Ok, I have an Computer using Windows xp, every time i start up, it restarts itselfs, even in BIOS, the memory and Video card are reading, and it does not seem the Processor is overheating, the processor is an AMD 2700+.
Any ideas on what is going on??
 
It could be possible over-heating, have you checked your heatsink recently to make sure it is "functioning" correctly, and is all cloged with dust, Make sure the fan is working. If you notice your system is loaded with dust, take the time, clean it out, then try again, and that might solve your problems.

Maybe Bad RAM? (Not sure on this one...)
 
Heatsink is fine, checked all that stuff, i bet its the processor overheating, but still working on some stuff.
 
Are you sure the fan on top is working ? if you think the proc's overheating then get some extra case fans blowing on it temporarily to see if that fixes the problem.
 
i have all the fans working, plus a floor fan blowing on the Processor, i think the Motherboard might be doing it, or the processor going bad,... but everying i do does not help
 
I've had a heatsink with a little burr formed from hardened Arctic silver compound and it wouldn't sit flat and I had restarting problems. Lapped the heatsink and cleaned the cpu with acetone and carefuly assembled everything, making sure it was flat and it fixed it.
Hope this helps.
 
I was working with the guys last night. The processor acted alot like it was overheating. Unfortunately, the motherboard had no temperature sensors (that we know of) to look at in the BIOS.

We switched the stock AMD cooler to an SLK All copper thing. I forget the model. I noticed that the AMD cooler came with a MASSIVE amount of cooling paste. There were no materials around to properly clean the CPU off, but we use QTips, and managed to get the core clean at least. I dabbed a TINY bit of Arctic Silver on, and put on the new cooler.

However, before putting the new cooler on, I spent some time trying to clean it off, and noticed that it seemed like some Arctic silver, or something had hardened or burned onto the surface of it, right where the core goes. However, out of stupidity, or desparity, we put the the cooler on, thinking that it would still work MUCH better than stock, and at least help us diagnose a problem. The problem is still there tho.

What can we do to diagnose further? Is swapping the CPU's safe? If so, do we have to Clear the CMOS first? Thanks.
 
CMOS settings are easy to set anyway, so whenever my computer starts acting up, one of the first things I do is reset the CMOS (especially since I OC, resetting the CMOS underclocks my processor, so I don't have to take into account stuff like "multiplier too high, FSB too high")

Whenenver I get a problem that seems to elude me, I test each individual component with the minimum number of components needed in. (unplug CD drives, extra hard drives, pull not needed PCI cards out temporarily).

Since you seem pretty confident that you've already tackled the possiblity of your cooling not working, I would test the CPU next, as well as memory and motherboard.

If you have another XP processor available - or just one using a chipset your mobo supports - I would swap that in. If it does work, try testing your CPU on another system.

If the other processor doesn't works, then I would proceed to check the memory and motherboard. Borrow your friend's working RAM, and try the RAM in each slot (sometimes I've seen just a specific slot go bad). If your mobo has as a specific ram placement for DDR, make sure you follow those guidelines.

Also, although rare, make sure none of the connectors you have holding the motherboard to the case have metal parts touching. I have had a case in the past where my friend's machine kept rebooting randomly, and it turned out, after intensive testing of each individual part with my machine as the test bed, that a metal screw between the motherboard and case was shorting the system.
 
What all can we use to clean the Heat Sink and the CPU?
Will Rubbing Alcohol work, will just actone?
I think thats the problem, is it needs to be cleaned of all the crap buildup
 
Yes, standard rubbing alcohol + QTips will work. It all evaporates off too :)
 
Ok, We cleaned the CPU and the Heat Sink of all the Silver, and added a little to the clean heatsink and but it all back together, and it is still restarting, well overheating.... Any ideas on what we can do????
