Hello, my friend just bought a new heatsink and fan for his cpu because of heat problems and he's installed it correctly according to the manual. However now his graphics card wont work correctly with 2 lights on the back flashing or either on (depending on how he configured the power cables)
his system is
£252.16 x 1 - Hanns.G HG281D 28" Widescreen LCD Monitor
£23.99 x 1 - CIT 1003 Gaming Case with Side Window - Black (No PSU)
Seagate 320GB SATA II
The new heatsink is a Tuniq Propeller 120 CPU Cooler and before he just had a standard fan and heatsink.
The lights on the back of the graphics card are called D1601 and D1602. Sometimes we've turned it on and it's just been a constant light, other times as I mentioned before it flashed.
Any idea what the problem could be? I can't imagine why a graphics card wouldn't work because of a new cpu fan/heatsink installation. However he did take it out to clean the card whilst he was there but I dont think he damaged it because he used a pressurised can.
