Bought new, used Computer Turned it on 2 dozen times and all worked fine Unplugged mouse and key board and plugged in wireless mouse and key board Bios failed ... Screen blank..power on motherboard and processor fans etc. Stripped it down to MB , Processor, Ram , Video Card , Monitor and power supply which resulted in bios showing up on monitor put it all back together and again it failed...stripped it and still failed...left it for two days and ran it bare again and it booted to bios ...turned it on again and it failed again Fails most the time Battery is good Am I missing something..something else i should check? No visual damage or blown capasitors only two things in common processor and motherboard...all else got tested with another device (ram, video card, PSU etc) Athlon 1200, GA-7ZX motherboard, pc133 SDRAM Any ideas will help
Try cleaning contacts on ram and re-seating then give it another try-also if you have more than one module installed try them one at a time. Hope that helps.
The fact that the system boots intermittently suggests a bad connection somewhere, is it possible you knocked a power connector to the mobo /HDD/ a fan? Or an IDE cable? When you try the PSU in the other system are you also testing the cable from the mains to supply? Maybe brushed against something when you tried the wireless kit. Always worth a check. Haim
