Memory_Management BSOD

These old drivers below may have caused the issue

Remove any Adaptec Software since it is too outdated(1999) to be used in Windows 7

Code:

ASPI32.SYS        0x8e8bc000    0x8e8bfe40    0x00003e40    0x37d99842    11/09/1999 03:46:10

Sonic CD/DVD driver (used by many different CD/DVD programs)
Please update it or remove the application (burning program?)

Code:

PxHelp20.sys        0x83ba7000    0x83babe20    0x00004e20    0x42000f7e    02/02/2005 03:23:42

Update your ZTE Incorporated USB Modem/Serial Device Driver

Code:

ZTEusbmdm6k.sys        0x93796000    0x937af600    0x00019600    0x48084831    18/04/2008 11:05:21                
ZTEusbnmea.sys        0x9377c000    0x93795600    0x00019600    0x48084831    18/04/2008 11:05:21                
ZTEusbser6k.sys        0x93762000    0x9377b600    0x00019600    0x48084831    18/04/2008 11:05:21

I don't recall installing any Adaptec software in my PC, in fact I don't even know what it is. Is there any way to locate it?

And about that CD/DVD driver, maybe it has something to do with this?:

EDIT: and I also want to mention that my RAM usage has been quite unusual lately. Like right now for instance, I'm only running Google Chrome but my PC uses 85% RAM already. Is it normal, considering I only have 1 gb RAM installed?

BUMP! Just had another BSOD. This time it says PFN_LIST_CORRUPT

my PC uses 85% RAM already. Is it normal, considering I only have 1 gb RAM installed?

1GB is the bare minimum RAM for Windows7, 2GB+ is recommended for a smooth performance

The debugger cannot load the dump file properly, is this a genuine version of Windows 7?

Update your Network/Lan drivers

The only network device that I'm using is the ZTE USB modem, which I just updated earlier.

The USB modem driver is still oudated and is 3 years old, there is a strong possibility that it is the cause of this issue, the driver hasn't even been updated for Windows 7

I don't know, I've been using this USB modem for some time now and I only had this problem today. :/

Bump

Unplug that USB modem and try to replicate the issue, this will help us identify if it is the cause
