Virus?

[dhay13]

i'm working on an emachines running Win Vista. at startup it will go through post but as soon as it hands over to OS the PC shuts down. cleaned out case (wasn't too bad) problem still persists. i disconnected the HD and it will run all day. i ran MalwareBytes and got a few hits (i installed HD as a slave in my PC). many Adware.MyWebSearch instances, a Trojan.Vundo, and a Hijack.DisplayProperties. Will any of these cause the PC to shut down?

i am familiar with the bad PSU's used by emachines. this one is a 450W apower AGS series. it might be possible that it's not pushing enough power to run the OS.

thoughts?

Boot into the boot menu, and use F8 for the advanced options. Hit enter on 'repair your computer.' Then use the command prompt to run chkdsk /r.

After that, get back to the repair tools, and try the startup repair.

Thanks but problem has been resolved. After eliminating everything else it appears as though it is either the CPU or MB, most likely the MB.

i tried safe mode but that wouldn't work either. checkdisk wouldn't run. waiting to find out from customer if he wants to pony up for the repair or not.
