Thanks again for all these responses. I had updated my bios, a while back. Taking your advice I reset it. However the random restarting still occurs.

My Fan Power Supply though...how do I check the fan speed on that puppy? It seems to be okay. I just bought a new power strip a Belkin UPS one. However the restarting yet again occurs. However after one particular restart I got that windows has recovered froma serious error window. So I sent the error report away and I got some interesting info back. I will post the screens of them. Please take a look. This is really starting to **** me off, as it renders my computer useless. However thanks for all your tips and help. I am learning a lot in the process, and by systematically testing each component like this I am bound to find the gimpy piece that is doing this.

Thanks to everyone thus far that has helped! If anyone else has any other ideas, you have a very attentive audiance right here!

Here is an interesting one. This one reports a CPU problem. Again according to all my temperature devices everything is running cool. Processor is currently 40c. System Zone 1 - 36c.System Zone 2 - 38c. Have no idea where those zones are located at however I do not believe my processor ever got hotter than 50 maybe 55. and zone 1 is never very hot. Zone two gets round 50 normally. I wish the intel active monitor told me where these zones are. My front port device also reports a 40c for my CPU. I also got another error about my memory. Sorry I did not get a screen about that. However, if you read earlier, I ran memory tests for about 24 hours and nothing showed.

And here is the last one. All three of these errors came at once after the restart. Now I just had my card checked by ATI and it came back clean. nothing wrong fully functional. So it is a little weird that I should get this problem.

I would appear the restarting has stopped since I did a reinstall. Funny this is after I reienstalled it restarted once or twice (right after) and it restarted once during the install itself! Yikes. But it hasn't done it in weeks! I guess this would be case solved, but it just doesnt feel solved does it?

Well just a half an hour ago, my computer turned off. There was a popping sound and a sulferish smell. I freaked out. I smelled and found out it was coming from my power supply. Obviously when I tried to power the computer on nothing happened. So I swapped that one out, the 420 watt one. And put in a 350 watt one. Here is to that one doing better! I hope this was the reason I had the random restarts!

Interesting saga mate. What brand was the power supply concerned? Was it one included with the case?

Case and power supply unit quality is a factor often overlooked by people who assemble their own systems, and your experience sounds like a handy example to others, mate.

Indeed! Buyer beware! What started as a software problem looked like it turned into a hardware problem! I bought the case because it was $40 with a 420 watt power supply, as for the brand of the case it does not specify! The power supply is an Okia brand...i never heard of it. However, I notcied when replacing it with the 350 watt powersupply, that the 350 weighs MORE than the 420. I am not sure if this means better though.

Yes, people should beware of cheap case/power supply combinations! In almost every instance, the power delivered will vary in its voltage levels, in most instances the voltage levels will be below the level required, and in far too many instances the cooling fans included with the power unit will fail after a relatively short period of time.

In the long run, it's more economic even, perhaps, to pay the extra and get a decent quality case and power supply unit from quality manufacturers such as Antec or ThermalTake

Yea, i have this same problem. But i had a virus. Reformatted to get it clean, and i'm getting the random restarts now. Im going to get a new powerstrip and see if that works. I'll be pissed if i tore my PC appart, and test my temps and everything 50,000 times just to find out its my powerstrip,lol. Thxs for all the info guys.

hi, I also have the same problem, a random computer restart. The funny thing is that I can work on the computer through remote desktop, without any restart. If I leave the computer on, with a downloading program running, but logged in through remote desktop, never on the computer, because if I try to log in it restarts, the computer stays allways on. Any suggestions?? thanks
