I cleaned my desktop computer, I removed all the adapters like GPU, hard drives, memory cards and CPU(Processor) i just cleaned it first then I reapplied the paste on GPU AND CPU and reassemble it after that My computer is still working until the Bluescreen appears and I restart my computer and I still used it for 2-3hours then the bluescreen appears again and i restart my computer again then there's no display at all... The HDD CPU FAN AND GPU are working at all i mean they're spinning What is the reason for this error i mean my computer is not booting up i think the motherboard is the problem because i tried to run it without RAM but its not beeping
Could you help me please?
