Both hard drives are showing as enabled in device manager

Ok do tihs. Right click my computer, and click on manage, click on disk management instead of the device manger if it shows up in the disk management it might not be intialilized yet. If it is not right click on the hard drive that is in question, and click format or if there is a red little X through the disk right click on that X and intitialize it.

I though I had it sorted out. I used disk management to get the second hard drive problem sorted out. I checked the all the temperatures and they where all ok.

A few people on various help boards had suggested it may be the power supply and that 350w was not enough.

I went out and bought a new 500w power supply. I reformatted the PC and things were stable. However when doing windows SP2 update about three quarters of the way through the PC rebooted. When it went back into windows there were lots of problems.

Rather than trying a system restore I decided to another format. This time all windows updates installed ok and I was able to install all the programs I use. I was also able to install my AGP card, a satellite PCI card (I connect a satellite dish to a PCI card on my PC) and a TV capture card. I rebooted the PC a few times to make sure all was ok. I tried using various programs and connected to the internet. I was using my PC for about 6 hours with no problems. I then went to bed happy.

I work nights. I got up and had something to eat etc. Before I went to work I thought I would test the PC. I booted up the PC got into windows and the PC rebooted. The Pc rebooted again when it got back into windows. I then had to leave for work. I am now putting this on the help forums while I am in work.

Do think it is a problem with the processor. IT is a 2.2.Ghz Pentium 4 that is about 3 years old.

Apart from trying a different processor (which I don?t have) is there any way I can test the processor?

If your up to it, why not leave sp2 out of this for awhle. Format but dont update to sp2. There are just some poeple's pc'sthat do not like sp2. Its worth a try before running some torture test's on your cpu.

Well after all this time I finally found out it was the processor at fault. Thanks for everybody?s help

well wouldnt ya know it. the most expsensive part of the pc was at fault. Hope you get it all sorted out with a new cpu!
