some help about a computer im trying to fix

[ChknFngr]

So i got to fix this +- 8 years old computer

 

From what i've been told, the problem is it crashed a few times while running videos + game at same times,

i thought maybe its just the heat, a bit of dust off and we'll be good to go.

 

so i opened it and cleaned fans and video card.

put back everything and start it again.

 

windows 7 start and get to the desktop, it still launching everything and boom, it crash.

everytime.

 

start it in safe mode and it runs fine.

virus check, it had some trojans, i cleaned them all.

 

but the damn thing still crash.

 

one thing is that it had like an electrical short a few months ago.

 

So i think it may be the cause of the problem, the PSU is maybe degraded, even if it is a really good one.

So before buying a new PSU, can one of u idiot expert confirm it is the problem ? something else i can try/test/check ?

 

oh yea i also removed all RAM sticks, put only one, same thing.

 

so PSU, Video card or something else ?

Remove all memory and add one at a time. Sound like hardware related because you get no blue screen correct?

 

If in save mode and it works it is because you have not hit the bad spot in the memory yet. 

 

Next I would look at the CPU if it is overheating. Put a house fan on it to test it out. 

 

As for the PSU.. to a voltage check. If you get 12v and 5v then it is not the problem. If it was a current problem then it would be a diod or cap problem and it would not give the correct voltage. I have had my 5v let die on a Power Supply before. Imagine what a pain it was to troubleshoot that. So now I check if having a problem.

 

Does not sound like OS but I would also not ruled it out. 

 

Good luck hope some of this helps.

Oh and it could be a driver problem. Most likely not unless you were upgrading drivers.

i get bsod

 

but it seems sometimes it just crash

i tested with each memory stick, and it always crash/bsod

 

but im gona test this again

 

this shit is giving me headache now, gona take a lil break before testing again

blue screen most of the time will be driver or just an os problem. Throw a new os on it and see what happens. If you have a spare drive it will help just in case that is not is. But does not sound like hardware.

Check you PM.. I sent you a link to a tool.

When windows 7 first came out it was famous for blue screen of death. Make sure windows is all updated and then run the windows fix program. Should cure the issue. Run cCleaner also with a registry fix/clean and it should fix or remove any bad sectors. Then defrag.

[MtDeW]

cpuz hardware monitor will tell you your voltages and temps!

[ChknFngr]

thank you all, i will test all those

if it doesnt work, i have a spare SSD that i could install a new windows on it

what u mean by run windows fix program ?

 

also it seems windows update isnt available in safe mode, so i cant update

 

i had to run a registry check 3 times to fix all registry errors.

but that did not fix the problem :/

i can't recall the path but somewhere in control panel under I think maintenance there is an option to have windows scan for and fix errors or at minimum identify any issues

[little_old_man]

If it's crashing in regular mode but running fine in safe mode, more than likely it is a software problem. The only exception would be if the graphics card is bad and it's under more of a load when running in regular mode. Even though the installer won't work while in safe mode you can still check to see which updates it needs then install them manually without the auto installer. Just make sure you start in safe mode "with networking" to have access to the internet, then check to see which updates it needs and write them down. This would also be a good time to run your anti-virus and malware program. You should also do a scandisk while in safe mode to see if you have any bad sectors on the hard drive.

 

If all else fails see how far back the system restore goes. You might get lucky and have a file saved from when the PC was fairly new, and you can reload everything from that point which will hopefully get rid of the problem. If you have the original windows 7 CD, you can also reinstall the OS, but you'll lose any personal files on the PC.

 

Good luck.

[ChknFngr]

ok thank you all for all advices and infos.

 

i checked almost all i could, nothing worked as expected.

i could go further with more tools, but honestly im tired and its too much of a hassle

 

so i install a fresh new windows on the spare SSD, and everything works now.

so u were right, wasnt the PSU, nor the graphic card, no the ram.

 

 

anyway gona back up all i can now, and then format the faulty drive

not sure if i will keep it as it could have been damaged by the short circuit.

 

btw even on an old system like this one, a SSD makes everything smooth and fast.

its not a beast but damn i love those SSDs

 

anyway thank you all

but im gona test this again

could be harddrive error as well....try different harddrive see if it still crashes....if it does my guess is memory bank slots are bad which means mobo is probably bad...which mobo being bad is still a possibility reguardless too...

[CobraBites]

after i posted above i then read ur post above mine...lol ...guess it was harddrive that was bad lol..nj

 

i would say that 9 times out of 10 that bsod usually a bad harddrive issue....1 out 10 is bad memory issue

[ChknFngr]

well i spoke too soon,

 

so yesterday everything was going good with the new hard drive, this morning i want to complete the installation of softwares and all, boom it crash at startup again even with the new drive and unlike yesterday ...

[ChknFngr]

so, now if i shut it down then boot it, i get a back screen.

i have to shut down the PSU, remove the cable, then plug it back, and it boot correctly.

so fkn weird.

 

so before it dies on me, i back everything on my nas.

 

but then im not sure what to do

[Hemps]

my bro PC started to crash when he was starting up war thunder, right when you get into the garage it would crash cause the video card would kick in, changed the power supply and all was good. he never had a problem before, seem the psu got weak!

[ChknFngr]

yea that was my first impression, the PSU got weak.

 

but now im not sure of anything anymore

 

i reinstalled the OS once again and everything was good untill it freeze completely while i was trying to download the antivirus.

 

so im gona go buy a new PSU and see, what else can i do ? i dunno

it may be the mobo, no ?

but then it would start to cost a lot, as i want to put a decent PSU, if i have to buy new mobo, CPU, hard drive and whatnot, ...

i am having the bsod random problem  runs longer in safe mode.  my problem is my mb finally ate a bullet after 8 months of holding the gun to its head and threatening to shoot itself.

ok latest news

 

i bought a new PSU, and it seems to have fix all the problems

except i think one circuit of the fan pwr got burned on the mobo, but i dont use it, so not really a problem.

so will have to replace that mobo one day, but yea we'll see in a few months or so.

 

the new PSU is a BE QUIET pure power up to 88% efficiency, and its super quiet, love that brand, i bought some fans for another computer and was very pleased with those, easy to clean, silent and really effective.
