A couple of weeks ago, I left my comp on to download stuff, and the power went out that morning. So, I came home to see my comp sitting at the verifying DMI pool data screen. I rebooted and found C: drive had been wiped out. So, I put my windows disk in and try to use chkdsk which gave me an error that it couldnt fix. Short story, it took me a while to get the XP install to format and reinstall windows. I get into windows and find out that my D: storage drive has also been wiped out. But E/F drive was fine, so I shut down the computer and unplugged it. I tried to format D: drive, but it wouldnt format, I finally tried Seagate's HD format program and it worked. Since then, I have had about 4 crashes, which seem to be random. While I was downloading a demo, when it was just sitting there, and after playing BF2 demo for an hour or so, it locked at the ready screen. Each time it crashed, it totally messed up the drive, and I had to reinstall windows.

One thing though, since the power went out, on bootup sometimes all of my drives arent detected. It will detect my main drive, but not D: or my dvd drive. I have to reboot a few times when this happends to get it to detect everything. C: and D: are on one cable, and E/F, dvd drive is on another, so that kind of rules out a bad cable.

I do not have another power supply to try.

Today, when I went to shut off my comp, instead of the normal XP shutdown boxes, I got a dropdown box, and when I restarted, windows was messed up. It would reboot at the XP boot screen, I ran chkdsk repair, and it would boot, but my desktop would stay black and nothing worked, so I ended up reinstalling again. Right now im running fine, but its only a matter of time before it messes up and I have to reinstall again.

At first I thought it was just my HD going bad, untill I noticed that all my devices werent being detected. I think it's either my power supply or motherboard, but im not sure which. And I want to make sure I know what is bad before I buy a new one, because I dont have enough to just start buying new parts. Sorry for the long post, hopefully someone can help me.

Voltage spikes can be a killer. As to your problem IDK but most strongly suggest
you buy & use a UPS w/AVR. Mine has saved me several times over 5 years.
A decent UPS will shut down a small network of unattended PCs safely.

I second this suggestion...IMO a UPS is a vital part for a well planned computer system. Im running a APC 1000VA UPS and it is fantastic. Never ever, ever any shut downs due to power loss, brown out, poorly conditioned line signals...nothing.

I never thought of using a UPS before. I will definatly have to get one. But I also need to find out whats wrong before I do.

I did watch the voltages with Abit's hardware monitor, and speedfan, and +3.3 and +5 didn't differ much, usually right on what they are supposed to be. The +12 goes from 11.86 down to 11.80, and sometimes 11.70. It's an enermax EG465p-VE. I have an ABIT IS7-E MB.

I would have replied sooner, but due to having charter as an ISP, I couldnt get online.
