Computer Randomly Restarts

I seem to be having a similar problem as other members on this site - random restarts. I get no blue screen, no notification, no nothing. The screen goes black, and next thing I know its running diagnostics and rebooting.

Since a number of other threads have requested Everest reports of temp and voltage, here you go:

Temperatures:
Motherboard 35 °C (95 °F)
CPU 46 °C (115 °F)
GPU 60 °C (140 °F)
Seagate ST380011A 38 °C (100 °F)

Cooling Fans:
CPU 2836 RPM

Voltage Values:
CPU Core 1.41 V
Aux 3.06 V
+3.3 V 3.34 V
+5 V 4.97 V
+12 V 2.05 V
+5 V Standby 4.98 V
VBAT Battery 3.20 V
Debug Info F FF EE FF
Debug Info T 35 46 208
Debug Info V 93 BF D1 B9 20 60 51 (01)


If there's anything else I can do, don't hesitate to ask. I'll tell you the computer stays on generally anywhere from 10 minutes to hours at a time. Today was the worst ever, though - it restarted once, and then could not get past the diagnostics (5-10 seconds) before restarting. Did this 4-5 times before I just shut it down and walked away. The cover is open, the fans are running.

Any suggestions/comments/support is appreciated.

Thanks

 

Is your windows update service enabled??? Sometimes when your computer restarts due to new Windows Updates stuff.

 

General approach starts with a good cleaning to improve cooling.
Turn computer off and pull power cord. It never hurts to push start-up button a couple of time to discharge power supply.
Works best if you pull the computer out and remove the side panels.
Have available a can of compressed air, a small soft bristle brush. Any non-conductive object which can pick and poke into small areas is always helpful. Some use a vacuum cleaner at times, but legend says a static charge may develop. When using compressed air be careful not to direct flow into any fans, as this may over-rev and caused motor damage.
Once completed, reseat any cards, ram memory, power connections.
Bring system back up and with luck you may have solved the problem.
Hardware failing - Process of elimination.
Generally the most common is a weak power supply unit. If you have another available to you, swap it out.
Back in the Windows 3.1 days I experienced the same problem (system reboots). Replaced the ram memory, problem fixed. IF you are running TWO or more memory modules, remove all and install ONE (in proper slot) and power up for test. If problem goes away, the non-installed memory module(s) are weak. If not, continue to swap out ONE at a time.
In most causes, one of the above will isolate the problem.
Keep us posted.

 

Hello, jk,

I notice your +12V voltage under "Voltage Values" is very low @ 2.05V. I am not an expert on what this means but may indicate a failing power supply which could cause your computer to randomly restart from lack of power. Value should be much closer to 12V. Wait until a hardware expert comments and see if he/she can suggest a remedy. I would also suggest in the meantime you expand on your system specs. as just stating you have a 32 bit OS doesn't mean too much.

 

Updated as much of my system details as I could. Didn't know the PSU info, though. If it's needed, I'll open up the computer and get it.

Also checked the power info using SIW:

Your voltages look good in the SIW report. So unless it is an intermittant problem with the PSU I would look for the cause elsewhere. Try the steps that Dennis L outlined in his post.

 

[FONT= "Comic Sans MS"]Easy way to solve, take this from my job since 1995
look everything to fix pc depend by try change something in u r case So,
try this for u r problem.
I see ,
before doing this try scan u r system from virus or Trojan -----> 70%
1.try replace Ps. 30%
2.change a new Ram for test. 60%
3.check u r hardisk for bad sector. 20%
4.change cable both for hardisk and DVD or CD,rom. 10%
5.replace display card or remove it and work in built in card. 50%
6.cpu crash inside . 10%
7.update u r bios " be careful ". 5%
8.some trouble in u r motherboard exact in Southbridge. 20%
----------
I think I late for reply ,but tell me wt happen with u if u r fix some thing.
be in touch
