Right i've been out today and bought a Epson R300 but when I try to install it onto my pc it keeps crashing. I am using windows XP Home and a dell dimension 8000 pc. The error message i'm getting is: A problem has been detected and windows has been shutdaon to prevent damage to your computer. IRQL_NOT_LESS_OR_EQUAL If this is the first time you've seen this stop error screen, restart your computer. If the screen appears again follow these steps. Check to be sure you have adequate disc space. If a driver is identified in the stop message, disable the driver or check with the manufacturer for driver updates. Try changing video adaptors. Check with your hardware vendor for any BIOS updates. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable componants, restart your computer, press F8 to select advanced startup options and then select safe mode. Technical information: ***stop:0x0000008e (0x0000005,0x804e8b66,0xf7bbb9a4,0x00000000) Begining dump of physical memory Physical memory dump complete. Contact your systems administration or technical support group for further assistance. So there you have it i'm TOTALLY lost One thing I thought it may be is I am using the usb cable from the printer I have just connected A dell A920. Is that what it means when it says IRQL_NOT_LESS_OR_EQUAL Is the usb cable not up to the job??? Hope one of you techy heads out there can help. Cheers, Pete.
