|The message on the blue screen tells you what the problem is, then you have to figure out what needs to be done to fix it. Unfortunately you didn't provide that info. If you're just seeing a flash of the blue screen & then the system restarts, you should disable the auto-restart feature in Windows so that the blue screen is fully displayed. Then you will be able to properly troubleshoot the problem.|
It's unlikely updating the BIOS is going to help & if you do it incorrectly, it will be the end of your motherboard. That's not necessarily a bad thing because your board is crap, lol. There are a several possible causes of random restarts - power supply is failing, CPU is overheating, RAM is bad, etc.
There are different versions of the L4S5MG3 so you will have to know exactly which board you have. Scroll down to socket 478:
"but ram cards show harf of rams. ex: 1gb ram showing 512mb
i have change lot of rams.but same resualt"
Your board accepts a max of 1GB per slot of DDR333 (PC2700). If the density is wrong, it will only recognize 1/2 of the capacity. Did you test the RAM with memtest86 or memtest86+? If not, that's where you should start.
