So...this morning, I find that my computer is shut down, after having left it on last night. Strange...when I start it up, I get the CMOS prompt--and I go to the time and date settings (On the occasions when my computer has shut down in the past, the date/time are reset). However, on this occasion, the time and date are the same...which was confusing. It starts up without incident. However, about 2 1/2 hours later...the computer gets a blue screen and shuts down. When I try to start it backup, I get a motherboard error 7F. This doesn't seem like a coincidence, considering when I looked up the stop error code that I got on the blue screen, it was 0X0000007F. I looked up the stop error code on this computer to find out that it often had to do with a hardware problem, many times a RAM problem. So...I refigured the RAM in different slots...and this time, no motherboard error. BUT, i when starting up windows, I get the "one of your windows system configuration files is missing/corrupt. Put the windows CDROM in and press "r" in the setup to run repair." I put the CD in...nothing. I tried several different things. I played with the CMOS settings, thinking maybe the boot sequence was keeping it from working--no go. I'm not sure if the CDROM drive wasn't working (although, it definitely had power). I couldn't hear whether or not the CD was spinning successfully. After repeated attempts at changing things around and rebooting, the motherboard eventually stopped sending monitor signals. No luck. Again, I tried reworking a few things...and eventually something VERY strange happened. At one point, when I started the computer up again, the digital motherboard error display clicked audibly...and the number display lit up and died down repeatedly. In addition, the LED lights from the on/off display on the front of the computer and the LED lights on my motherboard would click on and off in sequence with the motherboard display...almost like the computer was trying to start up and couldn't. Now...it's just completely dead. I tried checking the motherboard battery...I took it out for a while, put it back in...still dead. I've removed all the RAM...still dead. I realize there's no easy fix here, haha. I'm just wondering what the problem is. Tonight, I realized that the reason the compute rshut down last night is because there was a power outage...so, I'm concerned that something fried multiple parts of my computer. Is it possible this is simply a problem with the power supply? Simply the motherboard? Or are there definitely multiple problems with different pieces of hardware?
