Boot Loop. Cant do anything

Hi guys.

I recently changed the HDD of my old comp as i needed that in the new comp.

I added to the old one a 160 GB hdd seagate .

i tried to format it wit win 7 and i encountered a boot loop.

it says windows is loading files and than restart when the logo apears.

When i get into safe mode with a pre installed win in the hdd still does boot loop.

Even in the start up repair area.

I reseted bios but nothing again.

this is the pc with 2gb ram 667 / gt 210 / core 2 duo e6550 / 160 gb hdd.

What can i do ?

not much you can do... try a fresh install again.

Try it via a different medium this time? maybe your DVD drive is not working well? Perhaps the disc is scratched in just the wrong spot?

Check HDD for errors, and run memtestx86+ for a few hours.

Unplug all USB devices (except for keys and mice), they can cause issues occacionally during the initial install process. After windows is all set, then you can plug them back in.

Tried with 3 HDD till now. Even with ps2 mouse / keyboard and nothing.

When i tried last time to get into repair mode it gave me a BSOD.

I even removed the GPU and tried to boot with onboard still same problem.

BSOD typically means a hardware issue, most likely RAM related. try the Windows Memory Diagnostic, and memtestx86+ and see if that crops up any failures.

I changed 3 ram stick's one at a time but still no boot :S

Reset cmos but nothing.This board is strange

don't change the sticks, test them.

Once you identify errors on a stick then you can try the same stick in a different slot and determine if it is the stick that is bad, or the board itself, or some annoying combination of the two.

It could be the CPU overheating, or a faulty power supply.

@caedenv i mean i tried all the possibilities with RAM.

I dont think CPU overheats. In bios when it start up its 25 Degrees.

And i dont think its the psu ? Cuz if i let the comp lets say in bios or where i have to choose between startup repair and normal it stays on.

Just when i try to do smthing like choosing startup repair or booting DVD it fails. BSOD

I am currently having a very similar problem. I even ordered a new set of ram, but that did not solve the problem. I hope someone can solve your problem because it might be able to help me.

moving ram around is not the same as testing it. It could be the board, it could be a power supply issue, it could be a bad DVD rom, it could be a great number of things.

Most of the time however, with issues like you are describing, it is a RAM issue. Run memtestx86+ for ~1-2 hours per GB of ram installed, with only 1 stick physically installed at a time, and then come back with us with the results. If a ram stick fails, then try the test on the same stick in a different slot, and then in a different computer (if you have one available). The idea of troubbleshooting begins with valadating what hardware works, and if you simply move things around without any actual work being done then you may miss something that could save you from needing to purchase a whole new system.

if you believe the DVD rom to be the issue then you are in luck! they only cost $18 for a burner these days, so simply replace it. Even if you are wrong, and there is nothing wrong with your current drive I doubt you will lose much sleep over $20.

Also, if you believe the DVD drive to be the issue you can always try loading from a USB flash drive. MS has a free utility you can run which will take a USB flash drive, make it bootable, and then copy all of the install files to it:

So i tried with other RAM stick (working one) and the same result . It has 4x slot and still it fail.

As about the dvd it works cuz i use it in my current system.

I tried booting from USB and the same error.

Im starting to think the board is the problem

It could very well be the CPU overheating. If there is too much thermal paste then the CPU will get really really hot, while the cooler stays just moderately warm. If there is something physically wrong with the CPU (or voltage regulators on the mobo, or voltage coming from the PSU) then it can get hot as well, and the CPU cooler will be hot to the touch. 26*c sounds like a healthy believable number though.

If the Ram turns out to not be the issue, then the PSU would be the next likely culperate, followed by the mobo. Sadly, the only way to properly test a PSU is when it is under load... and that generally requires software to be installed and running while watching voltages on a utility. Any voltages outside ~5-10% means it is time for a new power supply, it does not need to be off by much to cause instability, though it does need to be off by quite a bit to cause damage these days.

Do you have a different board to try your current ram in to test it? If the mobo's ram voltage control has gone to pot then it can take out your Ram sticks (I had this problem with my first ex3 gen3 mobo... quite frustrating as the system worked fine for 2 months before the issue cropped up).

I would still suspect the power supply over the motherboard. Or rather, if your motherboard is having issues I would suspect that your power supply is also bad, and that replacing the mobo with a new one would just be a temp fix until the PSU blows that mobo out as well.

which HP 7800 is it? I work with them all the time, and have had pretty good luck with most of them. Perhaps check the motherboard for bad capacitors? Any pregnant or bleeding caps means that it is time to upgrade.

Its a 7800 convertible minitower.

Origginally comes with 80 Gb / 1Gb 667 / E 6550 Intel.

The mobo was working fine. It all started when i changed HDD.

Im gonna try a different PSU.

Still nothing even with a new psu. Cant do anything with that mobo. I cant even boot from somthing. It gives BSOD everytime.

try resetting bios (remove battery for a few minutes), then get into BIOS and load the optimized defaults. Be sure to reload any settings that are required for your setup manually. It may very well do nothing, but worth a try.

when going through the setup process are you cleaning the drive each time? (delete all partitions, make new partition, format). I have had a few frustrating experiences where the win setup does not remove all the old files on the drive, and then gets stuck trying to boot from an install for another machine (resulting in a BSOD)... but to be honest it has only happened once.. and I think it was back in win2K days

Ill give it a try today and ill come here again  

Just to say when i leave the comp in bios for 10-25 minutes it dsnt give me BSOD so it musn't be a hardware problem. Ill try it with a NEW HDD .
