I have a Gateway GX7022E desktop and the cpu is dying. Gateway will not tell me which cpu I can upgrade to because its out of warranty. They keep telling me to call the $2.95 a minute # for the info that I need. The mobo is intel D945GBI frontside bus 1066 800 533. It has a pentium d 830 at the moment LGA 775 socket win xp sp3. I purchased an intel E7500 2.93GHZ dual core Wolfdale and it will not boot up. Is this cpu compatible with mu board. Any help would be greatly appreciated. Scottie Scruggs
