Attempted to increase performance beyond limits and the system malfunctioned.
Hello, this is my initial inquiry here.
The motherboard in question is a Gigabyte Motherboard
GA78LMT-USB3. It is running
AMD Athlon 2 X270 processor with 4 GB of RAM.
Windows 10 X64 if that matters.
Since this is the only system I have with overclocking support, I attempted to overclock the CPU. Here are the adjustments I made:
■ CPU Frequency increased from 200 Mhz to 300 Mhz
■ Adjusted the minimum voltage increment to around 0.010.
After saving the settings and restarting, the computer crashed during POST.
I restarted again and no longer saw a screen on the monitor.
Then I tried resetting the CMOS using jumper pins.
It worked—PC started successfully—but it reported a bad checksum and asked me to press a key to reset the BIOS. If not done, it would revert to the last known good configuration in 10 seconds.
Unfortunately, I didn’t have a keyboard plugged in at that time, which caused the BIOS to revert to LKGC.
Later, I attempted to reset the BIOS again using the jumper, but it didn’t help.
I know this PC is fairly old, but I really hope it gets back online.
Thank you for your assistance.
The AMD CPU frequency was set to 200mhz, but you went up to 300mhz, learn first then proceed. It's impressive you managed to run Windows 10 X64 on such outdated hardware. Try pulling the power from the wall, reset the BIOS using the CRTC (Clear Real Time Clock) with the motherboard battery removed, reset the jumper back to the run configuration, reinstall the battery, ensure the keyboard and mouse are connected, then plug in the power and attempt to boot again. When the machine starts, hold down the delete key—sometimes F1 is needed to access the BIOS menu, where you must adjust the Date and Time settings because your data was lost.
I might attempt to remove the watch battery, disconnect it from the power source, wait for half an hour, then reinstall it and check.
The AMD CPU frequency is 200mhz, but you went too high with 300mhz. Learn first before trying again, okay.
I was surprised you managed to run Windows 10 X64 on such outdated hardware.
Turn off the power completely, reset the BIOS using the CRTC (Clear Real Time Clock) pins, remove the motherboard battery, set the jumper back to the run configuration, reinstall the battery, ensure your keyboard and mouse are connected, plug in the wall power, and try booting again.
While booting, hold down the delete key—sometimes F1 is needed too, as it indicates the BIOS prompt. You need to adjust the Date and Time in the BIOS because you cleared the CMOS. After that, set it to (Optimized Defaults), then exit by pressing F10 to save and exit. That should work.
