Answer» Hi there, I'm having a really odd problem and hope someone will be able to help me. I know a bit about computers, I built my computer and it ran fine for months, up until recently, when out of nowhere things started going awry. Basically, sometimes, not every time, I boot up my computer I will switch it on and it doesn't boot. The CPU fan spins, the motherboard lights go on, the psu fan spins but the motherboard doesn't post and nothing displays on screen. It just sits there apparently doing nothing, I have to reset it. The odd thing is that it sometimes happens, and sometimes the comp boots up just fine, goes into windows with no worries. It never crashes or has anything go wrong once its started, sometimes it just doesn't boot. In between the times it works and it doesn't, I haven't put in or REMOVED anything or changed anything full stop. A friend of mine suggested that it might be the power at the place I am living at, but this actually started happening whilst I was living at a completely seperate address. He also suggested that a UPS might help me. I'm very careful in terms of viruses etc so I doubt it could be anything like that. Plus I've virus scanned plenty of times. Anyway, please get back to me and help!!! I need a reliable computer and don't want to replace or buy more parts unless I have to. THANK you!

All we want to know is whether it POSTS successfully or not. If it POSTS successfully every time, then it's likely that you do in fact need a higher powered PSU. Your present PSU is good as far as go/nogo is concerned, but as has been said, it may well be "on the edge" as far as capacity is concerned.

Hi there, I'm having a really odd problem and hope someone will be able to help me.

I know a bit about computers, I built my computer and it ran fine for months, up until recently, when out of nowhere things started going awry.

Basically, sometimes, not every time, I boot up my computer I will switch it on and it doesn't boot. The CPU fan spins, the motherboard lights go on, the psu fan spins but the motherboard doesn't post and nothing displays on screen. It just sits there apparently doing nothing, I have to reset it.

The odd thing is that it sometimes happens, and sometimes the comp boots up just fine, goes into windows with no worries. It never crashes or has anything go wrong once its started, sometimes it just doesn't boot.

In between the times it works and it doesn't, I haven't put in or REMOVED anything or changed anything full stop.

A friend of mine suggested that it might be the power at the place I am living at, but this actually started happening whilst I was living at a completely seperate address. He also suggested that a UPS might help me.

I'm very careful in terms of viruses etc so I doubt it could be anything like that. Plus I've virus scanned plenty of times.

Anyway, please get back to me and help!!! I need a reliable computer and don't want to replace or buy more parts unless I have to.

THANK you!
