Hey folks, read a helpful post about getting memory dump files analyzed... been experiencing multiple crashes on start ups/randomly... once my computer gets running it's rare for it to happen... I've noticed it happens when my computer idles/goes to sleep, when I wake it up the screen is scrambled and then it goes right to a blue screen. Then upon start up, it'll blue screen, and unless i restore my computer it never makes it past the start up screen.

I have an ACER AM3100-U3202A desktop... not sure what specs you guys want me to post but if you need any more details please ask.

Also, this is the only memory dump file, but i have at least 10 minidump files... if those would help let me know.

Here's the dump analysis:

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arg1: 00000000, memory referenced
Arg2: 0000001b, IRQL
Arg3: 00000001, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 826ff715, address which referenced memory

EDIT: Also, don't know if it's related but every time I restart I have to reselect my wireless router's driver.. I never have to reinstall it but I always have to go into device manager and select it... sometimes when I do that my computer crashes also. I use a Linksys Wireless-G model WUSB54G.

rt2500usb.sys file listed in your dump file as the crash culprit is a part of your Linksys wireless card driver.
Try to reinstall driver.
If it doesn't help, most likely, you need new adapter.
