Other computer randomly reboots

hellhunter · 05-08-2007, 09:25 AM

hi TSF, at the pc where my parents and sister are on keep rebooting randomly (not always)

Most Common Reboot things:
A: if u have to push your password if windows XP starts, it mostly gets stuck at the 3rd thing. Then u here a BEEEEP* the screen gets black. and reboots after like 1 min.

B: if u startup a program (its often at anti spyware programs)

the computer got formatted and the problem is still here.

i also did an other Power supply unit in it (we had 1) and that didnt worked.
also putted a video card out. but the problems still were there

what could be the problem???

RAM?

what? :P can some1 help me plz.

Thx hell

Well to start if you can give us the spec of the problem PC we may be able to see more, especially the PSU it's currently using (make\model), and the one you tested with.
There could be several reasons that can cause this, from faulty hardware to an infection, so we need to narrow it down and rule things out to get down to the probable cause.

Now you say it was formatted due to infection, was it a full format ? did you pull the CMOS battery and power to reset it ?
Also take note of the system temp's, some bios's have a hardware monitor in them that can give you this, or else Everest in my Sig or speedfan can tell you as well, reply with the above info and temp's and we can go from there.

i formatted with a help of a friend im not a big star in formatting :p.

but my Dad got a warning today.

A Blue screen (STOP warning thing)

theres something wrong with the NV4_disp.dll (videocard). my did did wrote down the warning:

Translated because he wrote it in dutch :P :
The problem is caused by the following file:
NV4_disp.dll

Bla bla bla (restarting thing and stuff)

xxx Stop: oxooooooEA(ok86403DA8, ox86573308,)xf7c62cB4 0x00000001

NV4_disp is busy with the start of a physical memory dump.

he wrote down this :p
installed newest drivers and stuff. didnt worked.

either the drivers are not installed correctley or there is not enough power for the card to run properly
in the device manager uninstall the card
reboot tapping f8 and choose vga mode
when windows finishes rebooting and reinstalling the card
disable a/virus
install your drivers
reboot the computer
