Hi, I'm new to these forums. I'm having a bit of trouble with my computer at the moment. Since installing a new graphics card (Gigabyte GTX 460 1GB OC, replacing an MSI 4670 512MB), I have been having a problem powering on my system. Sometimes I have to press the power button 3 or 4 times before it starts.
My System is:
Gigabyte MA770-US3 rev.1
AMD Athlon X2 7750 Black Edition
2x2 GB Kingston DDR2-800 RAM
Western Digital Caviar Green 808.88GB HD
Antec Two Hundred Case w/ 4 fans
Great Wall 700W power supply
Two optical drives
Unfortunately, I can't get a spare. Something else that I didn't mention previously is that when the system finally powered up successfully, a message popped up saying along the lines of "BIOS checksum error", and the system started restoring the primary BIOS data from the secondary BIOS. Would that have anything to do with it? Should I maybe flash the BIOS with an updated version?
Also, once the system is running, I don't have any problems.
Yeah go ahead and flash a new BIOS in it might fix the problem. Did you connect the PCI-e power cables because the 4650 wouldn't require it but the 460 would. This reminds me on the power supply how many watts is the 12v rail rated to carry safely?
I flashed the BIOS, but when the problem started occurring again, the BIOS Checksum Error popped up again on boot, and the backup bios overwrote the primary bios with the older version. I opened up the computer, disconnected everything, connected everything again, and the problems still occurred.
