Solved Computer randomly crashes!

May 23, 2011 at 12:49:50
Specs: Windows 7, Intel E6750, 4gb ram
hello. i'll cut straight to the chase with my strangle problem, here we go.

Intel E6750 dualcore processor
ATI Radeon HD5670
4gb RAM
ocz 600w PSU
windows 7

now I would love to give you more information about them, but heres the problem. When I turn the pc on, I can get to windows properly and so on, but whenever I do something (anything tbh, open programs, start menu and stuff) the computer just closes, then restarts but the front panel (i have a NZXT Hush case) LEDs and power light is flashing (not normal flashing with same time interval between each flash, but like broken flashing hard to explain) and the fans inside sound like theyre running half power, and nothing appears on the screen. I have to press the power button next to the PSU like 3-4 times in order to normally boot my computer again... then this crash problem happens again

anyone has had similar experiences or might know what causes this? i would love to give more information on the parts and stuff but I can't even get up to dxdiag or any other program that shows information about components before it crashes.

sorry if this is badly written,i am somewhat tired of fighting with this problem for the whole day after a long day in work

i ran CHKDSK over the night (the pc doesnt crash in safe mode at all), and did memtests, everything was OK in the tests and chkdsk finished normally.

also what i noticed is, when the pc crashes and reboots, all the fans start working but i cant hear anything from the hard-drive (AFTER the crash), could this be a hard-drive OR even a software (driver) issue?

to answer the questions few posts above: i bought this PC a bit over year ago, i upgraded from vista to 7 with the total upgrade thing not saving anything. it was not a "packet computer" (well in a sense it was, since i didnt build it, the company did). i have changed the graphics card once myself (card was replaced yesterday, i was told graphics card was causing this at first but obviously not, well atleast now I have x2 the same cards that I can run together when I get this thing working).

drivers have also all been updated to windows 7.

Two things (or more) cause a crash. One is OS and the other is hardware.

As to which to trouble shoot first is your choice.

I think I'd boot to safe mode maybe and see if I could access event logs or even see if anything works in safe mode.

Otherwise hardware may be to start in bios and see if your memory is reported correctly and see any temps if shown. Then move on to memory diagnostics and maybe look at power supply.

I checked the event logs (im assuming you mean the crash logs in control panel?) in safe mode and there is nothing in there. also safe mode doesnt seem to crash that easily (didn't get a crash in 15 minutes)

i checked bios for the temps, they show up (processor was at like ~30c) and i will check the memory out in a minute.

how do i do memory dignostics and/or take a "look" (assuming you mean testing" my PSU?

thank you for responding hope you can help me even more

Windows can check memory. (now in Vista and W7)

http://oca.microsoft.com/en/windiag...

http://windows.microsoft.com/en-US/...


There are hundreds of a different OS out there. Get almost any linux live cd and run memtest. Special CD's like ultimate boot cd have easy to follow menu. You download a cd image and use a program that can burn images to cd's.

As far a power supply it is most easily tested with a known good one swapped in. There are so so web pages devoted to some tests.

Power supply seems to be common. Ram errors seem to be common. Almost any hardware can cause a crash.


I mean event logs not crash logs. Use event log viewer to see issues. It may be too many but wade through it maybe. See help and support for event viewer.

Try resetting BIOS to defaults.
Run Memtest to test memory (A quick test would be remove one memory stick at a time and start the system, repeat with the second one. Not as much details, but may confirm quickly a memory stick problem.).

More details like: Make/Model? Is this a custom rig? Did you build or purchase? Is it new? Has it run properly up until now? Any other recent problems? Was this an upgrade to Windows 7? From what? How recently? Were Windows 7 drivers installed?
With these answers there will likely be more questions trying to narrow down the possibilities.

run a disk check and check for damaged sectors both check boxes should be checked in disk check..
it will take a few hours, but may solve your problem.

Since it is working perfectly in safe mode and disk and memory tests Ok, you have one more piece of hardware you probably should test and that it your power supply (After that, I would look to software issue). Even though it works in safe mode, in safe mode you may not be running your graphics card under as much stress so either your power supply is marginal as far as power on it's 12volt rails(s) or it is on it's way out. Unfortunately, the best test would be to swap it out with another one you know is working (or new) and preferably with a single 12V rail. If you have not, try getting the latest graphics driver to eliminate that possibility also. Also if the LED flashing is following a pattern then it may be a diagnostic signal to you like beep codes on some motherboards, if so, then Google information on your motherboard (since you did not list the make/model) for the online manual and/or an LED flash code chart. That could point you directly towards a specific hardware issue.
If you can eliminate the above, then you need to seriously consider software. If this began recently, try a system restore to before the problem started giving you trouble. If it has been trouble since shortly after install, consider backing up and reinstalling.

download system information for windows, siw, it will tell you a lot about your system, running temps, power, running process's what your system is made up of,tells you loads of usefull stuff in one window and may help you find the issue.
as it works in safe mode, i would consider a full run of anti virus, malwarebytes, reinstall the graphics driver but delete it from the device manager and check remove all drivers button, then reboot, finally a full system reinstall, if all this fails including trying a different power supply, let us know.

I did a full clear of my windows, and started reinstalling it (to a totally new windows from the official DVD)... and it crashed mid-way install. I'm guessing software issue is out of the way?

I will try to get ahold of another power supply and test it out. (I have no clue where to pick one... I heard theyre somewhat expensive?)

Also test your memory with Memtest since and disk check as mentioned above since both of these can also cause these problems and failed OS install. Memtest works outside of OS so it does not need you to reinstall first and you can also download disk utilities from the manufacturer of your hard drive to test your hard drive for problems and this will also operate outside of windows, you just burn them to CD and boot to them. I would do this first since this will only cost you 2 blank CDr's before you spend for a power supply.
