The past couple of days, my desktop computer (HP Pavilion m7350) will load up, then the monitor blacks out and the tower beeps a continuous beep, until I shut it down. A couple of times, when I restarted (after unplugging, hitting power button, then let it sit for about an hour or so) I get a message that there is new hardware ( I have NOT added anything) and tries to update, or whatever, a mulitmedia video controller. If I go through the steps, it cannot fix it, then will shut down, and beep...One time I was able to check the device manager and there is a yellow exclamation mark in front of that device...tried to do a troubleshoot, and the computer shut down and beeped.. About 4-6 weeks ago, I replaced the cable to my monitor, because the monitor was shutting down then..it seemed to work fine until yesterday!! Please help me...this laptop that I am using sucks!!! (although it is better than my pc at this moment!!) Thanks in advance!!
