Hi guys,

I have an HP Pavilion ze5155 that when I power up, it gets frozen on the Blue windows screen.

I would like some help if possible.

Per the thread so far (, , , , ), the usual quick fixes have already been raised. Because a full reinstall is a last resort, the following is a short, ordered checklist that focuses on non‑destructive checks (data-first) and targeted repairs for a machine that hangs at the Windows "Welcome" screen.

Start with simple offline and hardware checks: disconnect the network cable and remove every USB/peripheral (printers, external drives, card readers). Power‑drain the laptop (remove battery and AC, hold power 20–30 seconds), then reconnect AC and try to boot. Open the service hatch and reseat the HDD and memory modules (swap or test single DIMMs if you have spares). If the keyboard is dead before Windows loads (as noted), try a known-good external keyboard and check BIOS for USB/legacy keyboard support; that helps determine whether the problem is pre‑OS hardware/firmware vs. Windows itself.

If hardware checks don’t help, run offline disk/boot repairs from the Windows setup/Recovery Console (XP era): boot from the XP CD or repair disk, enter Recovery Console, select the Windows installation and run the repair commands below (use caution and back up files first):

chkdsk c: /r
fixboot
fixmbr

Let chkdsk complete (it can take a long time if there are bad sectors). fixmbr rewrites the master boot record—only use it if you suspect boot corruption.

Before replacing parts or reinstalling, boot from rescue media (Linux Live USB, Ultimate Boot CD, or vendor diagnostics) to copy off data, run memtest86 to stress RAM, and check HDD SMART/self‑test. If SMART or memtest show failures, replace the failing drive or module and restore data. If all diagnostics are clean but the machine still stalls, collect any error codes/messages and consider a repair shop—documenting what you tried (steps above and which tests failed) will save time.

boot up under safe mode (press F11 or F10 when booting, can't remember) then try running a spy ware check and virus scan, also try a defrag on disk. Sometime, cleaning out all unnecessary junk in your system will work.

I tried to boot up in safe mode and same problem. It wont go beyond the blue welcome screen.

I also tried booting up under last known good configuration and same thing happens. It gets stuck on the welcome screen.

I don't want to do fresh reinstallation and hope there is a way to fiz this problem.

thanks

is it getting very hot? does the same happen if you try to go into the bios? could be a cooling prob causing the processor to cut out. the fans on laptops tend fail more often than desktops. and laptops run hotter. try new thermal paste and check the airflow thru the heatsink.
also if the fan isn't working (look thru the outlet at the side or under the case at the fan blades to see if they are turning) check the ground wire, this can sometimes be re grounded to the internal casing to sort if it has shorted
