PC is randomly crashing!

Soooo I've had my PC for about 2-3 years now and have never had a problem with it except my graphics card randomly died on me a year ago. Now recently (1 month at max) my PC as been crashing every couple of days and the only way to fix it is to hold down the power button and turn back on, after that it will be fine for the next 2/3 days or until it decides to do it again.

I honestly have no idea why this is happening, nothing has changed, nothing has happened to it within this time frame except being cleaned out. I don't even know what to tell you guys to get some help for this other than what I have already wrote and my pc specs.

Mobo taken from my old Packard Bell not sure what the details of it are, tried finding out not really much use except ixtreme M5800 American megatrends.

CPU: Intel i5 650 clarkdale @3.2ghz

RAM: Samsung 1 x 2 GB and 1 x 1 GB DDR3

GPU: ASUS GTX 550ti

PSU: Antec 25 550W VP550P

Does anyone have an idea why this is happening? Any help would be greatly appreciated.


Edit: Sometimes my pc freezes for a minute or 2 when I click on a link and it opens a new tab (I use google chrome), other than that it will just crash at random there is no specific time it will happen.

click on the download@majorgeeks link under download locations at the top. there should be 2 of them, click on the first one and it will open up a page and download the setup.

As far as memtest it'll run as long as you let it. More than a few hours is probably unnecessary and like I said sometimes errors wont occur during the test despite the RAM being faulty. It is a free program afterall so it is what it is.

Try the ram sticks 1 at a time ( yes i know that could be awkward with the 1 gig stick) as memtest is not great at finding faults. Borrow a psu off a pal. Esp. If the pc freezes up on startup you can bet its the psu.
Did the psu come from the pack bell as well?

How am I supposed to tell if it's the RAM? Just use 1 stick at a time and wait a few days? (I notice how that sounds but I'm genuinely asking)

No, sorry I'll edit the PSU into the original post. It's a Antec 25 550W VP550P

You can run memtest86, but it doesn't always show errors although the sticks may still be bad. It does sound like a memory issue though.

More memory would help alot too regardless and mixing and matching ram isnt generally a good idea so I've heard. Might be wrong, but you would be best off getting a dual channel kit like 2-4gb sticks.

I've just put my PC on a few minutes ago and realise that the GPU meter is saying that the clock speed is 0 no matter what I do (It was fine last night). I tried 3DMARK, the 1st 2 tests ran fine until the second tests physics test it hit 9FPS (probably due to having an on-board graphics aswell) but the 3rd test was just unbearable. So I'm certain that my GPU has gone but I will try doing the memtest as well because I doubt my gpu was causing the crashes but I don't know. What exactly am I looking for on the memtest?

memtest has a column that shows the number of error occurrences so there's nothing you really have to do besides let it run. It does take quite a while so run it overnight or something. Strange with your GPU showing no clock speed though. Make sure your drivers are up to date and that it is seated correctly in the PCI slot. Try another stress program like furmark and see if it shows the same issue.

memtest has been going for over an hour now and has completed 2 tests without errors, does it automatically stop or do I have to press esc like the prompt says? I've already checked the drivers so I know it's not that, I'll check to see if it's in place correctly and try the Furmark after the memtest is done. Can you link me to the Furmark please? I was looking at it earlier but I couldn't find the download only a bunch of fake download ads.

This is what I got from Furmark http://
It hit 91 degrees on the first test, The highest I've seen is 70 before this.

Well your getting pretty good fps considering you had AA set to 4. And 91 is pretty high, the max is 100 for that card though. Have you cleaned any dust that could be built up inside the card?

And are you able to borrow ram from anyone to test in your computer?

I cleaned out my PC pretty recently but I will take a look again in a minute, as for borrowing ram the only person I know that has a semi decent PC doesn't live too close to me so I don't think I can really do that.

Edit: The graphics card is fine now, I just changed a few things in the application and it seems to be showing the clock speed now. Just waiting to see when it crashes again which is a pain in the ass because it's not a timed event it's completely random :/
