I am upgrading my emachine T3302 from a Sempron 3300 cpu to an Athlon 3400 cpu. When I installed the new chip I discharged myself to ground, and used new heatsink compound. When I boot my computer, windows starts up, my cpu fan increases in speed twice, and before all programs are loaded the PC shuts down. I found information suggesting I clear my CMOS memory and/or flash my BIOS. I cleared my CMOS, no help. So, I started looking for a BIOS upgrade or a BIOS flash utility, and can't find anything on emachine's site or gateway's either. Please help.
