PSU Modecom 620W (http://www.itbankeurope.com/info.php?part_number=MC+620...). When I was upgraded RAM PC worked fine and after ~2 months starting PC it shows black screen something about BIOS error, but after restarting PC starts normally. After some time it happens more. And there joins new problem. Blue screen with error dump. So I was clear CMOS and after then PC works fine, but some minutes till blue screen. I think maybe it was faulty BIOS and I changed BIOS to new one. Mysterious problem still exist. I was check RAM modules every is good condition. PC work with 1GB RAM in any slot or 2GB in free slot between, but PC don't start normally. After first start boots black screen with blinking underscore in left top of screen and after restarting PC starts normally. With 4GB RAM POST code is 0.4. an 3GB and 2GB modules near-50. and another number was something about "start USB initializing". Faulty BIOS I was try to upgrade with newer soft, but Abit home page BIOS software don't exist anymore and google too. What kind of a mysterious problem it is? Can somebody help?
