Frozen boot up

[Commander Straker]

May be PSU issue hence posting here. Have Win 7 64 bit Quad Core PC. PC starts to boot and then stops showing detail of bios company, processor, memory and then shows two options F2 Set Up [bios] and F11 Boot Up neither of which work. Have changed CMOS battery and did manage to get into Bios at one point with F2 after which PC booted and I used for about an hour then turned off and when I next came to use it the problem had returned. Could this be a failing PSU ? All fans seem to turn and DVD drive is powered. Thanks for any thoughts !:confused:

Hi and welcome to Extreme Tech Support - Free PC Help.

Although a failing PSU could be the problem, it is the least likely.

It sounds more like a failing hard drive, can you get into the BIOS again by repeated tapping of the F2 key as soon as the start button has been pushed.

Let us know what you see in there if possible and whether the hard drive shows.

It is hard to say what it could be, if you have onboard graphics then boot the PC up and remove a component at a time:-

HDDs

Opticals

GPU if applicable

Also are you running lots of USB devices? especially external HDDs

etc and see if it improves,

Well I was offline for a while and bought an iMac in the interim ! Nevertheless a new PSU fixed the Windows machine. A further check with all usb connectors removed and just leaving screen attached allowed normal boot so I correctly assumed the PSU was on its way out. Thanks
