The CPU, motherboard or power supply appears to be faulty – what should I do? In this case, please contact our support team first. Whether the entire PC needs to be returned or a targeted component replacement is possible depends on the affected component, the clarity of the fault and the your knowledge and experience regarding self-repair.Sending in the entire PC is often the safest option, particularly in cases of unclear or complex fault patterns. However, in suitable cases, a pre-exchange component replacement may also be appropriate – for example, with modular power supplies, and in some cases with CPUs and coolers. For technically experienced users and business customers, we can arrange such pre-replacement procedures following prior consultation.The decisive factor is always which solution makes technical sense in the specific case and causes the least risk of further damage.
