid 650W means nothing if it is unstable.
Download Speedfan from here http://www.almico.com/sfdownload.php run it and post a screenshot so your temps and voltages can be checked, the trouble with having no extraction is that the warm air inside the case is simply being moved around over your components, it could even be causing your Ram to heat up possibly leading to the issue you are having.

I believe the +12v rail on your psu may be your problem here but you may want to have happyrock or another Tech confirm this, if the +12v rail drops below 11.40v you can have all sorts of issues.

thanks i will let you know if the problem starts again

[phillpower2]

Thanks for the update and fingers crossed you do not have a recurrence.

[steveba]

got the same problem back again and what i did was from another website started task manager opened a new tab and put in explorer.exe and hit run the computer worked no problem for 7 to 8 hours till i shut it down

[steveba]

it was the geforce graphics card the motherboard fitted is a MICRO-STAR MS-7387 what would be the best graphics card to use with it mainly for gaming

Heres a decent budget card for you to look at http://www.novatech....ch/46701gb.html
There are better cards available but as you never stated a budget I kept the price low although this card will do what you require, have a look at the reviews.
