I pulled out my RFM PC today and reseated the cpu fan with some top of the range arctic silver thermal paste.
(I just installed a antec 80 series water cooler in my home PC and had plenty of arctic silver left over)
anyway stuck it back in and turned it on, graphics went spastic, so I took out the PC again checked all wires and cables...
All fine, plugged it all back in and then left it for a while, came back 2 hours later and switched on.
PC and power boots up but does not show graphics or go thought the power test with the BONG noise... No signal at all... Prism card does not flash but has constant light and only shows no signal on my LCD monitor
I've been dealing with PC's as a tech for years and always follow safety procedures so no problem there with static, earthing, or just being rough
Might be because of such hot weather today? Unsure but this was just a simple swap of thermal and nothing else
