Computer randomly freezes, needs force reboot.

[Phen8210]

Hi, it happens randomly especially on first boot of the day.
how can i troubleshoot this?

ram no errors.
hdd no errors

 

[zetken]

ram first? haha take out and use eraser rub on the gold connector. put back in. see whether works. if not

u have to plug in and out for various component. gpu, hdd all this.

but it don't happen often so using plug in plug out method won't work =(.

i erased with eraser already haha, but still happened again today.

bump need more help!

this morning at the loading windows 7 logo it freeze again, is it because it has usb device attach?

Since you reformatted before, unlikely to be a software issue, most prob a hardware problem.

For random reboot, likely to be PSU problem actually.

1. If you can go to BIOS, check system temperature for anomalies.

2. Remove all USB device to make sure it is not bad device interfering with booting up (bad sector HDD etc).

3. Open up your PC to clean out all dust, check that no obstruction to case/PC/PSU fan; this may cause overheating which will cause shut down (happened to me once, random shutdown kept happening, once I clean out the dust, CPU running like new again).

4. Visually check all your component for signs of defects (got once my bro's PSU literally melted, but he still managed to use it for weeks with only occasional restarts).

5. If all else fails, unplug component one by one as mentioned by others, see if you can isolate the problem, then replace damaged parts.

If you can go to BIOS, check system temperature for anomalies.

Start with 1 ram at a time first, because it is the easiest. Followed by the GPU.

Testing the PSU is a bit tricky, can take from old comp or borrow from friend. (or buy a backup)

Unlikely to be bad HDD though, if not you can't even boot up to OS or safe mode properly. But if you suspect HDD got problem, can run a crystaldiskinfo test when you finish reinstalling OS or using another comp. (or buy a backup)

Edit: Actually, it could be a HDD issue. HDD problems may start small (random reboots, freezing etc) until it blows up (cannot boot or install OS).

Since you "only" have a 500GB HDD, you might want to consider upgrading to a SSD + 2TB Seagate combo. Totally worth it.

If all the above fail, the problem is likely the Motherboard or CPU.

1. Use memtest86 to check your memory
2. Use HDTune to scan your hard disk for bad sectors. Do not check quick scan.

 

[wtfwfs]

it happened to me before.... 1st mth after building my pc...
while using my comp and any point it will just hang with the sound like zzzzzzzzzzzz coming from my speakers... ran memtest and alll couldnt rectify but i believe is my ram causing it...

so YOLO i went all the way out to RMA my ram... both of it.. and yeap... done

no more jam or hang

maybe u also wan try regcure pro...

1. Checked, system temperature fine and not the cause because it hanged during low temp.

2. Unsure, only sometimes it happens and i'm not sure if that's the cause.

3. Did few months ago, just 2 days ago i removed the graphic card and ram to clean the gold contacts with eraser.

4. No sign of defects.

5. That's impossible because because I've nothing to replace the parts and I'm still not sure if it's a hardware or software issue as the drivers these day are generally unstable (especially nvidia drivers) and since it happens really seldom but randomly, troubleshooting like that could take many months.

I did a test with HDtune, it shows my hdd is 100% free of errors.
Performing memtest now, gonna burn onto dvd..

 

[wad3v3r]

memtest have to do overnight unless ur rams really screwed up..

if still no errors might be cpu issues/mobo issues .. cpu dying...

mobo pin bent etc


anyways recently i had the same issue as u..
just that mine happens when i played games.. even games that arent demanding like dota2

my screen goes splitscreenish and becomes solid colors and freezes.. cant use reboot button.. had to force reboot using power button..

tried with 2gfx card both same issue.. tried single ram both pieces also freeze.... monitored temperature was fine.. use multimeter to test psu voltage under just load of 3 fans.. voltage seems fine...

just sent in my mobo and apparently theres bent pins.. but donno if its me who bent the pin when removing the chip or what.. now waiting for mobo to be back to continue..

 

[GhostWhere29]

for my case is psu got problem, thats why keep freeze and force reboot

 

[zetken]

yep. i have seen with psu too. weird but true.

 

[Phen8210]

How to know if its the psu? My memtest is still running no errors so far

 

[jtjt00]

Run HDTune to scan your hard disk?

[Phen8210]

both hdd and ram have no issues.
no errors from memtest86 and HDtune.

hope it isn't a motherboard or graphic card issue.. it will be really troublesome..

for the easier part.. use ur onboard motherboard voltage monitors to take a look at the voltages lor...

12v
3.3v
5v

all 3 must be within 5% +- .. if too low means psu dying but might be that ur psu spike when on high load.. so must see one

 

[jtjt00]

Remove the 560 graphics card and use onboard IGP if freeze still occur?

3.3v
5v

just checked.
12v - 11.93 (significant difference from both)
3.3v - 3.3x (normal)
5v- 5.0x (normal)

i would say the load is average when it hangs.. something like loading web browser etc.

+12V 12.096V
+VCC 3.400V
vAXG 2.220V

mean my psu got problem???

Need to monitor the +5v supply, maybe use hardware monitor (software name) and capture the screen shot and show here will be better
