hello everyone, i really need help with my old computer. everyday when i start my computer up for the first time, it turns on, but it doesn't boot up. there is no "beep" sound to indicate that it boots up. it just turns on, and all i can hear is the cpu fan spinning at high speeds.. here is the video: http://www.youtube.com/watch?v=-5UrDw23CnQ and usually what i do is just let it run like that, then after like 5-10 minutes, ill hold down the power button to shut it down, then turn it back on, and then it will boot up.. (just like right now, i'm using that computer to write this) but sometimes, this happens: http://www.youtube.com/watch?v=LygXF-9Wsjc i've had this issue for a couple of months now but i ignored it since it happens very rarely, but it now happens everyday. i just changed my pc case a week ago. since i needed to clean everything up after 4 years. this is an acer aspire m5711. i really need to know if the issue is the RAM, PSU, processor, or the motherboard. my pc specs are: intel core 2 duo e7300 2.66ghz 4GB ddr2 ram nvidia GT630 motherboard is Acer FMCP7AM psu is 400W (acer default) i'm willing to buy a new motherboard and PSU to "restore" some life to this computer, as i'm planning to give it to my 5 year old daughter as her first rig. but a core 2 duo processor, i dont think so. so hopefully it's not the processor nor RAM. thanks in advance for your time. cheers!
