Hi all, recently been having an issue with my PC. About a month or two ago, whilst gaming, my PC suddenly lost power, as though someone had pulled the plug. My speakers (powered through the PC), various USB lights and keyboard lights were still on though. I simply turned the PC back on without any trouble, brushing it off as bad wiring connection or something. However, this has been re-ocurring at least once per night ever since.
Anyway, I recently upgraded my Graphics card from NVIDIA 9500 GT to a 450 GTS. After I took out my old card and put my old one in, I tried booting up the PC but it only got the log-in screen before it died. I tried again and the same thing happened, only a little bit sooner. So obviously I was a bit worried about the new card, tried swapping my old one back in, but the same sort of thing is now happening, rendering the PC pretty much useless. Since this I have tried powering up my PC without any graphics card installed, and also took out my TV tuner, and just seeing how long it will last, and the answer is about the same as WITH either of the graphics cards installed!
I've had a few suggestions as to the problem. Someone has suggested that the PSU is not powerful enough, which is what I originally thought. It is a 400W but about 5 or 6 years old, and the minimum for the new 450 GTS card is 400/450 W. However, if this is the case then surely it would work fine with no graphics card installed, or even my old one? Someone else suggested that the PSU is simply faulty, and was made worse by trying the new graphics card as it fried it (or something like that). I have given the PC a thorough clean but this makes no difference. Obviously PSU is a likely candidate for the problem, but are there any other ideas as to what it may be? To finish, please note that I don't really have access to many spare components. Also, here are my specs:
Medion PC (unsure of model)
AMD Phenom X Quad-core 2.2 GHz.
4GB DDR3 RAM.
400W Power Supply.
NVIDIA 9500 GT / 450 GTS Graphics cards.
1x500GB HDD.
I am happy to supply any other Information you may require. PLEASE HELP! Thankyou in advance for any suggestions!
