Hello, well yesterday while i was using my computer, after i restarted i got a problem. It starts post screen and freezes. Not always on same place. Usualy, when i turn it on here goes beep, like always and then post screen. Sometimes it stop on detecting processor, sometimes ram or it does not show post screen at all.I tried everything, including reconecting hdd, processor, ram memory... but it wont change.If system req matters, here: intel pentium 2.80ghz 2x512mb kingston ram memory 400mhz (-256mb shared memory for integrated gpu) motherboard e210882. oh yeah, my computer usualy heats even after it got some coolers on it, yesterday i was playing "Half-Life 2 Episode Two" and i usualy got crash and blue screen on that game. Thats why i restarted. Snd one more thing, usualy while my computer worked when i start windows, and some game (for example counter strike source) i got good 60fps but after some time playing it starts loosing fps, thats probably because of overheating right?
