Unusual behavior at system startup (Gigabyte MB)
I having a strange problem with my PC. Every time I start up my computer it just simply refuses to start. Let me
explain what happens:
I press to power button and:
a) Everything begins to start, then I hear continuous "beeping" from the internal speaker. After 8-10 secs the pc
shuts down and restarts then the "beeping" again for about 10 secs. This happens about 5 times then finally the pc
starts to boot up BUT after that I get an error message that "MAIN BIOS CHECKSUM ERROR" so it starts to recover and
one more reboot then FINALLY the pc starts normally...
b) After pressing the power button nothing happens, after pressing multiple times (5-8x) the pc begins to start
then the point "a" (what I mentioned above) comes...
So every boot takes about 10 mins and its very very annoying...
What I've already tried:
- Replacing the BIOS battery with a brand new one
- Updating the BIOS
- Checking the font panel connectors on the Mobo. All of them are connected properly (Power switch, reset sw, etc..)
- Removing USB devices didn't help.
- I replaced the power supply even with a brand new one (320W)
If anyone knows a solution please tell me because my mind is just about to blow...
Motherboard: Gigabyte GA-G41MT-ES2L
CPU: Intel(R) Core(TM)2 Duo CPU E7400
RAM: 4GB DDR3
GPU: AMD Radeon R7 240 (Oland)
Power supply: Enermax EG475AX-VE(W) Noisetaker 320W
I hope someone with better knowledge can help me out
Thanks in advance

Please count, and tell us the number of beeps the computer produces when you try to boot up.
The power supply might be a little underpowered for your system. Make sure that your CPU fan is turning properly, and isn't clogged by dust.
From your motherboard manual:
What do the beeps emitted during the POST mean?
The following Award BIOS beep code descriptions may help you identify possible computer problems.
(For reference only.)
1 short: System boots successfully
2 short: CMOS setting error
1 long, 1 short: Memory or motherboard error
1 long, 2 short: Monitor or graphics card error
1 long, 3 short: Keyboard error
1 long, 9 short: BIOS ROM error
Continuous long beeps: Graphics card not inserted properly
Continuous short beeps: Power error

Indeed; if you have a power supply that is too low in voltage/wattage; then it will not have enough juice to power all of the components in your system. I would say that getting a psu with a bit more power than you need might be better than one with not enough power. Just dont get one thats overkill as doing that will jack up the ole electric bill and mr. electric man will be loving you lol.

Depending on the brand and quality of the PSU, most run most efficient at 60-70% of the max it can put out. By buying one larger than you need, it allows for future upgrades without having to buy another PSU, if the capacitors age and weaken a little, you still have enough to run your computer. No matter what size PSU you get, it will only pull from the wall what your computer is demanding. So, buying a larger one than you need makes good sense. The real thing about power supplies is do not ever skimp on a PSU. Buy a top quality power supply. They cost more but are worth it because they have all the safety protections where the cheap ones do not. A PSU is the heart of your system and runs everything you put in it. A cheap one can fail and take out everything in your system.
