I use my desktop PC mostly for watching TV, downloading stuff and sometimes playing big games. Recently, I've been having some weird problems which I am unable to attribute to a particular component. Sometimes, irrespective of what I am doing, the monitor just switches off/goes blank and the system becomes dead!
I can see the power light glowing in the chassis, but none of the components seem to work, even the restart button. I thought the problem might be a loose contact between some components inside the chassis, so I opened the box, removed dust, re-fitted the TV tuner and graphics card. Still the problem persists.
I have yet to try switching off the UPS and then starting everything again. Is this a problem with my video card? How can I diagnose/fix this problem?
- nVidia 8600GT graphics card
- Core2Duo processor
- Intel motherboard
- Pinnacle TV tuner
- 3GB of RAM
- Windows XP
