We have 300 PC in our network which runs XP. The PC configuration as follows.
Asus (PC) Desktop Barebone
Intel(r) Celeron(r) CPU E1200 1.60 GHz
RAM 1 GB.
Due to budget constraint, I have upgrade these PCs only by adding another 2GB of Ram by investing £20 for each PC, so the total RAM is 3GB now.
I installed windows 7 32 bit and it successfully installed. On the device manager it was clean and it didn’t ask for any additional drivers. Only under other device I can see a alert with a yellow mark for a unknown device.
Only problem is if i leave the PC for 4hrs, the screen goes completely dark. Even if i move the mouse /tap the keyboard, the display doesn’t come and I have to restart the PC to see the screen again.
For testing , I installed a low profile graphics ATI Radeon 1GB DDR3 graphics card (R5450) and i left it overnight and when i moved the Mouse in the morning, the screen came up immediately.
So not sure if this PC on-board graphics is powerful enough to keep up the display for a long period.
Or that i need to do anything in the display properties and settings for the display to come up even it is left for long hours, without restarting.
Any help much appreciated.
