Lots of blue screens and problems booting up - help please

Yesterday my PC randomly rebooted, then I started getting some BSOD's either during bootup (usually at login screen) or on desktop. I thought it was the graphics driver because I had been getting a few "display driver stopped responding" errors before this.

So I tried to uninstall the driver and it came up with an error, such as can't access the DLL or something. I ran driver cleaner then rebooted a few times and it uninstalled after a while. The version I had here was: 266.58 (nvidia)

Then I reinstalled the same driver, but I had the same problems, so I uninstalled it (no problems this time) and installed a previous version (260.99).

After that everything worked fine for a while last night so I thought that had fixed it. But after using the PC again this morning it had a BSOD on desktop, then another when booting up, and 3-4 more on log in screen. I finally managed to boot into safe mode, but it wasn't working correctly, I couldn't even open My Computer. It kept saying Windows Explorer stopped responding.

Then I rebooted back into normal mode and it worked, but applications were not opening correctly and Firefox took 3 mins to open. Also my Avast antivirus says Unsecured, and when I press fix now it seemingly does nothing.

So what do you think? Could be a virus? Damaged windows file?

Any help is much appriciated!

e : specs are:

i5 760
GTX 470
ASUS P7P55D-E
Corsair XMS3 4GB DDR3
Windows 7 64 bit

Nothing is overclocked.

No one has any ideas? I'm really stuck as to what to do here.

Small update:

I've managed to enable Avast again, and I've run Avast, Malwarebytes and Spybot S&D. None of them came up with any problems.

I've also updated to the latest Nvidia drivers (275.33). But even with no graphics driver installed there was a BSOD.

I also forgot to mention I've tried re-seating the graphics card.

Maybe this thread would be better suited to the Windows & Other Software forum.
 
Run memtest for a while, see what you get.

Check your HDD for errors with HDTune.

Report back with your results ;)

ok I'm running HDTune Error Scan now. I'll do memtest after.

What psu are you using?

It's an OCZ 700w one, I don't remember the name, it is years old too. edit: found it, it's OCZ GameXStream 700w.

Did you manage to catch what error you're getting from the BSOD? it might be worth Googling the error.

No but I know one of them said "Service" something. I have got some minidump .dmp files from the BSOD's if anyone could look at them for me? Personally I don't even know how to open them.

ok, I did HDTune, 0 errors.

I did memtest with both sticks in, 14000 errors...

took one stick out and it got errors imedately so i stopped it. Now, I'm testing the other stick alone, so far 0 errors. How long should I test this stick for? not really used memtest before.

Run it for a couple of hours. But it seems as if you have definitely got a dead stick. Do you still get the BSoD's when you do not use the faulty module?

Yeah it seems that way. I'll run it for a while more, it's about to finish 2nd pass. I haven't had chance to test if I still get BSOD without the stick that gave errors, i'll do that after these tests. There's still a chance it could be the mb memory module. I'll test that too after.

I've not had much luck with my pc recently I had to RMA the motherboard for faulty memory module, then sound card had problems RMAd that too. And now either RAM is dying or motherboard memory module faulty again (I would laugh) these items were all from same order too, hmmm....

Thanks for your suggestion on memtest by the way.
 
ok, can you explain this?

Stick 1:

- Left slot: Memtest errors but boots
- Right slot: Memtest errors but boots

Stick 2:

- Left slot: No memtest errors and boots normally
- Right slot: Can't run memtest (when I select memtest USB boot device it hangs on cmd prompt and doesnt run, then goes into booting) and it doesnt boot normally (very slow)

Very odd. It seems with stick 2 in right slot usb doesnt work correctly on bootup.

Does it look like 1 stick of RAM is faulty and also 1 memory module on the motherboard is faulty? :confused:

only way to be sure is get another ram stick (one you mentioned is definetly dud), it does sound possible that the right slot could be dodgy also but i would check first it doesnt have any dust or similair first.

ive also had all sorts of fun with RAM for the past few days, 4 sticks, 1 dodgy one, intermittent issues with RAID controller and all sorts :)
 
I'm testing the PC without the faulty RAM stick to see if I have any problems today to make sure that was the problem. So far so good. (apart from the slowness with only 2gb RAM :/)
