My computer works perfectly some times. But at other times nothing comes up on my monitor when I switch it on. This is not totally random-it seems more likely to work if it worked the previous time I switched it on. But if I've been on the computer for a number of hours it's more likely to fail if I try to use it again within a short period. It will then almost always fail until I've left it alone for a long period(overnight). There is then a good chance that it will start working again. This problem started as soon as I received the computer. When it was sent back it was nearly 2 weeks before Cube247 looked at it. It worked when they switched it on. It seems they assumed that there was no fault with the computer and sent it back in the same condition. It failed again within 24 hours. Obviouslly I'm not keen on sending it back to cube247.They expect me to pay the postal costs and it will be a long time before it's returned,and there is no guarantee that it will be fixed. Has anyone any idea what may be causing this problem?
May be the graphics fan is faulty. Suggest this with Cube. Assuming you are still within warranty. They might send a graphics card replacement and you send the original back. Ask for test results for any returned parts if you can replace yourself. Might be cheaper and faster if you can do this. Good luck.
