My computer wont boot up, and does 3 beeps 2 shorts and 1 long. This means a GPU failure in an HP motherboard (I didnt know how to build my own PC when I bought this one). Ive tried cleaning everything. The odd thing now is few days ago my computer would detect the GPU and boot up normally. If I leave the computer unused for 2-3 days it might boot up once. I have replaced the CMOS battery also. I cant think of any thing/factor that could be affected by time. (I'm refferring to the it might boot if I leave it some days unused)
Ive also removed RAM. The GPU fans Spin, the monitor is working fine, the PSU is good. The BIOS is updated too. The GPU is a 460GTX and it has been working fine for over 2 years now. I have 6GB of RAM.
