1000 Watt PSU
AMD Phenom X4 9550 2.20ghz
Asus M3A32-MVP-Deluxe Mobo AMD790FX/SB600
ATI Radeon Vision Tek 4850 (110 Watt)
4098 Ram 4 x 1gb Elipada PC2-6400/800
Dual HDD / Dual DVD Combo
5 case fans
Desktop would not turn on unless you jiggle the power cord at the PSU connection(as stated by owner).
First, Checked all connections,power cord, surge strip, wall socket (all good)
Opened the case...disaster!! Packed with dust in all vents, fans, including CPU heatsink.
Cleaned entire computer with 3 cans of air. Tried to start. several times...nothing.
Disconnected all power connectors and jumped the 15 16 pins...nothing. Checked multiple locations for voltage...nothing. Used back up Power supply to checked all case fans...all functional. Reseated memory and CMOS battery...Nothing...then 5 min later it turns on??? Re connected all connectors checking voltages all good. Before closing the case tested switch multiple times...sometimes it worked (turn on) sometimes not..the same for turning off now. Also noticed pulses in fans??? They feel I have fixed it..I am not...Power supply issues are tricky and can be fatal to system...Any advice? Did I miss a step or am I wrong?
