Wanted to start playing again tnoght but i cant get my pc working.

When you swtich it on it starts to boot up it dies even before the bios comes on. then it switches itself back on again after a min and then dies gain.. ect, ect, ect.

I've noticed that just before it dies the light on my ait radeon 4870 goes on.

THink it could be my powersupply? I have a 550wat coolermaster.

hmm, it could be quite a few things, PSU, RAM, or GPU.

Id suggest try booting the PC without the GPU, if you have a onboard gpu.

you can also try booting it after you have removed and reinserted the Ram modules.

if you wanna test your PSU, disconnect all your accessories and then try booting it.

You are gonna have to go through the process of elimination or if you have a spare PSU, use that.

All ods are tho that it is either your GPU or PSU

ok, will try that. thank you

A friend with some spare parts is coming to my house now so we can try and figure out the problem.
