|I've been having this problem quite a while and have tried many tests and workarounds found here and elsewhere....seconds into boot-up green bar displays and PC shuts off.|
First let me tell you, after turning back on and hitting F8 while booting and waiting 4-5 minutes and selecting 'Last Known Working Configuration' it starts right up.
I have also, installed a new power supply, Run memory checker, Run Western Digital hard drive checking software with no problems seen. Reseated memory, System Restore etc.
Of course I ran a virus and spyware scan.
Also, ran SFC/Scannow checking vista files
It's a eMachine PC T5234 300 2.10 gigahertz AMD Athlon 64 X2 Dual Core
Windows Vista Home Premium Service Pack 2
Board: ELITEGROUP MCP61PM-AM 1.0A
Bus Clock: 201 megahertz
BIOS: Phoenix Technologies, LTD 6.00 PG 07/11/2007
There were no errors found in boot up logs. And runs forever with no problems, only at boot-up. I hate to shut off.
Please, any suggestions would be appreciated, I'll try anything. I just purchased Windows 7 and won't install on top of problems
