PC runs ok on 1ram,crashes when 2 fitted Closed

Question

Hi,
I have a quad drive Acer Veriton, running windows 7 with 4gb ram. Pc runs ok for ever with one 2gb strip of ram in place. If I change slots it still runs ok.If I fit the 2nd strip of ram, after a short while it gets BSOD and crashes. I have checked both ram strips, also used air cleaner to clean ram slots and heat sinc. After cleaning heat sinc it ran for a few hours then crashed. Acer want to charge me big money to even look at it... Need help please guys......

Did your pc come with 4Gb ram or it was upgraded to 4 Gb by you?if so then have you checked the Ram frequency if they both match in case you upgraded?The possible reasons are :

*Frequency match,
*or you system does not support up to 4Gb,please provide additional information with the issue,

The pc was as per the original configuration and has run perfectly well for over a year until recently. I only found that it wud run on one ram strip after I tried various eliminations, including checking drivers and replacing suspect external usb hub.....

I sincely think that one of the RAM stick is out order. Better buy another one.  

By the way here are some related tips:  
*test RAM reliability  
*Choosing your RAM  
*Why Windows is not detecting the 4 GB of RAM installed?
