My Compaq Presario desktop with Windows7 professional installed becomes completely unresponsive once in 2-3 days, since I added an extra 2GB 667Mhz DDR2 ram to it. As told on the official hp site, my computer supports upto 4GB DDR2 ram. However the previously installed RAM was 533MHz & the new one is 667Mhz.
After hanging, nothing even the CTRL+ALT+DEL doesn't work. Just prior to hang, there is no slowing down of the computer, it just becomes instantly unresponsive.
Is that a RAM incompatibility issue?
My Computer model is : SG3745IL

3If you remove the new RAM stick, does the issue still occur? – soandos – 2012-01-09T05:45:27.780
