Need some advice and or help. I have a computer that for the last few weeks or even months, was acting funny. It would fail to boot on the first attempt. I was able to turn off the main power supply and manual "force" it to try and try again until it finally would come alive. I assumed it was the HD and ordered one. I plugged it in today and after one start up it appeared normal and wanted to partion the drive before install win me. The system shut down and now it won't do anything. When I power on, the system turns on, HD and A drive lights flash, spin up, intro beep is heard, but that is it. To be sure the wasn't the video card or monitor, I hit key stokes on the keyboard to see if I could see or hear the HD spin up or anything, but nothing. If I let it set awhile, I can sometimes get it to try again and seems to work "once" IS my CPU fried? I double checked my CPU fans, they work. I removed the fans and vent and air sprayed them clean, reinstalled and still nothing. Any ideas? Thanks everyone!! Also, I just remeber something. I was losing USB ports too. My internet is from our cable unit via a USB port, and my digital camera uses one as well. Sometimes after using the camera, I would find my internet was gone. So I would unplug my USB and plug it back in. SOmetimes this worked, sometimes, not. So I would have to switch to a different USB port or restart. grrrrrrrrrrrr!!
