So I have this Acer Aspire AM1100-E1201A. Ive done everything in setup same as i have with any other comp ive done. This is about my 16th build so Ive done a few. Everything goes perfect upgrading it to windows 7 home prem with 4 gig ram. stock specs are windows vista premium 64 bit with 1 gig of ddr2 ram. after all needed updates i go to install to install a GC: ASUS 560 Ti. I go through normal install. boot up system image comes though card; windows boots, drivers install, system reboots windows loading screen and then BSOD.... so i wait a few minutes yup nothing ok. i shut down (hard off) n go back to MOBO graphics nothing no boot **** all. so hard off again pull the card and one more try, windowsx boots like normal i go to device manage everything is normal at first glance all is good just a quick look at the resources and there it is theres this PS/2 mouse that is showing error code 43(reboot system error code 10, another reboot back to err. 43) ok well first thing im using all usb mouse keyboard so no ps/2 even needed i check the properties for this "ghost" mouse and again error device was unable to start, is missing or not all drivers are installed . i check the resources and its running on irq 12 and windows has greyed out the check box to manage the irq manually. and aparently that is also the irq windows keeps trying to install my graphics card on ive tried about 6 different graphics cards all with same results. um ive also tried disabling the mouse in device manager but it still causes conflict same if i uninstall it after i reboot the system it just apeers back in the device manager resources view but never actually shows in the devices list unless i disable it. anyone got any ideas im stumped
