Random freezes after new memory install
I have an HP dx5150 with Ubuntu 11.04. I recently added 2 new memory chips (total 4) with the same specifications as the originals. The memory is recognized by the BIOS and Memtest returns no errors. The computer boots normally and functions normally for an hour or so, and then freezes. When it freezes it does not accept any input and the screen gets displays a bunch of small green or purple lines. Here is the output from lshw:
I have also been able to use the new memory by itself without problems. Any ideas would be appreciated.Code:description: Desktop Computer product: HP dx5150 SFF (EW249UC#ABA) vendor: Hewlett-Packard serial: XXXXXXXXXX width: 64 bits capabilities: smbios-2.4 dmi-2.4
