PC problem determination

OK I will try to describe in detail what happened.Two weeks ago while I was playing WoW smoothly for two hours it suddenly froze. First the screen froze but the sound was fine. After 4-5 secs the sound got messed up too and then after 4-5 secs again everything got fine. Then the problem became worse. Those freezings started to repeat more often 'till the time between the was 1 sec and even worse in the end it froze completely. I thought it may be some kind of an addon which caused the problem and so I opened WoW to try disabling them but it froze completely in the login screen. From now on, every time I opened WoW it froze in the login screen. I searched in the internet and I found that many had almost the same problems with no sertain solution. But it doesn't stop there. After a couple of hours my comp started acting strange (while I wasn't in the game). The screen went from normal to black many times before my whole computer froze. I reseted it and in the Windows welcome backround it started doing the same thing. I noticed that the Windows welcome backround was a little bit distorted and then it froze (again). After the restart the screen was black and for a while it gave me the message ''Power Saving Mode'' and the monitor's light went from green to orange. I saw that the keyboard worked and I could enter in my account blind. I thought it may be the PSU or the graphic card that had the problem so I changed them both with the same I had before. After that everything was fine... for four days when while I was playing WoW (again) it froze and I could see the same kind of destorted screen as before. I reseted my pc and I could see that the letters of the BIOS where diformed, like they are missing some pixels. The loading took me longer than the usual and once done the black screen came up with the ''Power Saving Mode'' message. Now I can only use my computer in safe mode.I am running my computer on Windows XP (Home Edition), sp2 with Intel Core 2 Duo 6600 @ 2.40GHz, 2GB RAM and NVIDIA GeForce 7600 GS Any help would be appriciated.PC problem determination

So you say you've tried a new PSU and graphics card but the same problem came back a few days later... What psu and graphics did you used to have? What psu are you using now? What motherboard do you have?
It is most likely graphic card problem. Other problems are coused by corrupted or damaged files caused by reseting. If graphic isn't a problem then it is the motherboard. Hardware is only thing that can cause errors in bios.

I don't remember the PSU and I don't want to open my computer to see it (I want to stay as far away from opening my computer as possible because I don't know much about those things). The problem I had before is not exactly the same as before. The previous time it said me the message from the computer start up and I could get in my account blind. Now the message appears after the windows load and I can't get in my account as before.And my motherboard is Gigabyte GA-945P-S3 v1.

If there are some kind of corrupted files how can I detect them and delete them? Is there a possibility that the PSU can't provide the graphic card enough power?
You can repair your windows with your windows CD. Just boot from your windows cd and you should see that option. -Is there a possibility that the PSU can't provide the graphic card enough power? Yes. But it could be your motherboard also.

[/QUOTE]I want to be sure that the problem is in any of my computer's parts before changing it so I want to exclude any other possibilities. So, how can I make sure the psu is sending enough power to my graphic card? And why did it worked fine for some days before starting doing it again?

Well you can test your PSU. How? You need to have voltmeter. Take out the PSU . Connect pin 11 to pin 12 with some conductor on the connector that goes in your motherboard (this will make PSU work without being connected to motherboard); plug in your PSU in the power and start measuring!If you think that would be too much maybe it is time to consider taking your PC to service.
Thank you very much. I will try doing it and if I can't I will just send it for service.
Np. And to answer your question -why did it worked fine for some days before starting doing it again You may have a broken conductor in your PSU; so due to vibrations of your PC it could be that it connected/disconnected.If you understand electronic you could actuly try to find that part where it (if it is) broken, and put it back together. But that is not recommended.Remember to be carefull. Good luck!
The thing is that I changed my PSU and then it happened again. Do you mean that this PSU and the one I had before have the a broken conductor? How many chances are there that both of them are problematic?
It was impossible for me to mean that because you did not stated that you tryed another PSU. Well chances are low; so i suggest that you look for problem in motherboard.
I did said that I tryed another PSU, just look at demonx5584's post. But it's ok don't mind :). I do hope that it is the motherboard because I don't want to think it may be something like a program which is causing the problem (correct me if I am saying crap).
Well i told you it may be graphic or motherboard just after that... It could be alos that the other PSU doesnt have enought power. Anyway it cannot be program.
OK, let's make a list of the problem possibilities my computer has:-Faulty drivers-PSU can't provide graphic card with enough power-Corrupted files-Motherboard I don't think it is my graphic card because I canged it. Can you please help me complete the list? The first time the problem occurred and I sent it for service I told them that it may be a PSU or a graphic card problem and the only thing they did is replace them and they didn't find out what my computer has at all.
I think about something else. Could it be RAM? I think it is RAM that is causing all the trouble. Is there a way to find out if it is RAM after all?
sounds more like a corrupted ram or a nasty virus, Unless it was a hdd problem, but you haven't mentioned any problem with the hdd, you should check your HDD just to see if it makes weird sounds
