Pc Keeps Rebooting

[bobgo2627]

OK I have a PC here that used to be an old HP 6450 or something like that. I took it out of the case it was in and put it into a new case. I then put a new HD into the PC and started it up to install linux. Now when it gets through the BIOS Post, it get to the linux start up screen. Then I hit enter to start setup and it starts briefly and then reboots. It does it every time. Windows is the same exact way.

I thought it might be the CD-Rom so I changed it with a newer one I have here and same results. I then tried a different HD, same results. What is the freaking deal?

Some people have suggested testing the memory. I am running a memory testers and every thing is checking out fine after 2 passes. SO I guess that everything is fine and we are back to the mobo or so it seems.

Well here is a wacky deal. I ran the HD tools CD all night to zero fill the drive again, and that ran all night with no errors or anything. I did not get any of these washers for the brass studs, but I know that you some times need them. The PS is a 300 Watt PS and is much more than what was in the orginal.

I am going to try and yank one of the sticks of ram and try it then. If it boots then we know where the problem lies. If not I will try pulling the other and so forth. If both sticks are bad, then I am up a creek with out a paddle.

I will try the washers but I am not sure those are needed but hey anything helps

Have you tested the PSU?

Is the CPU fan running?

It looks like it might be a heat issue

I assume that you are trying to install from CD

If the box gets thru the POST without problems, then

I would suspect the CD drive or the cables.....are they all

seated tight?

I would also test the memory as there could be a problem there.

Please keep us all up to date as to what you try and especially when

it's fixed. There should be some valuable lessons here for all of us.

Good luck!!

try it in safe mode and see if you get the same results

if it dosent reboot in safe mode then you have a component problem

maybe videocard or incompatable ram

if you go to

control panel sys -advanced -start and revovery

uncheck automatic start ups make sure all the other boxes are checked.

then try starting your compt

if it is hardware you may get a blue screen

post back

OK here is what has happened. I ran mem test and after 4 tests memory is fine and dandy.

I ran Maxtors drive untilities and all is well with the drive.

I tested the PS and it tests fine too.

So the last thing is the Mobo or CPU. This is an old AMD 333 Mhz CPU board. If it does not work oh well. BTW, I tried a different CD-ROM, no dice. I changed the cables around, no dice.

their is a chnace your powersupply is testing "ok" with a tester, but is still faulty. If possible I would try and swap it out for a different one. Deafgirl mentioned that heat may be a problem, install a utility like everest to watch the temps.

Those old HPs were fussy with memory. I would check to make sure it doesn't require ECC/Registered and/or unbuffered.

OK the PS is not bad as I have tried it with other PCs here and it all still works fine here. So then I ran memtester on it and everything was and still is fine. Heat issues could not be since it is just starting up so I doubt it could get that hot that fast. Well I am just going to junk the PC since I was going to use it for another server here but oh well. If anyone has an old mobo and CPU that they do not need that take 168 Pin DIMMS PC100 or PC133 let me know.

If I could get anything running I would check these things but I am not getting anywhere.
