Windows 7 crashing, blue screens, reboot problems

alexg42

Hi all

Recently, I've been having problems with my computer constantly rebooting itself, blue screens and just freezing. It happens no matter what I'm doing, even when left idle I would come back and I would find its frozen or rebooted. This PC is mainly used for gaming, as well as University work, but it seems to freeze when nothing is running or just the internet.


The freezing mainly happens on start up and within the first 10-20minutes of the computer being on, after that it's usually fine. I've had problems with it freezing on the motherboard splash screen, and while windows is loading at start up. Sometimes the computer would freeze on startup with a completely blank screen, and all lights on (disc tray etc).


I've tried a few things, like reinstalling sound and video drivers and cleaning the registry using software recommended to me but nothing has fixed it. I only did a clean install of windows 7 a month ago, as the problems were before that but not as bad as this.

Here are my computer specs:


Windows 7 32-bit Home Premium
AMD Athlon 64 X2 4800 CPU 2.50 GHz
ASUS M2V motherboard
250GB HDD
3GB DD2 RAM
GeForce 9800GT GPU

Any advice or help would be great and really appreciated, also if anymore information is needed please ask.


Thanks
Alex

Faulty hard drive ? As everything goes via the drive could well be the problem, as could faulty ram. Is the ram matched units ? When you say 3GB DDR ram do you mean 4GB, 2x 2GB ? If not take out the extra 1GB.

Do you have antivrus and anti malware protection thats up to date?

Does your harddrive click loudly?

Have you made any modifications to the PC?

You don't say whether its a lap or desktop, in either case blow out the airways in case its overheating.

alexg42

it's a desktop PC, yup I've run a full virus/spyware scan and found nothing.

The RAM is 2x 512mb and I added on 2x 1GB.

It's been fine today so far, not sure why but no problems yet

As it occasionally freezes on the BIOS screen, that pins it down to hardware failure rather than software.

First thing I'd check is that the CPU fan is clear of dust & crap, and that the CPU isn't getting overly hot.

and try removing the extra sticks of ram you put in .....

alexg42

don't think the extra sticks of RAM make a difference as it's run fine with them for almost a year, have checked and cleaned the fans

Could the problem be the motherboard?

Check your RAM with Win 7 memory diagnostic - http://www.tomstricks.com/how-to-test-your-ram-or-memory-with-windows-memory-diagnostic-tool-in-windows-7/

Check your CPU temp with - http://www.alcpu.com/CoreTemp/

Check your voltages with - http://www.cpuid.com/softwares/cpu-z.html

thanks TOG

core temp seems quite high 85-86 and 86-91 and voltages seem normal (1.296 ?) so it looks like thats the issue

I'm about to run the memory diagnostic as well

From AMD specs normal temp range for your cpu is 55 - 68 deg C.

Give the inside of case a thorough clean with a can of compressed air, paying particular attention to the cpu fan and heatsink vanes. See if that improves things.

What's the voltage reading on your 12V?
